>Is there any way to use style sheets and still score well with the search engines?
Sure - use the LINKED kind of style sheet instead of loading all that
style stuff in your headers or around the paragaphs in the text.
Brainwipe did a good job of explaining them.
The advantage is that you only have to change ONE file in order to
change multiple pages (easier for you), and the visitor's browser only has to download
the information once (faster for you). And I'm always in favor of faster and easier.
