title: Bootstrap Jumbotron Class Not Rendering Grey Highlight
body: <p>I'm learning to code, and my Jumbotron class in Bootstrap isn't rendering the grey highlight at all. Can someone please take a look at it and tell me what I'm doing wrong?</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;div class="Jumbotron"&gt;
    &lt;h1&gt;This is a Jumbotron&lt;/h1&gt;
    &lt;p&gt;Bacon ipsum dolor amet pastrami shankle jerky tail, ground round hamburger sausage spare ribs strip steak burgdoggen pancetta&lt;/p&gt;
    &lt;button class="btn btn-success btn-lg"&gt;Hi there!&lt;/button&gt;
  &lt;/div&gt;</code></pre>
  </div>
  </div>
