vBulletin Question

Ok, I'm fixing up someones skin, its had alot of errors mainly because of the way the designer brought the css into the forum, via a external css style sheet removing most table and so on codes from the layout. My question is, is it possible to make the breadcrumbs stay the same font style throughout the forums, like now when u click on forum it makes the font style it was on the forum index change into something else and makes the forum area your in the font style it was originally on the index, ive seen most forums are like this. so my question really is 1. can it be changed? 2. if so how?
