    <h1>Simple</h1>
    <p>To activate the scroll glue on an element just add the scroll-glue attribute.</p>
    <pre>&lt;div scroll-glue/&gt;</pre>
    <div scroll-glue>
      <ul>
        <li ng-repeat="item in items">{{item}}</li>
      </ul>
    </div>

    <h1>With two-way data binding</h1>
    <p>If you pass a scope variable to the attribute, scroll-glue updates the variable to true when the glue is attached or to false if the glue is released and activates/deactivates the glue according to the variables value.</p>
    <pre>&lt;div scroll-glue="glued"/&gt;</pre>
    <div scroll-glue="glued">
      <ul>
        <li ng-repeat="item in items">{{item}}</li>
      </ul>
    </div>
    <p><button ng-click="glued = !glued">Toggle glued ({{glued}})</button></p>

    <h1>With one-way data binding</h1>
    <p>If you pass an expression that is not a scope variable, the scroll-glue is bound to the result of this expression.</p>
    <pre>&lt;div scroll-glue="!glued"/&gt;</pre>
    <div scroll-glue="!glued">
      <ul>
        <li ng-repeat="item in items">{{item}}</li>
      </ul>
    </div>
    <p>If you want to force one way-binding on a scope variable use double negation:</p>
    <pre>&lt;div scroll-glue="!!glued"/&gt;</pre>

    <h1>Scroll Direction</h1>
    <p>You can also specify the scroll direction by combining the following directives:</p>
      <pre>&lt;div scroll-glue-top="glued"/&gt;</pre>
      <div scroll-glue-top="glued">
        <ul>
          <li ng-repeat="item in items.slice().reverse()">{{item}}</li>
        </ul>
      </div>
      <pre>&lt;div scroll-glue-bottom="glued"/&gt;</pre>
      <div scroll-glue-bottom="glued">
        <ul>
          <li ng-repeat="item in items">{{item}}</li>
        </ul>
      </div>
      <pre>&lt;div scroll-glue-left="glued"/&gt;</pre>
      <div scroll-glue-left="glued">
        <span ng-repeat="item in items.slice().reverse()">{{item}}</span>
      </div>
      <pre>&lt;div scroll-glue-right="glued"/&gt;</pre>
      <div scroll-glue-right="glued">
        <span ng-repeat="item in items">{{item}}</span>
      </div>
  </body>
