Common Templates Not Common?

[Toni3055]

Hello!

New to vB4 and have hit the decorating ground running. Not doing too shabby except for a few minor things, one being a "common" issue.

I've added two extra backgrounds to my forum, one on the sides and an actual footer. To add the side background, I added a new class called "side_wrapper" to the common header template and closed it in the common footer template, where I added and closed the actual footer background, as well. The styling for both is in additional.css. Works flawlessly on the forum itself. And looks lovely, if I do say so myself.

The problem is, when I go to any page aside from the forum, like editing my user profile, for example, the sides and footer disappear. I surmise I must add their classes to additional templates, but I have no idea to which ones. Any help would be greatly appreciated. Thanks a bunch!
