I need to convert my CSS to HTML for a specific application; how can you do it correctly? And use inheritance.

I have a specific situation that requires me to reduce my CSS stylesheet to XHTML. Rather than an admonishment about "why" I shouldn't, I would like advice about how to do this properly - is there a tool out there that will do this? For example, it would need to consider other directives in the stylesheet that relate to each item, etc., then combine them properly into XHTML/HTML4.
