in the Unreal Engine forums web by default the site shows up in dark mode , black background with white text. I prefer using it with a white background instead.
I tried using a Chrome extension that inverts the colors, but it’s not perfect, and it’s kind of abandoned now. I switched to Firefox to try it there but has color issues. Is there an actual setting on the forum site itself to switch it to light mode?
If the forum doesn’t offer a light mode (I haven’t seen it), I’d say don’t bother trying to make one with CSS. They managed to add in hundreds of color variables in the CSS files, takes too much time.
