Is it possible for someone to please give me a list of all the available fonts that can be used in Wikia.css? I've been trying to change a username's font and most of the fonts I've tried haven't worked. Thank you.
You can find lists of web-safe fonts multiple places around the web; here is one of them. However, you should note that even web-safe fonts are not guaranteed. Information for a font has to come from somewhere. If neither your wiki nor FANDOM's platform are providing that information, then you are relying on the viewer to have the font installed on their computer. Web-safe fonts are fonts that are "common enough" that most computers will have a local copy.
