it seems like they took a layout they liked from that community and tweaked it. so the base html, etc. is from coding but the rest is their own stuff.
some suggestions: - find a layout you like on there and mess with it - message the person or comment, i have seen many of these individuals share the code with no problem. - right click the layout and view source. i wouldn't suggest just stealing the code but you can use it as a guide.
sometimes if i forget what something does, i refer to this: http://everything-lj.livejournal.com/4632200.html i don't use that post for the express purpose of making a layout like that, but it gives me a general idea of what the codes are supposed to do.
