Does anyone have a pre-made stylesheet for wiki pages?

Although I wouldn’t mind making a custom style sheet, it would be quicker to find a style sheet that’s already been made. I’m currently trying to make a wiki page for something and I don’t want to use websites to make one for me and I’d prefer to program my own. Is there a publicly downloadable stylesheet that resembles the stylesheet appvalley used by Wikipedia or other related cites? tutuapp
