 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:
 
     <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.
+### Styling
 
-    /* make a blue "cloud" button */
-    <paper-fab icon="cloud" style="color: blue;"></paper-fab>
+The following custom properties and mixins are available for styling:
 
-By default, the ripple is the same color as the foreground at 25% opacity. You may
-customize the color using this selector:
+Custom property | Description | Default
+----------------|-------------|----------
+`--paper-fab-background` | The background color of the button | `--paper-indigo-500`
+`--paper-fab-disabled-background` | The background color of the button when it's disabled | `--paper-grey-300`
+`--paper-fab-disabled-text` | The text color of the button when it's disabled | `--paper-grey-500`
+`--paper-fab` | Mixin applied to the button | `{}`
+`--paper-fab-mini` | Mixin applied to a mini button | `{}`
+`--paper-fab-disabled` | Mixin applied to a disabled button | `{}`
 
-    /* make #my-button use a blue ripple instead of foreground color */
-    #my-button::shadow #ripple {
-      color: blue;
-    }
