Very simply, I'm trying to fade in the background-image of a div; I've seen this done with two divs and effectively revealing (i.e.: faux fading in) the background-image by fading out the background-color of a div covering the background-image. This will not solve my problem.
The above mentioned solution works if the "mask" is the same solid color as the body background-color. In my case, the body's background is a textured image, so this will not work. I could set the "mask" div to have the same background-image as the body, but having a z-indexed div seems like overkill.
tl;dr I have a div somewhere in the body--how do I fade in its background-image? Thanks!
