Fairly simple CSS question *I think*

alright well, I have what I hope to be my first all CSS site starting up and what im having trouble figuring out is getting the site to fit the screen.

theres the files, as you can see my site goes to like half the screen. Id like to get the entire thing to be 100% height. Yet, I cant seem to get that to work to fit the whole page. Am I missing something?

Thanks in advance.
