Gallery captions appear in a div with the following class: .lightbox-caption

So you can create new rules in your wiki's CSS to change their appearance. For example: .wikia-gallery-caption .lightbox-caption { background-color: #0E0E0E; }

If you only want certain galleries' captions changed, you'll need something more specific. First wrap your gallery in a div like so: (GALLERY CODE) Then your CSS rule would look more like this: .custom-gallery .lightbox-caption { background-color: #0E0E0E; }

You can use a different class name than "custom-gallery", but make sure to use the same on the div and in the CSS rule.
