XF 1.2 How to style Staff Member banner?


Well-known member
I know where and how to change the color of User Banners for various User Groups, but where can I style the Staff Member banner, please?

What exactly I need to enter to the field "Other, using custom CSS class name" in User Banner Styling? I guess here I can make more colored banners, but not sure how I will achieve this? Can I only change the background of banner and font color or are there other things that can be changed too to?
