Ah, I see. Yeah, in that case JavaScript won't work for you since you can't edit MediaWiki: pages to deploy the JavaScript.

It's not impossible without JavaScript. In can be done with HTML/CSS on an ordinary wiki page. But no matter which way you do it, it's tricky to do ... and there will be some quirks to overcome. (One obvious point being that the example I've given won't work in the Monobook skin, only Oasis.)

Since this is a lot to explain in one post, I created a page at w:c:mathmagician:Using element inspector to study HTML and CSS that explains a different approach to this problem.

Here's a copy of the basic example shown on that page. Notice that the color should be a different color here on your wiki than over on that page on my test wiki.

This background matches the color of the Wiki Navigation.
