How to syle permalink page in 1.5 nightly?

Ok, I got my more tag working, comments working, and everything is looking good except if you click on “archives” at the top, then click on a thumbnail, it goes to the permalink of that post, but it is styled like kubrick. I am wondering where do I get the permalink page to recognize my stylesheet?
