I really liked the fast rollovers technique I discovered here ->

Now I'd like to make a navigation kida like this - >http://wellstyled.com/files/css-nopr.../example2.html , which is no problem, but I want my menu to display the 'current' page as well - when you're on, for instance, the first page (like in the example), I'd like the background to be darker blue (rollover state).... So, no rollover for that perticular menu item.

Can this be done with CSS or do I need a bit of PHP as well? Any exaples would be welcome.
