WordPress Theme Destruction

In my attempts to fix my theme, it seems that I have destroyed it.  As you can see the font sizes are way off, and really I am unsure why… seeing that I didn’t change any of the CSS on the page.  Guess this is more motivation to get the new theme out, though I am really not sure its ready for production yet since I just started creating it about 3 days ago, and really only spent about 15 minutes working on it.
