Remove Background

Hi

How can I remove the background bezel? I can change the color to white so it doesn’t appear as visible, but that causes issues with margins. I just want to remove it, so only the dark blue tracks are there – with no black background.

I have also used display:none, but that just removes the whole thing. How can I remove the background specifically?

Right now it looks like this https://i.imgur.com/8YSCgRe.png

I’d like it to just look like this https://i.imgur.com/aR8ruFT.png
