element()
The CSS Image Values and Replaced Content Module Level 4 introduces the element() function. This function was previously defined in Level 3 and so Firefox already has support for it, since its version 4 (May 2011!). To put it simply, this function renders any part of a website as a live image. A. Live. Image! As you see a DOM element rendered right in the browser, you’ll get an image of it. Every changes to that element will be immediately seen in real-time in the image, even text selection.
