I have a recurring bug on webflow I didn't have time to talk to you about. I've reproduced this bug several times so it's for sure an issue.
When I set up my background with transparency, 1 time out of 3 Webflow doesn't take it into account. I have to remove the style, publish, and then set it up again, and re-publish again to see it live.
Here's the screenshots:
you can see the background is present
no background !
