Good evening

In my page, I added a block. for example a block with pricing. By default, there is no background selected in the block. I want to change the background with an image, which is uploaded already. Fact is, when I go to the settings of the block, and I change the background of the block from "nothing" to a "selected image", this image is used as a background for the whole page.

Is it possible to change only the background of a "block" or not?
