How do you create a stable image with a scrolling box above it using css?

I'm looking to create a css-based website similar to http//www.csszengarden.com/?cssfile=213/213.css but can't figure out how to keep the bottom stable while the top part scrolls. Thanks!<br />

<style type="text/css">
#footer{
width 100%;
left 0;
position fixed;
bottom 0;
}</style><div id="footer">Footer</div>
