What is going on?

so I have no idea what is going on, my blog colors are all messed up! Don't know where the purple and bright blue borders are coming from. After an hour of studying the underlying code I can not find the problem! So frustrating, urgh! I did get a bizarre comment on one of my posts from some unknown person recently. Maybe they are messing with my website too? Hope to get it fixed soon. Sorry about the crazy color combinations, I really can coordinate. This was not intentional : )
