Getting your scoreboard into streaming software

[Velyks]

HI,

Is browser source + chroma key the only viable solution we have to getting the scoreboards into streaming software?
OBS's chroma key isn't that great and leaves either a blurred edge or a bit of the key colour showing, is there any way in CSS or otherwise to tell the background to be transparent?

How have other people gotten their scoreboards into their software?

Why use a chroma key? Chomium handles transparency perfectly fine.

I couldn't get opacity to work, am I missing something? Sorry this is more of a CSS question and less of an 8wr.io problem.

OBS's chromium browser is already set to ignore backgrounds.

If you look at my scoreboards:

You'll see that the black bars on my overlays fade out into transparency.
