How do you find the background-size percentage of an image?

What are you comparing???

I believe that asasass is trying to work out the percentage of a single image that’s contained in an image sprite compared to the whole sprite that contains multiple images.

I have tried to answer that question in this thread.

Preventing an image sprite from going into the other image when zoomed

That’s fine but that doesn’t mean everyone else will. You can’t use cover on a sprite because that refers to the whole image and not just the little piece you want. I think you are talking about how to make the one sprite as a percentage of the whole sprite? If we take this image for example.
