    <h1>Zooming</h1>
    <p>
      This demo demonstrates zooming. It relies on the <a href="http://plugins.jquery.com/project/mousewheel">mousewheel plugin</a> to detect mousewheel events. Use the mousewheel in the middle of the screen to zoom in and out. Notice how the boxes are resized and their relative positions are preserved.<br />
      Use <tt>right click > view source</tt> to see the underlying Javascript code.
