title: Changing selected background color of a select element
body: <p>I have this:</p>
  
  <pre><code>&lt;div id="root"&gt;
      &lt;select onchange="go()"&gt;
          &lt;option value="1" selected&gt;A
          &lt;/option&gt;&lt;option value="2"&gt;B
          &lt;/option&gt;&lt;option value="3"&gt;C
          &lt;/option&gt;&lt;option value="4"&gt;D
          &lt;/option&gt;&lt;option value="5"&gt;E
          &lt;/option&gt;
      &lt;/select&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>How can I change the standard selected background blue color to red???</p>
  
  <p>I can not find any solution, not even the ones in other questions in the stackoverflow...</p>
