Please add support for rendering chat with custom css. Plenty of streamers use custom css chat overlays that are custom made or from services such as NerdOrDie, StreamElements, or StreamLabs. Having a way to render chat from clips and VODs in a style similar to the overlays already being used would be great for adding chat to edits for shortform vertical content like Reels, Shorts, or TikToks.

The chat renderer is not based on HTML or any graphics frameworks that support CSS - all of the styling is programmed in by hand. Supporting CSS would be insanely difficult unless the renderer is rewritten in HTML, which I don't really want to do.

Completely fair and understandable.
