Forgive me if this has been posted previously but I didn not find what I was looking for when searching.

I would like to make all top level categories bold in the categories sidebox while leaving the subcategories the way they appear now. Can someone point me to the correct css file to edit to accomplish this? If it's easier to hack in a bold html tag I'll do it that way, but I wasn't able to find the file I need to edit to accomplish this.

Also, does anyone know of a good and easy way to force multi-line subcategories to autoindent the second line to be even or perhaps indent more than the second line?
