You should write a short guide on formatting your deck's background and textboxes like you did, because as far as I can find no such guide exists on the site. :)

I honestly just scrounged the code from around Tappedout and figured out through trial and error how to make it work. I'm self-taught, and really don't know programming very well.

I'd be hesitant to make a guide simply because I'm no expert, and I'd be appropriating the work of others and I don't really want to take credit for stuff I didn't originally create. Additionally, the customization doesn't always load properly, and I don't know why, so I'm ill-prepared to field the inevitable pleas for help fixing it when something goes wrong for someone else.

I will say though, if you want to have something similar, there are posts in the forums with the code and everything you need to make it all work.
