Thanks for the response, crayoncrisis. And unless I am misreading the information in the links you provided, I could make a specific template for a category, but that would be used for the category page.
What I want to do is assign a style sheet for a single post (that applies to all posts) in a category.
Alternatively, Ideally I would like the ability to do it to a for a single post with a specific tag. It makes no nevermind whether I use tags or categories, I just want to assign a stylesheet to a single item page that is either tagged or categorized to a corresponding item. Did that make sense?
Did I misread something?
