 paper-fab
 =========
 
 Material Design: <a href="http://www.google.com/design/spec/components/buttons.html">Button</a>
 
 `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:
 
 ```html
 <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
--------
-
-Style the button with CSS as you would a normal DOM element. If you are using the icons
-provided by `iron-icons`, the icon will inherit the foreground color of the button.
-
-```html
-<!-- make a blue "cloud" button -->
-<paper-fab icon="cloud" style="color: blue;"></paper-fab>
-```
-
-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.
