I found this great tutorial at titled "CSS 100% Height DIV's tutorial" at
http://www.webmasterworld.com/forum83/200.htm, which seemed to solve my problem. I'm creating a new site with a three column design, a header, and a footer. When I copied and pasted the code into my page, it worked great in IE6, IE7 and Firefox.
So I then entered code for a header and a footer, and it again worked great in all three browsers. But when I tested it out by entering a bunch of <br />, the footer didn't stay at the bottom of the page.
If anyone can look at the code below, and let me know what I'm doing wrong, it would be greatly appreciated. Thanks for any help.
Code:
