      <h2 class="ui dividing header">Introduction</h2>

      <p>UI Transitions provide a wrapper for using css transitions in javascript providing cross-browser callbacks, advanced queuing, and feature detection.</p>
      <p>Transitions are loosely coupled with other ui modules like <a href="/modules/dropdown.html">dropdowns</a> and <a href="/modules/modal.html">modals</a> to provide element transitions</p>

      <h3 class="ui header">Types</h3>
      <p>Transitions are separated into three categories. <b>Inward transitions</b>, <b>outward transitions</b>, and <b>static transitions</b>. These three categories determine the visibility of the element after the animation completes.</p>

      <h2 class="ui dividing header">Usage</h2>

      <h3 class="ui header">Initializing</h3>

      <p>If a transition is called without any arguments all default settings will be used.</p>

      <div class="code" data-demo="true" data-title="Initializing a transition">
      $('.dog.image')
        // default everything
        .transition()
      ;
      </div>

      <h3 class="ui header">Passing in settings</h3>
      <p>Transitions use similar argument shorthand as <a href="http://api.jquery.com/animate/">animate</a>. You can specify callback functions, animation duration, and other settings using the same arguments. Durations can be specified as strings with css shorthand, or with numbers.</p>
      <div class="code" data-demo="true" data-title="Settings objects">
      $('.dog.image')
        .transition({
          animation : 'scale',
          duration  : '2s',
          complete  : function() {
            alert('done');
          }
        })
      ;
      </div>

      <h3 class="ui header">Queuing animations</h3>

      <p>Animations called in sequence will be queued. Any queued animation will automatically determine the transition direction if none is specified.</p>
      <div class="code" data-demo="true" data-title="Queueing animations">
      $('.dog.image')
        .transition('horizontal flip', '500ms')
        .transition('horizontal flip', 500, function() {
          alert('done!');
        })
      ;
      </div>
      <h2 class="ui dividing header">Behavior</h2>

      <p>All the following <a href="/module.html#/behavior">behaviors</a> can be called using the syntax:</p>
      <div class="code">
      $('.your.element')
        .dropdown('behavior name', argumentOne, argumentTwo)
      ;
      </div>
