I want to change the back ground or add a border down the side

Tonight I am going to focus on figuring out how to add a border instead of keeping the square elements at the top of my page. I also want to change the back ground instead of keeping it all black. So I am not going to focus on posting, because I think I have it figured out, at least the basics of it anyhow. Cheers for tonight. Maybe I can change things around by tomorrow.
