I have some span tag with let's say #span id that has the property background: url(some image) -22px top no-repeat, which displays some image as a background.
If it has the property background: url(some image) -22px top no-repeat, another image is displayed. The problem is that if I specify ('#span').attr('background-position','0px top') nothing happens, the other image is not displayed. Could someone explain why?
