I have a 1048 x 1200 image that I would like to use as background image wherein the full width of the image is visible and scrolling down the page will move to the bottom of the background image but then if the content is longer than image the image sticks when bottom is reached while rest of content keeps scrolling.
-or-
to have the background scroll slower than the content (parallax) so that the image and the content both end at the same point.
Anyone know how to do one or the other of these effects?
