Wrong css in fullscreen-tutorial

If you test http://www.kirupa.com/developer/mx2004/fullscreen.htm it will not work.
I use:

<style type="text/css">
   <!--
   html, body {
      height: 100%;
      width: 100%;
      margin: 0px;
      padding: 0px;
   }
   -->
   </style>

(that was maybe to much but it works)
