External Navbar (CSS or XML?)

Forgive me I’m a total newb at web design but I was wondering if it was at all posible to build an external navbar using something like CSS or XML.

The reason I ask is because I have a site with quite a few pages, and it’s likely I’ll be needing to update the navbar from time to time. I’d rather not have to change every single page. I thought perhaps this could be accomplished via something like XML (I’ve seen similar things done in Flash, but I’ve scoured the internet and can’t find anything for HTML.)

It really is just simple text links such as:

Home| About| Stuff | More Stuff etc.

It’s probably something really simple that even preschool children can do, hence the lack of tutorials around, but like I said I really am quite inept at this sort of thing.

It’d be nice if I could style it with CSS too :slight_smile:

Any help appreciated :thumb:
