I know changing the UI style in offline mode is a different process from changing it in online mode...
But I don't entirely grasp the process differences individually.
If I wanted to create a new UI style (not simply changing colors around, but actually using new images and button skins and such) what file would I need to change/include?
Would that automatically be included when I uploaded the game?
Would I need to change any significant code, or will CSS be enough?
