-paper-icon-button
-=================
-
-Material Design: <a href="http://www.google.com/design/spec/components/buttons.html">Buttons</a>
-
-`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
-<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:
-
-```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>
-```
-
-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 this selector:
-
-```css
-/* make #my-button use a blue ripple instead of foreground color */
-#my-button::shadow #ripple {
-  color: blue;
-}
-```
-
-The opacity of the ripple is not customizable via CSS.
