This Scrippy is the same as example one, except I've added an additional background to each container so that the opening and closing follow one another.   

This is accomplished by setting the horizontal and vertical spacing for each background at 3 times the graphic width, which in this case is 450 pixels.   (150x3)

The second background added to each container must have the vertical and horizontal spacing set at 2 times the graphic width so that they show up after the first set has disappeared.   In this case that would be 300 pixels.  Depending on which container you're working with, that number will be a minus 300 or a plus 300.   I've numbered the graphics to help you see the settings for each background.
