-`paper-tabs` makes it easy to explore and switch between different views or functional aspects of
-an app, or to browse categorized data sets.
-
-Use `selected` property to get or set the selected tab.
-
-Example:
-
-    <paper-tabs selected="0">
-      <paper-tab>TAB 1</paper-tab>
-      <paper-tab>TAB 2</paper-tab>
-      <paper-tab>TAB 3</paper-tab>
-    </paper-tabs>
-
-See <a href="#paper-tab">paper-tab</a> for more information about
-`paper-tab`.
-
-A common usage for `paper-tabs` is to use it along with `iron-pages` to switch
-between different views.
-
-    <paper-tabs selected="{{selected}}">
-      <paper-tab>Tab 1</paper-tab>
-      <paper-tab>Tab 2</paper-tab>
-      <paper-tab>Tab 3</paper-tab>
-    </paper-tabs>
-
-    <iron-pages selected="{{selected}}">
-      <div>Page 1</div>
-      <div>Page 2</div>
-      <div>Page 3</div>
-    </iron-pages>
-
-
-To use links in tabs, add `link` attribute to `paper-tab` and put an `<a>`
-element in `paper-tab`.
-
-Example:
-
-    <paper-tabs selected="0">
-      <paper-tab link>
-        <a href="#link1" class="horizontal center-center layout">TAB ONE</a>
-      </paper-tab>
-      <paper-tab link>
-        <a href="#link2" class="horizontal center-center layout">TAB TWO</a>
-      </paper-tab>
-      <paper-tab link>
-        <a href="#link3" class="horizontal center-center layout">TAB THREE</a>
-      </paper-tab>
-    </paper-tabs>
-
-### Styling
-
-The following custom properties and mixins are available for styling:
-
-Custom property | Description | Default
-----------------|-------------|----------
-`--paper-tabs-selection-bar-color` | Color for the selection bar | `--paper-yellow-a100`
-`--paper-tabs` | Mixin applied to the tabs | `{}`
