Messing With Firefox’s View Source CSS File

Firefox has a number of core CSS files that it uses to render web pages. Most of them are filled with sensible default values for all those pages out there which don’t provide their own styling. For example, Firefox has its own CSS file just for forms called forms.css which gives form elements their special Firefox form look.

I highly recommended NOT messing with most of these core CSS files. We are web designers, after all, and we really need to be viewing web pages in our browser the same way that everyone else is. If we go around messing with that, we have no common ground. There is, however, one that you can mess with that’s not going to do you any harm can be good fun. That is Firefox’s viewsource.css.
