I'm trying to figure out how to make it so that people can change the background of a template, but I'm used to using source editor code, not this newfangled Infobox Builder code. I want to keep the template the way it looks, but I also want to be able to change the background and header colors so that users can costumize it to fit the character. Can someone explain how this would work?
