Applemasterexpert has a lot of CSS there. It might be helpful if you just posted the relevant parts in your reply.

Regardless, changing the page title in this manner is technically a customization policy violation.

Even if it weren't, I would advise against it. "Rainbow text" is frequently requested because it "looks nice". True, at a glance. However, if someone is doing a lot of reading on your wiki, it quickly becomes an eye sore. On top of that, it relies on an unofficial CSS property value. Since the value is unofficial, implementations are browser-dependent; assuming it is implemented at all.

If you do use this, be sure the fallback color looks good. Users sometimes don't do this because they assume everyone will see the rainbow text. That assumption isn't true. As such, if the fallback color doesn't work well, then users who don't see the rainbow text will be seeing something that doesn't look nice at all.
