I was researching for my company project how to repeat in a background a section of a image (a sprite) without repeating all the image.
I found the css image() notation in the standard. But it doesn't work on firefox 39 and I don't find any information of this notation on the Internet.
The only document that I found is in the MDN and was deleted in 2014. https://developer.mozilla.org/en-US/docs/Web/CSS/image%28%29
Anyone has information of this notation? Implementors, state of standard, etc.
