Is it possible to not render a background (Skybox, Color, etc.) in WebGL?

According to a post long ago this wasn’t possible with the Unity Web Player plugin.

This functionality would be useful if the background of the webpage had a pattern or image. Essentially, the webpage background becomes the game’s skybox. Is this possible, and if so, how so?

You can’t create a transparent player out of the box if that is what you mean.

But since the WebGL export is just a giant JS blob running in your browser you might be able to hack this somehow but it sounds very much not trivial.
