was just wondering if possible to move background position with click of a button (toggle). so created example http://jsfiddle.net/VpULJ/2/
basically i want on click of the "click" button the content wrapper show up. what i want is to shift the background position right the bottom of the #wrapper div.
in next click wrapper gets hidden and then i want to shift the background up where it was (possibly with animate). been trying to figure out for long. anyone pointing to the right direction would be great help.

Thanks
