Your CSS information is not properly located, so it actually appears as text, rather than affecting the design of the page!
You have a header, your forum name, and two paragraphs!
However, you don’t seem to have the footer, a background image (I think a background color also works to show the relevant skills and is easier to work around linking files (@fraud?)), and the margins (due to an error with the code).
Hopefully that helped! Feel free to tag me if you have any questions, because I’m online often and can probably help.
