EDIT: Background Problem (another Prob)

Edit: Connorhd sorted out my original problem (see below) but how do I repeat the process for changing the background colour for the links at the bottom of the page? Again it is just the Page Numbers, Back to Index link, and Post New Topic link. Anyone know the code? Thanks

Yep it's me with yet another problem

My new style has been edited to suit my site design but when inside a forum you can't see the 'page number' links or the link back to 'index' - well you can see them but they're hard to read. Is there any way I can change just that line to have a white background to help make the links stand out more?

Ideally this is what I am wanting the finished result to look like.

Any ideas on how to go about this?
