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.

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.
