You can do that by adding a suffix to your selector of body.mw-special-Forum, like: Which adds an underline to the policy button text when hovering above it.

To add to the forum a background, you can do something like this:

Applying a background on all pages in a category is a bit more complicated. There are 3 ways to do it:

The first one is to apply CSS on each individual page in this category. Its main problem is that it requires constant updating:

The second method is to create a MediaWiki page that contains the following HTML code and embed it with verbatim. On this example the category page is used like a template that you can add to pages. Suppose you choose a page name MediaWiki:CategoryBG Harry Potter:  body.page-Harry_Potter, body.page-Hogwarts, body.page-Dumbledore { background: white url('SOMEURL') top center no-repeat !important; } Then add to your category- say- Category:Harry Potter, the following text: This category includes articles about subjects from the Harry Potter world. CategoryBG Harry Potter And to embed the category and the BG in a page, add to the end of an article:

The final way to achive a background for pages in categories is via your MediaWiki:Wikia.js. JavaScript doesn't affect the page immedietly, so at first the background will be the default background, and will be changed withing a second or so. Therefore it's not very recommended.

Anyway, to achive this, use the following JS code:

Anyway note that if a page contain several categories that you applied background on, only the last declared styling will be the dominant, and will override the previous backgrounds.
