-

i have span tag let's #span id has property background: url(some image) -22px top no-repeat, wich displays image background. if has property background: url(some image) -22px top no-repeat, image displayed. problem if specify ('#span').attr('background-position','0px top') nothing happens, other image not displayed. explain why ?

use .css()

$('#span').css('background-position','0px top');

.css() -> value of style properties first element in set of matched elements.
