Footer doesn't move down when the left side menu is large

I had redone the CSS to allow the footer to stay at the bottom of our product page but it seems that if the left-hand side contains more information than the body does, the footer cuts the left off, instead of moving down to allow the left-menu to 开发者_如何学JAVAbe completely shown. I've tried a number of different solutions to this and I think it may have something to do with the page being dynamically generated (ASP Classic) so I don't have the option of specifying a height. Any insight into what I should either do, or any help would be appreciated.

Thanks.

The problem you have is because the left menu is position: relative;, but there are other problems that prevent a simple solution to your page.

My advice is to check other 3 column CSS layouts, like The Perfect 3 Column Liquid Layout
