This code works in Safari, IE7, and IE8, but not in FF 3.5.7. The code changes the background of the little background icon when you hover over a div.
jQuery(function( $ ){
 $('.oneThird').hover(function(){
  $(this).find('span.icon').css( {'background-position-y': '-60px'} );
 }, function(){
  $(this).find('span.icon').css( {'background-position-y': '0px'} );
 });
}); 
Can someone help? Thanks so much.
