Over at The School for Good and Evil Wiki, I imported a Google font named "Cardo", and I followed these steps and partially changed the font of the wiki.
The wiki header, the page names, the history, everything except for the page body, is in the Cardo font. The rest of the page (the page body) is in the Century Gothic font, if I'm not mistaken.
Is there something wrong I did with the Wikia CSS and/or the Common CSS? Why did the font of, if not the entire, but most of the wiki not become Cardo?
