title: Changing the background color on focused select box option does not work
body: <p>This is specifically with the selectBoxIt jQuery plug-in, using the jQueryUI theme.</p>
  
  <p>I have this set up for the hover action:</p>
  
  <pre><code>/* Individual Option Hover Action */
  .selectboxit-option .selectboxit-option-anchor:hover {
    color: #ffffff;
    background-color: #ff0000;
    text-decoration: none;
  }
  </code></pre>
  
  <p>That works fine. When I hover my mouse over the options, I get a red background with white text.</p>
  
  <p>However, when I do this...</p>
  
  <pre><code>.selectboxit-option:focus .selectboxit-option-anchor:focus  {
    color: #ffffff;
    background-color: #ff0000;
    text-decoration: none;
  }
  </code></pre>
  
  <p>...nothing changes.</p>
  
  <p>I see that all the demos on selectBoxIt's main web page DO have changing background colors with keyboard focus...so what am I missing?</p>
