This is probably really simple, but for the life of me, I cannot figure out why my custom banners look fine in one theme, but are transparent in the other theme. For the record, there are three custom banners. This is one, and how it is supposed to look: This is the other theme, where the banner turns transparent. I wanted the banners to look the same across all themes. Granted, I am fairly new to coding, css, and everything of the sort, so any assistance is very much appreciated.
