title: Are the featurette classes in Bootstrap 3 in css by default, or do I have to add them manually?
body: <p>I am trying to copy the typography from the featurette section on <a href="http://getbootstrap.com/examples/carousel/" rel="nofollow">this</a> page. I put all the featurette classes in, but all that shows up is the featurette-divider.</p>
  
  <p>Here is my html</p>
  
  <pre><code>&lt;!doctype html&gt;
  &lt;html lang="en"&gt;
  &lt;head&gt;
      &lt;meta charset="UTF-8"&gt;
      &lt;title&gt;Mockup&lt;/title&gt;
      &lt;?php include 'inc/head.php'; ?&gt;
  &lt;/head&gt;
  &lt;body&gt;
  
      &lt;div class="container"&gt;
          &lt;div class="row"&gt;
              &lt;div class="col-md-12"&gt;
                  &lt;hr class="featurette-divider"&gt;
                  &lt;div class="featurette featurette-shadow"&gt;
                      &lt;h2 class="featurette-heading"&gt;Testing 1...2...3... &lt;span class="text-muted"&gt;Lets Go!&lt;/span&gt;&lt;/h2&gt;
                  &lt;/div&gt;
              &lt;/div&gt;
          &lt;/div&gt;
      &lt;/div&gt;
  
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>Thank you!</p>
