How do I change blog text size on front page myspace profile?

I've seen some people with large text in the box that shows recent blog entries on the front page myspace profile (not in the blog itself). I know how to change the text size, and I can change everything else on the page, but I can't figure out where to put the HTML to effect the box showing the blog entries! It stays the normal default size. Has anyone done this?
