title: Dismissable alert
body: <p>I'm trying to get an alert to disappear when the "x" button is clicked, but there seems to be something missing that's keeping it from working, not sure what it is.</p>
  
  <pre><code>&lt;div class="alert alert-success alert-dismissible"&gt;
  &lt;button type = "button" class="close" data-dismiss = "alert"&gt;x&lt;/button&gt;
      You've done it!
  &lt;/div&gt;
  </code></pre>
