-Material Design: <a href="http://www.google.com/design/spec/components/buttons.html">Buttons</a>
-
-`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>
-
-### Styling
-
-Style the button with CSS as you would a normal DOM element.
-
-    /* make #my-button green with yellow text */
-    #my-button {
-        background: green;
-        color: yellow;
-    }
-
-By default, the ripple is the same color as the foreground at 25% opacity. You may
-customize the color using this selector:
-
-    /* make #my-button use a blue ripple instead of foreground color */
-    #my-button::shadow paper-ripple {
-      color: blue;
-    }
-
-The opacity of the ripple is not customizable via CSS.
-
-The following custom properties and mixins are also available for styling:
-
-Custom property | Description | Default
-----------------|-------------|----------
-`--paper-button-flat-focus-color` | Background color of a focused flat button | `--paper-grey-200`
-`--paper-button` | Mixin applied to the button | `{}`
-`--paper-button-disabled` | Mixin applied to the disabled button | `{}`
