Because of IE9+ browser, jquery cannot get the initial value of backgroudPostionY 60px, add a sentence in mouseenter to view it

console.log($(this).css('backgroundPositionY'));

In IE8, the actual value is 60px, while in IE9+, it is undefined, and naturally it starts from 0 and goes to the top - -
