Is this possible currently?
Currently you can only use web containers as the body's background or as a component.
Is there a specific use case for why you would want to use it as background instead of a component?
I wanted to give each section an alternating subtle gradient color background, but it's not critical at all, I was curious if I could use the web component for that
Got it. Yes there is no way to do this at the moment. I'll consider it in the future if enough people request this.
