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.
