Help, big css error

[n3n]

Hi, last night i made some changes to my css. I went out after that, and now i cant remember what ive changed.
An album page ended up to look like this... Could someone give me a hint on which css classes could have done this.

Been looking for hours, but cant find it.

post a link to your site where we can take a look for ourselves, a screenshot doesn't help much.
