Board Thread:Support Requests - Designing Your Wikia/@comment-27515292-20160103203231

So I recently posted some questions about Templates and Fonts. I understand the Template Creations, but I am still a bit confused on the steps of how to change your Wikia's font. Can someone help?

"CSS" was mentioned in the comments. What does "CSS" mean?
