title: Can you make toggleClass animation without jQuery UI?
body: <p>Can I make this: <a href="http://jqueryui.com/demos/switchClass/default.html" rel="nofollow">http://jqueryui.com/demos/switchClass/default.html</a> without jQuery UI?</p>
  
  <p>Basically I have a simple site which the body has a class named: <code>'.bgone'</code>.</p>
  
  <p><code>.bgone</code> has <strong>background color: #ccc</strong> and I want to toggle the <code>.bgtwo</code> of which <strong>backgroundcolor is #999</strong> with the <em>fade effect</em>.</p>
  
  <p>Is it possible with only jQuery?</p>
  
  <p>Thanks</p>
