title: Change color of input autocomplete box
body: <p>When you click inside the username input box a list of suggestions is displayed in a drop down. How do I change the background color of that dropdown? </p>
  
  <pre><code>&lt;div class="form-group"&gt;
           &lt;input class="form-control" required&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>PS: I have seen a couple of answers but none answers this particular question</p>
