Here's the setup: I want my story to have large background images that cover the browser window (as seen here
So what I'm thinking to do is just create a "backgroundmask" div immediately inside body with absolute positioning and width and height set to 100%. That should cover the full screen as desired, and I can mess around and change that div's background-image, and fade it in and out at will.
Assuming that's the best way to approach this problem (which it may not be), my question is: how should I go about adding this new div to the dom?
I see SugarCube 2's HTML structure here
Thanks in advance for any help!
