-    When |cmd| is a sequence, it is assumed to contain the name of the command
-    to run followed by its arguments. In this case, arguments are passed to the
-    command exactly as given, preventing any further processing by the shell.
-    This allows callers to easily pass arguments with spaces or special
-    characters without having to worry about quoting rules. Whenever possible,
-    it is recomended to pass |cmd| as a sequence.

-    When |cmd| is passed as a single string, |shell| should be set to True.
-    The command will be interpreted and run by the shell on the device,
-    allowing the use of shell features such as pipes, wildcards, or variables.
-    Failing to set shell=True will issue a warning, but this will be changed

+### DeviceUtils.SetWebViewFallbackLogic
+
+Set whether WebViewUpdateService's "fallback logic" should be enabled.

+    WebViewUpdateService has nonintuitive "fallback logic" for devices where
+    Monochrome (Chrome Stable) is preinstalled as the WebView provider, with a
+    "stub" (little-to-no code) implementation of standalone WebView.
+
+    "Fallback logic" (enabled by default) is designed, in the case where the
+    user has disabled Chrome, to fall back to the stub standalone WebView by
+    enabling the package. The implementation plumbs through the Chrome APK until
+    Play Store installs an update with the full implementation.
+
+    A surprising side-effect of "fallback logic" is that, immediately after
+    sideloading WebView, WebViewUpdateService re-disables the package and
+    uninstalls the update. This can prevent successfully using standalone
+    WebView for development, although "fallback logic" can be disabled on
+    userdebug/eng devices.
+
+    Because this is only relevant for devices with the standalone WebView stub,
+    this command is only relevant on N-P (inclusive).
+
+    You can determine if "fallback logic" is currently enabled by checking
+    FallbackLogicEnabled in the dictionary returned by
+    GetWebViewUpdateServiceDump.

+
+
+## &lt;app-route&gt;
+
+`app-route` is an element that enables declarative, self-describing routing
+for a web app.
+
+> *n.b. app-route is still in beta. We expect it will need some changes. We're counting on your feedback!*
+
+In its typical usage, a `app-route` element consumes an object that describes
+some state about the current route, via the `route` property. It then parses
+that state using the `pattern` property, and produces two artifacts: some `data`
+related to the `route`, and a `tail` that contains the rest of the `route` that
+did not match.
+
+Here is a basic example, when used with `app-location`:
+
+```html
+<app-location route="{{route}}"></app-location>
+<app-route
+    route="{{route}}"
+    pattern="/:page"
+    data="{{data}}"
+    tail="{{tail}}">
+</app-route>
+```
+
+In the above example, the `app-location` produces a `route` value. Then, the
+`route.path` property is matched by comparing it to the `pattern` property. If
+the `pattern` property matches `route.path`, the `app-route` will set or update
+its `data` property with an object whose properties correspond to the parameters
+in `pattern`. So, in the above example, if `route.path` was `'/about'`, the value
+of `data` would be `{"page": "about"}`.
+
+The `tail` property represents the remaining part of the route state after the
+`pattern` has been applied to a matching `route`.
+
+Here is another example, where `tail` is used:
+
+```html
+<app-location route="{{route}}"></app-location>
+<app-route
+    route="{{route}}"
+    pattern="/:page"
+    data="{{routeData}}"
+    tail="{{subroute}}">
+</app-route>
+<app-route
+    route="{{subroute}}"
+    pattern="/:id"
+    data="{{subrouteData}}">
+</app-route>
+```
+
+In the above example, there are two `app-route` elements. The first
+`app-route` consumes a `route`. When the `route` is matched, the first
+`app-route` also produces `routeData` from its `data`, and `subroute` from
+its `tail`. The second `app-route` consumes the `subroute`, and when it
+matches, it produces an object called `subrouteData` from its `data`.
+
+So, when `route.path` is `'/about'`, the `routeData` object will look like
+this: `{ page: 'about' }`
+
+And `subrouteData` will be null. However, if `route.path` changes to
+`'/article/123'`, the `routeData` object will look like this:
+`{ page: 'article' }`
+
+And the `subrouteData` will look like this: `{ id: '123' }`
+
+`app-route` is responsive to bi-directional changes to the `data` objects
+they produce. So, if `routeData.page` changed from `'article'` to `'about'`,
+the `app-route` will update `route.path`. This in-turn will update the
+`app-location`, and cause the global location bar to change its value.
+
+
+
+## &lt;app-location&gt;
+
+`app-location` is an element that provides synchronization between the
+browser location bar and the state of an app. When created, `app-location`
+elements will automatically watch the global location for changes. As changes
+occur, `app-location` produces and updates an object called `route`. This
+`route` object is suitable for passing into a `app-route`, and other similar
+elements.
+
+An example of the public API of a route object that describes the URL
+`https://elements.polymer-project.org/elements/app-location`:
+
+```css
+{
+  prefix: '',
+  path: '/elements/app-location'
+}
+```
+
+Example Usage:
+
+```html
+<app-location route="{{route}}"></app-location>
+<app-route route="{{route}}" pattern="/:page" data="{{data}}"></app-route>
+```
+
+As you can see above, the `app-location` element produces a `route` and that
+property is then bound into the `app-route` element. The bindings are two-
+directional, so when changes to the `route` object occur within `app-route`,
+they automatically reflect back to the global location.
+
+### Hashes vs Paths
+
+By default `app-location` routes using the pathname portion of the URL. This has
+broad browser support but it does require cooperation of the backend server. An
+`app-location` can be configured to use the hash part of a URL instead using
+the `use-hash-as-path` attribute, like so:
+
+```html
+<app-location route="{{route}}" use-hash-as-path></app-location>
+```
+
+### Integrating with other routing code
+
+There is no standard event that is fired when window.location is modified.
+`app-location` fires a `location-changed` event on `window` when it updates the
+location. It also listens for that same event, and re-reads the URL when it's
+fired. This makes it very easy to interop with other routing code.
+
+So for example if you want to navigate to `/new_path` imperatively you could
+call `window.location.pushState` or `window.location.replaceState` followed by
+firing a `location-changed` event on `window`. i.e.
+
+```javascript
+window.history.pushState({}, null, '/new_path');
+window.dispatchEvent(new CustomEvent('location-changed'));
+```
+
+
+
+## &lt;app-route-converter&gt;
+
+`app-route-converter` provides a means to convert a path and query
+parameters into a route object and vice versa. This produced route object
+is to be fed into route-consuming elements such as `app-route`.
+
+> n.b. This element is intended to be a primitive of the routing system and for
+creating bespoke routing solutions from scratch. To simply include routing in
+an app, please refer to [app-location](https://github.com/PolymerElements/app-route/blob/master/app-location.html)
+and [app-route](https://github.com/PolymerElements/app-route/blob/master/app-route.html).
+
+An example of a route object that describes
+`https://elements.polymer-project.org/elements/app-route-converter?foo=bar&baz=qux`
+and should be passed to other `app-route` elements:
+
+```css
+{
+  prefix: '',
+  path: '/elements/app-route-converter',
+  __queryParams: {
+    foo: 'bar',
+    baz: 'qux'
+  }
+}
+```
+
+`__queryParams` is private to discourage directly data-binding to it. This is so
+that routing elements like `app-route` can intermediate changes to the query
+params and choose whether to propagate them upstream or not. `app-route` for
+example will not propagate changes to its `queryParams` property if it is not
+currently active. A public queryParams object will also be produced in which you
+should perform data-binding operations.
+
+Example Usage:
+
+```html
+<iron-location path="{{path}}" query="{{query}}"></iron-location>
+<iron-query-params
+    params-string="{{query}}"
+    params-object="{{queryParams}}">
+</iron-query-params>
+<app-route-converter
+    path="{{path}}"
+    query-params="{{queryParams}}"
+    route="{{route}}">
+</app-route-converter>
+<app-route route='{{route}}' pattern='/:page' data='{{data}}'>
+</app-route>
+```
+
+This is a simplified implementation of the `app-location` element. Here the
+`iron-location` produces a path and a query, the `iron-query-params` consumes
+the query and produces a queryParams object, and the `app-route-converter`
+consumes the path and the query params and converts it into a route which is in
+turn is consumed by the `app-route`.
+
+
+
+## Polymer.AppRouteConverterBehavior
+
+Provides bidirectional mapping between `path` and `queryParams` and a
+app-route compatible `route` object.
+
+For more information, see the docs for `app-route-converter`.

+`app-route-converter` provides a means to convert a path and query
+parameters into a route object and vice versa. This produced route object
+is to be fed into route-consuming elements such as `app-route`.
+
+> n.b. This element is intended to be a primitive of the routing system and for
+creating bespoke routing solutions from scratch. To simply include routing in
+an app, please refer to [app-location](https://github.com/PolymerElements/app-route/blob/master/app-location.html)
+and [app-route](https://github.com/PolymerElements/app-route/blob/master/app-route.html).
+
+An example of a route object that describes
+`https://elements.polymer-project.org/elements/app-route-converter?foo=bar&baz=qux`
+and should be passed to other `app-route` elements:
+
+    {
+      prefix: '',
+      path: '/elements/app-route-converter',
+      __queryParams: {
+        foo: 'bar',
+        baz: 'qux'
+      }
+    }
+
+`__queryParams` is private to discourage directly data-binding to it. This is so
+that routing elements like `app-route` can intermediate changes to the query
+params and choose whether to propagate them upstream or not. `app-route` for
+example will not propagate changes to its `queryParams` property if it is not
+currently active. A public queryParams object will also be produced in which you
+should perform data-binding operations.
+
+Example Usage:
+
+    <iron-location path="{{path}}" query="{{query}}"></iron-location>
+    <iron-query-params
+        params-string="{{query}}"
+        params-object="{{queryParams}}">
+    </iron-query-params>
+    <app-route-converter
+        path="{{path}}"
+        query-params="{{queryParams}}"
+        route="{{route}}">
+    </app-route-converter>
+    <app-route route='{{route}}' pattern='/:page' data='{{data}}'>
+    </app-route>
+
+This is a simplified implementation of the `app-location` element. Here the
+`iron-location` produces a path and a query, the `iron-query-params` consumes
+the query and produces a queryParams object, and the `app-route-converter`
+consumes the path and the query params and converts it into a route which is in
+turn is consumed by the `app-route`.

+`app-route` is an element that enables declarative, self-describing routing
+for a web app.
+
+> *n.b. app-route is still in beta. We expect it will need some changes. We're counting on your feedback!*
+
+In its typical usage, a `app-route` element consumes an object that describes
+some state about the current route, via the `route` property. It then parses
+that state using the `pattern` property, and produces two artifacts: some `data`
+related to the `route`, and a `tail` that contains the rest of the `route` that
+did not match.
+
+Here is a basic example, when used with `app-location`:
+
+    <app-location route="{{route}}"></app-location>
+    <app-route
+        route="{{route}}"
+        pattern="/:page"
+        data="{{data}}"
+        tail="{{tail}}">
+    </app-route>
+
+In the above example, the `app-location` produces a `route` value. Then, the
+`route.path` property is matched by comparing it to the `pattern` property. If
+the `pattern` property matches `route.path`, the `app-route` will set or update
+its `data` property with an object whose properties correspond to the parameters
+in `pattern`. So, in the above example, if `route.path` was `'/about'`, the value
+of `data` would be `{"page": "about"}`.
+
+The `tail` property represents the remaining part of the route state after the
+`pattern` has been applied to a matching `route`.
+
+Here is another example, where `tail` is used:
+
+    <app-location route="{{route}}"></app-location>
+    <app-route
+        route="{{route}}"
+        pattern="/:page"
+        data="{{routeData}}"
+        tail="{{subroute}}">
+    </app-route>
+    <app-route
+        route="{{subroute}}"
+        pattern="/:id"
+        data="{{subrouteData}}">
+    </app-route>
+
+In the above example, there are two `app-route` elements. The first
+`app-route` consumes a `route`. When the `route` is matched, the first
+`app-route` also produces `routeData` from its `data`, and `subroute` from
+its `tail`. The second `app-route` consumes the `subroute`, and when it
+matches, it produces an object called `subrouteData` from its `data`.
+
+So, when `route.path` is `'/about'`, the `routeData` object will look like
+this: `{ page: 'about' }`
+
+And `subrouteData` will be null. However, if `route.path` changes to
+`'/article/123'`, the `routeData` object will look like this:
+`{ page: 'article' }`
+
+And the `subrouteData` will look like this: `{ id: '123' }`
+
+`app-route` is responsive to bi-directional changes to the `data` objects
+they produce. So, if `routeData.page` changed from `'article'` to `'about'`,
+the `app-route` will update `route.path`. This in-turn will update the
+`app-location`, and cause the global location bar to change its value.

+The `core-tooltip` element creates a hover tooltip centered for the content
+it contains. It can be positioned on the top|bottom|left|right of content using
+the `position` attribute.
+
+To include HTML in the tooltip, include the `tip` attribute on the relevant
+content.
+
+<b>Example</b>:
+
+    <core-tooltip label="I'm a tooltip">
+      <span>Hover over me.</span>
+    </core-tooltip>
+
+<b>Example</b> - positioning the tooltip to the right:
+
+    <core-tooltip label="I'm a tooltip to the right" position="right">
+      <core-icon-button icon="drawer"></core-icon-button>
+    </core-tooltip>
+
+<b>Example</b> - no arrow and showing by default:
+
+    <core-tooltip label="Tooltip with no arrow and always on" noarrow show>
+      <img src="image.jpg">
+    </core-tooltip>
+
+<b>Example</b> - disable the tooltip.
+
+    <core-tooltip label="Disabled label never shows" disabled>
+      ...
+    </core-tooltip>
+
+<b>Example</b> - rich tooltip using the `tip` attribute:
+
+    <core-tooltip>
+      <div>Example of a rich information tooltip</div>
+      <div tip>
+        <img src="profile.jpg">Foo <b>Bar</b> - <a href="#">@baz</a>
+      </div>
+    </core-tooltip>
+
+By default, the `tip` attribute specifies the HTML content for a rich tooltip.
+You can customize this attribute with the `tipAttribute` attribute:
+
+    <core-tooltip tipAttribute="htmltooltip">
+      <div>Example of a rich information tooltip</div>
+      <div htmltooltip>
+        ...
+      </div>

+# Polymer Elements
+## Guide for Contributors
+
+Polymer Elements are built in the open, and the Polymer authors eagerly encourage any and all forms of community contribution. When contributing, please follow these guidelines:
+
+### Filing Issues
+
+**If you are filing an issue to request a feature**, please provide a clear description of the feature. It can be helpful to describe answers to the following questions:
+
+ 1. **Who will use the feature?** _“As someone filling out a form…”_
+ 2. **When will they use the feature?** _“When I enter an invalid value…”_
+ 3. **What is the user’s goal?** _“I want to be visually notified that the value needs to be corrected…”_
+
+**If you are filing an issue to report a bug**, please provide:
+
+ 1. **A clear description of the bug and related expectations.** Consider using the following example template for reporting a bug:
+
+ ```markdown
+ The `paper-foo` element causes the page to turn pink when clicked.
+
+ ## Expected outcome
+
+ The page stays the same color.
+
+ ## Actual outcome
+
+ The page turns pink.
+
+ ## Steps to reproduce
+
+ 1. Put a `paper-foo` element in the page.
+ 2. Open the page in a web browser.
+ 3. Click the `paper-foo` element.
+ ```
+
+ 2. **A reduced test case that demonstrates the problem.** If possible, please include the test case as a JSBin. Start with this template to easily import and use relevant Polymer Elements: [https://jsbin.com/cagaye/edit?html,output](https://jsbin.com/cagaye/edit?html,output).
+
+ 3. **A list of browsers where the problem occurs.** This can be skipped if the problem is the same across all browsers.
+
+### Submitting Pull Requests
+
+**Before creating a pull request**, please ensure that an issue exists for the corresponding change in the pull request that you intend to make. **If an issue does not exist, please create one per the guidelines above**. The goal is to discuss the design and necessity of the proposed change with Polymer authors and community before diving into a pull request.
+
+When submitting pull requests, please provide:
+
+ 1. **A reference to the corresponding issue** or issues that will be closed by the pull request. Please refer to these issues in the pull request description using the following syntax:
+
+ ```markdown
+ (For a single issue)
+ Fixes #20
+
+ (For multiple issues)
+ Fixes #32, fixes #40
+ ```
+
+ 2. **A succinct description of the design** used to fix any related issues. For example:
+
+ ```markdown
+ This fixes #20 by removing styles that leaked which would cause the page to turn pink whenever `paper-foo` is clicked.
+ ```
+
+ 3. **At least one test for each bug fixed or feature added** as part of the pull request. Pull requests that fix bugs or add features without accompanying tests will not be considered.
+
+If a proposed change contains multiple commits, please [squash commits](https://www.google.com/url?q=http://blog.steveklabnik.com/posts/2012-11-08-how-to-squash-commits-in-a-github-pull-request) to as few as is necessary to succinctly express the change. A Polymer author can help you squash commits, so don’t be afraid to ask us if you need help with that!

+/**
+`google-signin-aware` is used to enable authentication in custom elements by
+interacting with a google-signin element that needs to be present somewhere
+on the page.
+
+The `scopes` attribute allows you to specify which scope permissions are required
+(e.g do you want to allow interaction with the Google Drive API).
+
+The `google-signin-aware-success` event is triggered when a user successfully
+authenticates. If either `offline` or `offlineAlwaysPrompt` is set to true, successful
+authentication will also trigger the `google-signin-offline-success`event.
+The `google-signin-aware-signed-out` event is triggered when a user explicitly
+signs out via the google-signin element.
+
+You can bind to `isAuthorized` property to monitor authorization state.

+
+If you do not need to show the button, use companion `<google-signin-aware>` element to declare scopes, check authentication state.
+
+#### Examples
+
+    <google-signin client-id="..." scopes="https://www.googleapis.com/auth/drive"></google-signin>
+
+    <google-signin label-signin="Sign-in" client-id="..." scopes="https://www.googleapis.com/auth/drive"></google-signin>
+
+    <google-signin theme="dark" width="iconOnly" client-id="..." scopes="https://www.googleapis.com/auth/drive"></google-signin>
+
+
+#### Notes
+
+The attribute `clientId` is provided in your Google Developers Console
+(https://console.developers.google.com).
+
+The `scopes` attribute allows you to specify which scope permissions are required
+(e.g do you want to allow interaction with the Google Drive API). Many APIs also
+need to be enabled in the Google Developers Console before you can use them.
+
+The `requestVisibleActions` attribute is necessary if you want to write app
+activities (https://developers.google.com/+/web/app-activities/) on behalf of
+the user. Please note that this attribute is only valid in combination with the
+plus.login scope (https://www.googleapis.com/auth/plus.login).
+
+The `offline` attribute allows you to get an auth code which your server can
+redeem for an offline access token
+(https://developers.google.com/identity/sign-in/web/server-side-flow).
+You can also set `offline-always-prompt` instead of `offline` to ensure that your app
+will re-prompt the user for offline access and generate a working `refresh_token`
+even if they have already granted offline access to your app in the past.
+
+Use label properties to customize prompts.
+
+The button can be styled in using the `height`, `width`, and `theme` attributes.
+These attributes help you follow the Google+ Sign-In button branding guidelines
+(https://developers.google.com/+/branding-guidelines).
+
+The `google-signin-success` event is triggered when a user successfully authenticates
+and `google-signed-out` is triggered when user signs out.
+You can also use `isAuthorized` attribute to observe user's authentication state.
+
+Additional events, such as `google-signout-attempted` are
+triggered when the user attempts to sign-out and successfully signs out.
+
+When requesting offline access, the `google-signin-offline-success` event is
+triggered when the user successfully consents with offline support.
+
+The `google-signin-necessary` event is fired when scopes requested via
+google-signin-aware elements require additional user permissions.
+
+#### Testing
+
+By default, the demo accompanying this element is setup to work on localhost with
+port 8080. That said, you *should* update the `clientId` to your own one for
+any apps you're building. See the Google Developers Console
+(https://console.developers.google.com) for more info.

+# Polymer Elements
+## Guide for Contributors
+
+Polymer Elements are built in the open, and the Polymer authors eagerly encourage any and all forms of community contribution. When contributing, please follow these guidelines:
+
+### Filing Issues
+
+**If you are filing an issue to request a feature**, please provide a clear description of the feature. It can be helpful to describe answers to the following questions:
+
+ 1. **Who will use the feature?** _“As someone filling out a form…”_
+ 2. **When will they use the feature?** _“When I enter an invalid value…”_
+ 3. **What is the user’s goal?** _“I want to be visually notified that the value needs to be corrected…”_
+
+**If you are filing an issue to report a bug**, please provide:
+
+ 1. **A clear description of the bug and related expectations.** Consider using the following example template for reporting a bug:
+
+ ```markdown
+ The `paper-foo` element causes the page to turn pink when clicked.
+
+ ## Expected outcome
+
+ The page stays the same color.
+
+ ## Actual outcome
+
+ The page turns pink.
+
+ ## Steps to reproduce
+
+ 1. Put a `paper-foo` element in the page.
+ 2. Open the page in a web browser.
+ 3. Click the `paper-foo` element.
+ ```
+
+ 2. **A reduced test case that demonstrates the problem.** If possible, please include the test case as a JSBin. Start with this template to easily import and use relevant Polymer Elements: [https://jsbin.com/cagaye/edit?html,output](https://jsbin.com/cagaye/edit?html,output).
+
+ 3. **A list of browsers where the problem occurs.** This can be skipped if the problem is the same across all browsers.
+
+### Submitting Pull Requests
+
+**Before creating a pull request**, please ensure that an issue exists for the corresponding change in the pull request that you intend to make. **If an issue does not exist, please create one per the guidelines above**. The goal is to discuss the design and necessity of the proposed change with Polymer authors and community before diving into a pull request.
+
+When submitting pull requests, please provide:
+
+ 1. **A reference to the corresponding issue** or issues that will be closed by the pull request. Please refer to these issues in the pull request description using the following syntax:
+
+ ```markdown
+ (For a single issue)
+ Fixes #20
+
+ (For multiple issues)
+ Fixes #32, fixes #40
+ ```
+
+ 2. **A succinct description of the design** used to fix any related issues. For example:
+
+ ```markdown
+ This fixes #20 by removing styles that leaked which would cause the page to turn pink whenever `paper-foo` is clicked.
+ ```
+
+ 3. **At least one test for each bug fixed or feature added** as part of the pull request. Pull requests that fix bugs or add features without accompanying tests will not be considered.
+
+If a proposed change contains multiple commits, please [squash commits](https://www.google.com/url?q=http://blog.steveklabnik.com/posts/2012-11-08-how-to-squash-commits-in-a-github-pull-request) to as few as is necessary to succinctly express the change. A Polymer author can help you squash commits, so don’t be afraid to ask us if you need help with that!

+##&lt;iron-a11y-announcer&gt;
+
+`iron-a11y-announcer` is a singleton element that is intended to add a11y
+to features that require on-demand announcement from screen readers. In
+order to make use of the announcer, it is best to request its availability
+in the announcing element.
+
+Example:
+
+```javascript
+Polymer({
+
+  is: 'x-chatty',
+
+  attached: function() {
+    // This will create the singleton element if it has not
+    // been created yet:
+    Polymer.IronA11yAnnouncer.requestAvailability();
+  }
+});
+```
+
+After the `iron-a11y-announcer` has been made available, elements can
+make announces by firing bubbling `iron-announce` events.
+
+Example:
+
+```javascript
+this.fire('iron-announce', {
+  text: 'This is an announcement!'
+}, { bubbles: true });
+```
+
+Note: announcements are only audible if you have a screen reader enabled.
+

+`iron-a11y-announcer` is a singleton element that is intended to add a11y
+to features that require on-demand announcement from screen readers. In
+order to make use of the announcer, it is best to request its availability
+in the announcing element.
+
+Example:
+
+    Polymer({
+
+      is: 'x-chatty',
+
+      attached: function() {
+        // This will create the singleton element if it has not
+        // been created yet:
+        Polymer.IronA11yAnnouncer.requestAvailability();
+      }
+    });
+
+After the `iron-a11y-announcer` has been made available, elements can
+make announces by firing bubbling `iron-announce` events.
+
+Example:
+
+    this.fire('iron-announce', {
+      text: 'This is an announcement!'
+    }, { bubbles: true });
+
+Note: announcements are only audible if you have a screen reader enabled.

+# Polymer Elements
+## Guide for Contributors
+
+Polymer Elements are built in the open, and the Polymer authors eagerly encourage any and all forms of community contribution. When contributing, please follow these guidelines:
+
+### Filing Issues
+
+**If you are filing an issue to request a feature**, please provide a clear description of the feature. It can be helpful to describe answers to the following questions:
+
+ 1. **Who will use the feature?** _“As someone filling out a form…”_
+ 2. **When will they use the feature?** _“When I enter an invalid value…”_
+ 3. **What is the user’s goal?** _“I want to be visually notified that the value needs to be corrected…”_
+
+**If you are filing an issue to report a bug**, please provide:
+
+ 1. **A clear description of the bug and related expectations.** Consider using the following example template for reporting a bug:
+
+ ```markdown
+ The `paper-foo` element causes the page to turn pink when clicked.
+
+ ## Expected outcome
+
+ The page stays the same color.
+
+ ## Actual outcome
+
+ The page turns pink.
+
+ ## Steps to reproduce
+
+ 1. Put a `paper-foo` element in the page.
+ 2. Open the page in a web browser.
+ 3. Click the `paper-foo` element.
+ ```
+
+ 2. **A reduced test case that demonstrates the problem.** If possible, please include the test case as a JSBin. Start with this template to easily import and use relevant Polymer Elements: [https://jsbin.com/cagaye/edit?html,output](https://jsbin.com/cagaye/edit?html,output).
+
+ 3. **A list of browsers where the problem occurs.** This can be skipped if the problem is the same across all browsers.
+
+### Submitting Pull Requests
+
+**Before creating a pull request**, please ensure that an issue exists for the corresponding change in the pull request that you intend to make. **If an issue does not exist, please create one per the guidelines above**. The goal is to discuss the design and necessity of the proposed change with Polymer authors and community before diving into a pull request.
+
+When submitting pull requests, please provide:
+
+ 1. **A reference to the corresponding issue** or issues that will be closed by the pull request. Please refer to these issues in the pull request description using the following syntax:
+
+ ```markdown
+ (For a single issue)
+ Fixes #20
+
+ (For multiple issues)
+ Fixes #32, fixes #40
+ ```
+
+ 2. **A succinct description of the design** used to fix any related issues. For example:
+
+ ```markdown
+ This fixes #20 by removing styles that leaked which would cause the page to turn pink whenever `paper-foo` is clicked.
+ ```
+
+ 3. **At least one test for each bug fixed or feature added** as part of the pull request. Pull requests that fix bugs or add features without accompanying tests will not be considered.
+
+If a proposed change contains multiple commits, please [squash commits](https://www.google.com/url?q=http://blog.steveklabnik.com/posts/2012-11-08-how-to-squash-commits-in-a-github-pull-request) to as few as is necessary to succinctly express the change. A Polymer author can help you squash commits, so don’t be afraid to ask us if you need help with that!

+##Polymer.IronA11yKeysBehavior
+
+`Polymer.IronA11yKeysBehavior` provides a normalized interface for processing
+keyboard commands that pertain to [WAI-ARIA best practices](http://www.w3.org/TR/wai-aria-practices/#kbd_general_binding).
+The element takes care of browser differences with respect to Keyboard events
+and uses an expressive syntax to filter key presses.
+
+Use the `keyBindings` prototype property to express what combination of keys
+will trigger the callback. A key binding has the format
+`"KEY+MODIFIER:EVENT": "callback"` (`"KEY": "callback"` or
+`"KEY:EVENT": "callback"` are valid as well). Some examples:
+
+```javascript
+ keyBindings: {
+   'space': '_onKeydown', // same as 'space:keydown'
+   'shift+tab': '_onKeydown',
+   'enter:keypress': '_onKeypress',
+   'esc:keyup': '_onKeyup'
+ }
+```
+
+The callback will receive with an event containing the following information in `event.detail`:
+
+```javascript
+ _onKeydown: function(event) {
+   console.log(event.detail.combo); // KEY+MODIFIER, e.g. "shift+tab"

+# Polymer Elements
+## Guide for Contributors
+
+Polymer Elements are built in the open, and the Polymer authors eagerly encourage any and all forms of community contribution. When contributing, please follow these guidelines:
+
+### Filing Issues
+
+**If you are filing an issue to request a feature**, please provide a clear description of the feature. It can be helpful to describe answers to the following questions:
+
+ 1. **Who will use the feature?** _“As someone filling out a form…”_
+ 2. **When will they use the feature?** _“When I enter an invalid value…”_
+ 3. **What is the user’s goal?** _“I want to be visually notified that the value needs to be corrected…”_
+
+**If you are filing an issue to report a bug**, please provide:
+
+ 1. **A clear description of the bug and related expectations.** Consider using the following example template for reporting a bug:
+
+ ```markdown
+ The `paper-foo` element causes the page to turn pink when clicked.
+
+ ## Expected outcome
+
+ The page stays the same color.
+
+ ## Actual outcome
+
+ The page turns pink.
+
+ ## Steps to reproduce
+
+ 1. Put a `paper-foo` element in the page.
+ 2. Open the page in a web browser.
+ 3. Click the `paper-foo` element.
+ ```
+
+ 2. **A reduced test case that demonstrates the problem.** If possible, please include the test case as a JSBin. Start with this template to easily import and use relevant Polymer Elements: [https://jsbin.com/zeriha/2/edit?html,output](https://jsbin.com/zeriha/2/edit?html,output).
+
+ 3. **A list of browsers where the problem occurs.** This can be skipped if the problem is the same across all browsers.
+
+### Submitting Pull Requests
+
+**Before creating a pull request**, please ensure that an issue exists for the corresponding change in the pull request that you intend to make. **If an issue does not exist, please create one per the guidelines above**. The goal is to discuss the design and necessity of the proposed change with Polymer authors and community before diving into a pull request.
+
+When submitting pull requests, please provide:
+
+ 1. **A reference to the corresponding issue** or issues that will be closed by the pull request. Please refer to these issues in the pull request description using the following syntax:
+
+ ```markdown
+ (For a single issue)
+ Fixes #20
+
+ (For multiple issues)
+ Fixes #32, fixes #40
+ ```
+
+ 2. **A succinct description of the design** used to fix any related issues. For example:
+
+ ```markdown
+ This fixes #20 by removing styles that leaked which would cause the page to turn pink whenever `paper-foo` is clicked.
+ ```
+
+ 3. **At least one test for each bug fixed or feature added** as part of the pull request. Pull requests that fix bugs or add features without accompanying tests will not be considered.
+
+If a proposed change contains multiple commits, please [squash commits](https://www.google.com/url?q=http://blog.steveklabnik.com/posts/2012-11-08-how-to-squash-commits-in-a-github-pull-request) to as few as is necessary to succinctly express the change. A Polymer author can help you squash commits, so don’t be afraid to ask us if you need help with that!

+_[Demo and API docs](https://elements.polymer-project.org/elements/iron-ajax)_
+
+## Changes in 2.0
+
+*   Promise polyfill is now a dev dependency and no longer shipped with `iron-ajax`.
+
+    `iron-ajax` uses the `Promise` API, which is not yet supported in all browsers.
+
+    The 1.x version of `iron-ajax` automatically loaded the promise polyfill. This 
+    forced the application to include the polyfill, whether or not it was needed.
+
+    When using `iron-ajax` 2.x with Polymer 1.x, you must provide your own Promise polyfill, 
+    if needed. For example, you could use the promise polyfill by installing it in your project:
+
+        bower install --save PolymerLabs/promise-polyfill#1 - 2
+
+    Then your app should include the promise polyfill before loading `iron-ajax`:
+
+        <link rel="import" href="bower_components/promise-polyfill/promise-polyfill-lite.html">
+
+    You can use a different promise polyfill if you need a more fully-featured implementation of 
+    Promise.
+
+    For Polymer 2.x, you **do not need to provide your own Promise polyfill if  you are using
+    the web components polyfills.** Because the web components v1 APIs depend on `Promise`, 
+    a promise polyfill is loaded when needed by the v1 polyfills (`web-components-lite.js` or 
+    `webcomponents-loader.js`).
+
+*   New optional error information.
+
+    The `generateRequest` method returns an `iron-request` element representing the 
+    request, and the request element provides a `completes` property, which is a 
+    promise that completes when the request either succeeds or fails.
+
+    This version includes a new flag, `rejectWithRequest`, that modifies the error handling
+    of the `completes` promise. By default, when the promise is rejected (because the request 
+    failed), the rejection callback only receives an `Error` object describing the failure.
+
+    With `rejectWithRequest` set to true, the callback receives an object with two keys, `error`, 
+    the error message, and `request`, the original request that the error is related to:
+
+        let request = ironAjaxElement.generateRequest();
+        request.completes.then(function(req) {
+            // succesful request, argument is iron-request element
+            ...
+          }, function(rejected) {
+            // failed request, argument is an object
+            let req = rejected.request;
+            let error = rejected.error;
+            ...
+          }
+        )
+
+    Because this change could break existing code, `rejectWithRequest` is false by default,
+    however, in the next major release, this option will be removed and the new behavior made 
+    the default.
+
+
+## &lt;iron-ajax&gt;
+
+The `iron-ajax` element exposes network request functionality.
+
+```html
+<iron-ajax
+    auto
+    url="https://www.googleapis.com/youtube/v3/search"
+    params='{"part":"snippet", "q":"polymer", "key": "YOUTUBE_API_KEY", "type": "video"}'
+    handle-as="json"
+    on-response="handleResponse"
+    debounce-duration="300"></iron-ajax>
+```
+
+With `auto` set to `true`, the element performs a request whenever
+its `url`, `params` or `body` properties are changed. Automatically generated
+requests will be debounced in the case that multiple attributes are changed
+sequentially.
+
+Note: The `params` attribute must be double quoted JSON.
+
+You can trigger a request explicitly by calling `generateRequest` on the
+element.
+
+
+
+## &lt;iron-request&gt;
+
+iron-request can be used to perform XMLHttpRequests.
+
+```html
+<iron-request id="xhr"></iron-request>
+...
+this.$.xhr.send({url: url, body: params});
+```

+With `auto` set to `true`, the element performs a request whenever

+requests will be debounced in the case that multiple attributes are changed
+sequentially.
+
+Note: The `params` attribute must be double quoted JSON.
+
+You can trigger a request explicitly by calling `generateRequest` on the
+element.

+# Polymer Elements
+## Guide for Contributors
+
+Polymer Elements are built in the open, and the Polymer authors eagerly encourage any and all forms of community contribution. When contributing, please follow these guidelines:
+
+### Filing Issues
+
+**If you are filing an issue to request a feature**, please provide a clear description of the feature. It can be helpful to describe answers to the following questions:
+
+ 1. **Who will use the feature?** _“As someone filling out a form…”_
+ 2. **When will they use the feature?** _“When I enter an invalid value…”_
+ 3. **What is the user’s goal?** _“I want to be visually notified that the value needs to be corrected…”_
+
+**If you are filing an issue to report a bug**, please provide:
+
+ 1. **A clear description of the bug and related expectations.** Consider using the following example template for reporting a bug:
+
+ ```markdown
+ The `paper-foo` element causes the page to turn pink when clicked.
+
+ ## Expected outcome
+
+ The page stays the same color.
+
+ ## Actual outcome
+
+ The page turns pink.
+
+ ## Steps to reproduce
+
+ 1. Put a `paper-foo` element in the page.
+ 2. Open the page in a web browser.
+ 3. Click the `paper-foo` element.
+ ```
+
+ 2. **A reduced test case that demonstrates the problem.** If possible, please include the test case as a JSBin. Start with this template to easily import and use relevant Polymer Elements: [https://jsbin.com/cagaye/edit?html,output](https://jsbin.com/cagaye/edit?html,output).
+
+ 3. **A list of browsers where the problem occurs.** This can be skipped if the problem is the same across all browsers.
+
+### Submitting Pull Requests
+
+**Before creating a pull request**, please ensure that an issue exists for the corresponding change in the pull request that you intend to make. **If an issue does not exist, please create one per the guidelines above**. The goal is to discuss the design and necessity of the proposed change with Polymer authors and community before diving into a pull request.
+
+When submitting pull requests, please provide:
+
+ 1. **A reference to the corresponding issue** or issues that will be closed by the pull request. Please refer to these issues in the pull request description using the following syntax:
+
+ ```markdown
+ (For a single issue)
+ Fixes #20
+
+ (For multiple issues)
+ Fixes #32, fixes #40
+ ```
+
+ 2. **A succinct description of the design** used to fix any related issues. For example:
+
+ ```markdown
+ This fixes #20 by removing styles that leaked which would cause the page to turn pink whenever `paper-foo` is clicked.
+ ```
+
+ 3. **At least one test for each bug fixed or feature added** as part of the pull request. Pull requests that fix bugs or add features without accompanying tests will not be considered.
+
+If a proposed change contains multiple commits, please [squash commits](https://www.google.com/url?q=http://blog.steveklabnik.com/posts/2012-11-08-how-to-squash-commits-in-a-github-pull-request) to as few as is necessary to succinctly express the change. A Polymer author can help you squash commits, so don’t be afraid to ask us if you need help with that!

+
+##&lt;iron-autogrow-textarea&gt;
+
+`iron-autogrow-textarea` is an element containing a textarea that grows in height as more
+lines of input are entered. Unless an explicit height or the `maxRows` property is set, it will
+never scroll.
+
+Example:
+
+```html
+<iron-autogrow-textarea></iron-autogrow-textarea>
+```
+
+### Styling
+
+The following custom properties and mixins are available for styling:
+
+| Custom property | Description | Default |
+| --- | --- | --- |
+| `--iron-autogrow-textarea` | Mixin applied to the textarea | `{}` |
+| `--iron-autogrow-textarea-placeholder` | Mixin applied to the textarea placeholder | `{}` |

+`iron-autogrow-textarea` is an element containing a textarea that grows in height as more
+lines of input are entered. Unless an explicit height or the `maxRows` property is set, it will
+never scroll.
+
+Example:
+
+    <iron-autogrow-textarea></iron-autogrow-textarea>
+
+### Styling

+# Polymer Elements
+## Guide for Contributors
+
+Polymer Elements are built in the open, and the Polymer authors eagerly encourage any and all forms of community contribution. When contributing, please follow these guidelines:
+
+### Filing Issues
+
+**If you are filing an issue to request a feature**, please provide a clear description of the feature. It can be helpful to describe answers to the following questions:
+
+ 1. **Who will use the feature?** _“As someone filling out a form…”_
+ 2. **When will they use the feature?** _“When I enter an invalid value…”_
+ 3. **What is the user’s goal?** _“I want to be visually notified that the value needs to be corrected…”_
+
+**If you are filing an issue to report a bug**, please provide:
+
+ 1. **A clear description of the bug and related expectations.** Consider using the following example template for reporting a bug:
+
+ ```markdown
+ The `paper-foo` element causes the page to turn pink when clicked.
+
+ ## Expected outcome
+
+ The page stays the same color.
+
+ ## Actual outcome
+
+ The page turns pink.
+
+ ## Steps to reproduce
+
+ 1. Put a `paper-foo` element in the page.
+ 2. Open the page in a web browser.
+ 3. Click the `paper-foo` element.
+ ```
+
+ 2. **A reduced test case that demonstrates the problem.** If possible, please include the test case as a JSBin. Start with this template to easily import and use relevant Polymer Elements: [https://jsbin.com/cagaye/edit?html,output](https://jsbin.com/cagaye/edit?html,output).
+
+ 3. **A list of browsers where the problem occurs.** This can be skipped if the problem is the same across all browsers.
+
+### Submitting Pull Requests
+
+**Before creating a pull request**, please ensure that an issue exists for the corresponding change in the pull request that you intend to make. **If an issue does not exist, please create one per the guidelines above**. The goal is to discuss the design and necessity of the proposed change with Polymer authors and community before diving into a pull request.
+
+When submitting pull requests, please provide:
+
+ 1. **A reference to the corresponding issue** or issues that will be closed by the pull request. Please refer to these issues in the pull request description using the following syntax:
+
+ ```markdown
+ (For a single issue)
+ Fixes #20
+
+ (For multiple issues)
+ Fixes #32, fixes #40
+ ```
+
+ 2. **A succinct description of the design** used to fix any related issues. For example:
+
+ ```markdown
+ This fixes #20 by removing styles that leaked which would cause the page to turn pink whenever `paper-foo` is clicked.
+ ```
+
+ 3. **At least one test for each bug fixed or feature added** as part of the pull request. Pull requests that fix bugs or add features without accompanying tests will not be considered.
+
+If a proposed change contains multiple commits, please [squash commits](https://www.google.com/url?q=http://blog.steveklabnik.com/posts/2012-11-08-how-to-squash-commits-in-a-github-pull-request) to as few as is necessary to succinctly express the change. A Polymer author can help you squash commits, so don’t be afraid to ask us if you need help with that!

+# Polymer Elements
+## Guide for Contributors
+
+Polymer Elements are built in the open, and the Polymer authors eagerly encourage any and all forms of community contribution. When contributing, please follow these guidelines:
+
+### Filing Issues
+
+**If you are filing an issue to request a feature**, please provide a clear description of the feature. It can be helpful to describe answers to the following questions:
+
+ 1. **Who will use the feature?** _“As someone filling out a form…”_
+ 2. **When will they use the feature?** _“When I enter an invalid value…”_
+ 3. **What is the user’s goal?** _“I want to be visually notified that the value needs to be corrected…”_
+
+**If you are filing an issue to report a bug**, please provide:
+
+ 1. **A clear description of the bug and related expectations.** Consider using the following example template for reporting a bug:
+
+ ```markdown
+ The `paper-foo` element causes the page to turn pink when clicked.
+
+ ## Expected outcome
+
+ The page stays the same color.
+
+ ## Actual outcome
+
+ The page turns pink.
+
+ ## Steps to reproduce
+
+ 1. Put a `paper-foo` element in the page.
+ 2. Open the page in a web browser.
+ 3. Click the `paper-foo` element.
+ ```
+
+ 2. **A reduced test case that demonstrates the problem.** If possible, please include the test case as a JSBin. Start with this template to easily import and use relevant Polymer Elements: [https://jsbin.com/cagaye/edit?html,output](https://jsbin.com/cagaye/edit?html,output).
+
+ 3. **A list of browsers where the problem occurs.** This can be skipped if the problem is the same across all browsers.
+
+### Submitting Pull Requests
+
+**Before creating a pull request**, please ensure that an issue exists for the corresponding change in the pull request that you intend to make. **If an issue does not exist, please create one per the guidelines above**. The goal is to discuss the design and necessity of the proposed change with Polymer authors and community before diving into a pull request.
+
+When submitting pull requests, please provide:
+
+ 1. **A reference to the corresponding issue** or issues that will be closed by the pull request. Please refer to these issues in the pull request description using the following syntax:
+
+ ```markdown
+ (For a single issue)
+ Fixes #20
+
+ (For multiple issues)
+ Fixes #32, fixes #40
+ ```
+
+ 2. **A succinct description of the design** used to fix any related issues. For example:
+
+ ```markdown
+ This fixes #20 by removing styles that leaked which would cause the page to turn pink whenever `paper-foo` is clicked.
+ ```
+
+ 3. **At least one test for each bug fixed or feature added** as part of the pull request. Pull requests that fix bugs or add features without accompanying tests will not be considered.
+
+If a proposed change contains multiple commits, please [squash commits](https://www.google.com/url?q=http://blog.steveklabnik.com/posts/2012-11-08-how-to-squash-commits-in-a-github-pull-request) to as few as is necessary to succinctly express the change. A Polymer author can help you squash commits, so don’t be afraid to ask us if you need help with that!

+##Polymer.IronCheckedElementBehavior
+
+Use `Polymer.IronCheckedElementBehavior` to implement a custom element
+that has a `checked` property, which can be used for validation if the
+element is also `required`. Element instances implementing this behavior
+will also be registered for use in an `iron-form` element.

+# Polymer Elements
+## Guide for Contributors
+
+Polymer Elements are built in the open, and the Polymer authors eagerly encourage any and all forms of community contribution. When contributing, please follow these guidelines:
+
+### Filing Issues
+
+**If you are filing an issue to request a feature**, please provide a clear description of the feature. It can be helpful to describe answers to the following questions:
+
+ 1. **Who will use the feature?** _“As someone filling out a form…”_
+ 2. **When will they use the feature?** _“When I enter an invalid value…”_
+ 3. **What is the user’s goal?** _“I want to be visually notified that the value needs to be corrected…”_
+
+**If you are filing an issue to report a bug**, please provide:
+
+ 1. **A clear description of the bug and related expectations.** Consider using the following example template for reporting a bug:
+
+ ```markdown
+ The `paper-foo` element causes the page to turn pink when clicked.
+
+ ## Expected outcome
+
+ The page stays the same color.
+
+ ## Actual outcome
+
+ The page turns pink.
+
+ ## Steps to reproduce
+
+ 1. Put a `paper-foo` element in the page.
+ 2. Open the page in a web browser.
+ 3. Click the `paper-foo` element.
+ ```
+
+ 2. **A reduced test case that demonstrates the problem.** If possible, please include the test case as a JSBin. Start with this template to easily import and use relevant Polymer Elements: [https://jsbin.com/cagaye/edit?html,output](https://jsbin.com/cagaye/edit?html,output).
+
+ 3. **A list of browsers where the problem occurs.** This can be skipped if the problem is the same across all browsers.
+
+### Submitting Pull Requests
+
+**Before creating a pull request**, please ensure that an issue exists for the corresponding change in the pull request that you intend to make. **If an issue does not exist, please create one per the guidelines above**. The goal is to discuss the design and necessity of the proposed change with Polymer authors and community before diving into a pull request.
+
+When submitting pull requests, please provide:
+
+ 1. **A reference to the corresponding issue** or issues that will be closed by the pull request. Please refer to these issues in the pull request description using the following syntax:
+
+ ```markdown
+ (For a single issue)
+ Fixes #20
+
+ (For multiple issues)
+ Fixes #32, fixes #40
+ ```
+
+ 2. **A succinct description of the design** used to fix any related issues. For example:
+
+ ```markdown
+ This fixes #20 by removing styles that leaked which would cause the page to turn pink whenever `paper-foo` is clicked.
+ ```
+
+ 3. **At least one test for each bug fixed or feature added** as part of the pull request. Pull requests that fix bugs or add features without accompanying tests will not be considered.
+
+If a proposed change contains multiple commits, please [squash commits](https://www.google.com/url?q=http://blog.steveklabnik.com/posts/2012-11-08-how-to-squash-commits-in-a-github-pull-request) to as few as is necessary to succinctly express the change. A Polymer author can help you squash commits, so don’t be afraid to ask us if you need help with that!

+
+_[Demo and API docs](https://elements.polymer-project.org/elements/iron-collapse)_
+
+
+##&lt;iron-collapse&gt;
+
+`iron-collapse` creates a collapsible block of content.  By default, the content
+will be collapsed.  Use `opened` or `toggle()` to show/hide the content.
+
+```html
+<button on-click="toggle">toggle collapse</button>
+
+<iron-collapse id="collapse">
+  <div>Content goes here...</div>
+</iron-collapse>
+
+...
+
+toggle: function() {
+  this.$.collapse.toggle();
+}
+```
+
+`iron-collapse` adjusts the max-height/max-width of the collapsible element to show/hide
+the content.  So avoid putting padding/margin/border on the collapsible directly,
+and instead put a div inside and style that.
+
+```html
+<style>
+  .collapse-content {
+    padding: 15px;
+    border: 1px solid #dedede;
+  }
+</style>
+
+<iron-collapse>
+  <div class="collapse-content">
+    <div>Content goes here...</div>
+  </div>
+</iron-collapse>
+```
+
+### Styling
+
+The following custom properties and mixins are available for styling:
+
+| Custom property | Description | Default |
+| --- | --- | --- |
+| `--iron-collapse-transition-duration` | Animation transition duration | `300ms` |

+`iron-collapse` creates a collapsible block of content.  By default, the content
+will be collapsed.  Use `opened` or `toggle()` to show/hide the content.
+
+    <button on-click="toggle">toggle collapse</button>

+`iron-collapse` adjusts the max-height/max-width of the collapsible element to show/hide
+the content.  So avoid putting padding/margin/border on the collapsible directly,
+and instead put a div inside and style that.
+
+    <style>
+      .collapse-content {
+        padding: 15px;

+# Polymer Elements
+## Guide for Contributors
+
+Polymer Elements are built in the open, and the Polymer authors eagerly encourage any and all forms of community contribution. When contributing, please follow these guidelines:
+
+### Filing Issues
+
+**If you are filing an issue to request a feature**, please provide a clear description of the feature. It can be helpful to describe answers to the following questions:
+
+ 1. **Who will use the feature?** _“As someone filling out a form…”_
+ 2. **When will they use the feature?** _“When I enter an invalid value…”_
+ 3. **What is the user’s goal?** _“I want to be visually notified that the value needs to be corrected…”_
+
+**If you are filing an issue to report a bug**, please provide:
+
+ 1. **A clear description of the bug and related expectations.** Consider using the following example template for reporting a bug:
+
+ ```markdown
+ The `paper-foo` element causes the page to turn pink when clicked.
+
+ ## Expected outcome
+
+ The page stays the same color.
+
+ ## Actual outcome
+
+ The page turns pink.
+
+ ## Steps to reproduce
+
+ 1. Put a `paper-foo` element in the page.
+ 2. Open the page in a web browser.
+ 3. Click the `paper-foo` element.
+ ```
+
+ 2. **A reduced test case that demonstrates the problem.** If possible, please include the test case as a JSBin. Start with this template to easily import and use relevant Polymer Elements: [https://jsbin.com/cagaye/edit?html,output](https://jsbin.com/cagaye/edit?html,output).
+
+ 3. **A list of browsers where the problem occurs.** This can be skipped if the problem is the same across all browsers.
+
+### Submitting Pull Requests
+
+**Before creating a pull request**, please ensure that an issue exists for the corresponding change in the pull request that you intend to make. **If an issue does not exist, please create one per the guidelines above**. The goal is to discuss the design and necessity of the proposed change with Polymer authors and community before diving into a pull request.
+
+When submitting pull requests, please provide:
+
+ 1. **A reference to the corresponding issue** or issues that will be closed by the pull request. Please refer to these issues in the pull request description using the following syntax:
+
+ ```markdown
+ (For a single issue)
+ Fixes #20
+
+ (For multiple issues)
+ Fixes #32, fixes #40
+ ```
+
+ 2. **A succinct description of the design** used to fix any related issues. For example:
+
+ ```markdown
+ This fixes #20 by removing styles that leaked which would cause the page to turn pink whenever `paper-foo` is clicked.
+ ```
+
+ 3. **At least one test for each bug fixed or feature added** as part of the pull request. Pull requests that fix bugs or add features without accompanying tests will not be considered.
+
+If a proposed change contains multiple commits, please [squash commits](https://www.google.com/url?q=http://blog.steveklabnik.com/posts/2012-11-08-how-to-squash-commits-in-a-github-pull-request) to as few as is necessary to succinctly express the change. A Polymer author can help you squash commits, so don’t be afraid to ask us if you need help with that!

+
+_[Demo and API docs](https://elements.polymer-project.org/elements/iron-dropdown)_
+
+
+##&lt;iron-dropdown&gt;
+
+`<iron-dropdown>` is a generalized element that is useful when you have
+hidden content (`.dropdown-content`) that is revealed due to some change in
+state that should cause it to do so.
+
+Note that this is a low-level element intended to be used as part of other
+composite elements that cause dropdowns to be revealed.
+
+Examples of elements that might be implemented using an `iron-dropdown`
+include comboboxes, menubuttons, selects. The list goes on.
+
+The `<iron-dropdown>` element exposes attributes that allow the position
+of the `.dropdown-content` relative to the `.dropdown-trigger` to be
+configured.
+
+```html
+<iron-dropdown horizontal-align="right" vertical-align="top">
+  <div class="dropdown-content">Hello!</div>
+</iron-dropdown>
+```
+
+In the above example, the `<div>` with class `.dropdown-content` will be
+hidden until the dropdown element has `opened` set to true, or when the `open`
+method is called on the element.

+`<iron-dropdown>` is a generalized element that is useful when you have
+hidden content (`.dropdown-content`) that is revealed due to some change in
+state that should cause it to do so.
+
+Note that this is a low-level element intended to be used as part of other
+composite elements that cause dropdowns to be revealed.
+
+Examples of elements that might be implemented using an `iron-dropdown`
+include comboboxes, menubuttons, selects. The list goes on.
+
+The `<iron-dropdown>` element exposes attributes that allow the position
+of the `.dropdown-content` relative to the `.dropdown-trigger` to be
+configured.
+
+    <iron-dropdown horizontal-align="right" vertical-align="top">
+      <div class="dropdown-content">Hello!</div>
+    </iron-dropdown>
+
+In the above example, the `<div>` with class `.dropdown-content` will be
+hidden until the dropdown element has `opened` set to true, or when the `open`
+method is called on the element.

+## Guide for Contributors
+
+Polymer Elements are built in the open, and the Polymer authors eagerly encourage any and all forms of community contribution. When contributing, please follow these guidelines:
+
+### Filing Issues
+
+**If you are filing an issue to request a feature**, please provide a clear description of the feature. It can be helpful to describe answers to the following questions:
+
+ 1. **Who will use the feature?** _“As someone filling out a form…”_
+ 2. **When will they use the feature?** _“When I enter an invalid value…”_
+ 3. **What is the user’s goal?** _“I want to be visually notified that the value needs to be corrected…”_
+
+**If you are filing an issue to report a bug**, please provide:
+
+ 1. **A clear description of the bug and related expectations.** Consider using the following example template for reporting a bug:
+
+ ```markdown
+ The `paper-foo` element causes the page to turn pink when clicked.
+
+ ## Expected outcome
+
+ The page stays the same color.
+
+ ## Actual outcome
+
+ The page turns pink.
+
+ ## Steps to reproduce
+
+ 1. Put a `paper-foo` element in the page.
+ 2. Open the page in a web browser.
+ 3. Click the `paper-foo` element.
+ ```
+
+ 2. **A reduced test case that demonstrates the problem.** If possible, please include the test case as a JSBin. Start with this template to easily import and use relevant Polymer Elements: [https://jsbin.com/cagaye/edit?html,output](https://jsbin.com/cagaye/edit?html,output).
+
+ 3. **A list of browsers where the problem occurs.** This can be skipped if the problem is the same across all browsers.
+
+### Submitting Pull Requests
+
+**Before creating a pull request**, please ensure that an issue exists for the corresponding change in the pull request that you intend to make. **If an issue does not exist, please create one per the guidelines above**. The goal is to discuss the design and necessity of the proposed change with Polymer authors and community before diving into a pull request.
+
+When submitting pull requests, please provide:
+
+ 1. **A reference to the corresponding issue** or issues that will be closed by the pull request. Please refer to these issues in the pull request description using the following syntax:

+##Polymer.IronFitBehavior
+
+`Polymer.IronFitBehavior` fits an element in another element using `max-height` and `max-width`, and
+optionally centers it in the window or another element.
+
+The element will only be sized and/or positioned if it has not already been sized and/or positioned
+by CSS.
+
+| CSS properties | Action |
+| --- | --- |
+| `position` set | Element is not centered horizontally or vertically |
+| `top` or `bottom` set | Element is not vertically centered |
+| `left` or `right` set | Element is not horizontally centered |
+| `max-height` set | Element respects `max-height` |
+| `max-width` set | Element respects `max-width` |
+
+`Polymer.IronFitBehavior` can position an element into another element using
+`verticalAlign` and `horizontalAlign`. This will override the element's css position.
+
+```html
+  <div class="container">
+    <iron-fit-impl vertical-align="top" horizontal-align="auto">
+      Positioned into the container
+    </iron-fit-impl>
+  </div>
+```
+
+Use `noOverlap` to position the element around another element without overlapping it.
+
+```html
+  <div class="container">
+    <iron-fit-impl no-overlap vertical-align="auto" horizontal-align="auto">
+      Positioned around the container
+    </iron-fit-impl>
+  </div>
+```

+# Polymer Elements
+## Guide for Contributors
+
+Polymer Elements are built in the open, and the Polymer authors eagerly encourage any and all forms of community contribution. When contributing, please follow these guidelines:
+
+### Filing Issues
+
+**If you are filing an issue to request a feature**, please provide a clear description of the feature. It can be helpful to describe answers to the following questions:
+
+ 1. **Who will use the feature?** _“As someone filling out a form…”_
+ 2. **When will they use the feature?** _“When I enter an invalid value…”_
+ 3. **What is the user’s goal?** _“I want to be visually notified that the value needs to be corrected…”_
+
+**If you are filing an issue to report a bug**, please provide:
+
+ 1. **A clear description of the bug and related expectations.** Consider using the following example template for reporting a bug:
+
+ ```markdown
+ The `paper-foo` element causes the page to turn pink when clicked.
+
+ ## Expected outcome
+
+ The page stays the same color.
+
+ ## Actual outcome
+
+ The page turns pink.
+
+ ## Steps to reproduce
+
+ 1. Put a `paper-foo` element in the page.
+ 2. Open the page in a web browser.
+ 3. Click the `paper-foo` element.
+ ```
+
+ 2. **A reduced test case that demonstrates the problem.** If possible, please include the test case as a JSBin. Start with this template to easily import and use relevant Polymer Elements: [https://jsbin.com/cagaye/edit?html,output](https://jsbin.com/cagaye/edit?html,output).
+
+ 3. **A list of browsers where the problem occurs.** This can be skipped if the problem is the same across all browsers.
+
+### Submitting Pull Requests
+
+**Before creating a pull request**, please ensure that an issue exists for the corresponding change in the pull request that you intend to make. **If an issue does not exist, please create one per the guidelines above**. The goal is to discuss the design and necessity of the proposed change with Polymer authors and community before diving into a pull request.
+
+When submitting pull requests, please provide:
+
+ 1. **A reference to the corresponding issue** or issues that will be closed by the pull request. Please refer to these issues in the pull request description using the following syntax:
+
+ ```markdown
+ (For a single issue)
+ Fixes #20
+
+ (For multiple issues)
+ Fixes #32, fixes #40
+ ```
+
+ 2. **A succinct description of the design** used to fix any related issues. For example:
+
+ ```markdown
+ This fixes #20 by removing styles that leaked which would cause the page to turn pink whenever `paper-foo` is clicked.
+ ```
+
+ 3. **At least one test for each bug fixed or feature added** as part of the pull request. Pull requests that fix bugs or add features without accompanying tests will not be considered.
+
+If a proposed change contains multiple commits, please [squash commits](https://www.google.com/url?q=http://blog.steveklabnik.com/posts/2012-11-08-how-to-squash-commits-in-a-github-pull-request) to as few as is necessary to succinctly express the change. A Polymer author can help you squash commits, so don’t be afraid to ask us if you need help with that!

+## Overview
+
+The `iron-flex-layout` component provides simple ways to use [CSS flexible box layout](https://developer.mozilla.org/en-US/docs/Web/Guide/CSS/Flexible_boxes), also known as _flexbox_. This component provides two different ways to use flexbox:
+
+*   Layout classes. The layout class stylesheet provides a simple set of class-based flexbox rules. Layout classes
+    let you specify layout properties directly in markup.
+
+*   Custom CSS mixins.  The mixin stylesheet includes custom CSS mixins that can be applied
+    inside a CSS rule using the `@apply` function.
+
+Using the classes or CSS mixins is largely a matter of preference. The following sections discuss
+how to use the each of the stylesheets.
+
+> <b>Note:</b> Before using either of these stylesheets, it's helpful to be familiar with the basics
+of flexbox layout. Chris Coyier's [A Complete Guide to Flexbox](https://css-tricks.com/snippets/css/a-guide-to-flexbox/) is a
+good primer.</aside>
+
+### Using layout classes
+
+To use layout classes import the `iron-flex-layout-classes` file. You
+must do this in any element that uses any of the `iron-flex-layout` styles.
+```html
+<link rel="import" href="bower_components/iron-flex-layout/iron-flex-layout-classes.html">
+```
+
+Then include the module(s) that you need:
+```html
+<!-- include classes in the main document -->
+<style is="custom-style" include="iron-flex iron-flex-alignment">
+```
+
+or:
+```html
+<!-- import classes in an element -->
+<style include="iron-flex iron-flex-alignment">
+```
+
+Then simply apply the classes to any element.
+```html
+<div class="layout horizontal wrap">
+```
+
+Many of the layout rules involve combinations of multiple classes (such as `layout horizontal wrap` above),
+and will need a combination of modules.
+The order in which the classes are specified doesn't matter, so `layout horizontal` and `horizontal layout`
+are equivalent.
+
+There are 5 modules available:
+- `iron-flex`. Basic flex layouts.
+- `iron-flex-reverse`. Reverse flexbox layouts.
+- `iron-flex-alignment`.  Main axis, cross axis and self alignment.
+- `iron-flex-factors`. All the available flex factors.
+- `iron-positioning`. Generic, non-flexbox positioning helpers.
+
+**Example: using classes in the main document**
+```html
+<head>
+
+  ...
+
+  <link rel="import" href="bower_components/iron-flex-layout/iron-flex-layout-classes.html">
+
+  ...
+
+  <!-- main document -- include the module you need in a custom-style element -->
+  <style is="custom-style" include="iron-flex"></style>
+
+</head>
+<body>
+
+  <div class="layout horizontal">
+    <div>One</div>
+    <div>Two</div>
+    <div>Three</div>
+  </div>
+
+</body>
+```
+**Example: using classes in a Polymer element**
+```html
+<link rel="import" href="bower_components/iron-flex-layout/iron-flex-layout-classes.html">
+
+  ...
+
+<dom-module id="mixin-demo">
+
+  <!-- inside an element -- include the module you need in a standard style element -->
+  <style include="iron-flex"></style>
+
+  <template>
+    <div class="layout horizontal">
+      <div>One</div>
+      <div>Two</div>
+      <div>Three</div>
+    </div>
+  </template>
+
+  <script>
+    Polymer({ is: 'mixin-demo' });
+  </script>
+
+</dom-module>
+```
+
+It's important to note that unlike the previous layout class stylesheets
+(found in `/classes/iron-flex-layout.html`), the new version does not use the `/deep/`
+combinator: it does not work across local DOM boundaries,
+and the modules must be imported into each scope where they're used.
+
+### Using layout mixins
+
+Custom mixins can be applied inside a Polymer
+custom element's stylesheet, **or** inside a `custom-style` stylesheet to apply styles to the
+main document. (They cannot be applied in the main document without a `custom-style` stylesheet.)
+
+**Example: using mixins in the main document**
+```html
+<head>
+
+  ...
+
+  <link rel="import" href="bower_components/iron-flex-layout/iron-flex-layout.html">
+
+  ...
+
+  <!-- main document -- apply mixins in a custom-style element -->
+  <style is="custom-style">
+    .container {
+      @apply(--layout-horizontal);
+      @apply(--layout-wrap);
+    }
+  </style>
+
+</head>
+<body>
+
+  <div class="container">
+    <div>One</div>
+    <div>Two</div>
+    <div>Three</div>
+  </div>
+
+</body>
+```
+**Example: using mixins in a Polymer element**
+```html
+<link rel="import" href="bower_components/iron-flex-layout/iron-flex-layout.html">
+
+  ...
+
+<dom-module id="mixin-demo">
+
+  <!-- inside an element -- apply mixins in a standard style element -->
+  <style>
+    .container {
+      @apply(--layout-horizontal);
+      @apply(--layout-wrap);
+    }
+  </style>
+
+  <template>
+    <div class="container">
+      <div>One</div>
+      <div>Two</div>
+      <div>Three</div>
+    </div>
+  </template>
+
+  <script>
+    Polymer({ is: 'mixin-demo' });
+  </script>
+
+</dom-module>
+```
+
+In general the mixins require a little more code to use, but they can be preferable if you
+don't want to use the classes, or if you want to switch layouts based on a media query.
+
+Custom CSS properties and mixins are features provided by the Polymer library.
+See [Cross-scope styling](https://www.polymer-project.org/1.0/docs/devguide/styling.html#xscope-styling)
+in the Polymer developer guide.
+
+## Horizontal and vertical layout
+
+Create a flex container that lays out its children vertically or horizontally.
+
+Class | Mixin | Result
+:-|:-|:-
+<code>layout horizontal</code>| <code>--layout-horizontal</code> | Horizontal layout container.
+<code>layout vertical</code> | <code>--layout-vertical</code> | Vertical layout container.
+
+The classes listed here are included in the `iron-flex` module of the `iron-flex-layout-classes` file.
+
+**Example: classes**
+```html
+<div class="layout horizontal">
+  <div>One</div>
+  <div>Two</div>
+  <div>Three</div>
+</div>
+```

+  <div>Two</div>

+</div>
+```
+
+### Flexible children
+
+Children of a flex container can use flex to control their own sizing.
+
+Class | Mixin | Result
+:-|:-|:-
+<code>flex</code>| <code>--layout-flex</code> | Expand the child to fill available space in the main axis.
+<code>flex-<var>ratio</var></code>| <code>--layout-flex-<var>ratio</var></code> | Assign a flex ratio of 1 to 12.
+<code>flex-none</code>| <code>--layout-flex-none</code> | Don't flex the child.
+<code>flex-auto</code>| <code>--layout-flex-auto</code> | Sets flex `flex-basis` to `auto` and `flex-grow` and `flex-shrink` to 1.
+
+The classes listed here are included in the `iron-flex` module of the `iron-flex-layout-classes` file.
+
+**Example: classes**
+```html
+<div class="horizontal layout">
+  <div>Alpha</div>
+  <div class="flex">Beta (flex)</div>
+  <div>Gamma</div>
+</div>
+```

+  <div class="flexchild">Beta (flex)</div>

+```
+
+#### Flexible children in vertical layouts
+
+The same rules can be used for children in vertical layouts.
+
+**Example: classes**
+```html
+<div class="vertical layout" style="height:250px">
+  <div>Alpha</div>
+  <div class="flex">Beta (flex)</div>
+  <div>Gamma</div>
+</div>

+            background-color: #ccc;
+            padding: 4px;
+          }
+
+          .container div, .layout div {
+            background-color: white;
+            padding: 12px;
+            margin: 4px;

+  </template>
+</custom-element-demo>
+```
+-->
+```html
+<style is="custom-style">
+  .container {
+    @apply(--layout-vertical);
+  }
+  .flexchild {
+    @apply(--layout-flex);
+  }
+</style>
+
+<div class="container" style="height: 250px">
+  <div>One</div>
+  <div class="flexchild">Two</div>
+  <div>Three</div>
+</div>
+```
+
+> **Note**: for vertical layouts, the container needs to have a height for the
+children to flex correctly.
+
+#### Flex ratios
+
+Children elements can be told to take up more space by including a "flex ratio"
+from 1 to 12. This is equivalent to specifying the CSS `flex-grow` property.
+
+For example, the following examples make "Gamma" 2x larger than "Beta" and "Alpha" 3x larger, use
+`flex-2` and `flex-3`, respectively.
+
+The classes listed here are included in the `iron-flex-factors` module of the `iron-flex-layout-classes` file.
+
+**Example: classes**
+```html
+<div class="horizontal layout demo">
+  <div class="flex-3">Alpha</div>
+  <div class="flex">Beta</div>
+  <div class="flex-2">Gamma</div>
+</div>
+```

+
+### Cross-axis alignment
+
+By default, children stretch to fit the cross-axis (e.g. _vertical_ stretching in a _horizontal_ layout).

+### Justification
+
+Justifying aligns contents along the **main axis**.  Justify the layout
+by specifying  one of the following.
+
+
+Class | Mixin | Result
+:-|:-|:-
+`start-justified`| <code>--layout-start-justified</code> | Aligns contents at the start of the main axis.
+`center-justified` | <code>--layout-center-justified</code> | Centers contents along the main axis.
+`end-justified` | <code>--layout-end-justified</code> | Aligns contents to the end of the main axis.
+`justified` | <code>--layout-justified</code> | Aligns contents with equal spaces between children.
+`around-justified` | <code>--layout-around-justified</code> | Aligns contents with equal spaces arround children.
+
+The classes listed here are included in the `iron-flex-alignment` module of the `iron-flex-layout-classes` file.

+Alignment can also be set per-child (instead of using the layout container's rules).
+

+`self-end` | <code>--layout-self-end</code> | Aligns the child at the end of the cross-axis.
+`self-stretch` | <code>--layout-self-stretch</code> | Stretches the child to fit the cross-axis.

+  <div>Beta</div>
+  <div>Gamma</div>
+  <div>Delta</div>
+</div>
+```
+
+## Reversed layouts
+
+Layout direction can be mirrored using the following rules:
+
+Class | Mixin | Result
+:-|:-|:-
+<code>layout horizontal-reverse</code>| <code>--layout-horizontal-reverse</code> | Horizontal layout with children laid out in reverse order (last-to-first).
+<code>layout vertical-reverse</code> | <code>--layout-vertical-reverse</code> | Vertical layout with children laid out in reverse order.
+<code>layout wrap-reverse</code> | <code>--layout-wrap-reverse</code> | Wrap layout with wrapped rows placed in the reverse order (for example, in a vertical layout, the second row is placed above the first row, instead of below).
+
+The classes listed here are included in the `iron-flex-reverse` module of the `iron-flex-layout-classes` file.
+
+**Example: mixins**
+<!--
+```
+<custom-element-demo>

+    <script src="../webcomponentsjs/webcomponents-lite.min.js"></script>

+    </dom-module>
+    <demo-element></demo-element>
+  </template>
+</custom-element-demo>
+```
+-->
+```html
+<style is="custom-style">
+  .container {
+    @apply(--layout-horizontal-reverse);
+  }
+</style>
+
+<div class="container">
+  <div>Alpha</div>
+  <div>Beta</div>
+  <div>Gamma</div>
+  <div>Delta</div>
+</div>
+```
+
+## Full bleed &lt;body>
+
+It's common to want the entire `<body>` to fit to the viewport. By themselves, Polymer's layout features on
+`<body>` don't achieve the result. You can make `<body>` take up the entire viewport by adding the `fullbleed` class:
+
+```html
+<body class="fullbleed vertical layout">
+  <div class="flex">Fitting a fullbleed body.</div>
+</body>
+```
+
+This removes its margins and maximizes its height to the viewport. There is no equivalent mixin, but the same result can
+be achieved in CSS very simply:
+```css
+body {
+  margin: 0;
+  height: 100vh;
+}
+```
+
+This class is included in the `iron-positioning` module of the `iron-flex-layout-classes` file.
+
+Note that the `fullbleed` class **only works on the `<body>` tag.** This is the only rule in the
+stylesheet that is scoped to a particular tag.
+
+
+## General purpose rules
+
+Polymer also includes other general purpose rules for basic positioning:
+
+Class | Mixin | Result
+:-|:-|:-
+`block`| `--layout-block` | Assigns `display: block`
+`invisible` | `--layout-invisible` | Assigns `visibility: hidden`
+`relative` | `--layout-relative` | Assigns `position: relative`
+`fit` | `--layout-fit` | Sets `position: absolute` and sets `top:0;right:0;bottom:0;left:0;` (aka "trbl fitting").
+
+The classes listed here are included in the `iron-positioning` module of the `iron-flex-layout-classes` file.
+
+> <b>Note:</b>When using `fit` layout, the element must have an ancestor with fixed size and `position: relative` layout
+to fit inside of.
+
+
+**Example: classes**

+## &lt;iron-flex-layout&gt;
+
+The `<iron-flex-layout>` component provides simple ways to use
+[CSS flexible box layout](https://developer.mozilla.org/en-US/docs/Web/Guide/CSS/Flexible_boxes),
+also known as flexbox. This component provides two different ways to use flexbox:
+
+1. [Layout classes](https://github.com/PolymerElements/iron-flex-layout/tree/master/iron-flex-layout-classes.html).
+The layout class stylesheet provides a simple set of class-based flexbox rules, that
+let you specify layout properties directly in markup. You must include this file
+in every element that needs to use them.
+
+Sample use:
+
+<!--

+  <div>cross axis start alignment</div>
+</div>
+```
+
+1. [Custom CSS mixins](https://github.com/PolymerElements/iron-flex-layout/blob/master/iron-flex-layout.html).
+The mixin stylesheet includes custom CSS mixins that can be applied inside a CSS rule using the `@apply` function.
+
+
+
+Please note that the old [/deep/ layout classes](https://github.com/PolymerElements/iron-flex-layout/tree/master/classes)
+are deprecated, and should not be used. To continue using layout properties
+directly in markup, please switch to using the new `dom-module`-based
+[layout classes](https://github.com/PolymerElements/iron-flex-layout/tree/master/iron-flex-layout-classes.html).
+Please note that the new version does not use `/deep/`, and therefore requires you
+to import the `dom-modules` in every element that needs to use them.
+
+A complete [guide](https://elements.polymer-project.org/guides/flex-layout) to `<iron-flex-layout>` is available.

+The `<iron-flex-layout>` component provides simple ways to use
+[CSS flexible box layout](https://developer.mozilla.org/en-US/docs/Web/Guide/CSS/Flexible_boxes),
+also known as flexbox. This component provides two different ways to use flexbox:
+
+1. [Layout classes](https://github.com/PolymerElements/iron-flex-layout/tree/master/iron-flex-layout-classes.html).
+The layout class stylesheet provides a simple set of class-based flexbox rules, that
+let you specify layout properties directly in markup. You must include this file
+in every element that needs to use them.
+
+    Sample use:
+
+    ```
+    <custom-element-demo>
+      <template>
+        <script src="../webcomponentsjs/webcomponents-lite.js"></script>
+        <next-code-block></next-code-block>
+      </template>
+    </custom-element-demo>
+    ```
+
+    ```html
+    <link rel="import" href="iron-flex-layout-classes.html">
+    <style is="custom-style" include="iron-flex iron-flex-alignment"></style>
+    <style>
+      .test { width: 100px; }
+    </style>
+    <div class="layout horizontal center-center">
+      <div class="test">horizontal layout center alignment</div>
+    </div>
+    ```
+
+2. [Custom CSS mixins](https://github.com/PolymerElements/iron-flex-layout/blob/master/iron-flex-layout.html).
+The mixin stylesheet includes custom CSS mixins that can be applied inside a CSS rule using the `@apply` function.
+
+Please note that the old [/deep/ layout classes](https://github.com/PolymerElements/iron-flex-layout/tree/master/classes)
+are deprecated, and should not be used. To continue using layout properties
+directly in markup, please switch to using the new `dom-module`-based
+[layout classes](https://github.com/PolymerElements/iron-flex-layout/tree/master/iron-flex-layout-classes.html).
+Please note that the new version does not use `/deep/`, and therefore requires you
+to import the `dom-modules` in every element that needs to use them.
+
+A complete [guide](https://elements.polymer-project.org/guides/flex-layout) to `<iron-flex-layout>` is available.

+# Polymer Elements
+## Guide for Contributors
+
+Polymer Elements are built in the open, and the Polymer authors eagerly encourage any and all forms of community contribution. When contributing, please follow these guidelines:
+
+### Filing Issues
+
+**If you are filing an issue to request a feature**, please provide a clear description of the feature. It can be helpful to describe answers to the following questions:
+
+ 1. **Who will use the feature?** _“As someone filling out a form…”_
+ 2. **When will they use the feature?** _“When I enter an invalid value…”_
+ 3. **What is the user’s goal?** _“I want to be visually notified that the value needs to be corrected…”_
+
+**If you are filing an issue to report a bug**, please provide:
+
+ 1. **A clear description of the bug and related expectations.** Consider using the following example template for reporting a bug:
+
+ ```markdown
+ The `paper-foo` element causes the page to turn pink when clicked.
+
+ ## Expected outcome
+
+ The page stays the same color.
+
+ ## Actual outcome
+
+ The page turns pink.
+
+ ## Steps to reproduce
+
+ 1. Put a `paper-foo` element in the page.
+ 2. Open the page in a web browser.
+ 3. Click the `paper-foo` element.
+ ```
+
+ 2. **A reduced test case that demonstrates the problem.** If possible, please include the test case as a JSBin. Start with this template to easily import and use relevant Polymer Elements: [https://jsbin.com/cagaye/edit?html,output](https://jsbin.com/cagaye/edit?html,output).
+
+ 3. **A list of browsers where the problem occurs.** This can be skipped if the problem is the same across all browsers.
+
+### Submitting Pull Requests
+
+**Before creating a pull request**, please ensure that an issue exists for the corresponding change in the pull request that you intend to make. **If an issue does not exist, please create one per the guidelines above**. The goal is to discuss the design and necessity of the proposed change with Polymer authors and community before diving into a pull request.
+
+When submitting pull requests, please provide:
+
+ 1. **A reference to the corresponding issue** or issues that will be closed by the pull request. Please refer to these issues in the pull request description using the following syntax:
+
+ ```markdown
+ (For a single issue)
+ Fixes #20
+
+ (For multiple issues)
+ Fixes #32, fixes #40
+ ```
+
+ 2. **A succinct description of the design** used to fix any related issues. For example:
+
+ ```markdown
+ This fixes #20 by removing styles that leaked which would cause the page to turn pink whenever `paper-foo` is clicked.
+ ```
+
+ 3. **At least one test for each bug fixed or feature added** as part of the pull request. Pull requests that fix bugs or add features without accompanying tests will not be considered.
+
+If a proposed change contains multiple commits, please [squash commits](https://www.google.com/url?q=http://blog.steveklabnik.com/posts/2012-11-08-how-to-squash-commits-in-a-github-pull-request) to as few as is necessary to succinctly express the change. A Polymer author can help you squash commits, so don’t be afraid to ask us if you need help with that!

+# Polymer Elements
+## Guide for Contributors
+
+Polymer Elements are built in the open, and the Polymer authors eagerly encourage any and all forms of community contribution. When contributing, please follow these guidelines:
+
+### Filing Issues
+
+**If you are filing an issue to request a feature**, please provide a clear description of the feature. It can be helpful to describe answers to the following questions:
+
+ 1. **Who will use the feature?** _“As someone filling out a form…”_
+ 2. **When will they use the feature?** _“When I enter an invalid value…”_
+ 3. **What is the user’s goal?** _“I want to be visually notified that the value needs to be corrected…”_
+
+**If you are filing an issue to report a bug**, please provide:
+
+ 1. **A clear description of the bug and related expectations.** Consider using the following example template for reporting a bug:
+
+ ```markdown
+ The `paper-foo` element causes the page to turn pink when clicked.
+
+ ## Expected outcome
+
+ The page stays the same color.
+
+ ## Actual outcome
+
+ The page turns pink.
+
+ ## Steps to reproduce
+
+ 1. Put a `paper-foo` element in the page.
+ 2. Open the page in a web browser.
+ 3. Click the `paper-foo` element.
+ ```
+
+ 2. **A reduced test case that demonstrates the problem.** If possible, please include the test case as a JSBin. Start with this template to easily import and use relevant Polymer Elements: [https://jsbin.com/cagaye/edit?html,output](https://jsbin.com/cagaye/edit?html,output).
+
+ 3. **A list of browsers where the problem occurs.** This can be skipped if the problem is the same across all browsers.
+
+### Submitting Pull Requests
+
+**Before creating a pull request**, please ensure that an issue exists for the corresponding change in the pull request that you intend to make. **If an issue does not exist, please create one per the guidelines above**. The goal is to discuss the design and necessity of the proposed change with Polymer authors and community before diving into a pull request.
+
+When submitting pull requests, please provide:
+
+ 1. **A reference to the corresponding issue** or issues that will be closed by the pull request. Please refer to these issues in the pull request description using the following syntax:
+
+ ```markdown
+ (For a single issue)
+ Fixes #20
+
+ (For multiple issues)
+ Fixes #32, fixes #40
+ ```
+
+ 2. **A succinct description of the design** used to fix any related issues. For example:
+
+ ```markdown
+ This fixes #20 by removing styles that leaked which would cause the page to turn pink whenever `paper-foo` is clicked.
+ ```
+
+ 3. **At least one test for each bug fixed or feature added** as part of the pull request. Pull requests that fix bugs or add features without accompanying tests will not be considered.
+
+If a proposed change contains multiple commits, please [squash commits](https://www.google.com/url?q=http://blog.steveklabnik.com/posts/2012-11-08-how-to-squash-commits-in-a-github-pull-request) to as few as is necessary to succinctly express the change. A Polymer author can help you squash commits, so don’t be afraid to ask us if you need help with that!

+
+
+## &lt;iron-form&gt;
+`<iron-form>` is a wrapper around the HTML `<form>` element, that can
+validate and submit both custom and native HTML elements.
+
+It has two modes: if `allow-redirect` is true, then after the form submission you
+will be redirected to the server response. Otherwise, if it is false, it will
+use an `iron-ajax` element to submit the form contents to the server.
+
+  Example:
+
+```html
+    <iron-form>
+      <form method="get" action="/form/handler">
+        <input type="text" name="name" value="Batman">
+        <input type="checkbox" name="donuts" checked> I like donuts<br>
+        <paper-checkbox name="cheese" value="yes" checked></paper-checkbox>
+      </form>
+    </iron-form>
+```
+
+By default, a native `<button>` element (or `input type="submit"`) will submit this form. However, if you
+want to submit it from a custom element's click handler, you need to explicitly
+call the `iron-form`'s `submit` method.
+
+  Example:
+
+```html
+    <paper-button raised onclick="submitForm()">Submit</paper-button>
+
+    function submitForm() {
+      document.getElementById('iron-form').submit();
+    }
+```

+<!--
+`<iron-form>` is a wrapper around the HTML `<form>` element, that can
+validate and submit both custom and native HTML elements. Note that this
+is a breaking change from iron-form 1.0, which was a type extension.
+
+It has two modes: if `allow-redirect` is true, then after the form submission you
+will be redirected to the server response. Otherwise, if it is false, it will
+use an `iron-ajax` element to submit the form contents to the server.
+
+  Example:
+
+    <iron-form>
+      <form method="get" action="/form/handler">
+        <input type="text" name="name" value="Batman">
+        <input type="checkbox" name="donuts" checked> I like donuts<br>
+        <paper-checkbox name="cheese" value="yes" checked></paper-checkbox>
+      </form>
+    </iron-form>
+
+By default, a native `<button>` element will submit this form. However, if you
+want to submit it from a custom element's click handler, you need to explicitly
+call the `iron-form`'s `submit` method.
+
+  Example:
+
+    <paper-button raised onclick="submitForm()">Submit</paper-button>
+
+    function submitForm() {
+      document.getElementById('iron-form').submit();
+    }
+
+If you are not using the `allow-redirect` mode, then you also have the option of
+customizing the request sent to the server. To do so, you can listen to the `iron-form-presubmit`
+event, and modify the form's [`iron-ajax`](https://elements.polymer-project.org/elements/iron-ajax)
+object. However, If you want to not use `iron-ajax` at all, you can cancel the
+event and do your own custom submission:
+
+  Example of modifying the request, but still using the build-in form submission:
+
+    form.addEventListener('iron-form-presubmit', function() {
+      this.request.method = 'put';
+      this.request.params['extraParam'] = 'someValue';
+    });
+
+  Example of bypassing the build-in form submission:
+
+    form.addEventListener('iron-form-presubmit', function(event) {
+      event.preventDefault();
+      var firebase = new Firebase(form.getAttribute('action'));
+      firebase.set(form.serializeForm());
+    });
+
+Note that if you're dynamically creating this element, it's mandatory that you
+first create the contained `<form>` element and all its children, and only then
+attach it to the `<iron-form>`:
+
+  var wrapper = document.createElement('iron-form');
+  var form = document.createElement('form');
+  var input = document.createElement('input');
+  form.appendChild(input);
+  document.body.appendChild(wrapper);
+  wrapper.appendChild(form);

+# Polymer Elements
+## Guide for Contributors
+
+Polymer Elements are built in the open, and the Polymer authors eagerly encourage any and all forms of community contribution. When contributing, please follow these guidelines:
+
+### Filing Issues
+
+**If you are filing an issue to request a feature**, please provide a clear description of the feature. It can be helpful to describe answers to the following questions:
+
+ 1. **Who will use the feature?** _“As someone filling out a form…”_
+ 2. **When will they use the feature?** _“When I enter an invalid value…”_
+ 3. **What is the user’s goal?** _“I want to be visually notified that the value needs to be corrected…”_
+
+**If you are filing an issue to report a bug**, please provide:
+
+ 1. **A clear description of the bug and related expectations.** Consider using the following example template for reporting a bug:
+
+ ```markdown
+ The `paper-foo` element causes the page to turn pink when clicked.
+
+ ## Expected outcome
+
+ The page stays the same color.
+
+ ## Actual outcome
+
+ The page turns pink.
+
+ ## Steps to reproduce
+
+ 1. Put a `paper-foo` element in the page.
+ 2. Open the page in a web browser.
+ 3. Click the `paper-foo` element.
+ ```
+
+ 2. **A reduced test case that demonstrates the problem.** If possible, please include the test case as a JSBin. Start with this template to easily import and use relevant Polymer Elements: [https://jsbin.com/cagaye/edit?html,output](https://jsbin.com/cagaye/edit?html,output).
+
+ 3. **A list of browsers where the problem occurs.** This can be skipped if the problem is the same across all browsers.
+
+### Submitting Pull Requests
+
+**Before creating a pull request**, please ensure that an issue exists for the corresponding change in the pull request that you intend to make. **If an issue does not exist, please create one per the guidelines above**. The goal is to discuss the design and necessity of the proposed change with Polymer authors and community before diving into a pull request.
+
+When submitting pull requests, please provide:
+
+ 1. **A reference to the corresponding issue** or issues that will be closed by the pull request. Please refer to these issues in the pull request description using the following syntax:
+
+ ```markdown
+ (For a single issue)
+ Fixes #20
+
+ (For multiple issues)
+ Fixes #32, fixes #40
+ ```
+
+ 2. **A succinct description of the design** used to fix any related issues. For example:
+
+ ```markdown
+ This fixes #20 by removing styles that leaked which would cause the page to turn pink whenever `paper-foo` is clicked.
+ ```
+
+ 3. **At least one test for each bug fixed or feature added** as part of the pull request. Pull requests that fix bugs or add features without accompanying tests will not be considered.
+
+If a proposed change contains multiple commits, please [squash commits](https://www.google.com/url?q=http://blog.steveklabnik.com/posts/2012-11-08-how-to-squash-commits-in-a-github-pull-request) to as few as is necessary to succinctly express the change. A Polymer author can help you squash commits, so don’t be afraid to ask us if you need help with that!

+
+The `iron-icon` element displays an icon. By default an icon renders as a 24px square.
+
+Example using src:
+
+    <iron-icon src="star.png"></iron-icon>
+
+Example setting size to 32px x 32px:
+
+    <iron-icon class="big" src="big_star.png"></iron-icon>
+
+    <style is="custom-style">
+      .big {
+        --iron-icon-height: 32px;
+        --iron-icon-width: 32px;
+      }
+    </style>
+
+The iron elements include several sets of icons.
+To use the default set of icons, import `iron-icons.html` and use the `icon` attribute to specify an icon:
+
+    <link rel="import" href="/components/iron-icons/iron-icons.html">
+
+    <iron-icon icon="menu"></iron-icon>
+
+To use a different built-in set of icons, import the specific `iron-icons/<iconset>-icons.html`, and
+specify the icon as `<iconset>:<icon>`. For example, to use a communication icon, you would
+use:
+
+    <link rel="import" href="/components/iron-icons/communication-icons.html">
+
+    <iron-icon icon="communication:email"></iron-icon>
+
+You can also create custom icon sets of bitmap or SVG icons.
+
+Example of using an icon named `cherry` from a custom iconset with the ID `fruit`:
+
+    <iron-icon icon="fruit:cherry"></iron-icon>
+
+See [iron-iconset](iron-iconset) and [iron-iconset-svg](iron-iconset-svg) for more information about
+how to create a custom iconset.
+
+See the [iron-icons demo](iron-icons?view=demo:demo/index.html) to see the icons available
+in the various iconsets.
+
+To load a subset of icons from one of the default `iron-icons` sets, you can
+use the [poly-icon](https://poly-icon.appspot.com/) tool. It allows you
+to select individual icons, and creates an iconset from them that you can
+use directly in your elements.
+
+### Styling
+
+The following custom properties are available for styling:
+
+Custom property | Description | Default
+----------------|-------------|----------
+`--iron-icon` | Mixin applied to the icon | {}
+`--iron-icon-width` | Width of the icon | `24px`
+`--iron-icon-height` | Height of the icon | `24px`
+`--iron-icon-fill-color` | Fill color of the svg icon | `currentcolor`
+`--iron-icon-stroke-color` | Stroke color of the svg icon | none

+# Polymer Elements
+## Guide for Contributors
+
+Polymer Elements are built in the open, and the Polymer authors eagerly encourage any and all forms of community contribution. When contributing, please follow these guidelines:
+
+### Filing Issues
+
+**If you are filing an issue to request a feature**, please provide a clear description of the feature. It can be helpful to describe answers to the following questions:
+
+ 1. **Who will use the feature?** _“As someone filling out a form…”_
+ 2. **When will they use the feature?** _“When I enter an invalid value…”_
+ 3. **What is the user’s goal?** _“I want to be visually notified that the value needs to be corrected…”_
+
+**If you are filing an issue to report a bug**, please provide:
+
+ 1. **A clear description of the bug and related expectations.** Consider using the following example template for reporting a bug:
+
+ ```markdown
+ The `paper-foo` element causes the page to turn pink when clicked.
+
+ ## Expected outcome
+
+ The page stays the same color.
+
+ ## Actual outcome
+
+ The page turns pink.
+
+ ## Steps to reproduce
+
+ 1. Put a `paper-foo` element in the page.
+ 2. Open the page in a web browser.
+ 3. Click the `paper-foo` element.
+ ```
+
+ 2. **A reduced test case that demonstrates the problem.** If possible, please include the test case as a JSBin. Start with this template to easily import and use relevant Polymer Elements: [https://jsbin.com/cagaye/edit?html,output](https://jsbin.com/cagaye/edit?html,output).
+
+ 3. **A list of browsers where the problem occurs.** This can be skipped if the problem is the same across all browsers.
+
+### Submitting Pull Requests
+
+**Before creating a pull request**, please ensure that an issue exists for the corresponding change in the pull request that you intend to make. **If an issue does not exist, please create one per the guidelines above**. The goal is to discuss the design and necessity of the proposed change with Polymer authors and community before diving into a pull request.
+
+When submitting pull requests, please provide:
+
+ 1. **A reference to the corresponding issue** or issues that will be closed by the pull request. Please refer to these issues in the pull request description using the following syntax:
+
+ ```markdown
+ (For a single issue)
+ Fixes #20
+
+ (For multiple issues)
+ Fixes #32, fixes #40
+ ```
+
+ 2. **A succinct description of the design** used to fix any related issues. For example:
+
+ ```markdown
+ This fixes #20 by removing styles that leaked which would cause the page to turn pink whenever `paper-foo` is clicked.
+ ```
+
+ 3. **At least one test for each bug fixed or feature added** as part of the pull request. Pull requests that fix bugs or add features without accompanying tests will not be considered.
+
+If a proposed change contains multiple commits, please [squash commits](https://www.google.com/url?q=http://blog.steveklabnik.com/posts/2012-11-08-how-to-squash-commits-in-a-github-pull-request) to as few as is necessary to succinctly express the change. A Polymer author can help you squash commits, so don’t be afraid to ask us if you need help with that!

+
+_[Demo and API docs](https://elements.polymer-project.org/elements/iron-icons)_
+
+
+##&lt;iron-icons&gt;
+
+`iron-icons` is a utility import that includes the definition for the `iron-icon` element, `iron-iconset-svg` element, as well as an import for the default icon set.
+
+The `iron-icons` directory also includes imports for additional icon sets that can be loaded into your project.
+
+Example loading icon set:
+
+```html
+<link rel="import" href="../iron-icons/maps-icons.html">
+```
+
+To use an icon from one of these sets, first prefix your `iron-icon` with the icon set name, followed by a colon, ":", and then the icon id.
+
+Example using the directions-bus icon from the maps icon set:
+
+```html
+<iron-icon icon="maps:directions-bus"></iron-icon>
+```
+
+To load a subset of icons from one of the default `iron-icons` sets, you can
+use the [poly-icon](https://poly-icon.appspot.com/) tool. It allows you
+to select individual icons, and creates an iconset from them that you can
+use directly in your elements.
+
+See [iron-icon](./iron-icon) for more information about working with icons.
+
+See [iron-iconset](./iron-iconset) and [iron-iconset-svg](./iron-iconset-svg) for more information about how to create a custom iconset.

+
+`iron-icons` is a utility import that includes the definition for the `iron-icon` element, `iron-iconset-svg` element, as well as an import for the default icon set.
+
+The `iron-icons` directory also includes imports for additional icon sets that can be loaded into your project.
+
+Example loading icon set:
+
+    <link rel="import" href="../iron-icons/maps-icons.html">
+
+To use an icon from one of these sets, first prefix your `iron-icon` with the icon set name, followed by a colon, ":", and then the icon id.
+
+Example using the directions-bus icon from the maps icon set:
+
+    <iron-icon icon="maps:directions-bus"></iron-icon>
+
+    To load a subset of icons from one of the default `iron-icons` sets, you can
+    use the [poly-icon](https://poly-icon.appspot.com/) tool. It allows you
+    to select individual icons, and creates an iconset from them that you can
+    use directly in your elements.
+
+See [iron-icon](#iron-icon) for more information about working with icons.
+
+See [iron-iconset](#iron-iconset) and [iron-iconset-svg](#iron-iconset-svg) for more information about how to create a custom iconset.

+# Polymer Elements
+## Guide for Contributors
+
+Polymer Elements are built in the open, and the Polymer authors eagerly encourage any and all forms of community contribution. When contributing, please follow these guidelines:
+
+### Filing Issues
+
+**If you are filing an issue to request a feature**, please provide a clear description of the feature. It can be helpful to describe answers to the following questions:
+
+ 1. **Who will use the feature?** _“As someone filling out a form…”_
+ 2. **When will they use the feature?** _“When I enter an invalid value…”_
+ 3. **What is the user’s goal?** _“I want to be visually notified that the value needs to be corrected…”_
+
+**If you are filing an issue to report a bug**, please provide:
+
+ 1. **A clear description of the bug and related expectations.** Consider using the following example template for reporting a bug:
+
+ ```markdown
+ The `paper-foo` element causes the page to turn pink when clicked.
+
+ ## Expected outcome
+
+ The page stays the same color.
+
+ ## Actual outcome
+
+ The page turns pink.
+
+ ## Steps to reproduce
+
+ 1. Put a `paper-foo` element in the page.
+ 2. Open the page in a web browser.
+ 3. Click the `paper-foo` element.
+ ```
+
+ 2. **A reduced test case that demonstrates the problem.** If possible, please include the test case as a JSBin. Start with this template to easily import and use relevant Polymer Elements: [https://jsbin.com/cagaye/edit?html,output](https://jsbin.com/cagaye/edit?html,output).
+
+ 3. **A list of browsers where the problem occurs.** This can be skipped if the problem is the same across all browsers.
+
+### Submitting Pull Requests
+
+**Before creating a pull request**, please ensure that an issue exists for the corresponding change in the pull request that you intend to make. **If an issue does not exist, please create one per the guidelines above**. The goal is to discuss the design and necessity of the proposed change with Polymer authors and community before diving into a pull request.
+
+When submitting pull requests, please provide:
+
+ 1. **A reference to the corresponding issue** or issues that will be closed by the pull request. Please refer to these issues in the pull request description using the following syntax:
+
+ ```markdown
+ (For a single issue)
+ Fixes #20
+
+ (For multiple issues)
+ Fixes #32, fixes #40
+ ```
+
+ 2. **A succinct description of the design** used to fix any related issues. For example:
+
+ ```markdown
+ This fixes #20 by removing styles that leaked which would cause the page to turn pink whenever `paper-foo` is clicked.
+ ```
+
+ 3. **At least one test for each bug fixed or feature added** as part of the pull request. Pull requests that fix bugs or add features without accompanying tests will not be considered.
+
+If a proposed change contains multiple commits, please [squash commits](https://www.google.com/url?q=http://blog.steveklabnik.com/posts/2012-11-08-how-to-squash-commits-in-a-github-pull-request) to as few as is necessary to succinctly express the change. A Polymer author can help you squash commits, so don’t be afraid to ask us if you need help with that!

+
+
+##&lt;iron-iconset-svg&gt;
+
+The `iron-iconset-svg` element allows users to define their own icon sets
+that contain svg icons. The svg icon elements should be children of the
+`iron-iconset-svg` element. Multiple icons should be given distinct id's.
+
+Using svg elements to create icons has a few advantages over traditional
+bitmap graphics like jpg or png. Icons that use svg are vector based so
+they are resolution independent and should look good on any device. They
+are stylable via css. Icons can be themed, colorized, and even animated.
+
+Example:
+
+```html
+<iron-iconset-svg name="my-svg-icons" size="24">
+  <svg>
+    <defs>
+      <g id="shape">
+        <rect x="12" y="0" width="12" height="24" />
+        <circle cx="12" cy="12" r="12" />
+      </g>
+    </defs>
+  </svg>
+</iron-iconset-svg>
+```
+
+This will automatically register the icon set "my-svg-icons" to the iconset
+database.  To use these icons from within another element, make a
+`iron-iconset` element and call the `byId` method
+to retrieve a given iconset. To apply a particular icon inside an
+element use the `applyIcon` method. For example:
+
+```javascript
+iconset.applyIcon(iconNode, 'car');
+```
+

+  /**
+   * The `iron-iconset-svg` element allows users to define their own icon sets
+   * that contain svg icons. The svg icon elements should be children of the
+   * `iron-iconset-svg` element. Multiple icons should be given distinct id's.
+   *
+   * Using svg elements to create icons has a few advantages over traditional
+   * bitmap graphics like jpg or png. Icons that use svg are vector based so
+   * they are resolution independent and should look good on any device. They
+   * are stylable via css. Icons can be themed, colorized, and even animated.
+   *
+   * Example:
+   *
+   *     <iron-iconset-svg name="my-svg-icons" size="24">
+   *       <svg>
+   *         <defs>
+   *           <g id="shape">
+   *             <rect x="12" y="0" width="12" height="24" />
+   *             <circle cx="12" cy="12" r="12" />
+   *           </g>
+   *         </defs>
+   *       </svg>
+   *     </iron-iconset-svg>
+   *
+   * This will automatically register the icon set "my-svg-icons" to the iconset
+   * database.  To use these icons from within another element, make a
+   * `iron-iconset` element and call the `byId` method
+   * to retrieve a given iconset. To apply a particular icon inside an
+   * element use the `applyIcon` method. For example:
+   *
+   *     iconset.applyIcon(iconNode, 'car');
+   *
+   * @element iron-iconset-svg
+   * @demo demo/index.html

+# Polymer Elements
+## Guide for Contributors
+
+Polymer Elements are built in the open, and the Polymer authors eagerly encourage any and all forms of community contribution. When contributing, please follow these guidelines:
+
+### Filing Issues
+
+**If you are filing an issue to request a feature**, please provide a clear description of the feature. It can be helpful to describe answers to the following questions:
+
+ 1. **Who will use the feature?** _“As someone filling out a form…”_
+ 2. **When will they use the feature?** _“When I enter an invalid value…”_
+ 3. **What is the user’s goal?** _“I want to be visually notified that the value needs to be corrected…”_
+
+**If you are filing an issue to report a bug**, please provide:
+
+ 1. **A clear description of the bug and related expectations.** Consider using the following example template for reporting a bug:
+
+ ```markdown
+ The `paper-foo` element causes the page to turn pink when clicked.
+
+ ## Expected outcome
+
+ The page stays the same color.
+
+ ## Actual outcome
+
+ The page turns pink.
+
+ ## Steps to reproduce
+
+ 1. Put a `paper-foo` element in the page.
+ 2. Open the page in a web browser.
+ 3. Click the `paper-foo` element.
+ ```
+
+ 2. **A reduced test case that demonstrates the problem.** If possible, please include the test case as a JSBin. Start with this template to easily import and use relevant Polymer Elements: [https://jsbin.com/cagaye/edit?html,output](https://jsbin.com/cagaye/edit?html,output).
+
+ 3. **A list of browsers where the problem occurs.** This can be skipped if the problem is the same across all browsers.
+
+### Submitting Pull Requests
+
+**Before creating a pull request**, please ensure that an issue exists for the corresponding change in the pull request that you intend to make. **If an issue does not exist, please create one per the guidelines above**. The goal is to discuss the design and necessity of the proposed change with Polymer authors and community before diving into a pull request.
+
+When submitting pull requests, please provide:
+
+ 1. **A reference to the corresponding issue** or issues that will be closed by the pull request. Please refer to these issues in the pull request description using the following syntax:
+
+ ```markdown
+ (For a single issue)
+ Fixes #20
+
+ (For multiple issues)
+ Fixes #32, fixes #40
+ ```
+
+ 2. **A succinct description of the design** used to fix any related issues. For example:
+
+ ```markdown
+ This fixes #20 by removing styles that leaked which would cause the page to turn pink whenever `paper-foo` is clicked.
+ ```
+
+ 3. **At least one test for each bug fixed or feature added** as part of the pull request. Pull requests that fix bugs or add features without accompanying tests will not be considered.
+
+If a proposed change contains multiple commits, please [squash commits](https://www.google.com/url?q=http://blog.steveklabnik.com/posts/2012-11-08-how-to-squash-commits-in-a-github-pull-request) to as few as is necessary to succinctly express the change. A Polymer author can help you squash commits, so don’t be afraid to ask us if you need help with that!

+
+_[Demo and API docs](https://elements.polymer-project.org/elements/iron-image)_
+
+
+##&lt;iron-image&gt;
+
+`iron-image` is an element for displaying an image that provides useful sizing and
+preloading options not found on the standard `<img>` tag.
+
+The `sizing` option allows the image to be either cropped (`cover`) or
+letterboxed (`contain`) to fill a fixed user-size placed on the element.
+
+The `preload` option prevents the browser from rendering the image until the
+image is fully loaded.  In the interim, either the element's CSS `background-color`
+can be be used as the placeholder, or the `placeholder` property can be
+set to a URL (preferably a data-URI, for instant rendering) for an
+placeholder image.
+
+The `fade` option (only valid when `preload` is set) will cause the placeholder
+image/color to be faded out once the image is rendered.
+
+Examples:
+
+  Basically identical to `<img src="...">` tag:
+
+```html
+<iron-image src="http://lorempixel.com/400/400"></iron-image>
+```
+
+  Will letterbox the image to fit:
+
+```html
+<iron-image style="width:400px; height:400px;" sizing="contain"
+  src="http://lorempixel.com/600/400"></iron-image>
+```
+
+  Will crop the image to fit:
+
+```html
+<iron-image style="width:400px; height:400px;" sizing="cover"
+  src="http://lorempixel.com/600/400"></iron-image>
+```
+
+  Will show light-gray background until the image loads:
+
+```html
+<iron-image style="width:400px; height:400px; background-color: lightgray;"
+  sizing="cover" preload src="http://lorempixel.com/600/400"></iron-image>
+```
+
+  Will show a base-64 encoded placeholder image until the image loads:
+
+```html
+<iron-image style="width:400px; height:400px;" placeholder="data:image/gif;base64,..."
+  sizing="cover" preload src="http://lorempixel.com/600/400"></iron-image>
+```
+
+  Will fade the light-gray background out once the image is loaded:
+
+```html
+<iron-image style="width:400px; height:400px; background-color: lightgray;"
+  sizing="cover" preload fade src="http://lorempixel.com/600/400"></iron-image>
+```
+
+| Custom property | Description | Default |
+| --- | --- | --- |
+| `--iron-image-placeholder` | Mixin applied to #placeholder | `{}` |
+| `--iron-image-width` | Sets the width of the wrapped image | `auto` |
+| `--iron-image-height` | Sets the height of the wrapped image | `auto` |

+`iron-image` is an element for displaying an image that provides useful sizing and
+preloading options not found on the standard `<img>` tag.
+
+The `sizing` option allows the image to be either cropped (`cover`) or
+letterboxed (`contain`) to fill a fixed user-size placed on the element.
+
+The `preload` option prevents the browser from rendering the image until the
+image is fully loaded.  In the interim, either the element's CSS `background-color`
+can be be used as the placeholder, or the `placeholder` property can be
+set to a URL (preferably a data-URI, for instant rendering) for an
+placeholder image.
+
+The `fade` option (only valid when `preload` is set) will cause the placeholder
+image/color to be faded out once the image is rendered.
+
+Examples:
+
+  Basically identical to `<img src="...">` tag:
+
+    <iron-image src="http://lorempixel.com/400/400"></iron-image>
+
+  Will letterbox the image to fit:
+
+    <iron-image style="width:400px; height:400px;" sizing="contain"
+      src="http://lorempixel.com/600/400"></iron-image>
+
+  Will crop the image to fit:
+
+    <iron-image style="width:400px; height:400px;" sizing="cover"
+      src="http://lorempixel.com/600/400"></iron-image>
+
+  Will show light-gray background until the image loads:
+
+    <iron-image style="width:400px; height:400px; background-color: lightgray;"
+      sizing="cover" preload src="http://lorempixel.com/600/400"></iron-image>
+
+  Will show a base-64 encoded placeholder image until the image loads:
+
+    <iron-image style="width:400px; height:400px;" placeholder="data:image/gif;base64,..."
+      sizing="cover" preload src="http://lorempixel.com/600/400"></iron-image>
+
+  Will fade the light-gray background out once the image is loaded:
+
+    <iron-image style="width:400px; height:400px; background-color: lightgray;"
+      sizing="cover" preload fade src="http://lorempixel.com/600/400"></iron-image>
+
+Custom property | Description | Default
+----------------|-------------|----------
+`--iron-image-placeholder` | Mixin applied to #placeholder | `{}`
+`--iron-image-width` | Sets the width of the wrapped image | `auto`
+`--iron-image-height` | Sets the height of the wrapped image | `auto`

+# Polymer Elements
+## Guide for Contributors
+
+Polymer Elements are built in the open, and the Polymer authors eagerly encourage any and all forms of community contribution. When contributing, please follow these guidelines:
+
+### Filing Issues
+
+**If you are filing an issue to request a feature**, please provide a clear description of the feature. It can be helpful to describe answers to the following questions:
+
+ 1. **Who will use the feature?** _“As someone filling out a form…”_
+ 2. **When will they use the feature?** _“When I enter an invalid value…”_
+ 3. **What is the user’s goal?** _“I want to be visually notified that the value needs to be corrected…”_
+
+**If you are filing an issue to report a bug**, please provide:
+
+ 1. **A clear description of the bug and related expectations.** Consider using the following example template for reporting a bug:
+
+ ```markdown
+ The `paper-foo` element causes the page to turn pink when clicked.
+
+ ## Expected outcome
+
+ The page stays the same color.
+
+ ## Actual outcome
+
+ The page turns pink.
+
+ ## Steps to reproduce
+
+ 1. Put a `paper-foo` element in the page.
+ 2. Open the page in a web browser.
+ 3. Click the `paper-foo` element.
+ ```
+
+ 2. **A reduced test case that demonstrates the problem.** If possible, please include the test case as a JSBin. Start with this template to easily import and use relevant Polymer Elements: [https://jsbin.com/cagaye/edit?html,output](https://jsbin.com/cagaye/edit?html,output).
+
+ 3. **A list of browsers where the problem occurs.** This can be skipped if the problem is the same across all browsers.
+
+### Submitting Pull Requests
+
+**Before creating a pull request**, please ensure that an issue exists for the corresponding change in the pull request that you intend to make. **If an issue does not exist, please create one per the guidelines above**. The goal is to discuss the design and necessity of the proposed change with Polymer authors and community before diving into a pull request.
+
+When submitting pull requests, please provide:
+
+ 1. **A reference to the corresponding issue** or issues that will be closed by the pull request. Please refer to these issues in the pull request description using the following syntax:
+
+ ```markdown
+ (For a single issue)
+ Fixes #20
+
+ (For multiple issues)
+ Fixes #32, fixes #40
+ ```
+
+ 2. **A succinct description of the design** used to fix any related issues. For example:
+
+ ```markdown
+ This fixes #20 by removing styles that leaked which would cause the page to turn pink whenever `paper-foo` is clicked.
+ ```
+
+ 3. **At least one test for each bug fixed or feature added** as part of the pull request. Pull requests that fix bugs or add features without accompanying tests will not be considered.
+
+If a proposed change contains multiple commits, please [squash commits](https://www.google.com/url?q=http://blog.steveklabnik.com/posts/2012-11-08-how-to-squash-commits-in-a-github-pull-request) to as few as is necessary to succinctly express the change. A Polymer author can help you squash commits, so don’t be afraid to ask us if you need help with that!

+## &lt;iron-input&gt;
+
+`<iron-input>` adds two-way binding and custom validators using `Polymer.IronValidatorBehavior`
+to `<input>`.
+
+### Two-way binding
+
+By default you can only get notified of changes to an `input`'s `value` due to user input:
+
+```html
+<input value="{{myValue::input}}">
+```
+
+`iron-input` adds the `bind-value` property that mirrors the `value` property, and can be used
+for two-way data binding. `bind-value` will notify if it is changed either by user input or by script.
+
+```html
+<input is="iron-input" bind-value="{{myValue}}">
+```
+
+### Custom validators
+
+You can use custom validators that implement `Polymer.IronValidatorBehavior` with `<iron-input>`.
+
+```html
+<input is="iron-input" validator="my-custom-validator">
+```
+
+### Stopping invalid input
+
+It may be desirable to only allow users to enter certain characters. You can use the
+`prevent-invalid-input` and `allowed-pattern` attributes together to accomplish this. This feature
+is separate from validation, and `allowed-pattern` does not affect how the input is validated.
+
+```html
+<!-- only allow characters that match [0-9] -->
+<input is="iron-input" prevent-invalid-input allowed-pattern="[0-9]">
+```
+
+

+`<iron-input>` adds two-way binding and custom validators using `Polymer.IronValidatorBehavior`
+to `<input>`.
+
+### Two-way binding
+
+By default you can only get notified of changes to an `input`'s `value` due to user input:
+
+    <input value="{{myValue::input}}">
+
+`iron-input` adds the `bind-value` property that mirrors the `value` property, and can be used
+for two-way data binding. `bind-value` will notify if it is changed either by user input or by script.
+
+    <input is="iron-input" bind-value="{{myValue}}">
+
+### Custom validators
+
+You can use custom validators that implement `Polymer.IronValidatorBehavior` with `<iron-input>`.
+
+    <input is="iron-input" validator="my-custom-validator">
+
+### Stopping invalid input
+
+It may be desirable to only allow users to enter certain characters. You can use the
+`prevent-invalid-input` and `allowed-pattern` attributes together to accomplish this. This feature
+is separate from validation, and `allowed-pattern` does not affect how the input is validated.
+
+    <!-- only allow characters that match [0-9] -->

+# Polymer Elements
+## Guide for Contributors
+
+Polymer Elements are built in the open, and the Polymer authors eagerly encourage any and all forms of community contribution. When contributing, please follow these guidelines:
+
+### Filing Issues
+
+**If you are filing an issue to request a feature**, please provide a clear description of the feature. It can be helpful to describe answers to the following questions:
+
+ 1. **Who will use the feature?** _“As someone filling out a form…”_
+ 2. **When will they use the feature?** _“When I enter an invalid value…”_
+ 3. **What is the user’s goal?** _“I want to be visually notified that the value needs to be corrected…”_
+
+**If you are filing an issue to report a bug**, please provide:
+
+ 1. **A clear description of the bug and related expectations.** Consider using the following example template for reporting a bug:
+
+ ```markdown
+ The `paper-foo` element causes the page to turn pink when clicked.
+
+ ## Expected outcome
+
+ The page stays the same color.
+
+ ## Actual outcome
+
+ The page turns pink.
+
+ ## Steps to reproduce
+
+ 1. Put a `paper-foo` element in the page.
+ 2. Open the page in a web browser.
+ 3. Click the `paper-foo` element.
+ ```
+
+ 2. **A reduced test case that demonstrates the problem.** If possible, please include the test case as a JSBin. Start with this template to easily import and use relevant Polymer Elements: [https://jsbin.com/cagaye/edit?html,output](https://jsbin.com/cagaye/edit?html,output).
+
+ 3. **A list of browsers where the problem occurs.** This can be skipped if the problem is the same across all browsers.
+
+### Submitting Pull Requests
+
+**Before creating a pull request**, please ensure that an issue exists for the corresponding change in the pull request that you intend to make. **If an issue does not exist, please create one per the guidelines above**. The goal is to discuss the design and necessity of the proposed change with Polymer authors and community before diving into a pull request.
+
+When submitting pull requests, please provide:
+
+ 1. **A reference to the corresponding issue** or issues that will be closed by the pull request. Please refer to these issues in the pull request description using the following syntax:
+
+ ```markdown
+ (For a single issue)
+ Fixes #20
+
+ (For multiple issues)
+ Fixes #32, fixes #40
+ ```
+
+ 2. **A succinct description of the design** used to fix any related issues. For example:
+
+ ```markdown
+ This fixes #20 by removing styles that leaked which would cause the page to turn pink whenever `paper-foo` is clicked.
+ ```
+
+ 3. **At least one test for each bug fixed or feature added** as part of the pull request. Pull requests that fix bugs or add features without accompanying tests will not be considered.
+
+If a proposed change contains multiple commits, please [squash commits](https://www.google.com/url?q=http://blog.steveklabnik.com/posts/2012-11-08-how-to-squash-commits-in-a-github-pull-request) to as few as is necessary to succinctly express the change. A Polymer author can help you squash commits, so don’t be afraid to ask us if you need help with that!

+
+_[Demo and API docs](https://elements.polymer-project.org/elements/iron-jsonp-library)_
+
+
+## &lt;iron-jsonp-library&gt;
+
+Loads specified jsonp library.
+
+Example:
+
+```html
+<iron-jsonp-library
+  library-url="https://apis.google.com/js/plusone.js?onload=%%callback%%"
+  notify-event="api-load"
+  library-loaded="{{loaded}}"></iron-jsonp-library>
+```
+
+Will emit 'api-load' event when loaded, and set 'loaded' to true
+
+Implemented by  Polymer.IronJsonpLibraryBehavior. Use it
+to create specific library loader elements.
+
+
+
+## Polymer.IronJsonpLibraryBehavior
+
+`Polymer.IronJsonpLibraryBehavior` loads a jsonp library.
+Multiple components can request same library, only one copy will load.
+
+Some libraries require a specific global function be defined.
+If this is the case, specify the `callbackName` property.
+
+You should use an HTML Import to load library dependencies
+when possible instead of using this element.

+# Polymer Elements
+## Guide for Contributors
+
+Polymer Elements are built in the open, and the Polymer authors eagerly encourage any and all forms of community contribution. When contributing, please follow these guidelines:
+
+### Filing Issues
+
+**If you are filing an issue to request a feature**, please provide a clear description of the feature. It can be helpful to describe answers to the following questions:
+
+ 1. **Who will use the feature?** _“As someone filling out a form…”_
+ 2. **When will they use the feature?** _“When I enter an invalid value…”_
+ 3. **What is the user’s goal?** _“I want to be visually notified that the value needs to be corrected…”_
+
+**If you are filing an issue to report a bug**, please provide:
+
+ 1. **A clear description of the bug and related expectations.** Consider using the following example template for reporting a bug:
+
+ ```markdown
+ The `paper-foo` element causes the page to turn pink when clicked.
+
+ ## Expected outcome
+
+ The page stays the same color.
+
+ ## Actual outcome
+
+ The page turns pink.
+
+ ## Steps to reproduce
+
+ 1. Put a `paper-foo` element in the page.
+ 2. Open the page in a web browser.
+ 3. Click the `paper-foo` element.
+ ```
+
+ 2. **A reduced test case that demonstrates the problem.** If possible, please include the test case as a JSBin. Start with this template to easily import and use relevant Polymer Elements: [https://jsbin.com/lebawa/edit?html,output](https://jsbin.com/lebawa/edit?html,output).
+
+ 3. **A list of browsers where the problem occurs.** This can be skipped if the problem is the same across all browsers.
+
+### Submitting Pull Requests
+
+**Before creating a pull request**, please ensure that an issue exists for the corresponding change in the pull request that you intend to make. **If an issue does not exist, please create one per the guidelines above**. The goal is to discuss the design and necessity of the proposed change with Polymer authors and community before diving into a pull request.
+
+When submitting pull requests, please provide:
+
+ 1. **A reference to the corresponding issue** or issues that will be closed by the pull request. Please refer to these issues in the pull request description using the following syntax:
+
+ ```markdown
+ (For a single issue)
+ Fixes #20
+
+ (For multiple issues)
+ Fixes #32, fixes #40
+ ```
+
+ 2. **A succinct description of the design** used to fix any related issues. For example:
+
+ ```markdown
+ This fixes #20 by removing styles that leaked which would cause the page to turn pink whenever `paper-foo` is clicked.
+ ```
+
+ 3. **At least one test for each bug fixed or feature added** as part of the pull request. Pull requests that fix bugs or add features without accompanying tests will not be considered.
+
+If a proposed change contains multiple commits, please [squash commits](https://www.google.com/url?q=http://blog.steveklabnik.com/posts/2012-11-08-how-to-squash-commits-in-a-github-pull-request) to as few as is necessary to succinctly express the change. A Polymer author can help you squash commits, so don’t be afraid to ask us if you need help with that!

+
+_[Demo and API docs](https://elements.polymer-project.org/elements/iron-location)_
+
+
+##&lt;iron-location&gt;
+
+The `iron-location` element manages binding to and from the current URL.
+
+iron-location is the first, and lowest level element in the Polymer team's
+routing system. This is a beta release of iron-location as we continue work
+on higher level elements, and as such iron-location may undergo breaking
+changes.
+
+#### Properties
+
+When the URL is: `/search?query=583#details` iron-location's properties will be:
+
+* path: `'/search'`
+* query: `'query=583'`
+* hash: `'details'`
+
+These bindings are bidirectional. Modifying them will in turn modify the URL.
+
+iron-location is only active while it is attached to the document.
+
+#### Links
+
+While iron-location is active in the document it will intercept clicks on links
+within your site, updating the URL pushing the updated URL out through the
+databinding system. iron-location only intercepts clicks with the intent to
+open in the same window, so middle mouse clicks and ctrl/cmd clicks work fine.
+
+You can customize this behavior with the `urlSpaceRegex`.
+
+#### Dwell Time
+
+iron-location protects against accidental history spamming by only adding
+entries to the user's history if the URL stays unchanged for `dwellTime`
+milliseconds.
+
+

+
+The `iron-location` element manages binding to and from the current URL.
+
+iron-location is the first, and lowest level element in the Polymer team's
+routing system. This is a beta release of iron-location as we continue work
+on higher level elements, and as such iron-location may undergo breaking
+changes.
+
+#### Properties
+
+When the URL is: `/search?query=583#details` iron-location's properties will be:
+
+  - path: `'/search'`
+  - query: `'query=583'`
+  - hash: `'details'`
+
+These bindings are bidirectional. Modifying them will in turn modify the URL.
+
+iron-location is only active while it is attached to the document.
+
+#### Links
+
+While iron-location is active in the document it will intercept clicks on links
+within your site, updating the URL pushing the updated URL out through the
+databinding system. iron-location only intercepts clicks with the intent to
+open in the same window, so middle mouse clicks and ctrl/cmd clicks work fine.
+
+You can customize this behavior with the `urlSpaceRegex`.
+
+#### Dwell Time
+
+iron-location protects against accidental history spamming by only adding
+entries to the user's history if the URL stays unchanged for `dwellTime`
+milliseconds.

+# Polymer Elements
+## Guide for Contributors
+
+Polymer Elements are built in the open, and the Polymer authors eagerly encourage any and all forms of community contribution. When contributing, please follow these guidelines:
+
+### Filing Issues
+
+**If you are filing an issue to request a feature**, please provide a clear description of the feature. It can be helpful to describe answers to the following questions:
+
+ 1. **Who will use the feature?** _“As someone filling out a form…”_
+ 2. **When will they use the feature?** _“When I enter an invalid value…”_
+ 3. **What is the user’s goal?** _“I want to be visually notified that the value needs to be corrected…”_
+
+**If you are filing an issue to report a bug**, please provide:
+
+ 1. **A clear description of the bug and related expectations.** Consider using the following example template for reporting a bug:
+
+ ```markdown
+ The `paper-foo` element causes the page to turn pink when clicked.
+
+ ## Expected outcome
+
+ The page stays the same color.
+
+ ## Actual outcome
+
+ The page turns pink.
+
+ ## Steps to reproduce
+
+ 1. Put a `paper-foo` element in the page.
+ 2. Open the page in a web browser.
+ 3. Click the `paper-foo` element.
+ ```
+
+ 2. **A reduced test case that demonstrates the problem.** If possible, please include the test case as a JSBin. Start with this template to easily import and use relevant Polymer Elements: [https://jsbin.com/cagaye/edit?html,output](https://jsbin.com/cagaye/edit?html,output).
+
+ 3. **A list of browsers where the problem occurs.** This can be skipped if the problem is the same across all browsers.
+
+### Submitting Pull Requests
+
+**Before creating a pull request**, please ensure that an issue exists for the corresponding change in the pull request that you intend to make. **If an issue does not exist, please create one per the guidelines above**. The goal is to discuss the design and necessity of the proposed change with Polymer authors and community before diving into a pull request.
+
+When submitting pull requests, please provide:
+
+ 1. **A reference to the corresponding issue** or issues that will be closed by the pull request. Please refer to these issues in the pull request description using the following syntax:
+
+ ```markdown
+ (For a single issue)
+ Fixes #20
+
+ (For multiple issues)
+ Fixes #32, fixes #40
+ ```
+
+ 2. **A succinct description of the design** used to fix any related issues. For example:
+
+ ```markdown
+ This fixes #20 by removing styles that leaked which would cause the page to turn pink whenever `paper-foo` is clicked.
+ ```
+
+ 3. **At least one test for each bug fixed or feature added** as part of the pull request. Pull requests that fix bugs or add features without accompanying tests will not be considered.
+
+If a proposed change contains multiple commits, please [squash commits](https://www.google.com/url?q=http://blog.steveklabnik.com/posts/2012-11-08-how-to-squash-commits-in-a-github-pull-request) to as few as is necessary to succinctly express the change. A Polymer author can help you squash commits, so don’t be afraid to ask us if you need help with that!

+# Polymer Elements
+## Guide for Contributors
+
+Polymer Elements are built in the open, and the Polymer authors eagerly encourage any and all forms of community contribution. When contributing, please follow these guidelines:
+
+### Filing Issues
+
+**If you are filing an issue to request a feature**, please provide a clear description of the feature. It can be helpful to describe answers to the following questions:
+
+ 1. **Who will use the feature?** _“As someone filling out a form…”_
+ 2. **When will they use the feature?** _“When I enter an invalid value…”_
+ 3. **What is the user’s goal?** _“I want to be visually notified that the value needs to be corrected…”_
+
+**If you are filing an issue to report a bug**, please provide:
+
+ 1. **A clear description of the bug and related expectations.** Consider using the following example template for reporting a bug:
+
+ ```markdown
+ The `paper-foo` element causes the page to turn pink when clicked.
+
+ ## Expected outcome
+
+ The page stays the same color.
+
+ ## Actual outcome
+
+ The page turns pink.
+
+ ## Steps to reproduce
+
+ 1. Put a `paper-foo` element in the page.
+ 2. Open the page in a web browser.
+ 3. Click the `paper-foo` element.
+ ```
+
+ 2. **A reduced test case that demonstrates the problem.** If possible, please include the test case as a JSBin. Start with this template to easily import and use relevant Polymer Elements: [https://jsbin.com/cagaye/edit?html,output](https://jsbin.com/cagaye/edit?html,output).
+
+ 3. **A list of browsers where the problem occurs.** This can be skipped if the problem is the same across all browsers.
+
+### Submitting Pull Requests
+
+**Before creating a pull request**, please ensure that an issue exists for the corresponding change in the pull request that you intend to make. **If an issue does not exist, please create one per the guidelines above**. The goal is to discuss the design and necessity of the proposed change with Polymer authors and community before diving into a pull request.
+
+When submitting pull requests, please provide:
+
+ 1. **A reference to the corresponding issue** or issues that will be closed by the pull request. Please refer to these issues in the pull request description using the following syntax:
+
+ ```markdown
+ (For a single issue)
+ Fixes #20
+
+ (For multiple issues)
+ Fixes #32, fixes #40
+ ```
+
+ 2. **A succinct description of the design** used to fix any related issues. For example:
+
+ ```markdown
+ This fixes #20 by removing styles that leaked which would cause the page to turn pink whenever `paper-foo` is clicked.
+ ```
+
+ 3. **At least one test for each bug fixed or feature added** as part of the pull request. Pull requests that fix bugs or add features without accompanying tests will not be considered.
+
+If a proposed change contains multiple commits, please [squash commits](https://www.google.com/url?q=http://blog.steveklabnik.com/posts/2012-11-08-how-to-squash-commits-in-a-github-pull-request) to as few as is necessary to succinctly express the change. A Polymer author can help you squash commits, so don’t be afraid to ask us if you need help with that!

+##&lt;iron-meta&gt;
+
+`iron-meta` is a generic element you can use for sharing information across the DOM tree.
+It uses [monostate pattern](http://c2.com/cgi/wiki?MonostatePattern) such that any
+instance of iron-meta has access to the shared
+information. You can use `iron-meta` to share whatever you want (or create an extension
+[like x-meta] for enhancements).
+
+The `iron-meta` instances containing your actual data can be loaded in an import,
+or constructed in any way you see fit. The only requirement is that you create them
+before you try to access them.
+
+Examples:
+
+If I create an instance like this:
+
+```html
+<iron-meta key="info" value="foo/bar"></iron-meta>
+```
+
+Note that value="foo/bar" is the metadata I've defined. I could define more
+attributes or use child nodes to define additional metadata.
+
+Now I can access that element (and it's metadata) from any iron-meta instance
+via the byKey method, e.g.
+
+```javascript
+meta.byKey('info');
+```
+
+Pure imperative form would be like:
+
+```javascript
+document.createElement('iron-meta').byKey('info');
+```
+
+Or, in a Polymer element, you can include a meta in your template:
+
+```html
+<iron-meta id="meta"></iron-meta>
+...
+this.$.meta.byKey('info');
+```
+

+`iron-meta` is a generic element you can use for sharing information across the DOM tree.
+It uses [monostate pattern](http://c2.com/cgi/wiki?MonostatePattern) such that any
+instance of iron-meta has access to the shared
+information. You can use `iron-meta` to share whatever you want (or create an extension
+[like x-meta] for enhancements).
+
+The `iron-meta` instances containing your actual data can be loaded in an import,
+or constructed in any way you see fit. The only requirement is that you create them
+before you try to access them.
+
+Examples:
+
+If I create an instance like this:
+
+    <iron-meta key="info" value="foo/bar"></iron-meta>
+
+Note that value="foo/bar" is the metadata I've defined. I could define more
+attributes or use child nodes to define additional metadata.
+
+Now I can access that element (and it's metadata) from any iron-meta instance
+via the byKey method, e.g.
+
+    meta.byKey('info');
+
+Pure imperative form would be like:
+
+    document.createElement('iron-meta').byKey('info');
+
+Or, in a Polymer element, you can include a meta in your template:
+
+    <iron-meta id="meta"></iron-meta>
+    ...
+    this.$.meta.byKey('info');

+# Polymer Elements
+## Guide for Contributors
+
+Polymer Elements are built in the open, and the Polymer authors eagerly encourage any and all forms of community contribution. When contributing, please follow these guidelines:
+
+### Filing Issues
+
+**If you are filing an issue to request a feature**, please provide a clear description of the feature. It can be helpful to describe answers to the following questions:
+
+ 1. **Who will use the feature?** _“As someone filling out a form…”_
+ 2. **When will they use the feature?** _“When I enter an invalid value…”_
+ 3. **What is the user’s goal?** _“I want to be visually notified that the value needs to be corrected…”_
+
+**If you are filing an issue to report a bug**, please provide:
+
+ 1. **A clear description of the bug and related expectations.** Consider using the following example template for reporting a bug:
+
+ ```markdown
+ The `paper-foo` element causes the page to turn pink when clicked.
+
+ ## Expected outcome
+
+ The page stays the same color.
+
+ ## Actual outcome
+
+ The page turns pink.
+
+ ## Steps to reproduce
+
+ 1. Put a `paper-foo` element in the page.
+ 2. Open the page in a web browser.
+ 3. Click the `paper-foo` element.
+ ```
+
+ 2. **A reduced test case that demonstrates the problem.** If possible, please include the test case as a JSBin. Start with this template to easily import and use relevant Polymer Elements: [https://jsbin.com/cagaye/edit?html,output](https://jsbin.com/cagaye/edit?html,output).
+
+ 3. **A list of browsers where the problem occurs.** This can be skipped if the problem is the same across all browsers.
+
+### Submitting Pull Requests
+
+**Before creating a pull request**, please ensure that an issue exists for the corresponding change in the pull request that you intend to make. **If an issue does not exist, please create one per the guidelines above**. The goal is to discuss the design and necessity of the proposed change with Polymer authors and community before diving into a pull request.
+
+When submitting pull requests, please provide:
+
+ 1. **A reference to the corresponding issue** or issues that will be closed by the pull request. Please refer to these issues in the pull request description using the following syntax:
+
+ ```markdown
+ (For a single issue)
+ Fixes #20
+
+ (For multiple issues)
+ Fixes #32, fixes #40
+ ```
+
+ 2. **A succinct description of the design** used to fix any related issues. For example:
+
+ ```markdown
+ This fixes #20 by removing styles that leaked which would cause the page to turn pink whenever `paper-foo` is clicked.
+ ```
+
+ 3. **At least one test for each bug fixed or feature added** as part of the pull request. Pull requests that fix bugs or add features without accompanying tests will not be considered.
+
+If a proposed change contains multiple commits, please [squash commits](https://www.google.com/url?q=http://blog.steveklabnik.com/posts/2012-11-08-how-to-squash-commits-in-a-github-pull-request) to as few as is necessary to succinctly express the change. A Polymer author can help you squash commits, so don’t be afraid to ask us if you need help with that!

+
+_[Demo and API docs](https://elements.polymer-project.org/elements/iron-overlay-behavior)_
+
+
+##Polymer.IronOverlayBehavior
+
+Use `Polymer.IronOverlayBehavior` to implement an element that can be hidden or shown, and displays
+on top of other content. It includes an optional backdrop, and can be used to implement a variety
+of UI controls including dialogs and drop downs. Multiple overlays may be displayed at once.
+
+See the [demo source code](https://github.com/PolymerElements/iron-overlay-behavior/blob/master/demo/simple-overlay.html)
+for an example.
+
+### Closing and canceling
+
+An overlay may be hidden by closing or canceling. The difference between close and cancel is user
+intent. Closing generally implies that the user acknowledged the content on the overlay. By default,
+it will cancel whenever the user taps outside it or presses the escape key. This behavior is
+configurable with the `no-cancel-on-esc-key` and the `no-cancel-on-outside-click` properties.
+`close()` should be called explicitly by the implementer when the user interacts with a control
+in the overlay element. When the dialog is canceled, the overlay fires an 'iron-overlay-canceled'
+event. Call `preventDefault` on this event to prevent the overlay from closing.
+
+### Positioning
+
+By default the element is sized and positioned to fit and centered inside the window. You can
+position and size it manually using CSS. See `Polymer.IronFitBehavior`.
+
+### Backdrop
+
+Set the `with-backdrop` attribute to display a backdrop behind the overlay. The backdrop is
+appended to `<body>` and is of type `<iron-overlay-backdrop>`. See its doc page for styling
+options.
+
+In addition, `with-backdrop` will wrap the focus within the content in the light DOM.
+Override the [`_focusableNodes` getter](#Polymer.IronOverlayBehavior:property-_focusableNodes)
+to achieve a different behavior.
+
+### Limitations
+
+The element is styled to appear on top of other content by setting its `z-index` property. You
+must ensure no element has a stacking context with a higher `z-index` than its parent stacking
+context. You should place this element as a child of `<body>` whenever possible.
+
+
+
+##&lt;iron-overlay-backdrop&gt;
+
+`iron-overlay-backdrop` is a backdrop used by `Polymer.IronOverlayBehavior`. It should be a
+singleton.
+
+### Styling
+
+The following custom properties and mixins are available for styling.
+
+| Custom property | Description | Default |
+| --- | --- | --- |
+| `--iron-overlay-backdrop-background-color` | Backdrop background color | #000 |
+| `--iron-overlay-backdrop-opacity` | Backdrop opacity | 0.6 |
+| `--iron-overlay-backdrop` | Mixin applied to `iron-overlay-backdrop`. | {} |
+| `--iron-overlay-backdrop-opened` | Mixin applied to `iron-overlay-backdrop` when it is displayed | {} |
+

+  /**
+  Use `Polymer.IronOverlayBehavior` to implement an element that can be hidden or shown, and displays
+  on top of other content. It includes an optional backdrop, and can be used to implement a variety
+  of UI controls including dialogs and drop downs. Multiple overlays may be displayed at once.
+
+  See the [demo source code](https://github.com/PolymerElements/iron-overlay-behavior/blob/master/demo/simple-overlay.html)
+  for an example.
+
+  ### Closing and canceling
+
+  An overlay may be hidden by closing or canceling. The difference between close and cancel is user
+  intent. Closing generally implies that the user acknowledged the content on the overlay. By default,
+  it will cancel whenever the user taps outside it or presses the escape key. This behavior is
+  configurable with the `no-cancel-on-esc-key` and the `no-cancel-on-outside-click` properties.
+  `close()` should be called explicitly by the implementer when the user interacts with a control
+  in the overlay element. When the dialog is canceled, the overlay fires an 'iron-overlay-canceled'
+  event. Call `preventDefault` on this event to prevent the overlay from closing.
+
+  ### Positioning
+
+  By default the element is sized and positioned to fit and centered inside the window. You can
+  position and size it manually using CSS. See `Polymer.IronFitBehavior`.
+
+  ### Backdrop
+
+  Set the `with-backdrop` attribute to display a backdrop behind the overlay. The backdrop is
+  appended to `<body>` and is of type `<iron-overlay-backdrop>`. See its doc page for styling
+  options.
+
+  In addition, `with-backdrop` will wrap the focus within the content in the light DOM.
+  Override the [`_focusableNodes` getter](#Polymer.IronOverlayBehavior:property-_focusableNodes)
+  to achieve a different behavior.
+
+  ### Limitations
+
+  The element is styled to appear on top of other content by setting its `z-index` property. You
+  must ensure no element has a stacking context with a higher `z-index` than its parent stacking
+  context. You should place this element as a child of `<body>` whenever possible.

+# Polymer Elements
+## Guide for Contributors
+
+Polymer Elements are built in the open, and the Polymer authors eagerly encourage any and all forms of community contribution. When contributing, please follow these guidelines:
+
+### Filing Issues
+
+**If you are filing an issue to request a feature**, please provide a clear description of the feature. It can be helpful to describe answers to the following questions:
+
+ 1. **Who will use the feature?** _“As someone filling out a form…”_
+ 2. **When will they use the feature?** _“When I enter an invalid value…”_
+ 3. **What is the user’s goal?** _“I want to be visually notified that the value needs to be corrected…”_
+
+**If you are filing an issue to report a bug**, please provide:
+
+ 1. **A clear description of the bug and related expectations.** Consider using the following example template for reporting a bug:
+
+ ```markdown
+ The `paper-foo` element causes the page to turn pink when clicked.
+
+ ## Expected outcome
+
+ The page stays the same color.
+
+ ## Actual outcome
+
+ The page turns pink.
+
+ ## Steps to reproduce
+
+ 1. Put a `paper-foo` element in the page.
+ 2. Open the page in a web browser.
+ 3. Click the `paper-foo` element.
+ ```
+
+ 2. **A reduced test case that demonstrates the problem.** If possible, please include the test case as a JSBin. Start with this template to easily import and use relevant Polymer Elements: [https://jsbin.com/cagaye/edit?html,output](https://jsbin.com/cagaye/edit?html,output).
+
+ 3. **A list of browsers where the problem occurs.** This can be skipped if the problem is the same across all browsers.
+
+### Submitting Pull Requests
+
+**Before creating a pull request**, please ensure that an issue exists for the corresponding change in the pull request that you intend to make. **If an issue does not exist, please create one per the guidelines above**. The goal is to discuss the design and necessity of the proposed change with Polymer authors and community before diving into a pull request.
+
+When submitting pull requests, please provide:
+
+ 1. **A reference to the corresponding issue** or issues that will be closed by the pull request. Please refer to these issues in the pull request description using the following syntax:
+
+ ```markdown
+ (For a single issue)
+ Fixes #20
+
+ (For multiple issues)
+ Fixes #32, fixes #40
+ ```
+
+ 2. **A succinct description of the design** used to fix any related issues. For example:
+
+ ```markdown
+ This fixes #20 by removing styles that leaked which would cause the page to turn pink whenever `paper-foo` is clicked.
+ ```
+
+ 3. **At least one test for each bug fixed or feature added** as part of the pull request. Pull requests that fix bugs or add features without accompanying tests will not be considered.
+
+If a proposed change contains multiple commits, please [squash commits](https://www.google.com/url?q=http://blog.steveklabnik.com/posts/2012-11-08-how-to-squash-commits-in-a-github-pull-request) to as few as is necessary to succinctly express the change. A Polymer author can help you squash commits, so don’t be afraid to ask us if you need help with that!

+##&lt;iron-pages&gt;
+
+`iron-pages` is used to select one of its children to show. One use is to cycle through a list of
+children "pages".
+
+Example:
+
+```html
+<iron-pages selected="0">
+  <div>One</div>
+  <div>Two</div>
+  <div>Three</div>
+</iron-pages>
+
+<script>
+  document.addEventListener('click', function(e) {
+    var pages = document.querySelector('iron-pages');
+    pages.selectNext();
+  });
+</script>
+```

+## Guide for Contributors
+
+Polymer Elements are built in the open, and the Polymer authors eagerly encourage any and all forms of community contribution. When contributing, please follow these guidelines:
+
+### Filing Issues
+
+**If you are filing an issue to request a feature**, please provide a clear description of the feature. It can be helpful to describe answers to the following questions:
+
+ 1. **Who will use the feature?** _“As someone filling out a form…”_
+ 2. **When will they use the feature?** _“When I enter an invalid value…”_
+ 3. **What is the user’s goal?** _“I want to be visually notified that the value needs to be corrected…”_
+
+**If you are filing an issue to report a bug**, please provide:
+
+ 1. **A clear description of the bug and related expectations.** Consider using the following example template for reporting a bug:
+
+ ```markdown
+ The `paper-foo` element causes the page to turn pink when clicked.
+
+ ## Expected outcome
+
+ The page stays the same color.
+
+ ## Actual outcome
+
+ The page turns pink.
+
+ ## Steps to reproduce
+
+ 1. Put a `paper-foo` element in the page.
+ 2. Open the page in a web browser.
+ 3. Click the `paper-foo` element.
+ ```
+
+ 2. **A reduced test case that demonstrates the problem.** If possible, please include the test case as a JSBin. Start with this template to easily import and use relevant Polymer Elements: [https://jsbin.com/cagaye/edit?html,output](https://jsbin.com/cagaye/edit?html,output).
+
+ 3. **A list of browsers where the problem occurs.** This can be skipped if the problem is the same across all browsers.
+
+### Submitting Pull Requests
+
+**Before creating a pull request**, please ensure that an issue exists for the corresponding change in the pull request that you intend to make. **If an issue does not exist, please create one per the guidelines above**. The goal is to discuss the design and necessity of the proposed change with Polymer authors and community before diving into a pull request.

+ 1. **A reference to the corresponding issue** or issues that will be closed by the pull request. Please refer to these issues in the pull request description using the following syntax:
+
+ ```markdown
+ (For a single issue)
+ Fixes #20
+
+ (For multiple issues)
+ Fixes #32, fixes #40
+ ```
+
+ 2. **A succinct description of the design** used to fix any related issues. For example:
+
+ ```markdown
+ This fixes #20 by removing styles that leaked which would cause the page to turn pink whenever `paper-foo` is clicked.
+ ```
+
+ 3. **At least one test for each bug fixed or feature added** as part of the pull request. Pull requests that fix bugs or add features without accompanying tests will not be considered.
+
+If a proposed change contains multiple commits, please [squash commits](https://www.google.com/url?q=http://blog.steveklabnik.com/posts/2012-11-08-how-to-squash-commits-in-a-github-pull-request) to as few as is necessary to succinctly express the change. A Polymer author can help you squash commits, so don’t be afraid to ask us if you need help with that!

+# Polymer Elements
+## Guide for Contributors
+
+Polymer Elements are built in the open, and the Polymer authors eagerly encourage any and all forms of community contribution. When contributing, please follow these guidelines:
+
+### Filing Issues
+
+**If you are filing an issue to request a feature**, please provide a clear description of the feature. It can be helpful to describe answers to the following questions:
+
+ 1. **Who will use the feature?** _“As someone filling out a form…”_
+ 2. **When will they use the feature?** _“When I enter an invalid value…”_
+ 3. **What is the user’s goal?** _“I want to be visually notified that the value needs to be corrected…”_
+
+**If you are filing an issue to report a bug**, please provide:
+
+ 1. **A clear description of the bug and related expectations.** Consider using the following example template for reporting a bug:
+
+ ```markdown
+ The `paper-foo` element causes the page to turn pink when clicked.
+
+ ## Expected outcome
+
+ The page stays the same color.
+
+ ## Actual outcome
+
+ The page turns pink.
+
+ ## Steps to reproduce
+
+ 1. Put a `paper-foo` element in the page.
+ 2. Open the page in a web browser.
+ 3. Click the `paper-foo` element.
+ ```
+
+ 2. **A reduced test case that demonstrates the problem.** If possible, please include the test case as a JSBin. Start with this template to easily import and use relevant Polymer Elements: [https://jsbin.com/cagaye/edit?html,output](https://jsbin.com/cagaye/edit?html,output).
+
+ 3. **A list of browsers where the problem occurs.** This can be skipped if the problem is the same across all browsers.
+
+### Submitting Pull Requests
+
+**Before creating a pull request**, please ensure that an issue exists for the corresponding change in the pull request that you intend to make. **If an issue does not exist, please create one per the guidelines above**. The goal is to discuss the design and necessity of the proposed change with Polymer authors and community before diving into a pull request.
+
+When submitting pull requests, please provide:
+
+ 1. **A reference to the corresponding issue** or issues that will be closed by the pull request. Please refer to these issues in the pull request description using the following syntax:
+
+ ```markdown
+ (For a single issue)
+ Fixes #20
+
+ (For multiple issues)
+ Fixes #32, fixes #40
+ ```
+
+ 2. **A succinct description of the design** used to fix any related issues. For example:
+
+ ```markdown
+ This fixes #20 by removing styles that leaked which would cause the page to turn pink whenever `paper-foo` is clicked.
+ ```
+
+ 3. **At least one test for each bug fixed or feature added** as part of the pull request. Pull requests that fix bugs or add features without accompanying tests will not be considered.
+
+If a proposed change contains multiple commits, please [squash commits](https://www.google.com/url?q=http://blog.steveklabnik.com/posts/2012-11-08-how-to-squash-commits-in-a-github-pull-request) to as few as is necessary to succinctly express the change. A Polymer author can help you squash commits, so don’t be afraid to ask us if you need help with that!

+##Polymer.IronResizableBehavior
+
+`IronResizableBehavior` is a behavior that can be used in Polymer elements to
+coordinate the flow of resize events between "resizers" (elements that control the
+size or hidden state of their children) and "resizables" (elements that need to be
+notified when they are resized or un-hidden by their parents in order to take
+action on their new measurements).
+
+Elements that perform measurement should add the `IronResizableBehavior` behavior to
+their element definition and listen for the `iron-resize` event on themselves.
+This event will be fired when they become showing after having been hidden,
+when they are resized explicitly by another resizable, or when the window has been
+resized.
+
+Note, the `iron-resize` event is non-bubbling.
+

+# Polymer Elements
+## Guide for Contributors
+
+Polymer Elements are built in the open, and the Polymer authors eagerly encourage any and all forms of community contribution. When contributing, please follow these guidelines:
+
+### Filing Issues
+
+**If you are filing an issue to request a feature**, please provide a clear description of the feature. It can be helpful to describe answers to the following questions:
+
+ 1. **Who will use the feature?** _“As someone filling out a form…”_
+ 2. **When will they use the feature?** _“When I enter an invalid value…”_
+ 3. **What is the user’s goal?** _“I want to be visually notified that the value needs to be corrected…”_
+
+**If you are filing an issue to report a bug**, please provide:
+
+ 1. **A clear description of the bug and related expectations.** Consider using the following example template for reporting a bug:
+
+ ```markdown
+ The `paper-foo` element causes the page to turn pink when clicked.
+
+ ## Expected outcome
+
+ The page stays the same color.
+
+ ## Actual outcome
+
+ The page turns pink.
+
+ ## Steps to reproduce
+
+ 1. Put a `paper-foo` element in the page.
+ 2. Open the page in a web browser.
+ 3. Click the `paper-foo` element.
+ ```
+
+ 2. **A reduced test case that demonstrates the problem.** If possible, please include the test case as a JSBin. Start with this template to easily import and use relevant Polymer Elements: [https://jsbin.com/cagaye/edit?html,output](https://jsbin.com/cagaye/edit?html,output).
+
+ 3. **A list of browsers where the problem occurs.** This can be skipped if the problem is the same across all browsers.
+
+### Submitting Pull Requests
+
+**Before creating a pull request**, please ensure that an issue exists for the corresponding change in the pull request that you intend to make. **If an issue does not exist, please create one per the guidelines above**. The goal is to discuss the design and necessity of the proposed change with Polymer authors and community before diving into a pull request.
+
+When submitting pull requests, please provide:
+
+ 1. **A reference to the corresponding issue** or issues that will be closed by the pull request. Please refer to these issues in the pull request description using the following syntax:
+
+ ```markdown
+ (For a single issue)
+ Fixes #20
+
+ (For multiple issues)
+ Fixes #32, fixes #40
+ ```
+
+ 2. **A succinct description of the design** used to fix any related issues. For example:
+
+ ```markdown
+ This fixes #20 by removing styles that leaked which would cause the page to turn pink whenever `paper-foo` is clicked.
+ ```
+
+ 3. **At least one test for each bug fixed or feature added** as part of the pull request. Pull requests that fix bugs or add features without accompanying tests will not be considered.
+
+If a proposed change contains multiple commits, please [squash commits](https://www.google.com/url?q=http://blog.steveklabnik.com/posts/2012-11-08-how-to-squash-commits-in-a-github-pull-request) to as few as is necessary to succinctly express the change. A Polymer author can help you squash commits, so don’t be afraid to ask us if you need help with that!

+
+_[Demo and API docs](https://elements.polymer-project.org/elements/iron-selector)_
+
+
+##&lt;iron-selector&gt;
+
+  `iron-selector` is an element which can be used to manage a list of elements
+  that can be selected.  Tapping on the item will make the item selected.  The `selected` indicates
+  which item is being selected.  The default is to use the index of the item.
+
+  Example:
+
+```html
+  <iron-selector selected="0">
+    <div>Item 1</div>
+    <div>Item 2</div>
+    <div>Item 3</div>
+  </iron-selector>
+```
+
+  If you want to use the attribute value of an element for `selected` instead of the index,
+  set `attrForSelected` to the name of the attribute.  For example, if you want to select item by
+  `name`, set `attrForSelected` to `name`.
+
+  Example:
+
+```html
+  <iron-selector attr-for-selected="name" selected="foo">
+    <div name="foo">Foo</div>
+    <div name="bar">Bar</div>
+    <div name="zot">Zot</div>
+  </iron-selector>
+```
+
+  You can specify a default fallback with `fallbackSelection` in case the `selected` attribute does
+  not match the `attrForSelected` attribute of any elements.
+
+  Example:
+
+```html
+    <iron-selector attr-for-selected="name" selected="non-existing"
+                   fallback-selection="default">
+      <div name="foo">Foo</div>
+      <div name="bar">Bar</div>
+      <div name="default">Default</div>
+    </iron-selector>
+```
+
+  Note: When the selector is multi, the selection will set to `fallbackSelection` iff
+  the number of matching elements is zero.
+
+  `iron-selector` is not styled. Use the `iron-selected` CSS class to style the selected element.
+
+  Example:
+
+```html
+  <style>
+    .iron-selected {
+      background: #eee;
+    }
+  </style>
+
+  ...
+
+  <iron-selector selected="0">
+    <div>Item 1</div>
+    <div>Item 2</div>
+    <div>Item 3</div>
+  </iron-selector>
+```

+  /**
+  `iron-selector` is an element which can be used to manage a list of elements
+  that can be selected.  Tapping on the item will make the item selected.  The `selected` indicates
+  which item is being selected.  The default is to use the index of the item.
+
+  Example:
+
+      <iron-selector selected="0">
+        <div>Item 1</div>
+        <div>Item 2</div>
+        <div>Item 3</div>
+      </iron-selector>
+
+  If you want to use the attribute value of an element for `selected` instead of the index,
+  set `attrForSelected` to the name of the attribute.  For example, if you want to select item by
+  `name`, set `attrForSelected` to `name`.
+
+  Example:
+
+      <iron-selector attr-for-selected="name" selected="foo">
+        <div name="foo">Foo</div>
+        <div name="bar">Bar</div>
+        <div name="zot">Zot</div>
+      </iron-selector>
+
+  You can specify a default fallback with `fallbackSelection` in case the `selected` attribute does
+  not match the `attrForSelected` attribute of any elements.
+
+  Example:
+
+        <iron-selector attr-for-selected="name" selected="non-existing"
+                       fallback-selection="default">
+          <div name="foo">Foo</div>
+          <div name="bar">Bar</div>
+          <div name="default">Default</div>
+        </iron-selector>
+
+  Note: When the selector is multi, the selection will set to `fallbackSelection` iff
+  the number of matching elements is zero.
+

+# Polymer Elements
+## Guide for Contributors
+
+Polymer Elements are built in the open, and the Polymer authors eagerly encourage any and all forms of community contribution. When contributing, please follow these guidelines:
+
+### Filing Issues
+
+**If you are filing an issue to request a feature**, please provide a clear description of the feature. It can be helpful to describe answers to the following questions:
+
+ 1. **Who will use the feature?** _“As someone filling out a form…”_
+ 2. **When will they use the feature?** _“When I enter an invalid value…”_
+ 3. **What is the user’s goal?** _“I want to be visually notified that the value needs to be corrected…”_
+
+**If you are filing an issue to report a bug**, please provide:
+
+ 1. **A clear description of the bug and related expectations.** Consider using the following example template for reporting a bug:
+
+ ```markdown
+ The `paper-foo` element causes the page to turn pink when clicked.
+
+ ## Expected outcome
+
+ The page stays the same color.
+
+ ## Actual outcome
+
+ The page turns pink.
+
+ ## Steps to reproduce
+
+ 1. Put a `paper-foo` element in the page.
+ 2. Open the page in a web browser.
+ 3. Click the `paper-foo` element.
+ ```
+
+ 2. **A reduced test case that demonstrates the problem.** If possible, please include the test case as a JSBin. Start with this template to easily import and use relevant Polymer Elements: [https://jsbin.com/cagaye/edit?html,output](https://jsbin.com/cagaye/edit?html,output).
+
+ 3. **A list of browsers where the problem occurs.** This can be skipped if the problem is the same across all browsers.
+
+### Submitting Pull Requests
+
+**Before creating a pull request**, please ensure that an issue exists for the corresponding change in the pull request that you intend to make. **If an issue does not exist, please create one per the guidelines above**. The goal is to discuss the design and necessity of the proposed change with Polymer authors and community before diving into a pull request.
+
+When submitting pull requests, please provide:
+
+ 1. **A reference to the corresponding issue** or issues that will be closed by the pull request. Please refer to these issues in the pull request description using the following syntax:
+
+ ```markdown
+ (For a single issue)
+ Fixes #20
+
+ (For multiple issues)
+ Fixes #32, fixes #40
+ ```
+
+ 2. **A succinct description of the design** used to fix any related issues. For example:
+
+ ```markdown
+ This fixes #20 by removing styles that leaked which would cause the page to turn pink whenever `paper-foo` is clicked.
+ ```
+
+ 3. **At least one test for each bug fixed or feature added** as part of the pull request. Pull requests that fix bugs or add features without accompanying tests will not be considered.
+
+If a proposed change contains multiple commits, please [squash commits](https://www.google.com/url?q=http://blog.steveklabnik.com/posts/2012-11-08-how-to-squash-commits-in-a-github-pull-request) to as few as is necessary to succinctly express the change. A Polymer author can help you squash commits, so don’t be afraid to ask us if you need help with that!

+
+##Polymer.IronValidatableBehavior
+
+`Use Polymer.IronValidatableBehavior` to implement an element that validates user input.
+Use the related `Polymer.IronValidatorBehavior` to add custom validation logic to an iron-input.
+
+By default, an `<iron-form>` element validates its fields when the user presses the submit button.
+To validate a form imperatively, call the form's `validate()` method, which in turn will
+call `validate()` on all its children. By using `Polymer.IronValidatableBehavior`, your
+custom element will get a public `validate()`, which
+will return the validity of the element, and a corresponding `invalid` attribute,
+which can be used for styling.
+
+To implement the custom validation logic of your element, you must override
+the protected `_getValidity()` method of this behaviour, rather than `validate()`.
+See [this](https://github.com/PolymerElements/iron-form/blob/master/demo/simple-element.html)
+for an example.
+
+### Accessibility
+
+Changing the `invalid` property, either manually or by calling `validate()` will update the
+`aria-invalid` attribute.

+# neon-animation
+
+`neon-animation` is a suite of elements and behaviors to implement pluggable animated transitions for Polymer Elements using [Web Animations](https://w3c.github.io/web-animations/).
+
+*Warning: The API may change.*

+
+<a name="basic"></a>
+## A basic animatable element
+
+Elements that can be animated should implement the `Polymer.NeonAnimatableBehavior` behavior, or `Polymer.NeonAnimationRunnerBehavior` if they're also responsible for running an animation.
+
+```js
+Polymer({
+  is: 'my-animatable',
+  behaviors: [
+    Polymer.NeonAnimationRunnerBehavior
+  ],
+  properties: {
+    animationConfig: {
+      value: function() {
+        return {
+          // provided by neon-animation/animations/scale-down-animation.html
+          name: 'scale-down-animation',
+          node: this
+        }
+      }
+    }
+  },
+  listeners: {
+    // this event is fired when the animation finishes
+    'neon-animation-finish': '_onNeonAnimationFinish'
+  },
+  animate: function() {
+    // run scale-down-animation
+    this.playAnimation();
+  },
+  _onNeonAnimationFinish: function() {
+    console.log('animation done!');
+  }
+});
+```
+
+[Live demo](http://morethanreal.github.io/neon-animation-demo/bower_components/neon-animation/demo/doc/basic.html)
+
+<a name="configuration"></a>
+## Animation configuration
+
+<a name="configuration-types"></a>
+### Animation types
+
+An element might run different animations, for example it might do something different when it enters the view and when it exits from view. You can set the `animationConfig` property to a map from an animation type to configuration.
+
+```js
+Polymer({
+  is: 'my-dialog',
+  behaviors: [
+    Polymer.NeonAnimationRunnerBehavior
+  ],
+  properties: {
+    opened: {
+      type: Boolean
+    },
+    animationConfig: {
+      value: function() {
+        return {
+          'entry': {
+            // provided by neon-animation/animations/scale-up-animation.html
+            name: 'scale-up-animation',
+            node: this
+          },
+          'exit': {
+            // provided by neon-animation/animations/fade-out-animation.html
+            name: 'fade-out-animation',
+            node: this
+          }
+        }
+      }
+    }
+  },
+  listeners: {
+    'neon-animation-finish': '_onNeonAnimationFinish'
+  },
+  show: function() {
+    this.opened = true;
+    this.style.display = 'inline-block';
+    // run scale-up-animation
+    this.playAnimation('entry');
+  },
+  hide: function() {
+    this.opened = false;
+    // run fade-out-animation
+    this.playAnimation('exit');
+  },
+  _onNeonAnimationFinish: function() {
+    if (!this.opened) {
+      this.style.display = 'none';
+    }
+  }
+});
+```
+
+[Live demo](http://morethanreal.github.io/neon-animation-demo/bower_components/neon-animation/demo/doc/types.html)
+
+You can also use the convenience properties `entryAnimation` and `exitAnimation` to set `entry` and `exit` animations:
+
+```js
+properties: {
+  entryAnimation: {
+    value: 'scale-up-animation'
+  },
+  exitAnimation: {
+    value: 'fade-out-animation'
+  }
+}
+```
+
+<a name="configuration-properties"></a>
+### Configuration properties
+
+You can pass additional parameters to configure an animation in the animation configuration object.
+All animations should accept the following properties:
+
+ * `name`: The name of an animation, ie. an element implementing `Polymer.NeonAnimationBehavior`.
+ * `node`: The target node to apply the animation to. Defaults to `this`.
+ * `timing`: Timing properties to use in this animation. They match the [Web Animations Animation Effect Timing interface](https://w3c.github.io/web-animations/#the-animationeffecttiming-interface). The
+ properties include the following:
+     * `duration`: The duration of the animation in milliseconds.
+     * `delay`: The delay before the start of the animation in milliseconds.
+     * `easing`: A timing function for the animation. Matches the CSS timing function values.
+
+Animations may define additional configuration properties and they are listed in their documentation.
+
+<a name="configuration-multiple"></a>
+### Using multiple animations
+
+Set the animation configuration to an array to combine animations, like this:
+
+```js
+animationConfig: {
+  value: function() {
+    return {
+      // fade-in-animation is run with a 50ms delay from slide-down-animation
+      'entry': [{
+        name: 'slide-down-animation',
+        node: this
+      }, {
+        name: 'fade-in-animation',
+        node: this,
+        timing: {delay: 50}
+      }]
+    }
+  }
+}
+```
+
+<a name="configuration-encapsulation"></a>
+### Running animations encapsulated in children nodes
+
+You can include animations in the configuration that are encapsulated in a child element that implement `Polymer.NeonAnimatableBehavior` with the `animatable` property.
+
+```js
+animationConfig: {
+  value: function() {
+    return {
+      // run fade-in-animation on this, and the entry animation on this.$.myAnimatable
+      'entry': [
+        {name: 'fade-in-animation', node: this},
+        {animatable: this.$.myAnimatable, type: 'entry'}
+      ]
+    }
+  }
+}
+```
+
+<a name="page-transitions"></a>
+## Page transitions
+
+*The artist formerly known as `<core-animated-pages>`*
+
+The `neon-animated-pages` element manages a set of pages to switch between, and runs animations between the page transitions. It implements the `Polymer.IronSelectableBehavior` behavior. Each child node should implement `Polymer.NeonAnimatableBehavior` and define the `entry` and `exit` animations. During a page transition, the `entry` animation is run on the new page and the `exit` animation is run on the old page.
+
+<a name="shared-element"></a>
+### Shared element animations
+
+Shared element animations work on multiple nodes. For example, a "hero" animation is used during a page transition to make two elements from separate pages appear to animate as a single element. Shared element animation configurations have an `id` property that identify they belong in the same animation. Elements containing shared elements also have a `sharedElements` property defines a map from `id` to element, the element involved with the animation.
+
+In the incoming page:
+
+```js
+properties: {
+  animationConfig: {
+    value: function() {
+      return {
+        // the incoming page defines the 'entry' animation
+        'entry': {
+          name: 'hero-animation',
+          id: 'hero',
+          toPage: this
+        }
+      }
+    }
+  },
+  sharedElements: {
+    value: function() {
+      return {
+        'hero': this.$.hero
+      }
+    }
+  }
+}
+```
+
+In the outgoing page:
+
+```js
+properties: {
+  animationConfig: {
+    value: function() {
+      return {
+        // the outgoing page defines the 'exit' animation
+        'exit': {
+          name: 'hero-animation',
+          id: 'hero',
+          fromPage: this
+        }
+      }
+    }
+  },
+  sharedElements: {
+    value: function() {
+      return {
+        'hero': this.$.otherHero
+      }
+    }
+  }
+}
+```
+
+<a name="declarative-page"></a>
+### Declarative page transitions
+
+For convenience, if you define the `entry-animation` and `exit-animation` attributes on `<neon-animated-pages>`, those animations will apply for all page transitions.
+
+For example:
+
+```js
+<neon-animated-pages id="pages" class="flex" selected="[[selected]]" entry-animation="slide-from-right-animation" exit-animation="slide-left-animation">
+  <neon-animatable>1</neon-animatable>
+  <neon-animatable>2</neon-animatable>
+  <neon-animatable>3</neon-animatable>
+  <neon-animatable>4</neon-animatable>
+  <neon-animatable>5</neon-animatable>
+</neon-animated-pages>
+```
+
+The new page will slide in from the right, and the old page slide away to the left.
+
+<a name="animations"></a>
+## Included animations
+
+Single element animations:
+
+ * `fade-in-animation` Animates opacity from `0` to `1`;
+ * `fade-out-animation` Animates opacity from `1` to `0`;
+ * `scale-down-animation` Animates transform from `scale(1)` to `scale(0)`;
+ * `scale-up-animation` Animates transform from `scale(0)` to `scale(1)`;
+ * `slide-down-animation` Animates transform from `none` to `translateY(100%)`;
+ * `slide-up-animation` Animates transform from `none` to `translateY(-100%)`;
+ * `slide-from-top-animation` Animates transform from `translateY(-100%)` to `none`;
+ * `slide-from-bottom-animation` Animates transform from `translateY(100%)` to `none`;
+ * `slide-left-animation` Animates transform from `none` to `translateX(-100%)`;
+ * `slide-right-animation` Animates transform from `none` to `translateX(100%)`;
+ * `slide-from-left-animation` Animates transform from `translateX(-100%)` to `none`;
+ * `slide-from-right-animation` Animates transform from `translateX(100%)` to `none`;
+ * `transform-animation` Animates a custom transform.
+
+Note that there is a restriction that only one transform animation can be applied on the same element at a time. Use the custom `transform-animation` to combine transform properties.
+
+Shared element animations
+
+ * `hero-animation` Animates an element such that it looks like it scales and transforms from another element.
+ * `ripple-animation` Animates an element to full screen such that it looks like it ripples from another element.
+
+Group animations
+ * `cascaded-animation` Applys an animation to an array of elements with a delay between each.

+## Animation configuration
+
+<a name="configuration-types"></a>
+### Animation types
+
+An element might run different animations, for example it might do something different when it enters the view and when it exits from view. You can set the `animationConfig` property to a map from an animation type to configuration.
+
+```js
+Polymer({
+  is: 'my-dialog',
+  behaviors: [
+    Polymer.NeonAnimationRunnerBehavior
+  ],
+  properties: {
+    opened: {
+      type: Boolean
+    },
+    animationConfig: {
+      value: function() {
+        return {
+          'entry': {
+            // provided by neon-animation/animations/scale-up-animation.html
+            name: 'scale-up-animation',
+            node: this
+          },
+          'exit': {
+            // provided by neon-animation-animations/fade-out-animation.html
+            name: 'fade-out-animation',
+            node: this
+          }
+        }
+      }
+    }
+  },
+  listeners: {
+    'neon-animation-finish': '_onNeonAnimationFinish'
+  },
+  show: function() {
+    this.opened = true;
+    this.style.display = 'inline-block';
+    // run scale-up-animation
+    this.playAnimation('entry');
+  },
+  hide: function() {
+    this.opened = false;
+    // run fade-out-animation
+    this.playAnimation('exit');
+  },
+  _onNeonAnimationFinish: function() {
+    if (!this.opened) {
+      this.style.display = 'none';
+    }
+  }
+});
+```
+
+[Live demo](http://morethanreal.github.io/neon-animation-demo/bower_components/neon-animation/demo/doc/types.html)
+
+You can also use the convenience properties `entryAnimation` and `exitAnimation` to set `entry` and `exit` animations:
+
+```js
+properties: {
+  entryAnimation: {
+    value: 'scale-up-animation'
+  },
+  exitAnimation: {
+    value: 'fade-out-animation'
+  }
+}
+```
+
+<a name="configuration-properties"></a>
+### Configuration properties
+
+You can pass additional parameters to configure an animation in the animation configuration object.
+All animations should accept the following properties:
+
+ * `name`: The name of an animation, ie. an element implementing `Polymer.NeonAnimationBehavior`.
+ * `node`: The target node to apply the animation to. Defaults to `this`.
+ * `timing`: Timing properties to use in this animation. They match the [Web Animations Animation Effect Timing interface](https://w3c.github.io/web-animations/#the-animationeffecttiming-interface). The
+ properties include the following:
+     * `duration`: The duration of the animation in milliseconds.
+     * `delay`: The delay before the start of the animation in milliseconds.
+     * `easing`: A timing function for the animation. Matches the CSS timing function values.
+
+Animations may define additional configuration properties and they are listed in their documentation.
+
+<a name="configuration-multiple"></a>
+### Using multiple animations
+
+Set the animation configuration to an array to combine animations, like this:
+
+```js
+animationConfig: {
+  value: function() {
+    return {
+      // fade-in-animation is run with a 50ms delay from slide-down-animation
+      'entry': [{
+        name: 'slide-down-animation',
+        node: this
+      }, {
+        name: 'fade-in-animation',
+        node: this,
+        timing: {delay: 50}
+      }]
+    }
+  }
+}
+```
+
+<a name="configuration-encapsulation"></a>
+### Running animations encapsulated in children nodes
+
+You can include animations in the configuration that are encapsulated in a child element that implement `Polymer.NeonAnimatableBehavior` with the `animatable` property.
+
+```js
+animationConfig: {
+  value: function() {
+    return {
+      // run fade-in-animation on this, and the entry animation on this.$.myAnimatable
+      'entry': [
+        {name: 'fade-in-animation', node: this},
+        {animatable: this.$.myAnimatable, type: 'entry'}
+      ]
+    }
+  }
+}
+```
+
+<a name="page-transitions"></a>
+## Page transitions
+
+*The artist formerly known as `<core-animated-pages>`*
+
+The `neon-animated-pages` element manages a set of pages to switch between, and runs animations between the page transitions. It implements the `Polymer.IronSelectableBehavior` behavior. Each child node should implement `Polymer.NeonAnimatableBehavior` and define the `entry` and `exit` animations. During a page transition, the `entry` animation is run on the new page and the `exit` animation is run on the old page.
+
+<a name="shared-element"></a>
+### Shared element animations
+
+Shared element animations work on multiple nodes. For example, a "hero" animation is used during a page transition to make two elements from separate pages appear to animate as a single element. Shared element animation configurations have an `id` property that identify they belong in the same animation. Elements containing shared elements also have a `sharedElements` property defines a map from `id` to element, the element involved with the animation.
+
+In the incoming page:
+
+```js
+properties: {
+  animationConfig: {
+    value: function() {
+      return {
+        // the incoming page defines the 'entry' animation
+        'entry': {
+          name: 'hero-animation',
+          id: 'hero',
+          toPage: this
+        }
+      }
+    }
+  },
+  sharedElements: {
+    value: function() {
+      return {
+        'hero': this.$.hero
+      }
+    }
+  }
+}
+```
+
+In the outgoing page:
+
+```js
+properties: {
+  animationConfig: {
+    value: function() {
+      return {
+        // the outgoing page defines the 'exit' animation
+        'exit': {
+          name: 'hero-animation',
+          id: 'hero',
+          fromPage: this
+        }
+      }
+    }
+  },
+  sharedElements: {
+    value: function() {
+      return {
+        'hero': this.$.otherHero
+      }
+    }
+  }
+}
+```
+
+<a name="declarative-page"></a>
+### Declarative page transitions
+
+For convenience, if you define the `entry-animation` and `exit-animation` attributes on `<neon-animated-pages>`, those animations will apply for all page transitions.
+
+For example:
+
+```js
+<neon-animated-pages id="pages" class="flex" selected="[[selected]]" entry-animation="slide-from-right-animation" exit-animation="slide-left-animation">
+  <neon-animatable>1</neon-animatable>
+  <neon-animatable>2</neon-animatable>
+  <neon-animatable>3</neon-animatable>
+  <neon-animatable>4</neon-animatable>
+  <neon-animatable>5</neon-animatable>
+</neon-animated-pages>
+```
+
+The new page will slide in from the right, and the old page slide away to the left.
+
+<a name="animations"></a>
+## Included animations
+
+Single element animations:
+
+ * `fade-in-animation` Animates opacity from `0` to `1`;
+ * `fade-out-animation` Animates opacity from `1` to `0`;
+ * `scale-down-animation` Animates transform from `scale(1)` to `scale(0)`;
+ * `scale-up-animation` Animates transform from `scale(0)` to `scale(1)`;
+ * `slide-down-animation` Animates transform from `none` to `translateY(100%)`;
+ * `slide-up-animation` Animates transform from `none` to `translateY(-100%)`;
+ * `slide-from-top-animation` Animates transform from `translateY(-100%)` to `none`;
+ * `slide-from-bottom-animation` Animates transform from `translateY(100%)` to `none`;
+ * `slide-left-animation` Animates transform from `none` to `translateX(-100%)`;
+ * `slide-right-animation` Animates transform from `none` to `translateX(100%)`;
+ * `slide-from-left-animation` Animates transform from `translateX(-100%)` to `none`;
+ * `slide-from-right-animation` Animates transform from `translateX(100%)` to `none`;
+ * `transform-animation` Animates a custom transform.
+
+Note that there is a restriction that only one transform animation can be applied on the same element at a time. Use the custom `transform-animation` to combine transform properties.
+
+Shared element animations
+
+ * `hero-animation` Animates an element such that it looks like it scales and transforms from another element.
+ * `ripple-animation` Animates an element to full screen such that it looks like it ripples from another element.
+
+Group animations
+ * `cascaded-animation` Applys an animation to an array of elements with a delay between each.

+# Polymer Elements
+## Guide for Contributors
+
+Polymer Elements are built in the open, and the Polymer authors eagerly encourage any and all forms of community contribution. When contributing, please follow these guidelines:
+
+### Filing Issues
+
+**If you are filing an issue to request a feature**, please provide a clear description of the feature. It can be helpful to describe answers to the following questions:
+
+ 1. **Who will use the feature?** _“As someone filling out a form…”_
+ 2. **When will they use the feature?** _“When I enter an invalid value…”_
+ 3. **What is the user’s goal?** _“I want to be visually notified that the value needs to be corrected…”_
+
+**If you are filing an issue to report a bug**, please provide:
+
+ 1. **A clear description of the bug and related expectations.** Consider using the following example template for reporting a bug:
+
+ ```markdown
+ The `paper-foo` element causes the page to turn pink when clicked.
+
+ ## Expected outcome
+
+ The page stays the same color.
+
+ ## Actual outcome
+
+ The page turns pink.
+
+ ## Steps to reproduce
+
+ 1. Put a `paper-foo` element in the page.
+ 2. Open the page in a web browser.
+ 3. Click the `paper-foo` element.
+ ```
+
+ 2. **A reduced test case that demonstrates the problem.** If possible, please include the test case as a JSBin. Start with this template to easily import and use relevant Polymer Elements: [https://jsbin.com/cagaye/edit?html,output](https://jsbin.com/cagaye/edit?html,output).
+
+ 3. **A list of browsers where the problem occurs.** This can be skipped if the problem is the same across all browsers.
+
+### Submitting Pull Requests
+
+**Before creating a pull request**, please ensure that an issue exists for the corresponding change in the pull request that you intend to make. **If an issue does not exist, please create one per the guidelines above**. The goal is to discuss the design and necessity of the proposed change with Polymer authors and community before diving into a pull request.
+
+When submitting pull requests, please provide:
+
+ 1. **A reference to the corresponding issue** or issues that will be closed by the pull request. Please refer to these issues in the pull request description using the following syntax:
+
+ ```markdown
+ (For a single issue)
+ Fixes #20
+
+ (For multiple issues)
+ Fixes #32, fixes #40
+ ```
+
+ 2. **A succinct description of the design** used to fix any related issues. For example:
+
+ ```markdown
+ This fixes #20 by removing styles that leaked which would cause the page to turn pink whenever `paper-foo` is clicked.
+ ```
+
+ 3. **At least one test for each bug fixed or feature added** as part of the pull request. Pull requests that fix bugs or add features without accompanying tests will not be considered.
+
+If a proposed change contains multiple commits, please [squash commits](https://www.google.com/url?q=http://blog.steveklabnik.com/posts/2012-11-08-how-to-squash-commits-in-a-github-pull-request) to as few as is necessary to succinctly express the change. A Polymer author can help you squash commits, so don’t be afraid to ask us if you need help with that!

+
+##Polymer.PaperCheckedElementBehavior
+
+Use `Polymer.PaperCheckedElementBehavior` to implement a custom element
+that has a `checked` property similar to `Polymer.IronCheckedElementBehavior`
+and is compatible with having a ripple effect.
+
+
+
+##Polymer.PaperInkyFocusBehavior
+
+`Polymer.PaperInkyFocusBehavior` implements a ripple when the element has keyboard focus.
+
+
+
+##Polymer.PaperRippleBehavior
+
+`Polymer.PaperRippleBehavior` dynamically implements a ripple
+when the element has focus via pointer or keyboard.
+
+NOTE: This behavior is intended to be used in conjunction with and after
+`Polymer.IronButtonState` and `Polymer.IronControlState`.

+# Polymer Elements
+## Guide for Contributors
+
+Polymer Elements are built in the open, and the Polymer authors eagerly encourage any and all forms of community contribution. When contributing, please follow these guidelines:
+
+### Filing Issues
+
+**If you are filing an issue to request a feature**, please provide a clear description of the feature. It can be helpful to describe answers to the following questions:
+
+ 1. **Who will use the feature?** _“As someone filling out a form…”_
+ 2. **When will they use the feature?** _“When I enter an invalid value…”_
+ 3. **What is the user’s goal?** _“I want to be visually notified that the value needs to be corrected…”_
+
+**If you are filing an issue to report a bug**, please provide:
+
+ 1. **A clear description of the bug and related expectations.** Consider using the following example template for reporting a bug:
+
+ ```markdown
+ The `paper-foo` element causes the page to turn pink when clicked.
+
+ ## Expected outcome
+
+ The page stays the same color.
+
+ ## Actual outcome
+
+ The page turns pink.
+
+ ## Steps to reproduce
+
+ 1. Put a `paper-foo` element in the page.
+ 2. Open the page in a web browser.
+ 3. Click the `paper-foo` element.
+ ```
+
+ 2. **A reduced test case that demonstrates the problem.** If possible, please include the test case as a JSBin. Start with this template to easily import and use relevant Polymer Elements: [https://jsbin.com/cagaye/edit?html,output](https://jsbin.com/cagaye/edit?html,output).
+
+ 3. **A list of browsers where the problem occurs.** This can be skipped if the problem is the same across all browsers.
+
+### Submitting Pull Requests
+
+**Before creating a pull request**, please ensure that an issue exists for the corresponding change in the pull request that you intend to make. **If an issue does not exist, please create one per the guidelines above**. The goal is to discuss the design and necessity of the proposed change with Polymer authors and community before diving into a pull request.
+
+When submitting pull requests, please provide:
+
+ 1. **A reference to the corresponding issue** or issues that will be closed by the pull request. Please refer to these issues in the pull request description using the following syntax:
+
+ ```markdown
+ (For a single issue)
+ Fixes #20
+
+ (For multiple issues)
+ Fixes #32, fixes #40
+ ```
+
+ 2. **A succinct description of the design** used to fix any related issues. For example:
+
+ ```markdown
+ This fixes #20 by removing styles that leaked which would cause the page to turn pink whenever `paper-foo` is clicked.
+ ```
+
+ 3. **At least one test for each bug fixed or feature added** as part of the pull request. Pull requests that fix bugs or add features without accompanying tests will not be considered.
+
+If a proposed change contains multiple commits, please [squash commits](https://www.google.com/url?q=http://blog.steveklabnik.com/posts/2012-11-08-how-to-squash-commits-in-a-github-pull-request) to as few as is necessary to succinctly express the change. A Polymer author can help you squash commits, so don’t be afraid to ask us if you need help with that!

+Material design: [Buttons](https://www.google.com/design/spec/components/buttons.html)
+
+`paper-button` is a button. When the user touches the button, a ripple effect emanates
+from the point of contact. It may be flat or raised. A raised button is styled with a
+shadow.
+
+Example:
+
+    <paper-button>Flat button</paper-button>
+    <paper-button raised>Raised button</paper-button>
+    <paper-button noink>No ripple effect</paper-button>
+    <paper-button toggles>Toggle-able button</paper-button>
+
+A button that has `toggles` true will remain `active` after being clicked (and
+will have an `active` attribute set). For more information, see the `Polymer.IronButtonState`
+behavior.
+
+You may use custom DOM in the button body to create a variety of buttons. For example, to
+create a button with an icon and some text:
+
+    <paper-button>
+      <iron-icon icon="favorite"></iron-icon>
+      custom button content
+    </paper-button>
+
+To use `paper-button` as a link, wrap it in an anchor tag. Since `paper-button` will already
+receive focus, you may want to prevent the anchor tag from receiving focus as well by setting
+its tabindex to -1.
+
+    <a href="https://www.polymer-project.org/" tabindex="-1">
+      <paper-button raised>Polymer Project</paper-button>
+    </a>
+
+### Styling
+
+Style the button with CSS as you would a normal DOM element.
+
+    paper-button.fancy {
+      background: green;
+      color: yellow;
+    }
+
+    paper-button.fancy:hover {
+      background: lime;
+    }
+
+    paper-button[disabled],
+    paper-button[toggles][active] {
+      background: red;
+    }
+
+By default, the ripple is the same color as the foreground at 25% opacity. You may
+customize the color using the `--paper-button-ink-color` custom property.
+
+The following custom properties and mixins are also available for styling:
+
+Custom property | Description | Default
+----------------|-------------|----------
+`--paper-button-ink-color` | Background color of the ripple | `Based on the button's color`
+`--paper-button` | Mixin applied to the button | `{}`
+`--paper-button-disabled` | Mixin applied to the disabled button. Note that you can also use the `paper-button[disabled]` selector | `{}`
+`--paper-button-flat-keyboard-focus` | Mixin applied to a flat button after it's been focused using the keyboard | `{}`
+`--paper-button-raised-keyboard-focus` | Mixin applied to a raised button after it's been focused using the keyboard | `{}`

+# Polymer Elements
+## Guide for Contributors
+
+Polymer Elements are built in the open, and the Polymer authors eagerly encourage any and all forms of community contribution. When contributing, please follow these guidelines:
+
+### Filing Issues
+
+**If you are filing an issue to request a feature**, please provide a clear description of the feature. It can be helpful to describe answers to the following questions:
+
+ 1. **Who will use the feature?** _“As someone filling out a form…”_
+ 2. **When will they use the feature?** _“When I enter an invalid value…”_
+ 3. **What is the user’s goal?** _“I want to be visually notified that the value needs to be corrected…”_
+
+**If you are filing an issue to report a bug**, please provide:
+
+ 1. **A clear description of the bug and related expectations.** Consider using the following example template for reporting a bug:
+
+ ```markdown
+ The `paper-foo` element causes the page to turn pink when clicked.
+
+ ## Expected outcome
+
+ The page stays the same color.
+
+ ## Actual outcome
+
+ The page turns pink.
+
+ ## Steps to reproduce
+
+ 1. Put a `paper-foo` element in the page.
+ 2. Open the page in a web browser.
+ 3. Click the `paper-foo` element.
+ ```
+
+ 2. **A reduced test case that demonstrates the problem.** If possible, please include the test case as a JSBin. Start with this template to easily import and use relevant Polymer Elements: [https://jsbin.com/cagaye/edit?html,output](https://jsbin.com/cagaye/edit?html,output).
+
+ 3. **A list of browsers where the problem occurs.** This can be skipped if the problem is the same across all browsers.
+
+### Submitting Pull Requests
+
+**Before creating a pull request**, please ensure that an issue exists for the corresponding change in the pull request that you intend to make. **If an issue does not exist, please create one per the guidelines above**. The goal is to discuss the design and necessity of the proposed change with Polymer authors and community before diving into a pull request.
+
+When submitting pull requests, please provide:
+
+ 1. **A reference to the corresponding issue** or issues that will be closed by the pull request. Please refer to these issues in the pull request description using the following syntax:
+
+ ```markdown
+ (For a single issue)
+ Fixes #20
+
+ (For multiple issues)
+ Fixes #32, fixes #40
+ ```
+
+ 2. **A succinct description of the design** used to fix any related issues. For example:
+
+ ```markdown
+ This fixes #20 by removing styles that leaked which would cause the page to turn pink whenever `paper-foo` is clicked.
+ ```
+
+ 3. **At least one test for each bug fixed or feature added** as part of the pull request. Pull requests that fix bugs or add features without accompanying tests will not be considered.
+
+If a proposed change contains multiple commits, please [squash commits](https://www.google.com/url?q=http://blog.steveklabnik.com/posts/2012-11-08-how-to-squash-commits-in-a-github-pull-request) to as few as is necessary to succinctly express the change. A Polymer author can help you squash commits, so don’t be afraid to ask us if you need help with that!

+
+_[Demo and API docs](https://elements.polymer-project.org/elements/paper-card)_
+
+
+##&lt;paper-card&gt;
+
+Material design: [Cards](https://www.google.com/design/spec/components/cards.html)
+
+`paper-card` is a container with a drop shadow.
+
+Example:
+
+```html
+<paper-card heading="Card Title">
+  <div class="card-content">Some content</div>
+  <div class="card-actions">
+    <paper-button>Some action</paper-button>
+  </div>
+</paper-card>
+```
+
+Example - top card image:
+
+```html
+<paper-card heading="Card Title" image="/path/to/image.png">
+  ...
+</paper-card>
+```
+
+### Accessibility
+
+By default, the `aria-label` will be set to the value of the `heading` attribute.
+
+### Styling
+
+The following custom properties and mixins are available for styling:
+
+| Custom property | Description | Default |
+| --- | --- | --- |
+| `--paper-card-background-color` | The background color of the card | `--primary-background-color` |
+| `--paper-card-header-color` | The color of the header text | `#000` |
+| `--paper-card-header` | Mixin applied to the card header section | `{}` |
+| `--paper-card-header-text` | Mixin applied to the title in the card header section | `{}` |
+| `--paper-card-header-image` | Mixin applied to the image in the card header section | `{}` |
+| `--paper-card-header-image-text` | Mixin applied to the text overlapping the image in the card header section | `{}` |
+| `--paper-card-content` | Mixin applied to the card content section | `{}` |
+| `--paper-card-actions` | Mixin applied to the card action section | `{}` |
+| `--paper-card` | Mixin applied to the card | `{}` |

+# Polymer Elements
+## Guide for Contributors
+
+Polymer Elements are built in the open, and the Polymer authors eagerly encourage any and all forms of community contribution. When contributing, please follow these guidelines:
+
+### Filing Issues
+
+**If you are filing an issue to request a feature**, please provide a clear description of the feature. It can be helpful to describe answers to the following questions:
+
+ 1. **Who will use the feature?** _“As someone filling out a form…”_
+ 2. **When will they use the feature?** _“When I enter an invalid value…”_
+ 3. **What is the user’s goal?** _“I want to be visually notified that the value needs to be corrected…”_
+
+**If you are filing an issue to report a bug**, please provide:
+
+ 1. **A clear description of the bug and related expectations.** Consider using the following example template for reporting a bug:
+
+ ```markdown
+ The `paper-foo` element causes the page to turn pink when clicked.
+
+ ## Expected outcome
+
+ The page stays the same color.
+
+ ## Actual outcome
+
+ The page turns pink.
+
+ ## Steps to reproduce
+
+ 1. Put a `paper-foo` element in the page.
+ 2. Open the page in a web browser.
+ 3. Click the `paper-foo` element.
+ ```
+
+ 2. **A reduced test case that demonstrates the problem.** If possible, please include the test case as a JSBin. Start with this template to easily import and use relevant Polymer Elements: [https://jsbin.com/cagaye/edit?html,output](https://jsbin.com/cagaye/edit?html,output).
+
+ 3. **A list of browsers where the problem occurs.** This can be skipped if the problem is the same across all browsers.
+
+### Submitting Pull Requests
+
+**Before creating a pull request**, please ensure that an issue exists for the corresponding change in the pull request that you intend to make. **If an issue does not exist, please create one per the guidelines above**. The goal is to discuss the design and necessity of the proposed change with Polymer authors and community before diving into a pull request.
+
+When submitting pull requests, please provide:
+
+ 1. **A reference to the corresponding issue** or issues that will be closed by the pull request. Please refer to these issues in the pull request description using the following syntax:
+
+ ```markdown
+ (For a single issue)
+ Fixes #20
+
+ (For multiple issues)
+ Fixes #32, fixes #40
+ ```
+
+ 2. **A succinct description of the design** used to fix any related issues. For example:
+
+ ```markdown
+ This fixes #20 by removing styles that leaked which would cause the page to turn pink whenever `paper-foo` is clicked.
+ ```
+
+ 3. **At least one test for each bug fixed or feature added** as part of the pull request. Pull requests that fix bugs or add features without accompanying tests will not be considered.
+
+If a proposed change contains multiple commits, please [squash commits](https://www.google.com/url?q=http://blog.steveklabnik.com/posts/2012-11-08-how-to-squash-commits-in-a-github-pull-request) to as few as is necessary to succinctly express the change. A Polymer author can help you squash commits, so don’t be afraid to ask us if you need help with that!

+[![Build status](https://travis-ci.org/PolymerElements/paper-checkbox.svg?branch=master)](https://travis-ci.org/PolymerElements/paper-checkbox)
+
+##&lt;paper-checkbox&gt;
+
+`paper-checkbox` is a [material design checkbox](https://www.google.com/design/spec/components/selection-controls.html#selection-controls-checkbox). 
+User can tap the checkbox to check or uncheck it. Usually you use checkboxes
+to allow user to select multiple options from a set. If you have a single
+ON/OFF option, avoid using a single checkbox and use `paper-toggle-button`
+instead.
+
+Example:

+Material design: [Checkbox](https://www.google.com/design/spec/components/selection-controls.html#selection-controls-checkbox)
+
+`paper-checkbox` is a button that can be either checked or unchecked.  User
+can tap the checkbox to check or uncheck it.  Usually you use checkboxes
+to allow user to select multiple options from a set.  If you have a single
+ON/OFF option, avoid using a single checkbox and use `paper-toggle-button`
+instead.
+
+Example:
+
+    <paper-checkbox>label</paper-checkbox>
+
+    <paper-checkbox checked> label</paper-checkbox>
+
+### Styling
+
+The following custom properties and mixins are available for styling:
+
+Custom property | Description | Default
+----------------|-------------|----------
+`--paper-checkbox-unchecked-background-color` | Checkbox background color when the input is not checked | `transparent`
+`--paper-checkbox-unchecked-color` | Checkbox border color when the input is not checked | `--primary-text-color`
+`--paper-checkbox-unchecked-ink-color` | Selected/focus ripple color when the input is not checked | `--primary-text-color`
+`--paper-checkbox-checked-color` | Checkbox color when the input is checked | `--primary-color`
+`--paper-checkbox-checked-ink-color` | Selected/focus ripple color when the input is checked | `--primary-color`
+`--paper-checkbox-checkmark-color` | Checkmark color | `white`
+`--paper-checkbox-label-color` | Label color | `--primary-text-color`
+`--paper-checkbox-label-checked-color` | Label color when the input is checked | `--paper-checkbox-label-color`
+`--paper-checkbox-label-spacing` | Spacing between the label and the checkbox | `8px`
+`--paper-checkbox-label` | Mixin applied to the label | `{}`
+`--paper-checkbox-label-checked` | Mixin applied to the label when the input is checked | `{}`
+`--paper-checkbox-error-color` | Checkbox color when invalid | `--error-color`
+`--paper-checkbox-size` | Size of the checkbox | `18px`
+`--paper-checkbox-ink-size` | Size of the ripple | `48px`
+`--paper-checkbox-margin` | Margin around the checkbox container | `initial`
+`--paper-checkbox-vertical-align` | Vertical alignment of the checkbox container | `middle`
+
+This element applies the mixin `--paper-font-common-base` but does not import `paper-styles/typography.html`.
+In order to apply the `Roboto` font to this element, make sure you've imported `paper-styles/typography.html`.

+# Polymer Elements
+## Guide for Contributors
+
+Polymer Elements are built in the open, and the Polymer authors eagerly encourage any and all forms of community contribution. When contributing, please follow these guidelines:
+
+### Filing Issues
+
+**If you are filing an issue to request a feature**, please provide a clear description of the feature. It can be helpful to describe answers to the following questions:
+
+ 1. **Who will use the feature?** _“As someone filling out a form…”_
+ 2. **When will they use the feature?** _“When I enter an invalid value…”_
+ 3. **What is the user’s goal?** _“I want to be visually notified that the value needs to be corrected…”_
+
+**If you are filing an issue to report a bug**, please provide:
+
+ 1. **A clear description of the bug and related expectations.** Consider using the following example template for reporting a bug:
+
+ ```markdown
+ The `paper-foo` element causes the page to turn pink when clicked.
+
+ ## Expected outcome
+
+ The page stays the same color.
+
+ ## Actual outcome
+
+ The page turns pink.
+
+ ## Steps to reproduce
+
+ 1. Put a `paper-foo` element in the page.
+ 2. Open the page in a web browser.
+ 3. Click the `paper-foo` element.
+ ```
+
+ 2. **A reduced test case that demonstrates the problem.** If possible, please include the test case as a JSBin. Start with this template to easily import and use relevant Polymer Elements: [https://jsbin.com/cagaye/edit?html,output](https://jsbin.com/cagaye/edit?html,output).
+
+ 3. **A list of browsers where the problem occurs.** This can be skipped if the problem is the same across all browsers.
+
+### Submitting Pull Requests
+
+**Before creating a pull request**, please ensure that an issue exists for the corresponding change in the pull request that you intend to make. **If an issue does not exist, please create one per the guidelines above**. The goal is to discuss the design and necessity of the proposed change with Polymer authors and community before diving into a pull request.
+
+When submitting pull requests, please provide:
+
+ 1. **A reference to the corresponding issue** or issues that will be closed by the pull request. Please refer to these issues in the pull request description using the following syntax:
+
+ ```markdown
+ (For a single issue)
+ Fixes #20
+
+ (For multiple issues)
+ Fixes #32, fixes #40
+ ```
+
+ 2. **A succinct description of the design** used to fix any related issues. For example:
+
+ ```markdown
+ This fixes #20 by removing styles that leaked which would cause the page to turn pink whenever `paper-foo` is clicked.
+ ```
+
+ 3. **At least one test for each bug fixed or feature added** as part of the pull request. Pull requests that fix bugs or add features without accompanying tests will not be considered.
+
+If a proposed change contains multiple commits, please [squash commits](https://www.google.com/url?q=http://blog.steveklabnik.com/posts/2012-11-08-how-to-squash-commits-in-a-github-pull-request) to as few as is necessary to succinctly express the change. A Polymer author can help you squash commits, so don’t be afraid to ask us if you need help with that!

+
+
+##Polymer.PaperDialogBehavior
+
+Use `Polymer.PaperDialogBehavior` and `paper-dialog-shared-styles.html` to implement a Material Design
+dialog.
+
+For example, if `<paper-dialog-impl>` implements this behavior:
+
+```html
+<paper-dialog-impl>
+    <h2>Header</h2>
+    <div>Dialog body</div>
+    <div class="buttons">
+        <paper-button dialog-dismiss>Cancel</paper-button>
+        <paper-button dialog-confirm>Accept</paper-button>
+    </div>
+</paper-dialog-impl>
+```
+
+`paper-dialog-shared-styles.html` provide styles for a header, content area, and an action area for buttons.
+Use the `<h2>` tag for the header and the `buttons` class for the action area. You can use the
+`paper-dialog-scrollable` element (in its own repository) if you need a scrolling content area.
+
+Use the `dialog-dismiss` and `dialog-confirm` attributes on interactive controls to close the
+dialog. If the user dismisses the dialog with `dialog-confirm`, the `closingReason` will update
+to include `confirmed: true`.
+
+### Accessibility
+
+This element has `role="dialog"` by default. Depending on the context, it may be more appropriate
+to override this attribute with `role="alertdialog"`.
+
+If `modal` is set, the element will prevent the focus from exiting the element.
+It will also ensure that focus remains in the dialog.

+
+`paper-dialog-shared-styles.html` provide styles for a header, content area, and an action area for buttons.
+Use the `<h2>` tag for the header and the `buttons` class for the action area. You can use the
+`paper-dialog-scrollable` element (in its own repository) if you need a scrolling content area.
+
+Use the `dialog-dismiss` and `dialog-confirm` attributes on interactive controls to close the
+dialog. If the user dismisses the dialog with `dialog-confirm`, the `closingReason` will update
+to include `confirmed: true`.
+
+### Accessibility
+
+This element has `role="dialog"` by default. Depending on the context, it may be more appropriate
+to override this attribute with `role="alertdialog"`.
+
+If `modal` is set, the element will prevent the focus from exiting the element.
+It will also ensure that focus remains in the dialog.

+ 2. **When will they use the feature?** _“When I enter an invalid value…”_
+ 3. **What is the user’s goal?** _“I want to be visually notified that the value needs to be corrected…”_
+
+**If you are filing an issue to report a bug**, please provide:
+
+ 1. **A clear description of the bug and related expectations.** Consider using the following example template for reporting a bug:
+
+ ```markdown
+ The `paper-foo` element causes the page to turn pink when clicked.
+
+ ## Expected outcome
+
+ The page stays the same color.
+
+ ## Actual outcome
+
+ The page turns pink.

+ 2. **A succinct description of the design** used to fix any related issues. For example:
+
+ ```markdown
+ This fixes #20 by removing styles that leaked which would cause the page to turn pink whenever `paper-foo` is clicked.
+ ```
+
+ 3. **At least one test for each bug fixed or feature added** as part of the pull request. Pull requests that fix bugs or add features without accompanying tests will not be considered.
+
+If a proposed change contains multiple commits, please [squash commits](https://www.google.com/url?q=http://blog.steveklabnik.com/posts/2012-11-08-how-to-squash-commits-in-a-github-pull-request) to as few as is necessary to succinctly express the change. A Polymer author can help you squash commits, so don’t be afraid to ask us if you need help with that!

+
+Material design: [Dialogs](https://www.google.com/design/spec/components/dialogs.html)
+
+`<paper-dialog>` is a dialog with Material Design styling and optional animations when it is
+opened or closed. It provides styles for a header, content area, and an action area for buttons.
+You can use the `<paper-dialog-scrollable>` element (in its own repository) if you need a scrolling
+content area. To autofocus a specific child element after opening the dialog, give it the `autofocus`
+attribute. See `Polymer.PaperDialogBehavior` and `Polymer.IronOverlayBehavior` for specifics.
+
+For example, the following code implements a dialog with a header, scrolling content area and
+buttons. Focus will be given to the `dialog-confirm` button when the dialog is opened.
+
+```html
+<paper-dialog>
+  <h2>Header</h2>
+  <paper-dialog-scrollable>
+    Lorem ipsum...
+  </paper-dialog-scrollable>
+  <div class="buttons">
+    <paper-button dialog-dismiss>Cancel</paper-button>
+    <paper-button dialog-confirm autofocus>Accept</paper-button>
+  </div>
+</paper-dialog>
+```
+
+### Styling
+
+See the docs for `Polymer.PaperDialogBehavior` for the custom properties available for styling
+this element.
+
+### Animations
+
+Set the `entry-animation` and/or `exit-animation` attributes to add an animation when the dialog
+is opened or closed. See the documentation in
+[PolymerElements/neon-animation](https://github.com/PolymerElements/neon-animation) for more info.
+
+For example:
+
+```html
+<link rel="import" href="components/neon-animation/animations/scale-up-animation.html">
+<link rel="import" href="components/neon-animation/animations/fade-out-animation.html">
+
+<paper-dialog entry-animation="scale-up-animation"
+              exit-animation="fade-out-animation">
+  <h2>Header</h2>
+  <div>Dialog body</div>
+</paper-dialog>
+```
+
+### Accessibility
+
+See the docs for `Polymer.PaperDialogBehavior` for accessibility features implemented by this
+element.

+Material design: [Dialogs](https://www.google.com/design/spec/components/dialogs.html)
+
+`<paper-dialog>` is a dialog with Material Design styling and optional animations when it is
+opened or closed. It provides styles for a header, content area, and an action area for buttons.
+You can use the `<paper-dialog-scrollable>` element (in its own repository) if you need a scrolling
+content area. To autofocus a specific child element after opening the dialog, give it the `autofocus`
+attribute. See `Polymer.PaperDialogBehavior` and `Polymer.IronOverlayBehavior` for specifics.
+
+For example, the following code implements a dialog with a header, scrolling content area and
+buttons. Focus will be given to the `dialog-confirm` button when the dialog is opened.
+
+    <paper-dialog>
+      <h2>Header</h2>
+      <paper-dialog-scrollable>
+        Lorem ipsum...
+      </paper-dialog-scrollable>
+      <div class="buttons">
+        <paper-button dialog-dismiss>Cancel</paper-button>
+        <paper-button dialog-confirm autofocus>Accept</paper-button>
+      </div>
+    </paper-dialog>
+
+### Styling
+
+See the docs for `Polymer.PaperDialogBehavior` for the custom properties available for styling
+this element.
+
+### Animations
+
+Set the `entry-animation` and/or `exit-animation` attributes to add an animation when the dialog
+is opened or closed. See the documentation in
+[PolymerElements/neon-animation](https://github.com/PolymerElements/neon-animation) for more info.
+
+For example:
+
+    <link rel="import" href="components/neon-animation/animations/scale-up-animation.html">
+    <link rel="import" href="components/neon-animation/animations/fade-out-animation.html">
+
+    <paper-dialog entry-animation="scale-up-animation"
+                  exit-animation="fade-out-animation">
+      <h2>Header</h2>
+      <div>Dialog body</div>
+    </paper-dialog>
+
+### Accessibility
+
+See the docs for `Polymer.PaperDialogBehavior` for accessibility features implemented by this
+element.

+# Polymer Elements
+## Guide for Contributors
+
+Polymer Elements are built in the open, and the Polymer authors eagerly encourage any and all forms of community contribution. When contributing, please follow these guidelines:
+
+### Filing Issues
+
+**If you are filing an issue to request a feature**, please provide a clear description of the feature. It can be helpful to describe answers to the following questions:
+
+ 1. **Who will use the feature?** _“As someone filling out a form…”_
+ 2. **When will they use the feature?** _“When I enter an invalid value…”_
+ 3. **What is the user’s goal?** _“I want to be visually notified that the value needs to be corrected…”_
+
+**If you are filing an issue to report a bug**, please provide:
+
+ 1. **A clear description of the bug and related expectations.** Consider using the following example template for reporting a bug:
+
+ ```markdown
+ The `paper-foo` element causes the page to turn pink when clicked.
+
+ ## Expected outcome
+
+ The page stays the same color.
+
+ ## Actual outcome
+
+ The page turns pink.
+
+ ## Steps to reproduce
+
+ 1. Put a `paper-foo` element in the page.
+ 2. Open the page in a web browser.
+ 3. Click the `paper-foo` element.
+ ```
+
+ 2. **A reduced test case that demonstrates the problem.** If possible, please include the test case as a JSBin. Start with this template to easily import and use relevant Polymer Elements: [https://jsbin.com/cagaye/edit?html,output](https://jsbin.com/cagaye/edit?html,output).
+
+ 3. **A list of browsers where the problem occurs.** This can be skipped if the problem is the same across all browsers.
+
+### Submitting Pull Requests
+
+**Before creating a pull request**, please ensure that an issue exists for the corresponding change in the pull request that you intend to make. **If an issue does not exist, please create one per the guidelines above**. The goal is to discuss the design and necessity of the proposed change with Polymer authors and community before diving into a pull request.
+
+When submitting pull requests, please provide:
+
+ 1. **A reference to the corresponding issue** or issues that will be closed by the pull request. Please refer to these issues in the pull request description using the following syntax:
+
+ ```markdown
+ (For a single issue)
+ Fixes #20
+
+ (For multiple issues)
+ Fixes #32, fixes #40
+ ```
+
+ 2. **A succinct description of the design** used to fix any related issues. For example:
+
+ ```markdown
+ This fixes #20 by removing styles that leaked which would cause the page to turn pink whenever `paper-foo` is clicked.
+ ```
+
+ 3. **At least one test for each bug fixed or feature added** as part of the pull request. Pull requests that fix bugs or add features without accompanying tests will not be considered.
+
+If a proposed change contains multiple commits, please [squash commits](https://www.google.com/url?q=http://blog.steveklabnik.com/posts/2012-11-08-how-to-squash-commits-in-a-github-pull-request) to as few as is necessary to succinctly express the change. A Polymer author can help you squash commits, so don’t be afraid to ask us if you need help with that!

+Material design: [Dropdown menus](https://www.google.com/design/spec/components/buttons.html#buttons-dropdown-buttons)
+
+This is a faster, lighter version of `paper-dropdown-menu`, that does not
+use a `<paper-input>` internally. Use this element if you're concerned about
+the performance of this element, i.e., if you plan on using many dropdowns on
+the same page. Note that this element has a slightly different styling API
+than `paper-dropdown-menu`.
+
+`paper-dropdown-menu-light` is similar to a native browser select element.
+`paper-dropdown-menu-light` works with selectable content. The currently selected
+item is displayed in the control. If no item is selected, the `label` is
+displayed instead.
+
+Example:
+
+    <paper-dropdown-menu-light label="Your favourite pastry">
+      <paper-listbox class="dropdown-content">
+        <paper-item>Croissant</paper-item>
+        <paper-item>Donut</paper-item>
+        <paper-item>Financier</paper-item>
+        <paper-item>Madeleine</paper-item>
+      </paper-listbox>
+    </paper-dropdown-menu-light>
+
+This example renders a dropdown menu with 4 options.
+
+The child element with the class `dropdown-content` is used as the dropdown
+menu. This can be a [`paper-listbox`](paper-listbox), or any other or
+element that acts like an [`iron-selector`](iron-selector).
+
+Specifically, the menu child must fire an
+[`iron-select`](iron-selector#event-iron-select) event when one of its
+children is selected, and an [`iron-deselect`](iron-selector#event-iron-deselect)
+event when a child is deselected. The selected or deselected item must
+be passed as the event's `detail.item` property.
+
+Applications can listen for the `iron-select` and `iron-deselect` events
+to react when options are selected and deselected.
+
+### Styling
+
+The following custom properties and mixins are also available for styling:
+
+Custom property | Description | Default
+----------------|-------------|----------
+`--paper-dropdown-menu` | A mixin that is applied to the element host | `{}`
+`--paper-dropdown-menu-disabled` | A mixin that is applied to the element host when disabled | `{}`
+`--paper-dropdown-menu-ripple` | A mixin that is applied to the internal ripple | `{}`
+`--paper-dropdown-menu-button` | A mixin that is applied to the internal menu button | `{}`
+`--paper-dropdown-menu-icon` | A mixin that is applied to the internal icon | `{}`
+`--paper-dropdown-menu-disabled-opacity` | The opacity of the dropdown when disabled  | `0.33`
+`--paper-dropdown-menu-color` | The color of the input/label/underline when the dropdown is unfocused | `--primary-text-color`
+`--paper-dropdown-menu-focus-color` | The color of the label/underline when the dropdown is focused  | `--primary-color`
+`--paper-dropdown-error-color` | The color of the label/underline when the dropdown is invalid  | `--error-color`
+`--paper-dropdown-menu-label` | Mixin applied to the label | `{}`
+`--paper-dropdown-menu-input` | Mixin appled to the input | `{}`
+
+Note that in this element, the underline is just the bottom border of the "input".
+To style it:
+
+    <style is=custom-style>
+      paper-dropdown-menu-light.custom {
+        --paper-dropdown-menu-input: {
+          border-bottom: 2px dashed lavender;

+Material design: [Dropdown menus](https://www.google.com/design/spec/components/buttons.html#buttons-dropdown-buttons)
+
+`paper-dropdown-menu` is similar to a native browser select element.
+`paper-dropdown-menu` works with selectable content. The currently selected
+item is displayed in the control. If no item is selected, the `label` is
+displayed instead.
+
+Example:
+
+    <paper-dropdown-menu label="Your favourite pastry">
+      <paper-listbox class="dropdown-content">
+        <paper-item>Croissant</paper-item>
+        <paper-item>Donut</paper-item>
+        <paper-item>Financier</paper-item>
+        <paper-item>Madeleine</paper-item>
+      </paper-listbox>
+    </paper-dropdown-menu>
+
+This example renders a dropdown menu with 4 options.
+
+The child element with the class `dropdown-content` is used as the dropdown
+menu. This can be a [`paper-listbox`](paper-listbox), or any other or
+element that acts like an [`iron-selector`](iron-selector).
+
+Specifically, the menu child must fire an
+[`iron-select`](iron-selector#event-iron-select) event when one of its
+children is selected, and an [`iron-deselect`](iron-selector#event-iron-deselect)
+event when a child is deselected. The selected or deselected item must
+be passed as the event's `detail.item` property.
+
+Applications can listen for the `iron-select` and `iron-deselect` events
+to react when options are selected and deselected.
+
+### Styling
+
+The following custom properties and mixins are also available for styling:
+
+Custom property | Description | Default
+----------------|-------------|----------
+`--paper-dropdown-menu` | A mixin that is applied to the element host | `{}`
+`--paper-dropdown-menu-disabled` | A mixin that is applied to the element host when disabled | `{}`
+`--paper-dropdown-menu-ripple` | A mixin that is applied to the internal ripple | `{}`
+`--paper-dropdown-menu-button` | A mixin that is applied to the internal menu button | `{}`
+`--paper-dropdown-menu-input` | A mixin that is applied to the internal paper input | `{}`
+`--paper-dropdown-menu-icon` | A mixin that is applied to the internal icon | `{}`
+
+You can also use any of the `paper-input-container` and `paper-menu-button`
+style mixins and custom properties to style the internal input and menu button
+respectively.

+# Polymer Elements
+## Guide for Contributors
+
+Polymer Elements are built in the open, and the Polymer authors eagerly encourage any and all forms of community contribution. When contributing, please follow these guidelines:
+
+### Filing Issues
+
+**If you are filing an issue to request a feature**, please provide a clear description of the feature. It can be helpful to describe answers to the following questions:
+
+ 1. **Who will use the feature?** _“As someone filling out a form…”_
+ 2. **When will they use the feature?** _“When I enter an invalid value…”_
+ 3. **What is the user’s goal?** _“I want to be visually notified that the value needs to be corrected…”_
+
+**If you are filing an issue to report a bug**, please provide:
+
+ 1. **A clear description of the bug and related expectations.** Consider using the following example template for reporting a bug:
+
+ ```markdown
+ The `paper-foo` element causes the page to turn pink when clicked.
+
+ ## Expected outcome
+
+ The page stays the same color.
+
+ ## Actual outcome
+
+ The page turns pink.
+
+ ## Steps to reproduce
+
+ 1. Put a `paper-foo` element in the page.
+ 2. Open the page in a web browser.
+ 3. Click the `paper-foo` element.
+ ```
+
+ 2. **A reduced test case that demonstrates the problem.** If possible, please include the test case as a JSBin. Start with this template to easily import and use relevant Polymer Elements: [https://jsbin.com/cagaye/edit?html,output](https://jsbin.com/cagaye/edit?html,output).
+
+ 3. **A list of browsers where the problem occurs.** This can be skipped if the problem is the same across all browsers.
+
+### Submitting Pull Requests
+
+**Before creating a pull request**, please ensure that an issue exists for the corresponding change in the pull request that you intend to make. **If an issue does not exist, please create one per the guidelines above**. The goal is to discuss the design and necessity of the proposed change with Polymer authors and community before diving into a pull request.
+
+When submitting pull requests, please provide:
+
+ 1. **A reference to the corresponding issue** or issues that will be closed by the pull request. Please refer to these issues in the pull request description using the following syntax:
+
+ ```markdown
+ (For a single issue)
+ Fixes #20
+
+ (For multiple issues)
+ Fixes #32, fixes #40
+ ```
+
+ 2. **A succinct description of the design** used to fix any related issues. For example:
+
+ ```markdown
+ This fixes #20 by removing styles that leaked which would cause the page to turn pink whenever `paper-foo` is clicked.
+ ```
+
+ 3. **At least one test for each bug fixed or feature added** as part of the pull request. Pull requests that fix bugs or add features without accompanying tests will not be considered.
+
+If a proposed change contains multiple commits, please [squash commits](https://www.google.com/url?q=http://blog.steveklabnik.com/posts/2012-11-08-how-to-squash-commits-in-a-github-pull-request) to as few as is necessary to succinctly express the change. A Polymer author can help you squash commits, so don’t be afraid to ask us if you need help with that!

+##&lt;paper-fab&gt;
+
+Material design: [Floating Action Button](https://www.google.com/design/spec/components/buttons-floating-action-button.html)
+
+`paper-fab` is a floating action button. It contains an image placed in the center and
+comes in two sizes: regular size and a smaller size by applying the attribute `mini`. When
+the user touches the button, a ripple effect emanates from the center of the button.
+
+You may import `iron-icons` to use with this element, or provide a URL to a custom icon.
+See `iron-iconset` for more information about how to use a custom icon set.

+Material design: [Floating Action Button](https://www.google.com/design/spec/components/buttons-floating-action-button.html)
+
+`paper-fab` is a floating action button. It contains an image placed in the center and
+comes in two sizes: regular size and a smaller size by applying the attribute `mini`. When
+the user touches the button, a ripple effect emanates from the center of the button.
+
+You may import `iron-icons` to use with this element, or provide a URL to a custom icon.
+See `iron-iconset` for more information about how to use a custom icon set.
+
+Example:
+
+    <link href="path/to/iron-icons/iron-icons.html" rel="import">
+
+    <paper-fab icon="add"></paper-fab>
+    <paper-fab mini icon="favorite"></paper-fab>
+    <paper-fab src="star.png"></paper-fab>
+
+
+### Styling
+
+The following custom properties and mixins are available for styling:
+
+Custom property | Description | Default
+----------------|-------------|----------
+`--paper-fab-background` | The background color of the button | `--accent-color`
+`--paper-fab-keyboard-focus-background` | The background color of the button when focused | `--paper-pink-900`
+`--paper-fab-disabled-background` | The background color of the button when it's disabled | `--paper-grey-300`
+`--paper-fab-disabled-text` | The text color of the button when it's disabled | `--paper-grey-500`
+`--paper-fab` | Mixin applied to the button | `{}`
+`--paper-fab-mini` | Mixin applied to a mini button | `{}`
+`--paper-fab-disabled` | Mixin applied to a disabled button | `{}`
+`--paper-fab-iron-icon` | Mixin applied to the iron-icon within the button | `{}`
+`--paper-fab-label` | Mixin applied to the label within the button | `{}`

+# Polymer Elements
+## Guide for Contributors
+
+Polymer Elements are built in the open, and the Polymer authors eagerly encourage any and all forms of community contribution. When contributing, please follow these guidelines:
+
+### Filing Issues
+
+**If you are filing an issue to request a feature**, please provide a clear description of the feature. It can be helpful to describe answers to the following questions:
+
+ 1. **Who will use the feature?** _“As someone filling out a form…”_
+ 2. **When will they use the feature?** _“When I enter an invalid value…”_
+ 3. **What is the user’s goal?** _“I want to be visually notified that the value needs to be corrected…”_
+
+**If you are filing an issue to report a bug**, please provide:
+
+ 1. **A clear description of the bug and related expectations.** Consider using the following example template for reporting a bug:
+
+ ```markdown
+ The `paper-foo` element causes the page to turn pink when clicked.
+
+ ## Expected outcome
+
+ The page stays the same color.
+
+ ## Actual outcome
+
+ The page turns pink.
+
+ ## Steps to reproduce
+
+ 1. Put a `paper-foo` element in the page.
+ 2. Open the page in a web browser.
+ 3. Click the `paper-foo` element.
+ ```
+
+ 2. **A reduced test case that demonstrates the problem.** If possible, please include the test case as a JSBin. Start with this template to easily import and use relevant Polymer Elements: [https://jsbin.com/cagaye/edit?html,output](https://jsbin.com/cagaye/edit?html,output).
+
+ 3. **A list of browsers where the problem occurs.** This can be skipped if the problem is the same across all browsers.
+
+### Submitting Pull Requests
+
+**Before creating a pull request**, please ensure that an issue exists for the corresponding change in the pull request that you intend to make. **If an issue does not exist, please create one per the guidelines above**. The goal is to discuss the design and necessity of the proposed change with Polymer authors and community before diving into a pull request.
+
+When submitting pull requests, please provide:
+
+ 1. **A reference to the corresponding issue** or issues that will be closed by the pull request. Please refer to these issues in the pull request description using the following syntax:
+
+ ```markdown
+ (For a single issue)
+ Fixes #20
+
+ (For multiple issues)
+ Fixes #32, fixes #40
+ ```
+
+ 2. **A succinct description of the design** used to fix any related issues. For example:
+
+ ```markdown
+ This fixes #20 by removing styles that leaked which would cause the page to turn pink whenever `paper-foo` is clicked.
+ ```
+
+ 3. **At least one test for each bug fixed or feature added** as part of the pull request. Pull requests that fix bugs or add features without accompanying tests will not be considered.
+
+If a proposed change contains multiple commits, please [squash commits](https://www.google.com/url?q=http://blog.steveklabnik.com/posts/2012-11-08-how-to-squash-commits-in-a-github-pull-request) to as few as is necessary to succinctly express the change. A Polymer author can help you squash commits, so don’t be afraid to ask us if you need help with that!

+
+
+##&lt;paper-icon-button&gt;
+
+Material design: [Icon toggles](https://www.google.com/design/spec/components/buttons.html#buttons-toggle-buttons)
+
+`paper-icon-button` is a button with an image placed at the center. When the user touches
+the button, a ripple effect emanates from the center of the button.
+
+`paper-icon-button` includes a default icon set.  Use `icon` to specify which icon
+from the icon set to use.
+
+<!---
+```html
+<custom-element-demo>
+  <template>
+    <script src="../webcomponentsjs/webcomponents-lite.js"></script>
+    <link rel="import" href="paper-icon-button.html">
+    <link rel="import" href="../iron-icons/iron-icons.html">
+    <next-code-block></next-code-block>
+  </template>
+</custom-element-demo>
+```
+-->
+```html
+<paper-icon-button icon="favorite"></paper-icon-button>
+<paper-icon-button icon="menu"></paper-icon-button>
+<paper-icon-button icon="star"></paper-icon-button>
+```
+
+See [`iron-iconset`](https://github.com/PolymerElements/iron-iconset) for more information about
+how to use a custom icon set.
+
+Example:
+
+```html
+<link href="path/to/iron-icons/iron-icons.html" rel="import">
+
+<paper-icon-button icon="favorite"></paper-icon-button>
+<paper-icon-button src="star.png"></paper-icon-button>
+```
+
+To use `paper-icon-button` as a link, wrap it in an anchor tag. Since `paper-icon-button`
+will already receive focus, you may want to prevent the anchor tag from receiving focus
+as well by setting its tabindex to -1.
+
+```html
+<a href="https://www.polymer-project.org" tabindex="-1">
+  <paper-icon-button icon="polymer"></paper-icon-button>
+</a>
+```
+
+### Styling
+
+Style the button with CSS as you would a normal DOM element. If you are using the icons
+provided by `iron-icons`, they will inherit the foreground color of the button.
+
+```html
+/* make a red "favorite" button */
+<paper-icon-button icon="favorite" style="color: red;"></paper-icon-button>
+```
+
+By default, the ripple is the same color as the foreground at 25% opacity. You may
+customize the color using the `--paper-icon-button-ink-color` custom property.
+
+The following custom properties and mixins are available for styling:
+
+| Custom property | Description | Default |
+| --- | --- | --- |
+| `--paper-icon-button-disabled-text` | The color of the disabled button | `--disabled-text-color` |
+| `--paper-icon-button-ink-color` | Selected/focus ripple color | `--primary-text-color` |
+| `--paper-icon-button` | Mixin for a button | `{}` |
+| `--paper-icon-button-disabled` | Mixin for a disabled button | `{}` |
+| `--paper-icon-button-hover` | Mixin for button on hover | `{}` |
+

+Material design: [Icon toggles](https://www.google.com/design/spec/components/buttons.html#buttons-toggle-buttons)
+
+`paper-icon-button` is a button with an image placed at the center. When the user touches
+the button, a ripple effect emanates from the center of the button.
+
+`paper-icon-button` includes a default icon set.  Use `icon` to specify which icon
+from the icon set to use.
+
+    <paper-icon-button icon="menu"></paper-icon-button>
+
+See [`iron-iconset`](iron-iconset) for more information about
+how to use a custom icon set.
+
+Example:
+
+    <link href="path/to/iron-icons/iron-icons.html" rel="import">
+
+    <paper-icon-button icon="favorite"></paper-icon-button>
+    <paper-icon-button src="star.png"></paper-icon-button>
+
+To use `paper-icon-button` as a link, wrap it in an anchor tag. Since `paper-icon-button`
+will already receive focus, you may want to prevent the anchor tag from receiving focus
+as well by setting its tabindex to -1.
+
+    <a href="https://www.polymer-project.org" tabindex="-1">
+      <paper-icon-button icon="polymer"></paper-icon-button>
+    </a>
+
+### Styling
+
+Style the button with CSS as you would a normal DOM element. If you are using the icons
+provided by `iron-icons`, they will inherit the foreground color of the button.
+
+    /* make a red "favorite" button */
+    <paper-icon-button icon="favorite" style="color: red;"></paper-icon-button>
+
+By default, the ripple is the same color as the foreground at 25% opacity. You may
+customize the color using the `--paper-icon-button-ink-color` custom property.
+
+The following custom properties and mixins are available for styling:
+
+Custom property | Description | Default
+----------------|-------------|----------
+`--paper-icon-button-disabled-text` | The color of the disabled button | `--disabled-text-color`
+`--paper-icon-button-ink-color` | Selected/focus ripple color | `--primary-text-color`
+`--paper-icon-button` | Mixin for a button | `{}`
+`--paper-icon-button-disabled` | Mixin for a disabled button | `{}`
+`--paper-icon-button-hover` | Mixin for button on hover | `{}`

+# Polymer Elements
+## Guide for Contributors
+
+Polymer Elements are built in the open, and the Polymer authors eagerly encourage any and all forms of community contribution. When contributing, please follow these guidelines:
+
+### Filing Issues
+
+**If you are filing an issue to request a feature**, please provide a clear description of the feature. It can be helpful to describe answers to the following questions:
+
+ 1. **Who will use the feature?** _“As someone filling out a form…”_
+ 2. **When will they use the feature?** _“When I enter an invalid value…”_
+ 3. **What is the user’s goal?** _“I want to be visually notified that the value needs to be corrected…”_
+
+**If you are filing an issue to report a bug**, please provide:
+
+ 1. **A clear description of the bug and related expectations.** Consider using the following example template for reporting a bug:
+
+ ```markdown
+ The `paper-foo` element causes the page to turn pink when clicked.
+
+ ## Expected outcome
+
+ The page stays the same color.
+
+ ## Actual outcome
+
+ The page turns pink.
+
+ ## Steps to reproduce
+
+ 1. Put a `paper-foo` element in the page.
+ 2. Open the page in a web browser.
+ 3. Click the `paper-foo` element.
+ ```
+
+ 2. **A reduced test case that demonstrates the problem.** If possible, please include the test case as a JSBin. Start with this template to easily import and use relevant Polymer Elements: [https://jsbin.com/cagaye/edit?html,output](https://jsbin.com/cagaye/edit?html,output).
+
+ 3. **A list of browsers where the problem occurs.** This can be skipped if the problem is the same across all browsers.
+
+### Submitting Pull Requests
+
+**Before creating a pull request**, please ensure that an issue exists for the corresponding change in the pull request that you intend to make. **If an issue does not exist, please create one per the guidelines above**. The goal is to discuss the design and necessity of the proposed change with Polymer authors and community before diving into a pull request.
+
+When submitting pull requests, please provide:
+
+ 1. **A reference to the corresponding issue** or issues that will be closed by the pull request. Please refer to these issues in the pull request description using the following syntax:
+
+ ```markdown
+ (For a single issue)
+ Fixes #20
+
+ (For multiple issues)
+ Fixes #32, fixes #40
+ ```
+
+ 2. **A succinct description of the design** used to fix any related issues. For example:
+
+ ```markdown
+ This fixes #20 by removing styles that leaked which would cause the page to turn pink whenever `paper-foo` is clicked.
+ ```
+
+ 3. **At least one test for each bug fixed or feature added** as part of the pull request. Pull requests that fix bugs or add features without accompanying tests will not be considered.
+
+If a proposed change contains multiple commits, please [squash commits](https://www.google.com/url?q=http://blog.steveklabnik.com/posts/2012-11-08-how-to-squash-commits-in-a-github-pull-request) to as few as is necessary to succinctly express the change. A Polymer author can help you squash commits, so don’t be afraid to ask us if you need help with that!

+`<paper-input-container>` is a container for a `<label>`, an `<input is="iron-input">` or
+`<textarea>` and optional add-on elements such as an error message or character
+counter, used to implement Material Design text fields.
+
+For example:
+
+    <paper-input-container>
+      <label>Your name</label>
+      <input is="iron-input">
+    </paper-input-container>
+
+Do not wrap `<paper-input-container>` around elements that already include it, such as `<paper-input>`.
+Doing so may cause events to bounce infintely between the container and its contained element.
+
+### Listening for input changes
+
+By default, it listens for changes on the `bind-value` attribute on its children nodes and perform
+tasks such as auto-validating and label styling when the `bind-value` changes. You can configure
+the attribute it listens to with the `attr-for-value` attribute.
+
+### Using a custom input element
+
+You can use a custom input element in a `<paper-input-container>`, for example to implement a
+compound input field like a social security number input. The custom input element should have the
+`paper-input-input` class, have a `notify:true` value property and optionally implements
+`Polymer.IronValidatableBehavior` if it is validatable.
+
+    <paper-input-container attr-for-value="ssn-value">
+      <label>Social security number</label>
+      <ssn-input class="paper-input-input"></ssn-input>
+    </paper-input-container>
+
+
+If you're using a `<paper-input-container>` imperatively, it's important to make sure
+that you attach its children (the `iron-input` and the optional `label`) before you
+attach the `<paper-input-container>` itself, so that it can be set up correctly.
+
+### Validation
+
+If the `auto-validate` attribute is set, the input container will validate the input and update
+the container styling when the input value changes.
+
+### Add-ons
+
+Add-ons are child elements of a `<paper-input-container>` with the `add-on` attribute and
+implements the `Polymer.PaperInputAddonBehavior` behavior. They are notified when the input value
+or validity changes, and may implement functionality such as error messages or character counters.
+They appear at the bottom of the input.
+
+### Prefixes and suffixes
+These are child elements of a `<paper-input-container>` with the `prefix`
+or `suffix` attribute, and are displayed inline with the input, before or after.
+
+    <paper-input-container>
+      <div prefix>$</div>
+      <label>Total</label>
+      <input is="iron-input">
+      <paper-icon-button suffix icon="clear"></paper-icon-button>
+    </paper-input-container>
+
+### Styling
+
+The following custom properties and mixins are available for styling:
+
+Custom property | Description | Default
+----------------|-------------|----------
+`--paper-input-container-color` | Label and underline color when the input is not focused | `--secondary-text-color`

+`--paper-input-container-invalid-color` | Label and underline color when the input is is invalid | `--error-color`
+`--paper-input-container-input-color` | Input foreground color | `--primary-text-color`
+`--paper-input-container` | Mixin applied to the container | `{}`
+`--paper-input-container-disabled` | Mixin applied to the container when it's disabled | `{}`
+`--paper-input-container-label` | Mixin applied to the label | `{}`
+`--paper-input-container-label-focus` | Mixin applied to the label when the input is focused | `{}`
+`--paper-input-container-label-floating` | Mixin applied to the label when floating | `{}`

+`--paper-input-container-input-focus` | Mixin applied to the input when focused | `{}`
+`--paper-input-container-input-invalid` | Mixin applied to the input when invalid | `{}`
+`--paper-input-container-input-webkit-spinner` | Mixin applied to the webkit spinner | `{}`
+`--paper-input-container-input-webkit-clear` | Mixin applied to the webkit clear button | `{}`
+`--paper-input-container-ms-clear` | Mixin applied to the Internet Explorer clear button | `{}`
+`--paper-input-container-underline` | Mixin applied to the underline | `{}`
+`--paper-input-container-underline-focus` | Mixin applied to the underline when the input is focused | `{}`
+`--paper-input-container-underline-disabled` | Mixin applied to the underline when the input is disabled | `{}`
+`--paper-input-prefix` | Mixin applied to the input prefix | `{}`
+`--paper-input-suffix` | Mixin applied to the input suffix | `{}`
+
+This element is `display:block` by default, but you can set the `inline` attribute to make it
+`display:inline-block`.

+Material design: [Text fields](https://www.google.com/design/spec/components/text-fields.html)
+
+`<paper-input>` is a single-line text field with Material Design styling.
+
+    <paper-input label="Input label"></paper-input>
+
+It may include an optional error message or character counter.
+
+    <paper-input error-message="Invalid input!" label="Input label"></paper-input>
+    <paper-input char-counter label="Input label"></paper-input>
+
+It can also include custom prefix or suffix elements, which are displayed
+before or after the text input itself. In order for an element to be
+considered as a prefix, it must have the `prefix` attribute (and similarly
+for `suffix`).
+
+    <paper-input label="total">
+      <div prefix>$</div>
+      <paper-icon-button suffix icon="clear"></paper-icon-button>
+    </paper-input>
+
+A `paper-input` can use the native `type=search` or `type=file` features.
+However, since we can't control the native styling of the input (search icon,
+file button, date placeholder, etc.), in these cases the label will be
+automatically floated. The `placeholder` attribute can still be used for
+additional informational text.
+
+    <paper-input label="search!" type="search"
+        placeholder="search for cats" autosave="test" results="5">
+    </paper-input>
+
+See `Polymer.PaperInputBehavior` for more API docs.
+
+### Focus
+
+To focus a paper-input, you can call the native `focus()` method as long as the
+paper input has a tab index.
+
+### Styling
+
+See `Polymer.PaperInputContainer` for a list of custom properties used to
+style this element.

+# Polymer Elements
+## Guide for Contributors
+
+Polymer Elements are built in the open, and the Polymer authors eagerly encourage any and all forms of community contribution. When contributing, please follow these guidelines:
+
+### Filing Issues
+
+**If you are filing an issue to request a feature**, please provide a clear description of the feature. It can be helpful to describe answers to the following questions:
+
+ 1. **Who will use the feature?** _“As someone filling out a form…”_
+ 2. **When will they use the feature?** _“When I enter an invalid value…”_
+ 3. **What is the user’s goal?** _“I want to be visually notified that the value needs to be corrected…”_
+
+**If you are filing an issue to report a bug**, please provide:
+
+ 1. **A clear description of the bug and related expectations.** Consider using the following example template for reporting a bug:
+
+ ```markdown
+ The `paper-foo` element causes the page to turn pink when clicked.
+
+ ## Expected outcome
+
+ The page stays the same color.
+
+ ## Actual outcome
+
+ The page turns pink.
+
+ ## Steps to reproduce
+
+ 1. Put a `paper-foo` element in the page.
+ 2. Open the page in a web browser.
+ 3. Click the `paper-foo` element.
+ ```
+
+ 2. **A reduced test case that demonstrates the problem.** If possible, please include the test case as a JSBin. Start with this template to easily import and use relevant Polymer Elements: [https://jsbin.com/cagaye/edit?html,output](https://jsbin.com/cagaye/edit?html,output).
+
+ 3. **A list of browsers where the problem occurs.** This can be skipped if the problem is the same across all browsers.
+
+### Submitting Pull Requests
+
+**Before creating a pull request**, please ensure that an issue exists for the corresponding change in the pull request that you intend to make. **If an issue does not exist, please create one per the guidelines above**. The goal is to discuss the design and necessity of the proposed change with Polymer authors and community before diving into a pull request.
+
+When submitting pull requests, please provide:
+
+ 1. **A reference to the corresponding issue** or issues that will be closed by the pull request. Please refer to these issues in the pull request description using the following syntax:
+
+ ```markdown
+ (For a single issue)
+ Fixes #20
+
+ (For multiple issues)
+ Fixes #32, fixes #40
+ ```
+
+ 2. **A succinct description of the design** used to fix any related issues. For example:
+
+ ```markdown
+ This fixes #20 by removing styles that leaked which would cause the page to turn pink whenever `paper-foo` is clicked.
+ ```
+
+ 3. **At least one test for each bug fixed or feature added** as part of the pull request. Pull requests that fix bugs or add features without accompanying tests will not be considered.
+
+If a proposed change contains multiple commits, please [squash commits](https://www.google.com/url?q=http://blog.steveklabnik.com/posts/2012-11-08-how-to-squash-commits-in-a-github-pull-request) to as few as is necessary to succinctly express the change. A Polymer author can help you squash commits, so don’t be afraid to ask us if you need help with that!

+[![Build status](https://travis-ci.org/PolymerElements/paper-item.svg?branch=master)](https://travis-ci.org/PolymerElements/paper-item)
+
+_[Demo and API docs](https://elements.polymer-project.org/elements/paper-item)_
+
+
+##&lt;paper-item&gt;
+
+Material design: [Lists](https://www.google.com/design/spec/components/lists.html)
+
+`<paper-item>` is an interactive list item. By default, it is a horizontal flexbox.
+
+```html
+<paper-item>Item</paper-item>
+```
+
+Use this element with `<paper-item-body>` to make Material Design styled two-line and three-line
+items.
+
+```html
+<paper-item>
+  <paper-item-body two-line>
+    <div>Show your status</div>
+    <div secondary>Your status is visible to everyone</div>
+  </paper-item-body>
+  <iron-icon icon="warning"></iron-icon>
+</paper-item>
+```
+
+To use `paper-item` as a link, wrap it in an anchor tag. Since `paper-item` will
+already receive focus, you may want to prevent the anchor tag from receiving
+focus as well by setting its tabindex to -1.
+
+```html
+<a href="https://www.polymer-project.org/" tabindex="-1">
+  <paper-item raised>Polymer Project</paper-item>
+</a>
+```
+
+If you are concerned about performance and want to use `paper-item` in a `paper-listbox`
+with many items, you can just use a native `button` with the `paper-item` class
+applied (provided you have correctly included the shared styles):
+
+```html
+<style is="custom-style" include="paper-item-shared-styles"></style>
+
+<paper-listbox>
+  <button class="paper-item" role="option">Inbox</button>
+  <button class="paper-item" role="option">Starred</button>
+  <button class="paper-item" role="option">Sent mail</button>
+</paper-listbox>
+```
+
+### Styling
+
+The following custom properties and mixins are available for styling:
+
+| Custom property | Description | Default |
+| --- | --- | --- |
+| `--paper-item-min-height` | Minimum height of the item | `48px` |
+| `--paper-item` | Mixin applied to the item | `{}` |
+| `--paper-item-selected-weight` | The font weight of a selected item | `bold` |
+| `--paper-item-selected` | Mixin applied to selected paper-items | `{}` |
+| `--paper-item-disabled-color` | The color for disabled paper-items | `--disabled-text-color` |
+| `--paper-item-disabled` | Mixin applied to disabled paper-items | `{}` |
+| `--paper-item-focused` | Mixin applied to focused paper-items | `{}` |
+| `--paper-item-focused-before` | Mixin applied to :before focused paper-items | `{}` |
+
+### Accessibility
+
+This element has `role="listitem"` by default. Depending on usage, it may be more appropriate to set
+`role="menuitem"`, `role="menuitemcheckbox"` or `role="menuitemradio"`.
+
+```html
+<paper-item role="menuitemcheckbox">
+  <paper-item-body>
+    Show your status
+  </paper-item-body>
+  <paper-checkbox></paper-checkbox>
+</paper-item>
+```
+
+
+
+##&lt;paper-icon-item&gt;
+
+`<paper-icon-item>` is a convenience element to make an item with icon. It is an interactive list
+item with a fixed-width icon area, according to Material Design. This is useful if the icons are of
+varying widths, but you want the item bodies to line up. Use this like a `<paper-item>`. The child
+node with the attribute `item-icon` is placed in the icon area.
+
+```html
+<paper-icon-item>
+  <iron-icon icon="favorite" item-icon></iron-icon>
+  Favorite
+</paper-icon-item>
+<paper-icon-item>
+  <div class="avatar" item-icon></div>
+  Avatar
+</paper-icon-item>
+```
+
+### Styling
+
+The following custom properties and mixins are available for styling:
+
+| Custom property | Description | Default |
+| --- | --- | --- |
+| `--paper-item-icon-width` | Width of the icon area | `56px` |
+| `--paper-item-icon` | Mixin applied to the icon area | `{}` |
+| `--paper-icon-item` | Mixin applied to the item | `{}` |
+| `--paper-item-selected-weight` | The font weight of a selected item | `bold` |
+| `--paper-item-selected` | Mixin applied to selected paper-items | `{}` |
+| `--paper-item-disabled-color` | The color for disabled paper-items | `--disabled-text-color` |
+| `--paper-item-disabled` | Mixin applied to disabled paper-items | `{}` |
+| `--paper-item-focused` | Mixin applied to focused paper-items | `{}` |
+| `--paper-item-focused-before` | Mixin applied to :before focused paper-items | `{}` |
+
+
+
+##&lt;paper-item-body&gt;
+
+Use `<paper-item-body>` in a `<paper-item>` or `<paper-icon-item>` to make two- or
+three- line items. It is a flex item that is a vertical flexbox.
+
+```html
+<paper-item>
+  <paper-item-body two-line>
+    <div>Show your status</div>
+    <div secondary>Your status is visible to everyone</div>
+  </paper-item-body>
+</paper-item>
+```
+
+The child elements with the `secondary` attribute is given secondary text styling.
+
+### Styling
+
+The following custom properties and mixins are available for styling:
+
+| Custom property | Description | Default |
+| --- | --- | --- |
+| `--paper-item-body-two-line-min-height` | Minimum height of a two-line item | `72px` |
+| `--paper-item-body-three-line-min-height` | Minimum height of a three-line item | `88px` |
+| `--paper-item-body-secondary-color` | Foreground color for the `secondary` area | `--secondary-text-color` |
+| `--paper-item-body-secondary` | Mixin applied to the `secondary` area | `{}` |

+`<paper-icon-item>` is a convenience element to make an item with icon. It is an interactive list
+item with a fixed-width icon area, according to Material Design. This is useful if the icons are of
+varying widths, but you want the item bodies to line up. Use this like a `<paper-item>`. The child
+node with the attribute `item-icon` is placed in the icon area.

+Material design: [Lists](https://www.google.com/design/spec/components/lists.html)
+
+`<paper-item>` is an interactive list item. By default, it is a horizontal flexbox.
+
+    <paper-item>Item</paper-item>
+
+Use this element with `<paper-item-body>` to make Material Design styled two-line and three-line
+items.
+
+    <paper-item>
+      <paper-item-body two-line>
+        <div>Show your status</div>

+      </paper-item-body>
+      <iron-icon icon="warning"></iron-icon>
+    </paper-item>
+
+To use `paper-item` as a link, wrap it in an anchor tag. Since `paper-item` will
+already receive focus, you may want to prevent the anchor tag from receiving
+focus as well by setting its tabindex to -1.
+
+    <a href="https://www.polymer-project.org/" tabindex="-1">
+      <paper-item raised>Polymer Project</paper-item>
+    </a>
+
+If you are concerned about performance and want to use `paper-item` in a `paper-listbox`
+with many items, you can just use a native `button` with the `paper-item` class
+applied (provided you have correctly included the shared styles):
+
+    <style is="custom-style" include="paper-item-shared-styles"></style>
+
+    <paper-listbox>
+      <button class="paper-item" role="option">Inbox</button>
+      <button class="paper-item" role="option">Starred</button>
+      <button class="paper-item" role="option">Sent mail</button>
+    </paper-listbox>
+
+### Styling
+
+The following custom properties and mixins are available for styling:
+

+`--paper-item-selected-weight`| The font weight of a selected item           | `bold`
+`--paper-item-selected`       | Mixin applied to selected paper-items        | `{}`
+`--paper-item-disabled-color` | The color for disabled paper-items           | `--disabled-text-color`
+`--paper-item-disabled`       | Mixin applied to disabled paper-items        | `{}`
+`--paper-item-focused`        | Mixin applied to focused paper-items         | `{}`
+`--paper-item-focused-before` | Mixin applied to :before focused paper-items | `{}`
+
+### Accessibility
+
+This element has `role="listitem"` by default. Depending on usage, it may be more appropriate to set
+`role="menuitem"`, `role="menuitemcheckbox"` or `role="menuitemradio"`.
+
+    <paper-item role="menuitemcheckbox">

+# Polymer Elements
+## Guide for Contributors
+
+Polymer Elements are built in the open, and the Polymer authors eagerly encourage any and all forms of community contribution. When contributing, please follow these guidelines:
+
+### Filing Issues
+
+**If you are filing an issue to request a feature**, please provide a clear description of the feature. It can be helpful to describe answers to the following questions:
+
+ 1. **Who will use the feature?** _“As someone filling out a form…”_
+ 2. **When will they use the feature?** _“When I enter an invalid value…”_
+ 3. **What is the user’s goal?** _“I want to be visually notified that the value needs to be corrected…”_
+
+**If you are filing an issue to report a bug**, please provide:
+
+ 1. **A clear description of the bug and related expectations.** Consider using the following example template for reporting a bug:
+
+ ```markdown
+ The `paper-foo` element causes the page to turn pink when clicked.
+
+ ## Expected outcome
+
+ The page stays the same color.
+
+ ## Actual outcome
+
+ The page turns pink.
+
+ ## Steps to reproduce
+
+ 1. Put a `paper-foo` element in the page.
+ 2. Open the page in a web browser.
+ 3. Click the `paper-foo` element.
+ ```
+
+ 2. **A reduced test case that demonstrates the problem.** If possible, please include the test case as a JSBin. Start with this template to easily import and use relevant Polymer Elements: [https://jsbin.com/cagaye/edit?html,output](https://jsbin.com/cagaye/edit?html,output).
+
+ 3. **A list of browsers where the problem occurs.** This can be skipped if the problem is the same across all browsers.
+
+### Submitting Pull Requests
+
+**Before creating a pull request**, please ensure that an issue exists for the corresponding change in the pull request that you intend to make. **If an issue does not exist, please create one per the guidelines above**. The goal is to discuss the design and necessity of the proposed change with Polymer authors and community before diving into a pull request.
+
+When submitting pull requests, please provide:
+
+ 1. **A reference to the corresponding issue** or issues that will be closed by the pull request. Please refer to these issues in the pull request description using the following syntax:
+
+ ```markdown
+ (For a single issue)
+ Fixes #20
+
+ (For multiple issues)
+ Fixes #32, fixes #40
+ ```
+
+ 2. **A succinct description of the design** used to fix any related issues. For example:
+
+ ```markdown
+ This fixes #20 by removing styles that leaked which would cause the page to turn pink whenever `paper-foo` is clicked.
+ ```
+
+ 3. **At least one test for each bug fixed or feature added** as part of the pull request. Pull requests that fix bugs or add features without accompanying tests will not be considered.
+
+If a proposed change contains multiple commits, please [squash commits](https://www.google.com/url?q=http://blog.steveklabnik.com/posts/2012-11-08-how-to-squash-commits-in-a-github-pull-request) to as few as is necessary to succinctly express the change. A Polymer author can help you squash commits, so don’t be afraid to ask us if you need help with that!

+
+
+##&lt;paper-listbox&gt;
+
+Material design: [Menus](https://www.google.com/design/spec/components/menus.html)
+
+`<paper-listbox>` implements an accessible listbox control with Material Design styling. The focused item
+is highlighted, and the selected item has bolded text.
+
+```html
+<paper-listbox>
+  <paper-item>Item 1</paper-item>
+  <paper-item>Item 2</paper-item>
+</paper-listbox>
+```
+
+An initial selection can be specified with the `selected` attribute.
+
+```html
+<paper-listbox selected="0">
+  <paper-item>Item 1</paper-item>
+  <paper-item>Item 2</paper-item>
+</paper-listbox>
+```
+
+Make a multi-select listbox with the `multi` attribute. Items in a multi-select listbox can be deselected,
+and multiple item can be selected.
+
+```html
+<paper-listbox multi>
+  <paper-item>Item 1</paper-item>
+  <paper-item>Item 2</paper-item>
+</paper-listbox>
+```
+
+### Styling
+
+The following custom properties and mixins are available for styling:
+
+| Custom property | Description | Default |
+| --- | --- | --- |
+| `--paper-listbox-background-color` | Menu background color | `--primary-background-color` |
+| `--paper-listbox-color` | Menu foreground color | `--primary-text-color` |
+| `--paper-listbox` | Mixin applied to the listbox | `{}` |
+
+### Accessibility
+
+`<paper-listbox>` has `role="listbox"` by default. A multi-select listbox will also have
+`aria-multiselectable` set. It implements key bindings to navigate through the listbox with the up and
+down arrow keys, esc to exit the listbox, and enter to activate a listbox item. Typing the first letter
+of a listbox item will also focus it.

+Material design: [Menus](https://www.google.com/design/spec/components/menus.html)
+
+`<paper-listbox>` implements an accessible listbox control with Material Design styling. The focused item
+is highlighted, and the selected item has bolded text.
+
+    <paper-listbox>
+      <paper-item>Item 1</paper-item>
+      <paper-item>Item 2</paper-item>
+    </paper-listbox>
+
+An initial selection can be specified with the `selected` attribute.
+
+    <paper-listbox selected="0">
+      <paper-item>Item 1</paper-item>
+      <paper-item>Item 2</paper-item>
+    </paper-listbox>
+
+Make a multi-select listbox with the `multi` attribute. Items in a multi-select listbox can be deselected,
+and multiple item can be selected.
+
+    <paper-listbox multi>
+      <paper-item>Item 1</paper-item>
+      <paper-item>Item 2</paper-item>
+    </paper-listbox>
+
+### Styling
+
+The following custom properties and mixins are available for styling:
+
+Custom property | Description | Default
+----------------|-------------|----------
+`--paper-listbox-background-color`   | Menu background color                                            | `--primary-background-color`
+`--paper-listbox-color`              | Menu foreground color                                            | `--primary-text-color`
+`--paper-listbox`                    | Mixin applied to the listbox                                        | `{}`
+
+### Accessibility
+
+`<paper-listbox>` has `role="listbox"` by default. A multi-select listbox will also have
+`aria-multiselectable` set. It implements key bindings to navigate through the listbox with the up and
+down arrow keys, esc to exit the listbox, and enter to activate a listbox item. Typing the first letter
+of a listbox item will also focus it.

+# Polymer Elements
+## Guide for Contributors
+
+Polymer Elements are built in the open, and the Polymer authors eagerly encourage any and all forms of community contribution. When contributing, please follow these guidelines:
+
+### Filing Issues
+
+**If you are filing an issue to request a feature**, please provide a clear description of the feature. It can be helpful to describe answers to the following questions:
+
+ 1. **Who will use the feature?** _“As someone filling out a form…”_
+ 2. **When will they use the feature?** _“When I enter an invalid value…”_
+ 3. **What is the user’s goal?** _“I want to be visually notified that the value needs to be corrected…”_
+
+**If you are filing an issue to report a bug**, please provide:
+
+ 1. **A clear description of the bug and related expectations.** Consider using the following example template for reporting a bug:
+
+ ```markdown
+ The `paper-foo` element causes the page to turn pink when clicked.
+
+ ## Expected outcome
+
+ The page stays the same color.
+
+ ## Actual outcome
+
+ The page turns pink.
+
+ ## Steps to reproduce
+
+ 1. Put a `paper-foo` element in the page.
+ 2. Open the page in a web browser.
+ 3. Click the `paper-foo` element.
+ ```
+
+ 2. **A reduced test case that demonstrates the problem.** If possible, please include the test case as a JSBin. Start with this template to easily import and use relevant Polymer Elements: [https://jsbin.com/cagaye/edit?html,output](https://jsbin.com/cagaye/edit?html,output).
+
+ 3. **A list of browsers where the problem occurs.** This can be skipped if the problem is the same across all browsers.
+
+### Submitting Pull Requests
+
+**Before creating a pull request**, please ensure that an issue exists for the corresponding change in the pull request that you intend to make. **If an issue does not exist, please create one per the guidelines above**. The goal is to discuss the design and necessity of the proposed change with Polymer authors and community before diving into a pull request.
+
+When submitting pull requests, please provide:
+
+ 1. **A reference to the corresponding issue** or issues that will be closed by the pull request. Please refer to these issues in the pull request description using the following syntax:
+
+ ```markdown
+ (For a single issue)
+ Fixes #20
+
+ (For multiple issues)
+ Fixes #32, fixes #40
+ ```
+
+ 2. **A succinct description of the design** used to fix any related issues. For example:
+
+ ```markdown
+ This fixes #20 by removing styles that leaked which would cause the page to turn pink whenever `paper-foo` is clicked.
+ ```
+
+ 3. **At least one test for each bug fixed or feature added** as part of the pull request. Pull requests that fix bugs or add features without accompanying tests will not be considered.
+
+If a proposed change contains multiple commits, please [squash commits](https://www.google.com/url?q=http://blog.steveklabnik.com/posts/2012-11-08-how-to-squash-commits-in-a-github-pull-request) to as few as is necessary to succinctly express the change. A Polymer author can help you squash commits, so don’t be afraid to ask us if you need help with that!

+Material design: [Cards](https://www.google.com/design/spec/components/cards.html)
+
+`paper-material` is a container that renders two shadows on top of each other to
+create the effect of a lifted piece of paper.
+
+Example:
+
+```html
+<paper-material elevation="1">
+  ... content ...
+</paper-material>
+```

+# Polymer Elements
+## Guide for Contributors
+
+Polymer Elements are built in the open, and the Polymer authors eagerly encourage any and all forms of community contribution. When contributing, please follow these guidelines:
+
+### Filing Issues
+
+**If you are filing an issue to request a feature**, please provide a clear description of the feature. It can be helpful to describe answers to the following questions:
+
+ 1. **Who will use the feature?** _“As someone filling out a form…”_
+ 2. **When will they use the feature?** _“When I enter an invalid value…”_
+ 3. **What is the user’s goal?** _“I want to be visually notified that the value needs to be corrected…”_
+
+**If you are filing an issue to report a bug**, please provide:
+
+ 1. **A clear description of the bug and related expectations.** Consider using the following example template for reporting a bug:
+
+ ```markdown
+ The `paper-foo` element causes the page to turn pink when clicked.
+
+ ## Expected outcome
+
+ The page stays the same color.
+
+ ## Actual outcome
+
+ The page turns pink.
+
+ ## Steps to reproduce
+
+ 1. Put a `paper-foo` element in the page.
+ 2. Open the page in a web browser.
+ 3. Click the `paper-foo` element.
+ ```
+
+ 2. **A reduced test case that demonstrates the problem.** If possible, please include the test case as a JSBin. Start with this template to easily import and use relevant Polymer Elements: [https://jsbin.com/cagaye/edit?html,output](https://jsbin.com/cagaye/edit?html,output).
+
+ 3. **A list of browsers where the problem occurs.** This can be skipped if the problem is the same across all browsers.
+
+### Submitting Pull Requests
+
+**Before creating a pull request**, please ensure that an issue exists for the corresponding change in the pull request that you intend to make. **If an issue does not exist, please create one per the guidelines above**. The goal is to discuss the design and necessity of the proposed change with Polymer authors and community before diving into a pull request.
+
+When submitting pull requests, please provide:
+
+ 1. **A reference to the corresponding issue** or issues that will be closed by the pull request. Please refer to these issues in the pull request description using the following syntax:
+
+ ```markdown
+ (For a single issue)
+ Fixes #20
+
+ (For multiple issues)
+ Fixes #32, fixes #40
+ ```
+
+ 2. **A succinct description of the design** used to fix any related issues. For example:
+
+ ```markdown
+ This fixes #20 by removing styles that leaked which would cause the page to turn pink whenever `paper-foo` is clicked.
+ ```
+
+ 3. **At least one test for each bug fixed or feature added** as part of the pull request. Pull requests that fix bugs or add features without accompanying tests will not be considered.
+
+If a proposed change contains multiple commits, please [squash commits](https://www.google.com/url?q=http://blog.steveklabnik.com/posts/2012-11-08-how-to-squash-commits-in-a-github-pull-request) to as few as is necessary to succinctly express the change. A Polymer author can help you squash commits, so don’t be afraid to ask us if you need help with that!

+
+
+##&lt;paper-menu-button&gt;
+
+Material design: [Dropdown buttons](https://www.google.com/design/spec/components/buttons.html#buttons-dropdown-buttons)
+
+`paper-menu-button` allows one to compose a designated "trigger" element with
+another element that represents "content", to create a dropdown menu that
+displays the "content" when the "trigger" is clicked.
+
+The child element with the class `dropdown-trigger` will be used as the
+"trigger" element. The child element with the class `dropdown-content` will be
+used as the "content" element.
+
+The `paper-menu-button` is sensitive to its content's `iron-select` events. If
+the "content" element triggers an `iron-select` event, the `paper-menu-button`
+will close automatically.
+
+Example:
+
+```html
+<paper-menu-button>
+  <paper-icon-button icon="menu" class="dropdown-trigger"></paper-icon-button>
+  <paper-menu class="dropdown-content">
+    <paper-item>Share</paper-item>
+    <paper-item>Settings</paper-item>
+    <paper-item>Help</paper-item>
+  </paper-menu>
+</paper-menu-button>
+```
+
+### Styling
+
+The following custom properties and mixins are also available for styling:
+
+| Custom property | Description | Default |
+| --- | --- | --- |
+| `--paper-menu-button-dropdown-background` | Background color of the paper-menu-button dropdown | `--primary-background-color` |
+| `--paper-menu-button` | Mixin applied to the paper-menu-button | `{}` |
+| `--paper-menu-button-disabled` | Mixin applied to the paper-menu-button when disabled | `{}` |
+| `--paper-menu-button-dropdown` | Mixin applied to the paper-menu-button dropdown | `{}` |
+| `--paper-menu-button-content` | Mixin applied to the paper-menu-button content | `{}` |

+Material design: [Dropdown buttons](https://www.google.com/design/spec/components/buttons.html#buttons-dropdown-buttons)
+
+`paper-menu-button` allows one to compose a designated "trigger" element with
+another element that represents "content", to create a dropdown menu that
+displays the "content" when the "trigger" is clicked.
+
+The child element with the class `dropdown-trigger` will be used as the
+"trigger" element. The child element with the class `dropdown-content` will be
+used as the "content" element.
+
+The `paper-menu-button` is sensitive to its content's `iron-select` events. If
+the "content" element triggers an `iron-select` event, the `paper-menu-button`
+will close automatically.
+
+Example:
+
+    <paper-menu-button>
+      <paper-icon-button icon="menu" class="dropdown-trigger"></paper-icon-button>
+      <paper-menu class="dropdown-content">
+        <paper-item>Share</paper-item>
+        <paper-item>Settings</paper-item>
+        <paper-item>Help</paper-item>
+      </paper-menu>
+    </paper-menu-button>
+
+### Styling
+
+The following custom properties and mixins are also available for styling:
+
+Custom property | Description | Default
+----------------|-------------|----------
+`--paper-menu-button-dropdown-background` | Background color of the paper-menu-button dropdown | `--primary-background-color`
+`--paper-menu-button` | Mixin applied to the paper-menu-button | `{}`
+`--paper-menu-button-disabled` | Mixin applied to the paper-menu-button when disabled | `{}`
+`--paper-menu-button-dropdown` | Mixin applied to the paper-menu-button dropdown | `{}`
+`--paper-menu-button-content` | Mixin applied to the paper-menu-button content | `{}`

+# Polymer Elements
+## Guide for Contributors
+
+Polymer Elements are built in the open, and the Polymer authors eagerly encourage any and all forms of community contribution. When contributing, please follow these guidelines:
+
+### Filing Issues
+
+**If you are filing an issue to request a feature**, please provide a clear description of the feature. It can be helpful to describe answers to the following questions:
+
+ 1. **Who will use the feature?** _“As someone filling out a form…”_
+ 2. **When will they use the feature?** _“When I enter an invalid value…”_
+ 3. **What is the user’s goal?** _“I want to be visually notified that the value needs to be corrected…”_
+
+**If you are filing an issue to report a bug**, please provide:
+
+ 1. **A clear description of the bug and related expectations.** Consider using the following example template for reporting a bug:
+
+ ```markdown
+ The `paper-foo` element causes the page to turn pink when clicked.
+
+ ## Expected outcome
+
+ The page stays the same color.
+
+ ## Actual outcome
+
+ The page turns pink.
+
+ ## Steps to reproduce
+
+ 1. Put a `paper-foo` element in the page.
+ 2. Open the page in a web browser.
+ 3. Click the `paper-foo` element.
+ ```
+
+ 2. **A reduced test case that demonstrates the problem.** If possible, please include the test case as a JSBin. Start with this template to easily import and use relevant Polymer Elements: [https://jsbin.com/cagaye/edit?html,output](https://jsbin.com/cagaye/edit?html,output).
+
+ 3. **A list of browsers where the problem occurs.** This can be skipped if the problem is the same across all browsers.
+
+### Submitting Pull Requests
+
+**Before creating a pull request**, please ensure that an issue exists for the corresponding change in the pull request that you intend to make. **If an issue does not exist, please create one per the guidelines above**. The goal is to discuss the design and necessity of the proposed change with Polymer authors and community before diving into a pull request.
+
+When submitting pull requests, please provide:
+
+ 1. **A reference to the corresponding issue** or issues that will be closed by the pull request. Please refer to these issues in the pull request description using the following syntax:
+
+ ```markdown
+ (For a single issue)
+ Fixes #20
+
+ (For multiple issues)
+ Fixes #32, fixes #40
+ ```
+
+ 2. **A succinct description of the design** used to fix any related issues. For example:
+
+ ```markdown
+ This fixes #20 by removing styles that leaked which would cause the page to turn pink whenever `paper-foo` is clicked.
+ ```
+
+ 3. **At least one test for each bug fixed or feature added** as part of the pull request. Pull requests that fix bugs or add features without accompanying tests will not be considered.
+
+If a proposed change contains multiple commits, please [squash commits](https://www.google.com/url?q=http://blog.steveklabnik.com/posts/2012-11-08-how-to-squash-commits-in-a-github-pull-request) to as few as is necessary to succinctly express the change. A Polymer author can help you squash commits, so don’t be afraid to ask us if you need help with that!

+[![Build status](https://travis-ci.org/PolymerElements/paper-menu.svg?branch=master)](https://travis-ci.org/PolymerElements/paper-menu)
+
+_[Demo and API docs](https://elements.polymer-project.org/elements/paper-menu)_
+
+
+##&lt;paper-menu&gt;
+
+Material design: [Menus](https://www.google.com/design/spec/components/menus.html)
+
+`<paper-menu>` implements an accessible menu control with Material Design styling. The focused item
+is highlighted, and the selected item has bolded text.
+
+```html
+<paper-menu>
+  <paper-item>Item 1</paper-item>
+  <paper-item>Item 2</paper-item>
+</paper-menu>
+```
+
+An initial selection can be specified with the `selected` attribute.
+
+```html
+<paper-menu selected="0">
+  <paper-item>Item 1</paper-item>
+  <paper-item>Item 2</paper-item>
+</paper-menu>
+```
+
+Make a multi-select menu with the `multi` attribute. Items in a multi-select menu can be deselected,
+and multiple items can be selected.
+
+```html
+<paper-menu multi>
+  <paper-item>Item 1</paper-item>
+  <paper-item>Item 2</paper-item>
+</paper-menu>
+```
+
+### Styling
+
+The following custom properties and mixins are available for styling:
+
+| Custom property | Description | Default |
+| --- | --- | --- |
+| `--paper-menu-background-color` | Menu background color | `--primary-background-color` |
+| `--paper-menu-color` | Menu foreground color | `--primary-text-color` |
+| `--paper-menu-disabled-color` | Foreground color for a disabled item | `--disabled-text-color` |
+| `--paper-menu` | Mixin applied to the menu | `{}` |
+| `--paper-menu-selected-item` | Mixin applied to the selected item | `{}` |
+| `--paper-menu-focused-item` | Mixin applied to the focused item | `{}` |
+| `--paper-menu-focused-item-after` | Mixin applied to the ::after pseudo-element for the focused item | `{}` |
+
+### Accessibility
+
+`<paper-menu>` has `role="menu"` by default. A multi-select menu will also have
+`aria-multiselectable` set. It implements key bindings to navigate through the menu with the up and
+down arrow keys, esc to exit the menu, and enter to activate a menu item. Typing the first letter
+of a menu item will also focus it.
+
+
+
+##&lt;paper-submenu&gt;
+
+`<paper-submenu>` is a nested menu inside of a parent `<paper-menu>`. It
+consists of a trigger that expands or collapses another `<paper-menu>`:
+
+```html
+<paper-menu>
+  <paper-submenu>
+    <paper-item class="menu-trigger">Topics</paper-item>
+    <paper-menu class="menu-content">
+      <paper-item>Topic 1</paper-item>
+      <paper-item>Topic 2</paper-item>
+      <paper-item>Topic 3</paper-item>
+    </paper-menu>
+  </paper-submenu>
+  <paper-submenu>
+    <paper-item class="menu-trigger">Faves</paper-item>
+    <paper-menu class="menu-content">
+      <paper-item>Fave 1</paper-item>
+      <paper-item>Fave 2</paper-item>
+    </paper-menu>
+  </paper-submenu>
+  <paper-submenu disabled>
+    <paper-item class="menu-trigger">Unavailable</paper-item>
+    <paper-menu class="menu-content">
+      <paper-item>Disabled 1</paper-item>
+      <paper-item>Disabled 2</paper-item>
+    </paper-menu>
+  </paper-submenu>
+</paper-menu>
+```
+
+Just like in `<paper-menu>`, the focused item is highlighted, and the selected
+item has bolded text. Please see the `<paper-menu>` docs for which attributes
+(such as `multi` and `selected`), and styling options are available for the
+`menu-content` menu.

+Material design: [Menus](https://www.google.com/design/spec/components/menus.html)
+
+`<paper-menu>` implements an accessible menu control with Material Design styling. The focused item
+is highlighted, and the selected item has bolded text.
+
+    <paper-menu>
+      <paper-item>Item 1</paper-item>
+      <paper-item>Item 2</paper-item>
+    </paper-menu>
+
+An initial selection can be specified with the `selected` attribute.
+
+    <paper-menu selected="0">
+      <paper-item>Item 1</paper-item>
+      <paper-item>Item 2</paper-item>
+    </paper-menu>
+
+Make a multi-select menu with the `multi` attribute. Items in a multi-select menu can be deselected,
+and multiple items can be selected.
+
+    <paper-menu multi>
+      <paper-item>Item 1</paper-item>
+      <paper-item>Item 2</paper-item>
+    </paper-menu>
+
+### Styling
+
+The following custom properties and mixins are available for styling:
+
+Custom property | Description | Default
+----------------|-------------|----------
+`--paper-menu-background-color`   | Menu background color                                            | `--primary-background-color`
+`--paper-menu-color`              | Menu foreground color                                            | `--primary-text-color`
+`--paper-menu-disabled-color`     | Foreground color for a disabled item                             | `--disabled-text-color`
+`--paper-menu`                    | Mixin applied to the menu                                        | `{}`
+`--paper-menu-selected-item`      | Mixin applied to the selected item                               | `{}`
+`--paper-menu-focused-item`       | Mixin applied to the focused item                                | `{}`
+`--paper-menu-focused-item-after` | Mixin applied to the ::after pseudo-element for the focused item | `{}`
+
+### Accessibility
+
+`<paper-menu>` has `role="menu"` by default. A multi-select menu will also have
+`aria-multiselectable` set. It implements key bindings to navigate through the menu with the up and
+down arrow keys, esc to exit the menu, and enter to activate a menu item. Typing the first letter
+of a menu item will also focus it.

+        </paper-menu>
+      </paper-submenu>
+    </paper-menu>
+
+Just like in `<paper-menu>`, the focused item is highlighted, and the selected

+# Polymer Elements
+## Guide for Contributors
+
+Polymer Elements are built in the open, and the Polymer authors eagerly encourage any and all forms of community contribution. When contributing, please follow these guidelines:
+
+### Filing Issues
+
+**If you are filing an issue to request a feature**, please provide a clear description of the feature. It can be helpful to describe answers to the following questions:
+
+ 1. **Who will use the feature?** _“As someone filling out a form…”_
+ 2. **When will they use the feature?** _“When I enter an invalid value…”_
+ 3. **What is the user’s goal?** _“I want to be visually notified that the value needs to be corrected…”_
+
+**If you are filing an issue to report a bug**, please provide:
+
+ 1. **A clear description of the bug and related expectations.** Consider using the following example template for reporting a bug:
+
+ ```markdown
+ The `paper-foo` element causes the page to turn pink when clicked.
+
+ ## Expected outcome
+
+ The page stays the same color.
+
+ ## Actual outcome
+
+ The page turns pink.
+
+ ## Steps to reproduce
+
+ 1. Put a `paper-foo` element in the page.
+ 2. Open the page in a web browser.
+ 3. Click the `paper-foo` element.
+ ```
+
+ 2. **A reduced test case that demonstrates the problem.** If possible, please include the test case as a JSBin. Start with this template to easily import and use relevant Polymer Elements: [https://jsbin.com/cagaye/edit?html,output](https://jsbin.com/cagaye/edit?html,output).
+
+ 3. **A list of browsers where the problem occurs.** This can be skipped if the problem is the same across all browsers.
+
+### Submitting Pull Requests
+
+**Before creating a pull request**, please ensure that an issue exists for the corresponding change in the pull request that you intend to make. **If an issue does not exist, please create one per the guidelines above**. The goal is to discuss the design and necessity of the proposed change with Polymer authors and community before diving into a pull request.
+
+When submitting pull requests, please provide:
+
+ 1. **A reference to the corresponding issue** or issues that will be closed by the pull request. Please refer to these issues in the pull request description using the following syntax:
+
+ ```markdown
+ (For a single issue)
+ Fixes #20
+
+ (For multiple issues)
+ Fixes #32, fixes #40
+ ```
+
+ 2. **A succinct description of the design** used to fix any related issues. For example:
+
+ ```markdown
+ This fixes #20 by removing styles that leaked which would cause the page to turn pink whenever `paper-foo` is clicked.
+ ```
+
+ 3. **At least one test for each bug fixed or feature added** as part of the pull request. Pull requests that fix bugs or add features without accompanying tests will not be considered.
+
+If a proposed change contains multiple commits, please [squash commits](https://www.google.com/url?q=http://blog.steveklabnik.com/posts/2012-11-08-how-to-squash-commits-in-a-github-pull-request) to as few as is necessary to succinctly express the change. A Polymer author can help you squash commits, so don’t be afraid to ask us if you need help with that!

+The progress bars are for situations where the percentage completed can be
+determined. They give users a quick sense of how much longer an operation
+will take.
+
+Example:
+
+    <paper-progress value="10"></paper-progress>
+
+There is also a secondary progress which is useful for displaying intermediate
+progress, such as the buffer level during a streaming playback progress bar.
+
+Example:
+
+    <paper-progress value="10" secondary-progress="30"></paper-progress>
+
+### Styling progress bar:
+
+To change the active progress bar color:
+
+    paper-progress {
+       --paper-progress-active-color: #e91e63;
+    }
+
+To change the secondary progress bar color:
+
+    paper-progress {
+      --paper-progress-secondary-color: #f8bbd0;
+    }
+
+To change the progress bar background color:
+
+    paper-progress {
+      --paper-progress-container-color: #64ffda;
+    }
+
+Add the class `transiting` to a paper-progress to animate the progress bar when
+the value changed. You can also customize the transition:
+
+    paper-progress {
+      --paper-progress-transition-duration: 0.08s;
+      --paper-progress-transition-timing-function: ease;
+      --paper-progress-transition-transition-delay: 0s;
+    }
+
+To change the duration of the indeterminate cycle:

+# Polymer Elements
+## Guide for Contributors
+
+Polymer Elements are built in the open, and the Polymer authors eagerly encourage any and all forms of community contribution. When contributing, please follow these guidelines:
+
+### Filing Issues
+
+**If you are filing an issue to request a feature**, please provide a clear description of the feature. It can be helpful to describe answers to the following questions:
+
+ 1. **Who will use the feature?** _“As someone filling out a form…”_
+ 2. **When will they use the feature?** _“When I enter an invalid value…”_
+ 3. **What is the user’s goal?** _“I want to be visually notified that the value needs to be corrected…”_
+
+**If you are filing an issue to report a bug**, please provide:
+
+ 1. **A clear description of the bug and related expectations.** Consider using the following example template for reporting a bug:
+
+ ```markdown
+ The `paper-foo` element causes the page to turn pink when clicked.
+
+ ## Expected outcome
+
+ The page stays the same color.
+
+ ## Actual outcome
+
+ The page turns pink.
+
+ ## Steps to reproduce
+
+ 1. Put a `paper-foo` element in the page.
+ 2. Open the page in a web browser.
+ 3. Click the `paper-foo` element.
+ ```
+
+ 2. **A reduced test case that demonstrates the problem.** If possible, please include the test case as a JSBin. Start with this template to easily import and use relevant Polymer Elements: [https://jsbin.com/cagaye/edit?html,output](https://jsbin.com/cagaye/edit?html,output).
+
+ 3. **A list of browsers where the problem occurs.** This can be skipped if the problem is the same across all browsers.
+
+### Submitting Pull Requests
+
+**Before creating a pull request**, please ensure that an issue exists for the corresponding change in the pull request that you intend to make. **If an issue does not exist, please create one per the guidelines above**. The goal is to discuss the design and necessity of the proposed change with Polymer authors and community before diving into a pull request.
+
+When submitting pull requests, please provide:
+
+ 1. **A reference to the corresponding issue** or issues that will be closed by the pull request. Please refer to these issues in the pull request description using the following syntax:
+
+ ```markdown
+ (For a single issue)
+ Fixes #20
+
+ (For multiple issues)
+ Fixes #32, fixes #40
+ ```
+
+ 2. **A succinct description of the design** used to fix any related issues. For example:
+
+ ```markdown
+ This fixes #20 by removing styles that leaked which would cause the page to turn pink whenever `paper-foo` is clicked.
+ ```
+
+ 3. **At least one test for each bug fixed or feature added** as part of the pull request. Pull requests that fix bugs or add features without accompanying tests will not be considered.
+
+If a proposed change contains multiple commits, please [squash commits](https://www.google.com/url?q=http://blog.steveklabnik.com/posts/2012-11-08-how-to-squash-commits-in-a-github-pull-request) to as few as is necessary to succinctly express the change. A Polymer author can help you squash commits, so don’t be afraid to ask us if you need help with that!

+
+Material design: [Radio button](https://www.google.com/design/spec/components/selection-controls.html#selection-controls-radio-button)
+
+`paper-radio-button` is a button that can be either checked or unchecked.
+User can tap the radio button to check or uncheck it.
+
+Use a `<paper-radio-group>` to group a set of radio buttons.  When radio buttons
+are inside a radio group, exactly one radio button in the group can be checked
+at any time.
+
+Example:
+
+```html
+<paper-radio-button></paper-radio-button>
+<paper-radio-button>Item label</paper-radio-button>
+```
+
+### Styling
+
+The following custom properties and mixins are available for styling:
+
+| Custom property | Description | Default |
+| --- | --- | --- |
+| `--paper-radio-button-unchecked-background-color` | Radio button background color when the input is not checked | `transparent` |
+| `--paper-radio-button-unchecked-color` | Radio button color when the input is not checked | `--primary-text-color` |
+| `--paper-radio-button-unchecked-ink-color` | Selected/focus ripple color when the input is not checked | `--primary-text-color` |
+| `--paper-radio-button-checked-color` | Radio button color when the input is checked | `--primary-color` |
+| `--paper-radio-button-checked-ink-color` | Selected/focus ripple color when the input is checked | `--primary-color` |
+| `--paper-radio-button-size` | Size of the radio button | `16px` |
+| `--paper-radio-button-label-color` | Label color | `--primary-text-color` |
+| `--paper-radio-button-label-spacing` | Spacing between the label and the button | `10px` |
+
+This element applies the mixin `--paper-font-common-base` but does not import `paper-styles/typography.html`.
+In order to apply the `Roboto` font to this element, make sure you've imported `paper-styles/typography.html`.

+# Polymer Elements
+## Guide for Contributors
+
+Polymer Elements are built in the open, and the Polymer authors eagerly encourage any and all forms of community contribution. When contributing, please follow these guidelines:
+
+### Filing Issues
+
+**If you are filing an issue to request a feature**, please provide a clear description of the feature. It can be helpful to describe answers to the following questions:
+
+ 1. **Who will use the feature?** _“As someone filling out a form…”_
+ 2. **When will they use the feature?** _“When I enter an invalid value…”_
+ 3. **What is the user’s goal?** _“I want to be visually notified that the value needs to be corrected…”_
+
+**If you are filing an issue to report a bug**, please provide:
+
+ 1. **A clear description of the bug and related expectations.** Consider using the following example template for reporting a bug:
+
+ ```markdown
+ The `paper-foo` element causes the page to turn pink when clicked.
+
+ ## Expected outcome
+
+ The page stays the same color.
+
+ ## Actual outcome
+
+ The page turns pink.
+
+ ## Steps to reproduce
+
+ 1. Put a `paper-foo` element in the page.
+ 2. Open the page in a web browser.
+ 3. Click the `paper-foo` element.
+ ```
+
+ 2. **A reduced test case that demonstrates the problem.** If possible, please include the test case as a JSBin. Start with this template to easily import and use relevant Polymer Elements: [https://jsbin.com/cagaye/edit?html,output](https://jsbin.com/cagaye/edit?html,output).
+
+ 3. **A list of browsers where the problem occurs.** This can be skipped if the problem is the same across all browsers.
+
+### Submitting Pull Requests
+
+**Before creating a pull request**, please ensure that an issue exists for the corresponding change in the pull request that you intend to make. **If an issue does not exist, please create one per the guidelines above**. The goal is to discuss the design and necessity of the proposed change with Polymer authors and community before diving into a pull request.
+
+When submitting pull requests, please provide:
+
+ 1. **A reference to the corresponding issue** or issues that will be closed by the pull request. Please refer to these issues in the pull request description using the following syntax:
+
+ ```markdown
+ (For a single issue)
+ Fixes #20
+
+ (For multiple issues)
+ Fixes #32, fixes #40
+ ```
+
+ 2. **A succinct description of the design** used to fix any related issues. For example:
+
+ ```markdown
+ This fixes #20 by removing styles that leaked which would cause the page to turn pink whenever `paper-foo` is clicked.
+ ```
+
+ 3. **At least one test for each bug fixed or feature added** as part of the pull request. Pull requests that fix bugs or add features without accompanying tests will not be considered.
+
+If a proposed change contains multiple commits, please [squash commits](https://www.google.com/url?q=http://blog.steveklabnik.com/posts/2012-11-08-how-to-squash-commits-in-a-github-pull-request) to as few as is necessary to succinctly express the change. A Polymer author can help you squash commits, so don’t be afraid to ask us if you need help with that!

+##&lt;paper-radio-group&gt;
+
+Material design: [Radio button](https://www.google.com/design/spec/components/selection-controls.html#selection-controls-radio-button)
+
+`paper-radio-group` allows user to select at most one radio button from a set.
+Checking one radio button that belongs to a radio group unchecks any
+previously checked radio button within the same group. Use
+`selected` to get or set the selected radio button.
+
+The <paper-radio-buttons> inside the group must have the `name` attribute
+set.
+
+Example:
+
+```html
+<paper-radio-group selected="small">
+  <paper-radio-button name="small">Small</paper-radio-button>
+  <paper-radio-button name="medium">Medium</paper-radio-button>
+  <paper-radio-button name="large">Large</paper-radio-button>
+</paper-radio-group>
+```
+
+Radio-button-groups can be made optional, and allow zero buttons to be selected:
+
+```html
+<paper-radio-group selected="small" allow-empty-selection>
+  <paper-radio-button name="small">Small</paper-radio-button>
+  <paper-radio-button name="medium">Medium</paper-radio-button>
+  <paper-radio-button name="large">Large</paper-radio-button>
+</paper-radio-group>
+```
+
+See <a href="paper-radio-button">paper-radio-button</a> for more
+information about `paper-radio-button`.

+# Polymer Elements
+## Guide for Contributors
+
+Polymer Elements are built in the open, and the Polymer authors eagerly encourage any and all forms of community contribution. When contributing, please follow these guidelines:
+
+### Filing Issues
+
+**If you are filing an issue to request a feature**, please provide a clear description of the feature. It can be helpful to describe answers to the following questions:
+
+ 1. **Who will use the feature?** _“As someone filling out a form…”_
+ 2. **When will they use the feature?** _“When I enter an invalid value…”_
+ 3. **What is the user’s goal?** _“I want to be visually notified that the value needs to be corrected…”_
+
+**If you are filing an issue to report a bug**, please provide:
+
+ 1. **A clear description of the bug and related expectations.** Consider using the following example template for reporting a bug:
+
+ ```markdown
+ The `paper-foo` element causes the page to turn pink when clicked.
+
+ ## Expected outcome
+
+ The page stays the same color.
+
+ ## Actual outcome
+
+ The page turns pink.
+
+ ## Steps to reproduce
+
+ 1. Put a `paper-foo` element in the page.
+ 2. Open the page in a web browser.
+ 3. Click the `paper-foo` element.
+ ```
+
+ 2. **A reduced test case that demonstrates the problem.** If possible, please include the test case as a JSBin. Start with this template to easily import and use relevant Polymer Elements: [https://jsbin.com/cagaye/edit?html,output](https://jsbin.com/cagaye/edit?html,output).
+
+ 3. **A list of browsers where the problem occurs.** This can be skipped if the problem is the same across all browsers.
+
+### Submitting Pull Requests
+
+**Before creating a pull request**, please ensure that an issue exists for the corresponding change in the pull request that you intend to make. **If an issue does not exist, please create one per the guidelines above**. The goal is to discuss the design and necessity of the proposed change with Polymer authors and community before diving into a pull request.
+
+When submitting pull requests, please provide:
+
+ 1. **A reference to the corresponding issue** or issues that will be closed by the pull request. Please refer to these issues in the pull request description using the following syntax:
+
+ ```markdown
+ (For a single issue)
+ Fixes #20
+
+ (For multiple issues)
+ Fixes #32, fixes #40
+ ```
+
+ 2. **A succinct description of the design** used to fix any related issues. For example:
+
+ ```markdown
+ This fixes #20 by removing styles that leaked which would cause the page to turn pink whenever `paper-foo` is clicked.
+ ```
+
+ 3. **At least one test for each bug fixed or feature added** as part of the pull request. Pull requests that fix bugs or add features without accompanying tests will not be considered.
+
+If a proposed change contains multiple commits, please [squash commits](https://www.google.com/url?q=http://blog.steveklabnik.com/posts/2012-11-08-how-to-squash-commits-in-a-github-pull-request) to as few as is necessary to succinctly express the change. A Polymer author can help you squash commits, so don’t be afraid to ask us if you need help with that!

+Material design: [Surface reaction](https://www.google.com/design/spec/animation/responsive-interaction.html#responsive-interaction-surface-reaction)
+
+`paper-ripple` provides a visual effect that other paper elements can
+use to simulate a rippling effect emanating from the point of contact.  The
+effect can be visualized as a concentric circle with motion.

+Material design: [Surface reaction](https://www.google.com/design/spec/animation/responsive-interaction.html#responsive-interaction-surface-reaction)
+
+`paper-ripple` provides a visual effect that other paper elements can
+use to simulate a rippling effect emanating from the point of contact.  The
+effect can be visualized as a concentric circle with motion.
+
+Example:
+
+    <div style="position:relative">
+      <paper-ripple></paper-ripple>
+    </div>
+
+Note, it's important that the parent container of the ripple be relative position, otherwise
+the ripple will emanate outside of the desired container.
+
+`paper-ripple` listens to "mousedown" and "mouseup" events so it would display ripple
+effect when touches on it.  You can also defeat the default behavior and
+manually route the down and up actions to the ripple element.  Note that it is
+important if you call `downAction()` you will have to make sure to call
+`upAction()` so that `paper-ripple` would end the animation loop.
+
+Example:
+
+    <paper-ripple id="ripple" style="pointer-events: none;"></paper-ripple>
+    ...
+    downAction: function(e) {
+      this.$.ripple.downAction({detail: {x: e.x, y: e.y}});
+    },
+    upAction: function(e) {
+      this.$.ripple.upAction();
+    }
+
+Styling ripple effect:
+
+  Use CSS color property to style the ripple:
+
+    paper-ripple {
+      color: #4285f4;
+    }
+
+  Note that CSS color property is inherited so it is not required to set it on
+  the `paper-ripple` element directly.
+
+By default, the ripple is centered on the point of contact.  Apply the `recenters`
+attribute to have the ripple grow toward the center of its container.
+
+    <paper-ripple recenters></paper-ripple>
+
+You can also  center the ripple inside its container from the start.
+
+    <paper-ripple center></paper-ripple>
+
+Apply `circle` class to make the rippling effect within a circle.

+# Polymer Elements
+## Guide for Contributors
+
+Polymer Elements are built in the open, and the Polymer authors eagerly encourage any and all forms of community contribution. When contributing, please follow these guidelines:
+
+### Filing Issues
+
+**If you are filing an issue to request a feature**, please provide a clear description of the feature. It can be helpful to describe answers to the following questions:
+
+ 1. **Who will use the feature?** _“As someone filling out a form…”_
+ 2. **When will they use the feature?** _“When I enter an invalid value…”_
+ 3. **What is the user’s goal?** _“I want to be visually notified that the value needs to be corrected…”_
+
+**If you are filing an issue to report a bug**, please provide:
+
+ 1. **A clear description of the bug and related expectations.** Consider using the following example template for reporting a bug:
+
+ ```markdown
+ The `paper-foo` element causes the page to turn pink when clicked.
+
+ ## Expected outcome
+
+ The page stays the same color.
+
+ ## Actual outcome
+
+ The page turns pink.
+
+ ## Steps to reproduce
+
+ 1. Put a `paper-foo` element in the page.
+ 2. Open the page in a web browser.
+ 3. Click the `paper-foo` element.
+ ```
+
+ 2. **A reduced test case that demonstrates the problem.** If possible, please include the test case as a JSBin. Start with this template to easily import and use relevant Polymer Elements: [https://jsbin.com/cagaye/edit?html,output](https://jsbin.com/cagaye/edit?html,output).
+
+ 3. **A list of browsers where the problem occurs.** This can be skipped if the problem is the same across all browsers.
+
+### Submitting Pull Requests
+
+**Before creating a pull request**, please ensure that an issue exists for the corresponding change in the pull request that you intend to make. **If an issue does not exist, please create one per the guidelines above**. The goal is to discuss the design and necessity of the proposed change with Polymer authors and community before diving into a pull request.
+
+When submitting pull requests, please provide:
+
+ 1. **A reference to the corresponding issue** or issues that will be closed by the pull request. Please refer to these issues in the pull request description using the following syntax:
+
+ ```markdown
+ (For a single issue)
+ Fixes #20
+
+ (For multiple issues)
+ Fixes #32, fixes #40
+ ```
+
+ 2. **A succinct description of the design** used to fix any related issues. For example:
+
+ ```markdown
+ This fixes #20 by removing styles that leaked which would cause the page to turn pink whenever `paper-foo` is clicked.
+ ```
+
+ 3. **At least one test for each bug fixed or feature added** as part of the pull request. Pull requests that fix bugs or add features without accompanying tests will not be considered.
+
+If a proposed change contains multiple commits, please [squash commits](https://www.google.com/url?q=http://blog.steveklabnik.com/posts/2012-11-08-how-to-squash-commits-in-a-github-pull-request) to as few as is necessary to succinctly express the change. A Polymer author can help you squash commits, so don’t be afraid to ask us if you need help with that!

+# Polymer Elements
+## Guide for Contributors
+
+Polymer Elements are built in the open, and the Polymer authors eagerly encourage any and all forms of community contribution. When contributing, please follow these guidelines:
+
+### Filing Issues
+
+**If you are filing an issue to request a feature**, please provide a clear description of the feature. It can be helpful to describe answers to the following questions:
+
+ 1. **Who will use the feature?** _“As someone filling out a form…”_
+ 2. **When will they use the feature?** _“When I enter an invalid value…”_
+ 3. **What is the user’s goal?** _“I want to be visually notified that the value needs to be corrected…”_
+
+**If you are filing an issue to report a bug**, please provide:
+
+ 1. **A clear description of the bug and related expectations.** Consider using the following example template for reporting a bug:
+
+ ```markdown
+ The `paper-foo` element causes the page to turn pink when clicked.
+
+ ## Expected outcome
+
+ The page stays the same color.
+
+ ## Actual outcome
+
+ The page turns pink.
+
+ ## Steps to reproduce
+
+ 1. Put a `paper-foo` element in the page.
+ 2. Open the page in a web browser.
+ 3. Click the `paper-foo` element.
+ ```
+
+ 2. **A reduced test case that demonstrates the problem.** If possible, please include the test case as a JSBin. Start with this template to easily import and use relevant Polymer Elements: [https://jsbin.com/cagaye/edit?html,output](https://jsbin.com/cagaye/edit?html,output).
+
+ 3. **A list of browsers where the problem occurs.** This can be skipped if the problem is the same across all browsers.
+
+### Submitting Pull Requests
+
+**Before creating a pull request**, please ensure that an issue exists for the corresponding change in the pull request that you intend to make. **If an issue does not exist, please create one per the guidelines above**. The goal is to discuss the design and necessity of the proposed change with Polymer authors and community before diving into a pull request.
+
+When submitting pull requests, please provide:
+
+ 1. **A reference to the corresponding issue** or issues that will be closed by the pull request. Please refer to these issues in the pull request description using the following syntax:
+
+ ```markdown
+ (For a single issue)
+ Fixes #20
+
+ (For multiple issues)
+ Fixes #32, fixes #40
+ ```
+
+ 2. **A succinct description of the design** used to fix any related issues. For example:
+
+ ```markdown
+ This fixes #20 by removing styles that leaked which would cause the page to turn pink whenever `paper-foo` is clicked.
+ ```
+
+ 3. **At least one test for each bug fixed or feature added** as part of the pull request. Pull requests that fix bugs or add features without accompanying tests will not be considered.
+
+If a proposed change contains multiple commits, please [squash commits](https://www.google.com/url?q=http://blog.steveklabnik.com/posts/2012-11-08-how-to-squash-commits-in-a-github-pull-request) to as few as is necessary to succinctly express the change. A Polymer author can help you squash commits, so don’t be afraid to ask us if you need help with that!

+
+##&lt;paper-styles&gt;
+
+The `<paper-styles>` component provides simple ways to use Material Design CSS styles
+in your application. The following imports are available:
+
+1. [color.html](https://github.com/PolymerElements/paper-styles/blob/master/color.html):
+a complete list of the colors defined in the Material Design [palette](https://www.google.com/design/spec/style/color.html)
+
+
+1. [default-theme.html](https://github.com/PolymerElements/paper-styles/blob/master/default-theme.html): text,
+background and accent colors that match the default Material Design theme
+
+
+1. [shadow.html](https://github.com/PolymerElements/paper-styles/blob/master/shadow.html): Material Design
+[elevation](https://www.google.com/design/spec/what-is-material/elevation-shadows.html) and shadow styles
+
+
+1. [typography.html](https://github.com/PolymerElements/paper-styles/blob/master/typography.html):
+Material Design [font](http://www.google.com/design/spec/style/typography.html#typography-styles) styles and sizes
+
+
+1. [demo-pages.html](https://github.com/PolymerElements/paper-styles/blob/master/demo-pages.html): generic styles
+used in the PolymerElements demo pages
+
+
+
+We recommend importing each of these individual files, and using the style mixins
+available in each ones, rather than the aggregated `paper-styles.html` as a whole.

+a complete list of the colors defined in the Material Design [palette](https://www.google.com/design/spec/style/color.html)
+
+2. [default-theme.html](https://github.com/PolymerElements/paper-styles/blob/master/default-theme.html): text,
+background and accent colors that match the default Material Design theme
+
+3. [shadow.html](https://github.com/PolymerElements/paper-styles/blob/master/shadow.html): Material Design
+[elevation](https://www.google.com/design/spec/what-is-material/elevation-shadows.html) and shadow styles
+
+4. [typography.html](https://github.com/PolymerElements/paper-styles/blob/master/typography.html):
+Material Design [font](http://www.google.com/design/spec/style/typography.html#typography-styles) styles and sizes
+
+5. [demo-pages.html](https://github.com/PolymerElements/paper-styles/blob/master/demo-pages.html): generic styles
+used in the PolymerElements demo pages
+
+We recommend importing each of these individual files, and using the style mixins
+available in each ones, rather than the aggregated `paper-styles.html` as a whole.

+# Polymer Elements
+## Guide for Contributors
+
+Polymer Elements are built in the open, and the Polymer authors eagerly encourage any and all forms of community contribution. When contributing, please follow these guidelines:
+
+### Filing Issues
+
+**If you are filing an issue to request a feature**, please provide a clear description of the feature. It can be helpful to describe answers to the following questions:
+
+ 1. **Who will use the feature?** _“As someone filling out a form…”_
+ 2. **When will they use the feature?** _“When I enter an invalid value…”_
+ 3. **What is the user’s goal?** _“I want to be visually notified that the value needs to be corrected…”_
+
+**If you are filing an issue to report a bug**, please provide:
+
+ 1. **A clear description of the bug and related expectations.** Consider using the following example template for reporting a bug:
+
+ ```markdown
+ The `paper-foo` element causes the page to turn pink when clicked.
+
+ ## Expected outcome
+
+ The page stays the same color.
+
+ ## Actual outcome
+
+ The page turns pink.
+
+ ## Steps to reproduce
+
+ 1. Put a `paper-foo` element in the page.
+ 2. Open the page in a web browser.
+ 3. Click the `paper-foo` element.
+ ```
+
+ 2. **A reduced test case that demonstrates the problem.** If possible, please include the test case as a JSBin. Start with this template to easily import and use relevant Polymer Elements: [https://jsbin.com/cagaye/edit?html,output](https://jsbin.com/cagaye/edit?html,output).
+
+ 3. **A list of browsers where the problem occurs.** This can be skipped if the problem is the same across all browsers.
+
+### Submitting Pull Requests
+
+**Before creating a pull request**, please ensure that an issue exists for the corresponding change in the pull request that you intend to make. **If an issue does not exist, please create one per the guidelines above**. The goal is to discuss the design and necessity of the proposed change with Polymer authors and community before diving into a pull request.
+
+When submitting pull requests, please provide:
+
+ 1. **A reference to the corresponding issue** or issues that will be closed by the pull request. Please refer to these issues in the pull request description using the following syntax:
+
+ ```markdown
+ (For a single issue)
+ Fixes #20
+
+ (For multiple issues)
+ Fixes #32, fixes #40
+ ```
+
+ 2. **A succinct description of the design** used to fix any related issues. For example:
+
+ ```markdown
+ This fixes #20 by removing styles that leaked which would cause the page to turn pink whenever `paper-foo` is clicked.
+ ```
+
+ 3. **At least one test for each bug fixed or feature added** as part of the pull request. Pull requests that fix bugs or add features without accompanying tests will not be considered.
+
+If a proposed change contains multiple commits, please [squash commits](https://www.google.com/url?q=http://blog.steveklabnik.com/posts/2012-11-08-how-to-squash-commits-in-a-github-pull-request) to as few as is necessary to succinctly express the change. A Polymer author can help you squash commits, so don’t be afraid to ask us if you need help with that!

+`paper-tab` is styled to look like a tab.  It should be used in conjunction with
+`paper-tabs`.
+
+Example:
+
+    <paper-tabs selected="0">

+      <paper-tab>TAB 2</paper-tab>
+      <paper-tab>TAB 3</paper-tab>

+
+### Styling
+
+The following custom properties and mixins are available for styling:
+
+Custom property | Description | Default
+----------------|-------------|----------
+`--paper-tab-ink` | Ink color | `--paper-yellow-a100`
+`--paper-tab` | Mixin applied to the tab | `{}`
+`--paper-tab-content` | Mixin applied to the tab content | `{}`
+`--paper-tab-content-unselected` | Mixin applied to the tab content when the tab is not selected | `{}`
+
+This element applies the mixin `--paper-font-common-base` but does not import `paper-styles/typography.html`.
+In order to apply the `Roboto` font to this element, make sure you've imported `paper-styles/typography.html`.

+Material design: [Tabs](https://www.google.com/design/spec/components/tabs.html)
+
+`paper-tabs` makes it easy to explore and switch between different views or functional aspects of
+an app, or to browse categorized data sets.
+
+Use `selected` property to get or set the selected tab.
+
+Example:
+
+    <paper-tabs selected="0">
+      <paper-tab>TAB 1</paper-tab>
+      <paper-tab>TAB 2</paper-tab>
+      <paper-tab>TAB 3</paper-tab>
+    </paper-tabs>
+
+See <a href="?active=paper-tab">paper-tab</a> for more information about
+`paper-tab`.
+
+A common usage for `paper-tabs` is to use it along with `iron-pages` to switch
+between different views.
+
+    <paper-tabs selected="{{selected}}">
+      <paper-tab>Tab 1</paper-tab>
+      <paper-tab>Tab 2</paper-tab>
+      <paper-tab>Tab 3</paper-tab>
+    </paper-tabs>
+
+    <iron-pages selected="{{selected}}">
+      <div>Page 1</div>
+      <div>Page 2</div>
+      <div>Page 3</div>
+    </iron-pages>
+
+
+To use links in tabs, add `link` attribute to `paper-tab` and put an `<a>`
+element in `paper-tab` with a `tabindex` of -1.
+
+Example:
+
+<pre><code>
+&lt;style is="custom-style">
+  .link {
+    &#64;apply(--layout-horizontal);
+    &#64;apply(--layout-center-center);
+  }
+&lt;/style>
+
+&lt;paper-tabs selected="0">
+  &lt;paper-tab link>
+    &lt;a href="#link1" class="link" tabindex="-1">TAB ONE&lt;/a>
+  &lt;/paper-tab>
+  &lt;paper-tab link>
+    &lt;a href="#link2" class="link" tabindex="-1">TAB TWO&lt;/a>
+  &lt;/paper-tab>
+  &lt;paper-tab link>
+    &lt;a href="#link3" class="link" tabindex="-1">TAB THREE&lt;/a>
+  &lt;/paper-tab>
+&lt;/paper-tabs>
+</code></pre>
+
+### Styling
+
+The following custom properties and mixins are available for styling:
+
+Custom property | Description | Default
+----------------|-------------|----------
+`--paper-tabs-selection-bar-color` | Color for the selection bar | `--paper-yellow-a100`
+`--paper-tabs-selection-bar` | Mixin applied to the selection bar | `{}`
+`--paper-tabs` | Mixin applied to the tabs | `{}`
+`--paper-tabs-content` | Mixin applied to the content container of tabs | `{}`
+`--paper-tabs-container` | Mixin applied to the layout container of tabs | `{}`

+# Polymer Elements
+## Guide for Contributors
+
+Polymer Elements are built in the open, and the Polymer authors eagerly encourage any and all forms of community contribution. When contributing, please follow these guidelines:
+
+### Filing Issues
+
+**If you are filing an issue to request a feature**, please provide a clear description of the feature. It can be helpful to describe answers to the following questions:
+
+ 1. **Who will use the feature?** _“As someone filling out a form…”_
+ 2. **When will they use the feature?** _“When I enter an invalid value…”_
+ 3. **What is the user’s goal?** _“I want to be visually notified that the value needs to be corrected…”_
+
+**If you are filing an issue to report a bug**, please provide:
+
+ 1. **A clear description of the bug and related expectations.** Consider using the following example template for reporting a bug:
+
+ ```markdown
+ The `paper-foo` element causes the page to turn pink when clicked.
+
+ ## Expected outcome
+
+ The page stays the same color.
+
+ ## Actual outcome
+
+ The page turns pink.
+
+ ## Steps to reproduce
+
+ 1. Put a `paper-foo` element in the page.
+ 2. Open the page in a web browser.
+ 3. Click the `paper-foo` element.
+ ```
+
+ 2. **A reduced test case that demonstrates the problem.** If possible, please include the test case as a JSBin. Start with this template to easily import and use relevant Polymer Elements: [https://jsbin.com/cagaye/edit?html,output](https://jsbin.com/cagaye/edit?html,output).
+
+ 3. **A list of browsers where the problem occurs.** This can be skipped if the problem is the same across all browsers.
+
+### Submitting Pull Requests
+
+**Before creating a pull request**, please ensure that an issue exists for the corresponding change in the pull request that you intend to make. **If an issue does not exist, please create one per the guidelines above**. The goal is to discuss the design and necessity of the proposed change with Polymer authors and community before diving into a pull request.
+
+When submitting pull requests, please provide:
+
+ 1. **A reference to the corresponding issue** or issues that will be closed by the pull request. Please refer to these issues in the pull request description using the following syntax:
+
+ ```markdown
+ (For a single issue)
+ Fixes #20
+
+ (For multiple issues)
+ Fixes #32, fixes #40
+ ```
+
+ 2. **A succinct description of the design** used to fix any related issues. For example:
+
+ ```markdown
+ This fixes #20 by removing styles that leaked which would cause the page to turn pink whenever `paper-foo` is clicked.
+ ```
+
+ 3. **At least one test for each bug fixed or feature added** as part of the pull request. Pull requests that fix bugs or add features without accompanying tests will not be considered.
+
+If a proposed change contains multiple commits, please [squash commits](https://www.google.com/url?q=http://blog.steveklabnik.com/posts/2012-11-08-how-to-squash-commits-in-a-github-pull-request) to as few as is necessary to succinctly express the change. A Polymer author can help you squash commits, so don’t be afraid to ask us if you need help with that!

+##&lt;paper-toast&gt;
+
+Material design: [Snackbars & toasts](https://www.google.com/design/spec/components/snackbars-toasts.html)
+
+`paper-toast` provides a subtle notification toast. Only one `paper-toast` will
+be visible on screen.
+
+Use `opened` to show the toast:
+
+Example:
+
+```html
+<paper-toast text="Hello world!" opened></paper-toast>
+```
+
+Also `open()` or `show()` can be used to show the toast:
+
+Example:
+
+```html
+<paper-button on-click="openToast">Open Toast</paper-button>
+<paper-toast id="toast" text="Hello world!"></paper-toast>
+
+...
+
+openToast: function() {
+  this.$.toast.open();
+}
+```
+
+Set `duration` to 0, a negative number or Infinity to persist the toast on screen:
+
+Example:
+
+```html
+<paper-toast text="Terms and conditions" opened duration="0">
+  <a href="#">Show more</a>
+</paper-toast>
+```
+
+### Styling
+
+The following custom properties and mixins are available for styling:
+
+| Custom property | Description | Default |
+| --- | --- | --- |
+| `--paper-toast-background-color` | The paper-toast background-color | `#323232` |
+| `--paper-toast-color` | The paper-toast color | `#f1f1f1` |
+
+This element applies the mixin `--paper-font-common-base` but does not import `paper-styles/typography.html`.
+In order to apply the `Roboto` font to this element, make sure you've imported `paper-styles/typography.html`.

+# Polymer Elements
+## Guide for Contributors
+
+Polymer Elements are built in the open, and the Polymer authors eagerly encourage any and all forms of community contribution. When contributing, please follow these guidelines:
+
+### Filing Issues
+
+**If you are filing an issue to request a feature**, please provide a clear description of the feature. It can be helpful to describe answers to the following questions:
+
+ 1. **Who will use the feature?** _“As someone filling out a form…”_
+ 2. **When will they use the feature?** _“When I enter an invalid value…”_
+ 3. **What is the user’s goal?** _“I want to be visually notified that the value needs to be corrected…”_
+
+**If you are filing an issue to report a bug**, please provide:
+
+ 1. **A clear description of the bug and related expectations.** Consider using the following example template for reporting a bug:
+
+ ```markdown
+ The `paper-foo` element causes the page to turn pink when clicked.
+
+ ## Expected outcome
+
+ The page stays the same color.
+
+ ## Actual outcome
+
+ The page turns pink.
+
+ ## Steps to reproduce
+
+ 1. Put a `paper-foo` element in the page.
+ 2. Open the page in a web browser.
+ 3. Click the `paper-foo` element.
+ ```
+
+ 2. **A reduced test case that demonstrates the problem.** If possible, please include the test case as a JSBin. Start with this template to easily import and use relevant Polymer Elements: [https://jsbin.com/cagaye/edit?html,output](https://jsbin.com/cagaye/edit?html,output).
+
+ 3. **A list of browsers where the problem occurs.** This can be skipped if the problem is the same across all browsers.
+
+### Submitting Pull Requests
+
+**Before creating a pull request**, please ensure that an issue exists for the corresponding change in the pull request that you intend to make. **If an issue does not exist, please create one per the guidelines above**. The goal is to discuss the design and necessity of the proposed change with Polymer authors and community before diving into a pull request.
+
+When submitting pull requests, please provide:
+
+ 1. **A reference to the corresponding issue** or issues that will be closed by the pull request. Please refer to these issues in the pull request description using the following syntax:
+
+ ```markdown
+ (For a single issue)
+ Fixes #20
+
+ (For multiple issues)
+ Fixes #32, fixes #40
+ ```
+
+ 2. **A succinct description of the design** used to fix any related issues. For example:
+
+ ```markdown
+ This fixes #20 by removing styles that leaked which would cause the page to turn pink whenever `paper-foo` is clicked.
+ ```
+
+ 3. **At least one test for each bug fixed or feature added** as part of the pull request. Pull requests that fix bugs or add features without accompanying tests will not be considered.
+
+If a proposed change contains multiple commits, please [squash commits](https://www.google.com/url?q=http://blog.steveklabnik.com/posts/2012-11-08-how-to-squash-commits-in-a-github-pull-request) to as few as is necessary to succinctly express the change. A Polymer author can help you squash commits, so don’t be afraid to ask us if you need help with that!

+
+##&lt;paper-tooltip&gt;
+
+Material design: [Tooltips](https://www.google.com/design/spec/components/tooltips.html)
+
+`<paper-tooltip>` is a label that appears on hover and focus when the user
+hovers over an element with the cursor or with the keyboard. It will be centered
+to an anchor element specified in the `for` attribute, or, if that doesn't exist,
+centered to the parent node containing it.
+
+Example:
+
+```html
+<div style="display:inline-block">
+  <button>Click me!</button>
+  <paper-tooltip>Tooltip text</paper-tooltip>
+</div>
+
+<div>
+  <button id="btn">Click me!</button>
+  <paper-tooltip for="btn">Tooltip text</paper-tooltip>
+</div>
+```
+
+The tooltip can be positioned on the top|bottom|left|right of the anchor using
+the `position` attribute. The default position is bottom.
+
+```html
+<paper-tooltip for="btn" position="left">Tooltip text</paper-tooltip>
+<paper-tooltip for="btn" position="top">Tooltip text</paper-tooltip>
+```
+
+### Styling
+
+The following custom properties and mixins are available for styling:
+
+| Custom property | Description | Default |
+| --- | --- | --- |
+| `--paper-tooltip-background` | The background color of the tooltip | `#616161` |
+| `--paper-tooltip-opacity` | The opacity of the tooltip | `0.9` |
+| `--paper-tooltip-text-color` | The text color of the tooltip | `white` |
+| `--paper-tooltip` | Mixin applied to the tooltip | `{}` |

+      <button id="btn">Click me!</button>
+      <paper-tooltip for="btn">Tooltip text</paper-tooltip>
+    </div>
+
+The tooltip can be positioned on the top|bottom|left|right of the anchor using
+the `position` attribute. The default position is bottom.

+# Polymer Elements
+## Guide for Contributors
+
+Polymer Elements are built in the open, and the Polymer authors eagerly encourage any and all forms of community contribution. When contributing, please follow these guidelines:
+
+### Filing Issues
+
+**If you are filing an issue to request a feature**, please provide a clear description of the feature. It can be helpful to describe answers to the following questions:
+
+ 1. **Who will use the feature?** _“As someone filling out a form…”_
+ 2. **When will they use the feature?** _“When I enter an invalid value…”_
+ 3. **What is the user’s goal?** _“I want to be visually notified that the value needs to be corrected…”_
+
+**If you are filing an issue to report a bug**, please provide:
+
+ 1. **A clear description of the bug and related expectations.** Consider using the following example template for reporting a bug:
+
+ ```markdown
+ The `paper-foo` element causes the page to turn pink when clicked.
+
+ ## Expected outcome
+
+ The page stays the same color.
+
+ ## Actual outcome
+
+ The page turns pink.
+
+ ## Steps to reproduce
+
+ 1. Put a `paper-foo` element in the page.
+ 2. Open the page in a web browser.
+ 3. Click the `paper-foo` element.
+ ```
+
+ 2. **A reduced test case that demonstrates the problem.** If possible, please include the test case as a JSBin. Start with this template to easily import and use relevant Polymer Elements: [https://jsbin.com/cagaye/edit?html,output](https://jsbin.com/cagaye/edit?html,output).
+
+ 3. **A list of browsers where the problem occurs.** This can be skipped if the problem is the same across all browsers.
+
+### Submitting Pull Requests
+
+**Before creating a pull request**, please ensure that an issue exists for the corresponding change in the pull request that you intend to make. **If an issue does not exist, please create one per the guidelines above**. The goal is to discuss the design and necessity of the proposed change with Polymer authors and community before diving into a pull request.
+
+When submitting pull requests, please provide:
+
+ 1. **A reference to the corresponding issue** or issues that will be closed by the pull request. Please refer to these issues in the pull request description using the following syntax:
+
+ ```markdown
+ (For a single issue)
+ Fixes #20
+
+ (For multiple issues)
+ Fixes #32, fixes #40
+ ```
+
+ 2. **A succinct description of the design** used to fix any related issues. For example:
+
+ ```markdown
+ This fixes #20 by removing styles that leaked which would cause the page to turn pink whenever `paper-foo` is clicked.
+ ```
+
+ 3. **At least one test for each bug fixed or feature added** as part of the pull request. Pull requests that fix bugs or add features without accompanying tests will not be considered.
+
+If a proposed change contains multiple commits, please [squash commits](https://www.google.com/url?q=http://blog.steveklabnik.com/posts/2012-11-08-how-to-squash-commits-in-a-github-pull-request) to as few as is necessary to succinctly express the change. A Polymer author can help you squash commits, so don’t be afraid to ask us if you need help with that!

+# ShadyCSS
+
+ShadyCSS provides a library to simulate ShadowDOM style encapsulation (ScopingShim), a shim for the proposed CSS mixin `@apply` syntax (ApplyShim), and a library to integrate document-level stylesheets with both of the former libraries (CustomStyleInterface).
+
+## Requirements
+ShadyCSS requires support for the `<template>` element, ShadowDOM, MutationObserver, Promise, and Object.assign
+
+## Loading
+
+ShadyCSS can be used by loading the ScopingShim, ApplyShim, CustomStyleInterface, or any combination of those.
+
+The most-supported loading order is:
+1. ScopingShim
+1. ApplyShim
+1. CustomStyleInterface
+
+All libraries will expose an object on `window` named `ShadyCSS` with the following interface:
+
+```js
+ShadyCSS = {
+  prepareTemplate(templateElement, elementName, elementExtension){},
+  styleElement(element){},
+  styleSubtree(element, overrideProperties){},
+  styleDocument(overrideProperties){},
+  getComputedStyleValue(element, propertyName){
+    return // style value for property name on element
+  },
+  nativeCss: Boolean,
+  nativeShadow: Boolean
+}
+```
+
+## About ScopingShim
+
+ScopingShim provides simulated ShadyDOM style encapsulation, and a shim for CSS Custom Properties.
+
+ScopingShim works by rewriting style contents and transforming selectors to enforce scoping.
+Additionally, if CSS Custom Properties is not detected, ScopingShim will replace CSS Custom Property usage with realized values.
+
+### Example:
+Here's an example of a custom element when Scoping Shim is not needed.
+
+```html
+<my-element>
+  <!-- shadow-root -->
+  <style>
+  :host {
+    display: block;
+  }
+  #container slot::slotted(*) {
+    color: gray;
+  }
+  #foo {
+    color: black;
+  }
+  </style>
+  <div id="foo">Shadow</div>
+  <div id="container">
+    <slot>
+      <!-- span distributed here -->
+    </slot>
+  </div>
+  <!-- /shadow-root -->
+  <span>Light</span>
+</my-element>
+```
+
+becomes:
+
+```html
+<style scope="my-element">
+my-element {
+  display: block;
+}
+#container.my-element > * {
+  color: gray;
+}
+#foo.my-element {
+  color: black;
+}
+</style>
+<my-element>
+<div id="foo">Shadow</div>
+<div id="container">
+  <span>Light</span>
+</div>
+</my-element>
+```
+
+## About ApplyShim
+
+ApplyShim provides a shim for the `@apply` syntax proposed at https://tabatkins.github.io/specs/css-apply-rule/, which expands the definition CSS Custom Properties to include objects that can be applied as a block.
+
+This is done by transforming the block definition into a set of CSS Custom Properties, and replacing uses of `@apply` with consumption of those custom properties.
+
+### Status:
+
+The `@apply` proposal has been abandoned in favor of the ::part/::theme [Shadow Parts spec](https://tabatkins.github.io/specs/css-shadow-parts/). Therefore, the ApplyShim library is deprecated and provided only for backwards compatibility. Support going forward will be limited to critical bug fixes.
+
+### Known Issues:
+
+* Mixin properties cannot be modified at runtime.
+* Nested mixins are not supported.
+* Shorthand properties are not expanded and may conflict with more explicit properties. Whenever shorthand notations are used in conjunction with their expanded forms in `@apply`, depending in the order of usage of the mixins, properties can be overridden. This means that using both `background-color: green;` and `background: red;` in two separate CSS selectors
+ can result in `background-color: transparent` in the selector that `background: red;` is specified.
+ 
+   ```css
+   #nonexistent {
+     --my-mixin: {
+       background: red;
+     }
+   }
+   ```
+   with an element style definition of
+   ```css
+   :host {
+     display: block;
+     background-color: green;
+     @apply(--my-mixin);
+   }
+   ```
+   results in the background being `transparent`, as an empty `background` definition replaces
+   the `@apply` definition. 
+ 
+   For this reason, we recommend avoiding shorthand properties.
+
+### Example:
+
+Here we define a block called `--mixin` at the document level, and apply that block to `my-element` somewhere in the page.
+
+```css
+html {
+  --mixin: {
+    border: 2px solid black;
+    background-color: green;
+  }
+}
+
+my-element {
+  border: 1px dotted orange;
+  @apply --mixin;
+}
+```
+
+becomes:
+
+```css
+html {
+  --mixin_-_border: 2px solid black;
+  --mixin_-_background-color: green;
+}
+
+my-element {
+  border: var(--mixin_-_border, 1px dotted orange);
+  background-color: var(--mixin_-_background-color);
+}
+```
+
+## About CustomStyleInterface
+
+CustomStyleInterface provides API to process `<style>` elements that are not inside of
+ShadowRoots, and simulate upper-boundary style scoping for ShadyDOM.
+
+To add document-level styles to ShadyCSS, one can call `CustomStyleInterface.addCustomStyle(styleElement)` or `CustomStyleInterface.addCustomStyle({getStyle: () => styleElement})`
+
+An example usage of the document-level styling api can be found in `examples/document-style-lib.js`, and another example that uses a custom element wrapper can be found in `examples/custom-style-element.js`
+
+### Example:
+
+```html
+<style class="document-style">
+html {
+  --content-color: brown;
+}
+</style>
+<my-element>This text will be brown!</my-element>
+<script>
+CustomStyleInterface.addCustomStyle(document.querySelector('style.document-style'));
+</script>
+```
+
+Another example with a wrapper `<custom-style>` element
+
+```html
+<custom-style>
+  <style>
+  html {
+    --content-color: brown;
+  }
+  </style>
+</custom-style>
+<script>
+class CustomStyle extends HTMLElement {
+  constructor() {
+    CustomStyleInterface.addCustomStyle(this);
+  }
+  getStyle() {
+    return this.querySelector('style');
+  }
+}
+</script>
+<my-element>This this text will be brown!</my-element>
+```
+
+Another example with a function that produces style elements
+
+```html
+<my-element>This this text will be brown!</my-element>
+<script>
+CustomStyleInterface.addCustomStyle({
+  getStyle() {
+    const s = document.createElement('style');
+    s.textContent = 'html{ --content-color: brown }';
+    return s;
+  }
+});
+</script>
+```
+
+## Usage
+
+To use ShadyCSS:
+
+1. First, call `ShadyCSS.prepareTemplate(template, name)` on a
+`<template>` element that will be imported into a `shadowRoot`.
+
+2. When the element instance is connected, call `ShadyCSS.styleElement(element)`
+
+3. Create and stamp the element's shadowRoot
+
+4. Whenever dynamic updates are required, call `ShadyCSS.styleSubtree(element)`.
+
+5. If a styling change is made that may affect the whole document, call
+`ShadyCSS.styleDocument()`.
+
+The following example uses ShadyCSS and ShadyDOM to define a custom element.
+
+```html
+<template id="myElementTemplate">
+  <style>
+    :host {
+      display: block;
+      padding: 8px;
+    }
+
+    #content {
+      background-color: var(--content-color);
+    }
+
+    .slot-container ::slotted(*) {
+      border: 1px solid steelblue;
+      margin: 4px;
+    }
+  </style>
+  <div id="content">Content</div>
+  <div class="slot-container">
+    <slot></slot>
+  </div>
+</template>
+<script>
+  // Use polyfill only in browsers that lack native Shadow DOM.
+  window.ShadyCSS && ShadyCSS.prepareTemplate(myElementTemplate, 'my-element');
+
+  class MyElement extends HTMLElement {
+    connectedCallback() {
+      window.ShadyCSS && ShadyCSS.styleElement(this);
+      if (!this.shadowRoot) {
+        this.attachShadow({mode: 'open'});
+        this.shadowRoot.appendChild(
+          document.importNode(myElementTemplate.content, true));
+      }
+    }
+  }
+
+  customElements.define('my-element', MyElement);
+</script>
+```
+
+## Type Extension elements
+
+ShadyCSS can also be used with type extension elements by supplying the base
+element name to `prepareTemplate` as a third argument.
+
+### Example
+
+```html
+<template id="myElementTemplate">
+  <style>
+    :host {
+      display: block;
+      padding: 8px;
+    }
+
+    #content {
+      background-color: var(--content-color);
+    }
+
+    .slot-container ::slotted(*) {
+      border: 1px solid steelblue;
+      margin: 4px;
+    }
+  </style>
+  <div id="content">Content</div>
+  <div class="slot-container">
+    <slot></slot>
+  </div>
+</template>
+<script>
+  window.ShadyCSS && ShadyCSS.prepareTemplate(myElementTemplate, 'my-element', 'div');
+
+  class MyElement extends HTMLDivElement {
+    connectedCallback() {
+      window.ShadyCSS && ShadyCSS.styleElement(this);
+      if (!this.shadowRoot) {
+        this.attachShadow({mode: 'open'});
+        this.shadowRoot.appendChild(
+          document.importNode(myElementTemplate.content, true));
+      }
+    }
+  }
+
+  customElements.define('my-element', MyElement, {extends: 'div'});
+</script>
+```
+
+## Imperative values for Custom properties
+
+To set the value of a CSS Custom Property imperatively, `ShadyCSS.styleSubtree`
+and `ShadyCSS.styleDocument` support an additional argument of an object mapping
+variable name to value.
+
+When using ApplyShim, defining new mixins or new values for current mixins imperatively is not
+supported.
+
+### Example
+```html
+<my-element id="a">Text</my-element>
+<my-element>Text</my-element>
+<script>
+let el = document.querySelector('my-element#a');
+// Set the color of all my-element instances to 'green'
+ShadyCSS.styleDocument({'--content-color' : 'green'});
+// Set the color my-element#a's text to 'red'
+ShadyCSS.styleSubtree(el, {'--content-color' : 'red'});
+</script>
+```
+
+## Limitations
+
+### Selector scoping
+
+To use the `::slotted` pseudo-element, you must select it as a descendant of some context element.
+```css
+/* Bad */
+::slotted() {}
+
+/* Good */
+.context ::slotted() {}
+```
+
+Since ShadyCSS removes all `<slot>` elements, you cannot select them directly or use any other selectors along with the `::slotted` pseudo-element selector.
+```html
+<!-- Bad -->
+<style>
+  .foo .bar::slotted(*) {}
+</style>
+<span class="foo">
+  <slot class="bar"></slot>
+</span>
+``` 
+
+```html
+<!-- Good -->
+<style>
+  .foo ::slotted(*) {}
+</style>
+<span class="foo">
+  <slot></slot>
+</span>
+``` 
+
+### Custom properties and `@apply`
+
+Dynamic changes are not automatically applied. If elements change such that they
+conditionally match selectors they did not previously, `ShadyCSS.styleDocument()`
+must be called.
+
+For a given element's shadowRoot, only 1 value is allowed per custom properties.
+Properties cannot change from parent to child as they can under native custom
+properties; they can only change when a shadowRoot boundary is crossed.
+
+To receive a custom property, an element must directly match a selector that
+defines the property in its host's stylesheet.
+
+### `<custom-style>` Flash of unstyled content
+
+If `ShadyCSS.applyStyle` is never called, `<custom-style>` elements will process
+after HTML Imports have loaded, after the document loads, or after the next paint.
+This means that there may be a flash of unstyled content on the first load.
+
+### Mixins do not cascade throught `<slot>`
+
+Crawling the DOM and updating styles is very expensive, and we found that trying to
+update mixins through `<slot>` insertion points to be too expensive to justify for both
+polyfilled CSS Mixins and polyfilled CSS Custom Properties.
+
+### External stylesheets not currently supported
+
+External stylesheets loaded via `<link rel="stylesheet">` within a shadow root or
+`@import` syntax inside a shadow root's stylesheet are not currently shimmed by
+the polyfill.  This is mainly due to the fact that shimming them would require
+a fetch of the stylesheet text that is async cannot be easily coordinated with
+the upgrade timing of custom elements using them, making it impossible to avoid
+"flash of unstyled content" when running on polyfill.
+
+### Document level styling is not scoped by default
+
+ShadyCSS mimics the behavior of shadow dom, but it is not able to prevent document
+level styling to affect elements inside a shady dom. Global styles defined in
+`index.html` or any styles not processed by ShadyCSS will affect all elements on the page.
+
+To scope document level styling, the style must be wrapped in the `<custom-style>` element
+found in Polymer, or use the `CustomStyleInterface` library to modify document level styles.
+
+### Dynamically created styles are not supported
+
+ShadyCSS works by processing a template for a given custom element class. Only the style
+elements present in that template will be scoped for the custom element's ShadowRoot.

This is accomplished by changing the property set to this:\n *\n *    --foo_-_border: 2px solid red;\n *    --foo_-_color: initial;\n *    --foo_-_background: initial;\n *\n * This works but introduces one new issue.\n * Consider this setup at the point where the `@apply` is used:\n *\n *    background: orange;\n *    `@apply` --foo;\n *\n * In this case the background will be unset (initial) rather than the desired\n * `orange`. We address this by altering the property set to use a fallback\n * value like this:\n *\n *    color: var(--foo_-_color);\n *    background: var(--foo_-_background, orange);\n *    border: var(--foo_-_border);\n *\n * Note that the default is retained in the property set and the `background` is\n * the desired `orange`. This leads us to a limitation.\n *\n * Limitation 1:\n\n * Only properties in the rule where the `@apply`\n * is used are considered as default values.\n * If another rule matches the element and sets `background` with\n * less specificity than the rule in which `@apply` appears,\n * the `background` will not be set.\n *\n * Limitation 2:\n *\n * When using Polymer's `updateStyles` api, new properties may not be set for\n * `@apply` properties.\n\n*/\n\n'use strict';\n\nimport {forEachRule, processVariableAndFallback, rulesForStyle, toCssText, gatherStyleText} from

+/*
+ * The apply shim simulates the behavior of `@apply` proposed at
+ * https://tabatkins.github.io/specs/css-apply-rule/.
+ * The approach is to convert a property like this:
+ *
+ *    --foo: {color: red; background: blue;}
+ *
+ * to this:
+ *
+ *    --foo_-_color: red;
+ *    --foo_-_background: blue;
+ *
+ * Then where `@apply --foo` is used, that is converted to:
+ *
+ *    color: var(--foo_-_color);
+ *    background: var(--foo_-_background);
+ *
+ * This approach generally works but there are some issues and limitations.
+ * Consider, for example, that somewhere *between* where `--foo` is set and used,
+ * another element sets it to:
+ *
+ *    --foo: { border: 2px solid red; }
+ *
+ * We must now ensure that the color and background from the previous setting
+ * do not apply. This is accomplished by changing the property set to this:
+ *
+ *    --foo_-_border: 2px solid red;
+ *    --foo_-_color: initial;
+ *    --foo_-_background: initial;
+ *
+ * This works but introduces one new issue.
+ * Consider this setup at the point where the `@apply` is used:
+ *
+ *    background: orange;
+ *    `@apply` --foo;
+ *
+ * In this case the background will be unset (initial) rather than the desired
+ * `orange`. We address this by altering the property set to use a fallback
+ * value like this:
+ *
+ *    color: var(--foo_-_color);
+ *    background: var(--foo_-_background, orange);
+ *    border: var(--foo_-_border);
+ *
+ * Note that the default is retained in the property set and the `background` is
+ * the desired `orange`. This leads us to a limitation.
+ *
+ * Limitation 1:
+
+ * Only properties in the rule where the `@apply`
+ * is used are considered as default values.
+ * If another rule matches the element and sets `background` with
+ * less specificity than the rule in which `@apply` appears,
+ * the `background` will not be set.
+ *
+ * Limitation 2:
+ *
+ * When using Polymer's `updateStyles` api, new properties may not be set for
+ * `@apply` properties.

+## Developer instructions
+
+### Setup
+
+1. Fork web-animations/web-animations-js.
+1. `git clone git@github.com:$GITHUB_USER/web-animations-js.git`
+1. `git submodule update --init --recursive` (Necessary for running tests.)
+1. Install [node](https://nodejs.org/en/) and make sure `npm` is in your $PATH
+1. Run `npm install` in the respository to pull in development dependencies.
+1. Run `npm install -g grunt-cli` to get the build tools for the command line.
+
+### Contributing
+
+Note that development should occur against the `dev` branch, not `master`. This
+is the default target for pull requests.
+
+1. In your fork of web-animations-js, `git checkout dev` or create a new branch whose parent is dev.
+1. Run `grunt` to build the polyfill.
+1. Run `grunt test` to run polyfill and web-platform-tests tests.
+1. Commit changes to your fork.
+1. Create a pull request from your fork of web-animations-js to
+   [web-animations/web-animations-js/dev](https://github.com/web-animations/web-animations-js/tree/dev).
+1. Ensure that you've signed the [Google Contributor License Agreement](https://cla.developers.google.com/clas).
+
+
+## Debugging tests
+
+You can run the tests in an interactive mode with `grunt debug`. This starts the
+Karma server once for each polyfill target for each test framework.
+Navigate to `http://localhost:9876/debug.html` to open the test runner in your
+browser of choice, all test results appear in the Javascript console.
+Test failures can be accessed via `window.failures` and `window.formattedFailures`
+once the tests have completed.
+
+The polyfill target and tests can be specified as arguments to the `debug` task.
+Example: `grunt debug:web-animations-next:test/web-platform-tests/web-animations/animation/pause.html`
+Multiple test files may be listed with comma separation. Specifying files will output their URL in the command line.
+Example: `http://localhost:9876/base/test/web-platform-tests/web-animations/animation/pause.html`

+## Design notes
+
+[Design diagrams](https://drive.google.com/folderview?id=0B9rpPoIDv3vTNlZxOVp6a2tNa1E&usp=sharing)
+
+
+## Publishing a release
+
+1.  Determine the version number for the release
+
+    * Increment the first number and reset others to 0 when there are large breaking changes
+    * Increment the second number and reset the third to 0 when there are significant new, but backwards compatible features
+    * Otherwise, increment the third number
+
+1.  Add versioned release notes to `History.md`, for example:
+
+        ### 3.13.37 — *November 1, 2001*
+
+          * Fixed a bug where nothing worked
+
+    Use the following to generate a summary of commits, but edit the list to contain only
+    relevant information.
+
+        git log --first-parent `git describe --tags --abbrev=0 master`..dev --pretty=format:"  * %s"
+
+1.  Specify the new version inside `package.json` (for NPM), for example:
+
+    ```js
+      "version": "3.13.37",
+    ```
+
+1.  Build the polyfill with `npm install && grunt` then update `docs/experimental.md`'s Build Target Comparison with the current gzipped sizes.
+
+1.  Commit the above changes to web-animations-js/dev and merge to
+    web-animations-js/master.
+
+    ```sh
+    git checkout master
+    git merge dev --no-edit --quiet
+    ```
+
+1.  Build and commit minified JavaScript files.
+
+    ```sh
+    npm install
+    grunt
+    # Optional "grunt test" to make sure everything still passes.
+    git add -f *.min.js{,.map}
+    git rm .gitignore
+    git commit -m 'Add build artifacts from '`cat .git/refs/heads/dev`
+    git push HEAD:refs/heads/master
+    ```
+
+1.  Draft a [new release](https://github.com/web-animations/web-animations-js/releases) at the
+    commit pushed to web-animations-js in step #4. Copy the release notes from `History.md`
+    added in step #2.
+
+1. Once you've pushed to web-animations-js, run `npm publish` from that checked-out folder
+
+   To do this, you'll need to be a collaborator [on the NPM project](https://www.npmjs.com/package/web-animations-js), or have a collaborator help you.
+
+1. If there are any breaking changes to the API in this release you must notify web-animations-changes@googlegroups.com.
+
+   Only owners of the group may post to it so you may need to request ownership or ask someone to post it for you.
+
+## Testing architecture
+
+This is an overview of what happens when `grunt test` is run.
+
+1. Polyfill tests written in mocha and chai are run.
+    1. grunt creates a karma config with mocha and chai adapters.
+    1. grunt adds the test/js files as includes to the karma config.
+    1. grunt starts the karma server with the config and waits for the result.
+    1. The mocha adaptor runs the included tests and reports the results to karma.
+    1. karma outputs results to the console and returns the final pass/fail result to grunt.
+1. web-platform-tests/web-animations tests written in testtharness.js are run.
+    1. grunt creates a karma config with karma-testharness-adaptor.js included.
+    1. grunt adds the web-platform-tests/web-animations files to the custom testharnessTests config in the karma config.
+    1. grunt adds failure expectations to the custom testharnessTests config in the karma config.
+    1. grunt starts the karma server with the config and waits for the result.
+    1. The testharness.js adaptor runs the included tests (ignoring expected failures) and reports the results to karma.
+    1. karma outputs results to the console and returns the final pass/fail result to grunt.
+1. grunt exits successfully if both test runs passed.

+
+    For example, this is deprecated and will eventually throw a TypeError:
+
+        element.animate([], {
+            duration: -1,
+            iterationStart: -1,

+
+### 2.2.0 - *April 6 2016*
+  * Deprecated the use of hyphens in property names.
+
+    For example, this is deprecated:

+
+    and this should be used instead:
+
+        element.animate([{fontSize: '0px'}, {fontSize: '10px'}]);

+
+        element.animate({color: ['red', 'green', 'blue']});
+
+  * Fixed easing TypeError in FireFox Nightly when using groups.
+
+  * Fixed delayed animation updates on Safari and Firefox

+  * Add Animation.timeline getter
+  * Add AnimationEffect.parent getter
+  * Make AnimationEffectTiming (returned by AnimationEffect.timing) attributes mutable
+  * Expose the Animation constructor
+  * Change custom effects from AnimationEffects to onsample functions. Custom effects should now be created by setting the onsample attribute of a KeyframeEffect.
+
+    For example, this is deprecated:
+
+        var myEffect = new KeyframeEffect(
+           element,
+           function(timeFraction, target, effect) {
+              target.style.opacity = timeFraction;
+           },
+           1000);
+        var myAnimation = document.timeline.play(myEffect);
+
+    and this should be used insead:
+
+        var myEffect = new KeyframeEffect(element, [], 1000);
+        effect.onsample = function(timeFraction, effect, animation) {
+           effect.target.style.opacity = timeFraction;
+        };
+        var myAnimation = document.timeline.play(myEffect);
+

+  * Rename Element.getAnimationPlayers to Element.getAnimations.
+
+### 1.0.7 - *March 10 2015*

+
+  * Fix loading the polyfill in an SVG document
+  * Fix a problem where groups didn't take effect in their first frame
+  * Don't rely on performance.now
+
+### 1.0.4 - *December 8 2014*
+
+  * Fix a critical bug where deprecation logic wasn't being loaded
+    when `web-animations-next` and `web-animations-next-lite` were
+    executed on top of a native `element.animate`.
+
+### 1.0.3 - *December 4 2014*
+
+  * Fix a critical bug on iOS 7 and Safari <= 6. Due to limitations,
+    inline style patching is not supported on these platforms.

+
+### 1.0.0 — *November 21 2014*
+
+  The web-animations-js hackers are pleased to announce the release of
+  a new codebase for the Web Animations Polyfill:
+  https://github.com/web-animations/web-animations-js
+
+  The previous polyfill has been moved to:
+  https://github.com/web-animations/web-animations-js-legacy
+
+  The new codebase is focused on code-size -- our smallest target is
+  now only 33kb or 11kb after gzip.
+
+  We've implemented native fallback. If the target browser provides
+  Web Animations features natively, the Polyfill will use them.
+
+  We now provide three different build targets:
+
+  `web-animations.min.js` - Tracks the Web Animations features that
+  are supported natively in browsers. Today that means Element.animate
+  and Playback Control in Chrome. If you’re not sure what features you
+  will need, start with this.
+
+  `web-animations-next.min.js` - All of web-animations.min.js plus
+  features that are still undergoing discussion or have yet to be
+  implemented natively.
+
+  `web-animations-next-lite.min.js` - A cut down version of
+  web-animations-next, removes several lesser used property handlers
+  and some of the larger and less used features such as matrix
+  interpolation/decomposition.
+
+  Not all features of the previous polyfill have been ported to the
+  new codebase; most notably mutation of Animations and Groups and
+  Additive Animations are not yet supported. These features are still
+  important and will be implemented in the coming weeks.

+
+What is Web Animations?
+-----------------------
+
+A new JavaScript API for driving animated content on the web. By unifying
+the animation features of SVG and CSS, Web Animations unlocks features
+previously only usable declaratively, and exposes powerful, high-performance
+animation capabilities to developers.
+
+What is in this repository?
+---------------------------
+
+A JavaScript implementation of the Web Animations API that provides Web
+Animation features in browsers that do not support it natively. The polyfill
+falls back to the native implementation when one is available.
+
+Quick start
+-----------
+
+Here's a simple example of an animation that fades and scales a `<div>`.  
+[Try it as a live demo.](http://jsbin.com/yageyezabo/edit?html,js,output)
+
+```html
+<!-- Include the polyfill -->
+<script src="web-animations.min.js"></script>
+
+<!-- Set up a target to animate -->
+<div class="pulse" style="width: 150px;">Hello world!</div>
+
+<!-- Animate! -->
+<script>
+    var elem = document.querySelector('.pulse');
+    var animation = elem.animate({
+        opacity: [0.5, 1],
+        transform: ['scale(0.5)', 'scale(1)'],
+    }, {
+        direction: 'alternate',
+        duration: 500,
+        iterations: Infinity,
+    });
+</script>
+```

+#Examples of using Web Animations
+
+Property indexed keyframes syntax
+---------------------------------
+- Each CSS property specifies its keyframe values as a list, different properties may have differently sized lists.
+- The `easing` property applies its timing function to all keyframes.
+
+[**Live demo**](http://jsbin.com/qiyeriruru/edit?js,output)
+```javascript
+element.animate({
+  transform: [
+    'scaleY(0.5)',
+    'scaleX(0.5)',
+    'scaleY(0.5)',
+  ],
+  background: [
+    'red',
+    'blue',
+    'orange',
+    'red',
+  ],
+  easing: 'ease-in-out',
+}, {
+  duration: 2000,
+  iterations: Infinity,
+});
+```
+
+Keyframe list syntax
+--------------------
+- Keyframes can be specified as a list of multiple CSS property values.
+- Individual keyframes can be given specific offsets and easings.
+- Not all properties need to be specified in every keyframe.
+- Offsets are implicitly distributed if not specified.
+
+[**Live demo**](http://jsbin.com/yajatoyere/edit?js,output)
+```javascript
+element.animate([
+  {
+    background: 'red',
+    transform: 'none',
+    easing: 'ease-out',
+  },
+  {
+    offset: 0.1,
+    transform: 'translateY(100px)',
+    easing: 'ease-in-out',
+  },
+  {
+    offset: 0.2,
+    transform: 'translate(100px, 100px)',
+    easing: 'ease-in-out',
+  },
+  {
+    offset: 0.4,
+    transform: 'translateX(100px)',
+    easing: 'ease-out',
+  },
+  {
+    background: 'blue',
+    transform: 'none',
+  },
+], {
+  duration: 4000,
+  iterations: Infinity,
+});
+```
+
+Timing parameters
+-----------------
+- Web Animations inherits many of its timing parameters from CSS Animations.
+- See the [specification](http://w3c.github.io/web-animations/#animationeffecttimingreadonly) for details on each parameter.
+
+[**Live demo**](http://jsbin.com/dabehipiyo/edit?js,output)
+```javascript
+element.animate({
+  transform: ['none', 'translateX(100px)'],
+  background: ['green', 'lime'],
+}, {
+  // Apply effect during delay.
+  fill: 'backwards',
+
+  // Delay starting by 500ms.
+  delay: 500,
+
+  // Iterations last for 2000ms.
+  duration: 2000,
+
+  // Start at 25% through an iteration.
+  iterationStart: 0.25,
+
+  // Run for 2 iterations.
+  iterations: 2,
+
+  // Play every second iteration backwards.
+  direction: 'alternate',
+
+  // Stop animating 500ms earlier.
+  endDelay: -500,
+
+  // The timing function to use with each iteration.
+  easing: 'ease-in-out',
+});
+```
+
+Playback controls
+-----------------
+- element.animate() returns an Animation object with basic playback controls.
+- See the [specification](http://w3c.github.io/web-animations/#the-animation-interface) for details on each method.
+
+[**Live demo**](http://jsbin.com/kutaqoxejo/edit?js,output)
+```javascript
+var animation = element.animate({
+  transform: ['none', 'translateX(200px)'],
+  background: ['red', 'orange'],
+}, {
+  duration: 4000,
+  fill: 'both',
+});
+animation.play();
+animation.reverse();
+animation.pause();
+animation.currentTime = 2000;
+animation.playbackRate += 0.25;
+animation.playbackRate -= 0.25;
+animation.finish();
+animation.cancel();
+```
+
+Transitioning states with element.animate()
+-------------------------------------------
+- This is an example of how to animate from one state to another using Web Animations.
+
+[**Live demo**](http://jsbin.com/musufiwule/edit?js,output)
+```javascript
+var isOpen = false;
+var openHeight = '100px';
+var closedHeight = '0px';
+var duration = 300;
+
+button.addEventListener('click', function() {
+  // Prevent clicks while we transition states.
+  button.disabled = true;
+  button.textContent = '...';
+
+  // Determine where we're animation from/to.
+  var fromHeight = isOpen ? openHeight : closedHeight;
+  var toHeight = isOpen ? closedHeight : openHeight;
+
+  // Start an animation transitioning from our current state to the final state.
+  var animation = element.animate({ height: [fromHeight, toHeight] }, duration);
+
+  // Update the button once the animation finishes.
+  animation.onfinish = function() {
+    isOpen = !isOpen;
+    button.textContent = isOpen ? 'Close' : 'Open';
+    button.disabled = false;
+  };
+
+  // Put our element in the final state.
+  // Inline styles are overridden by active animations.
+  // When the above animation finishes it will stop applying and
+  // the element's style will fall back onto this inline style value.
+  element.style.setProperty('height', toHeight);
+});
+```
+
+Generating animations
+---------------------
+- The Javascript API allows for procedurally generating a diverse range of interesting animations.
+
+[**Live demo**](http://jsbin.com/xolacasiyu/edit?js,output)

+Experimental build targets
+--------------------------
+
+Most people should use the basic polyfill in `web-animations.min.js`. This
+tracks the Web Animations features that are supported natively in browsers.
+However, we also provide two additional build targets that contain experimental
+features.
+
+### web-animations-next.min.js
+
+Contains all of web-animations.min.js plus features that are still undergoing
+discussion or have yet to be implemented natively.
+
+### web-animations-next-lite.min.js
+
+A cut down version of web-animations-next, it removes several lesser used
+property handlers and some of the larger and less used features such as matrix
+interpolation/decomposition.

+
+Caveat: Inline style
+--------------------
+
+Inline style modification is the mechanism used by the polyfill to animate
+properties. Both web-animations and web-animations-next incorporate a module
+that emulates a vanilla inline style object, so that style modification from
+JavaScript can still work in the presence of animations. However, to keep the
+size of web-animations-next-lite as small as possible, the style emulation
+module is not included. When using this version of the polyfill, JavaScript
+inline style modification will be overwritten by animations.
+Due to browser constraints inline style modification is not supported on iOS 7
+or Safari 6 (or earlier versions).

+
+Getting the polyfill
+--------------------
+
+There are three ways to get a copy of the polyfill:
+
+1. Download and use the `web-animations.min.js` file directly from this repository
+1. Using npm: Add [`web-animations-js`](https://www.npmjs.com/package/web-animations-js) to your `package.json`
+1. Using Bower: Add `web-animations/web-animations-js` to your `bower.json`
+
+Browser support
+---------------
+
+The polyfill is supported on modern versions of all major browsers, including:
+
+* Chrome 55+
+* Firefox 27+
+* IE10+ (including Edge)
+* Safari (iOS) 7.1+
+* Safari (Mac) 9+
+
+Native fallback
+---------------
+
+When the polyfill runs on a browser that implements `Element.animate()` and
+`Animation` playback control, it will detect and use the underlying native
+features for better performance.
+
+Features
+--------
+
+The `web-animations.min.js` polyfill target tracks the Web Animations features
+that are supported natively in browsers. These include:
+
+* Element.animate()
+* Timing input (easings, duration, fillMode, etc.) for animation effects
+* Playback control (play, pause, reverse, currentTime, cancel, onfinish)
+* Support for animating CSS properties
+
+Caveat: Prefix handling
+-----------------------
+
+The polyfill will automatically detect the correctly prefixed name to use when
+writing animated properties back to the platform. Where possible, the polyfill
+will only accept unprefixed versions of experimental features. For example:
+
+```js
+element.animate({transform: ['none', 'translateX(100px)']}, 1000);
+```
+
+will work in all browsers that implement a conforming version of transform, but
+
+```js
+element.animate({webkitTransform: ['none', 'translateX(100px)']}, 1000);
+```
+
+will not work anywhere.
+
+Process for breaking changes
+----------------------------
+
+When we make a potentially breaking change to the polyfill's API
+surface (like a rename) we will, where possible, continue supporting the
+old version, deprecated, for three months, and ensure that there are
+console warnings to indicate that a change is pending. After three
+months, the old version of the API surface (e.g. the old version of a
+function name) will be removed. *If you see deprecation warnings, you
+can't avoid them by not updating*.

+webcomponents.js
+================
+
+[![Build Status](https://travis-ci.org/webcomponents/webcomponentsjs.svg?branch=master)](https://travis-ci.org/webcomponents/webcomponentsjs)
+
+A suite of polyfills supporting the [Web Components](http://webcomponents.org) specs:
+
+**Custom Elements**: allows authors to define their own custom tags ([spec](https://w3c.github.io/webcomponents/spec/custom/)).
+
+**HTML Imports**: a way to include and reuse HTML documents via other HTML documents ([spec](https://w3c.github.io/webcomponents/spec/imports/)).
+
+**Shadow DOM**: provides encapsulation by hiding DOM subtrees under shadow roots ([spec](https://w3c.github.io/webcomponents/spec/shadow/)).
+
+This also folds in polyfills for `MutationObserver` and `WeakMap`.
+
+
+## Releases
+
+Pre-built (concatenated & minified) versions of the polyfills are maintained in the [tagged versions](https://github.com/webcomponents/webcomponentsjs/releases) of this repo. There are two variants:
+
+`webcomponents.js` includes all of the polyfills.
+
+`webcomponents-lite.js` includes all polyfills except for shadow DOM.
+
+
+## Browser Support
+
+Our polyfills are intended to work in the latest versions of evergreen browsers. See below
+for our complete browser support matrix:
+
+| Polyfill   | IE10 | IE11+ | Chrome* | Firefox* | Safari 7+* | Chrome Android* | Mobile Safari* |
+| ---------- |:----:|:-----:|:-------:|:--------:|:----------:|:---------------:|:--------------:|
+| Custom Elements | ~ | ✓ | ✓ | ✓ | ✓ | ✓| ✓ |
+| HTML Imports | ~ | ✓ | ✓ | ✓ | ✓| ✓| ✓ |
+| Shadow DOM | ✓ | ✓ | ✓ | ✓ | ✓ | ✓ | ✓ |
+| Templates | ✓ | ✓ | ✓ | ✓| ✓ | ✓ | ✓ |
+
+
+*Indicates the current version of the browser
+
+~Indicates support may be flaky. If using Custom Elements or HTML Imports with Shadow DOM,
+you will get the non-flaky Mutation Observer polyfill that Shadow DOM includes.
+
+The polyfills may work in older browsers, however require additional polyfills (such as classList)
+to be used. We cannot guarantee support for browsers outside of our compatibility matrix.
+
+
+### Manually Building
+
+If you wish to build the polyfills yourself, you'll need `node` and `gulp` on your system:
+
+ * install [node.js](http://nodejs.org/) using the instructions on their website
+ * use `npm` to install [gulp.js](http://gulpjs.com/): `npm install -g gulp`
+
+Now you are ready to build the polyfills with:
+
+    # install dependencies
+    npm install
+    # build
+    gulp build
+
+The builds will be placed into the `dist/` directory.

+
+## Helper utilities
+
+### `WebComponentsReady`
+
+Under native HTML Imports, `<script>` tags in the main document block the loading of such imports. This is to ensure the imports have loaded and any registered elements in them have been upgraded. 
+
+The webcomponents.js and webcomponents-lite.js polyfills parse element definitions and handle their upgrade asynchronously. If prematurely fetching the element from the DOM before it has an opportunity to upgrade, you'll be working with an `HTMLUnknownElement`. 
+
+For these situations (or when you need an approximate replacement for the Polymer 0.5 `polymer-ready` behavior), you can use the `WebComponentsReady` event as a signal before interacting with the element. The criteria for this event to fire is all Custom Elements with definitions registered by the time HTML Imports available at load time have loaded have upgraded.
+
+```js
+window.addEventListener('WebComponentsReady', function(e) {
+  // imports are loaded and elements have been registered
+  console.log('Components are ready');
+});
+```
+
+## Known Issues
+
+  * [Limited CSS encapsulation](#encapsulation)
+  * [Element wrapping / unwrapping limitations](#wrapping)
+  * [Custom element's constructor property is unreliable](#constructor)
+  * [Contenteditable elements do not trigger MutationObserver](#contentedit)
+  * [ShadowCSS: :host-context(...):host(...) doesn't work](#hostcontext)
+  * [ShadowCSS: :host(.zot:not(.bar:nth-child(2))) doesn't work](#nestedparens)
+  * [HTML imports: document.currentScript doesn't work as expected](#currentscript)
+  * [execCommand isn't supported under Shadow DOM](#execcommand)
+
+### Limited CSS encapsulation <a id="encapsulation"></a>
+Under native Shadow DOM, CSS selectors cannot cross the shadow boundary. This means document level styles don't apply to shadow roots, and styles defined within a shadow root don't apply outside of that shadow root. [Several selectors](http://www.html5rocks.com/en/tutorials/webcomponents/shadowdom-201/) are provided to be able to deal with the shadow boundary.
+
+The Shadow DOM polyfill can't prevent document styles from leaking into shadow roots. It can, however, encapsulate styles within shadow roots to some extent. This behavior isn't automatically emulated by the Shadow DOM polyfill, but it can be achieved by manually using the included ShadowCSS shim:
+
+```
+WebComponents.ShadowCSS.shimStyling( shadowRoot, scope );
+```
+
+... where `shadowRoot` is the shadow root of a DOM element, and `scope` is the name of the scope used to prefix the selectors. This removes all `<style>` elements from the shadow root, rewrites it rules using the given scope and reinserts the style as a document level stylesheet. Note that the `:host` and `:host-context` pseudo classes are also rewritten.
+
+For a full explanation on the implementation and both the possibilities and the limitations of ShadowCSS please view the documentation in the [ShadowCSS source](src/ShadowCSS/ShadowCSS.js).
+
+### Element wrapping / unwrapping limitations <a id="wrapping"></a>
+The Shadow DOM polyfill is implemented by [wrapping](http://webcomponents.org/polyfills/shadow-dom/#wrappers) DOM elements whenever possible. It does this by wrapping methods like `document.querySelector` to return wrapped DOM elements. This has a few caveats:
+   * Not _everything_ can be wrapped. For example, elements like `document`, `window`, `document.body`, `document.fullscreenElement` and others are non-configurable and thus cannot be overridden.
+   * Wrappers don't support [live NodeLists](https://developer.mozilla.org/en-US/docs/Web/API/NodeList#A_sometimes-live_collection) like `HTMLElement.childNodes` and `HTMLFormElement.elements`. All NodeLists are snapshotted upon read. See [#217](https://github.com/webcomponents/webcomponentsjs/issues/217) for an explanation.
+
+In order to work around these limitations the polyfill provides the `ShadowDOMPolyfill.wrap` and `ShadowDOMPolyfill.unwrap` methods to respectively wrap and unwrap DOM elements manually.
+
+### Custom element's constructor property is unreliable <a id="constructor"></a>
+See [#215](https://github.com/webcomponents/webcomponentsjs/issues/215) for background.
+
+In Safari and IE, instances of Custom Elements have a `constructor` property of `HTMLUnknownElementConstructor` and `HTMLUnknownElement`, respectively. It's unsafe to rely on this property for checking element types.
+
+It's worth noting that `customElement.__proto__.__proto__.constructor` is `HTMLElementPrototype` and that the prototype chain isn't modified by the polyfills(onto `ElementPrototype`, etc.)
+
+### Contenteditable elements do not trigger MutationObserver <a id="contentedit"></a>
+Using the MutationObserver polyfill, it isn't possible to monitor mutations of an element marked `contenteditable`.
+See [the mailing list](https://groups.google.com/forum/#!msg/polymer-dev/LHdtRVXXVsA/v1sGoiTYWUkJ)
+
+### ShadowCSS: :host-context(...):host(...) doesn't work <a id="hostcontext"></a>
+See [#16](https://github.com/webcomponents/webcomponentsjs/issues/16) for background.
+
+Under the shadow DOM polyfill, rules like:
+```
+:host-context(.foo):host(.bar) {...}
+```
+don't work, despite working under native Shadow DOM. The solution is to use `polyfill-next-selector` like:
+
+```
+polyfill-next-selector { content: '.foo :host.bar, :host.foo.bar'; }
+```
+
+### ShadowCSS: :host(.zot:not(.bar:nth-child(2))) doesn't work <a id="nestedparens"></a>
+ShadowCSS `:host()` rules can only have (at most) 1-level of nested parentheses in its argument selector under ShadowCSS. For example, `:host(.zot)` and `:host(.zot:not(.bar))` both work, but `:host(.zot:not(.bar:nth-child(2)))` does not. 
+
+### HTML imports: document.currentScript doesn't work as expected <a id="currentscript"></a>
+In native HTML Imports, document.currentScript.ownerDocument references the import document itself. In the polyfill use document._currentScript.ownerDocument (note the underscore).
+
+### execCommand and contenteditable isn't supported under Shadow DOM <a id="execcommand"></a>
+See [#212](https://github.com/webcomponents/webcomponentsjs/issues/212)
+
+`execCommand`, and `contenteditable` aren't supported under the ShadowDOM polyfill, with commands that insert or remove nodes being especially prone to failure.
