The beginning of a website

I've started building a website to demonstrate some of the things I can do with webpages. It isn't much right now, the colors need work, and I'm certain that it will look weird on a few web browsers, but it should grow over time (especially the section devoted to IE weirdness).

The page doesn't render correctly when viewed with Mozilla-based browsers, but the headers for link groups are still clickable.
