body: <p>I have a class </p>
  
  <p><code>.tab{filter: progid:DXImageTransform.Microsoft.gradient(startColorstr='#f5ffff', endColorstr='#e8f2f8');}</code></p>
  
  <p>and when one of the tabs is selected I want to remove the filter:</p>
  
  <pre><code>.tab.selectedtab{/*what do I put here to remove the filter?*/}
  </code></pre>
