Resolved Question: What's wrong with this DIV code?

I am trying to apply a DIV layout to my IMVU page, but whenever I try to paste it in the HTML/CSS section it just makes the whole page blank.

The original code is from the side in the credit at the beginning, but I edited colours, fonts, etc. I was just wondering what seems to be wrong with it. Thankyou if you can help (:
