So setting a font on a webpage is as easy as saying font-family:monospace;
(in the right place of course). Wikis also allow you to edit site-wide CSS (which that code is) (although Wikia does have some constraints).
"recently" I edited the wiki to make headings more obvious by adding the following line to MediaWiki:Common.css:
.mw-headline { font-family: Impact, Charcoal, sans-serif; }
The way CSS fonts work is by trying to load fonts onto the webpage from your computer starting from the left (so if your computer doesn't have an "Impact" font, it'll try "Charcoal" next) (this is important since not everyone has the same fonts).
TL;DR: Anyways, my point / question is this: What fonts do you think best represent headings?
I originally just picked the first recommended "bold" pair of fonts I could find. But I'm not sure if they are the most legible of options. So since changing them isn't hard, I'm curious what fonts people might suggest. Google fonts (look it up, I'm not explaining) are fine if it just 1 and it's the best thing ever - but good, relatively common fonts are "preferred".
