div 100% height?

Hey!
I want to make divs as high as the page (depends on what page you're on, so it can't be fixed).
Here is how the divs are aligned:

I googled but couldn't find the right answers :( hope someone here can help!

have a nice day :)

The downside to div layouts is that you can't really do the 100% height routine with them. People have devised ways around it, but probably the simplest and most common method is something called "faux columns."

Search the forum and/or Google and you will find samples and tutorials to explain the idea.
