In the nicest way possible - your CSS will have been for the old layout, which now has changed. This means your CSS is incompatible and needs updating if you wish to keep using it. If the base layout changes then these kind of things will happen. This is actually why Niet tries to avoid layout changes like these but... Well, it was necessary. You'll need new CSS, timid. Sorry!
