Hello fellow Defolders, I’ve got a quick question for you all.

_Is it possible to change the color of the background on HTML games?_

Below is an example of what I’m talking about, my game is designed with a vertical screen orientation, and when played on desktop I get these thick borders. I get that they must be there, but is there any way I can make them black? They are rough on the peepers.

Have you tried building with dark theme selected?
