How do I replace background image in BS5 block?

I’ve simply dragged a Bootstrap 5 block onto a new page, but cannot figure out how to replace the background image of the circled div.


The image is defined through a CSS rule.

Great, thanks for that. Now how do I replace the image since bootstrap.css is locked? Is there an instructional video available that explains all this specifically?

@sebrame this image is selected in the Design panel. You can disable showing the image there and then add a normal IMG element to the page.

Here is more about using the Design panel (it generates a custom Bootstrap theme for you):
