Similar to the infoboxes on the Dragon Age wiki (Example), I want to add a background to my infobox templates, but I'm unsure how. I tried to look into their coding and templates to see if I could get an idea, but I haven't found any helpful (or comprehensible, at least for an editing novice like myself) information.

I would like some assistance on figuring out what I need to do or what codes I need if I want to put background images on my infoboxes. I would sincerely appreciate any help I can get.
