  <div class="ui tab" data-tab="usage">

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

    <h3 class="ui header">Display</h3>
    <p>You can display a dimmer by either invoking dimmer show on a section or a dimmer itself. If you choose to dim a dimmable section, a dimmer will automatically be created.</p>
    <div class="ignore code">
    // these two are the same
    $('.ui.dimmable)
      .dimmer('show')
    ;
    $('.ui.dimmable .dimmer')
      .dimmer('show')
    ;
    </div>

    <h3 class="ui header">Creating Dimmers</h3>
    <p>If a dimmer does not exist inside the element it will be created on first use.</p>
    <div class="code" data-demo="true">
      $('h3')
        .dimmer('toggle')
      ;
    </div>
    <h3 class="ui header">Showing a specific dimmer</h3>
    <p>If a dimmer is already inside an element, you can call behavior on the dimmable section or the dimmer itself.</p>
    <div class="code" data-demo="true">
      // If a dimmer exists on a page, you can make it appear by calling it directly
      $('.page.dimmer:first')
        .dimmer('toggle')
      ;
    </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>
