Depends! My profile uses this code + this snippet + this snippet, the latter of which I also repurposed on all my OCs for art permissions, using a this snippet as a base. My commissions page was originally this code,  but I frankenstein'd it so much that there was a problem when viewing  it on mobile, so I took what I liked about the layout and recoded it  from scratch myself. The cover-all bg snippet I used I don't think  exists any longer so I've been grabbing it from when I used it on older  codes, but the fake CSS codes here would probably be comparable. That same cover-all bg code I've been using I just re-lifted from here, whose main code is by cosmical. This one I've used a few times, too. And this one a couple times. This one once, and this one once.

This is a pretty common code on my profile, I did this years ago and it's kind of wonky due to its age, but you can still get it here, as Wide and Long. My folder info code is also there. 

This, this, and this are all my layouts and are all personal. This one is released, but only to the Ringox CS community.
