I'd like to do some minor changes in the way WIki text is shown. For instance, if I use <code> tags (or == markup), I'd like to give these fragments a light background color. Is there an easy way to do this (using some stylesheet customization, perhaps)?
I think the easiest way to do this is to add style definitions for <code> and <tt> tags in your stylesheet. That way, it will work for all occurrences; not just within the wiki.
