##&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`.
