I'm pretty new at this stuff, but I did get a website up and working. I made some changes today and for the life of me I can't figure out why it breaks in Firefox! I've tested it in safari, opera, and chrome and it looks fine, but it breaks something awful in firefox! Any help would be greatly appreciated.
