That's really nice of you to say! :) The wiki's founder Jetnoire is the one who did all the design here, she's great

A lot of the site design is done with CSS in addition to wikitext, which I agree can be hard learning on your own lol speaking from experience. I'm not nearly as proficient as Noire with CSS & can't dedicate extensive time for coding help with your wiki. but if you have any specific questions or just want another eye to look over any of your code, feel free to drop a message on my wall.

Fandom has a lot of help pages for learning these things so I always use those as a starting point. for me the subreddit (r/wikia) has been helpful for more specific questions, so I'm pretty active there. Fandom has an official discord server too where people often ask for help with stuff.
