title: Can't add background image into Jumbotron for Rails App
body: <p>I'm working on a rails app built with devise and I can't seem to add a background image to my jumbotron on the home page.</p>
  
  <p>The image file is app/assets/images/background.jpg.</p>
  
  <p>Here is the html for the home page located in app/views/home/index.html.erb</p>
  
  <pre><code>    &lt;div class="jumbotron"&gt;
      &lt;h1&gt;redacted&lt;/h1&gt;
      &lt;p class="lead"&gt;redacted&lt;/p&gt;
      &lt;p&gt;
          &lt;a class="btn btn-lg btn-success" href="users/sign_up" role="button"&gt;Sign up today&lt;/a&gt;      &lt;/p&gt;&lt;/div&gt;
  </code></pre>
  
  <p>In app/assets/stylesheets/home.css I've added the following code:</p>
  
  <pre><code> .jumbotron {
   background: url('../images/background.jpg');
   }
  </code></pre>
  
  <p>Any help as to why the background image won't render would be much appreciated!</p>
