title: jQuery: loading css on demand + callback if done
body: <p>I want to load CSS files on demand (by eg. running an XML HTTP request which returns the CSS files to be loaded) for example <strong>style1.css</strong>, <strong>style2.css</strong> ..</p>
  
  <p>So is there a way in jQuery (or a plugin) to this?</p>
  
  <ul>
  <li>bulk-loading several files + adding all those CSS-files into the dom</li>
  <li>when finished loading: firing a callback (like alerting "all stylesheets are finished loaded!");</li>
  </ul>
  
  <p>the idea is: loading <code>html</code> via <code>xmlhttp</code>, loading +adding <strong>required</strong> css-files,
  then - after anything is finished, display that <code>html</code>.</p>
  
  <p>any idea?</p>
  
  <p>Thanx!</p>
