Ok, I have finally got to working on my portfolio: http://www.tysonhardy.com/

But when I had no doctype and had my style sheet placed inside index, it worked perfectly. Then once I added a doctype and linked to the CSS, it stopped working. Then I took out the doctype, and still the same problem. I think I'm linking to the CSS right, so I have no clue what's wrong. Please help.

<link rel="StyleSheet" href="stylesheet.css" type="text/css">
