expression(this.offsetparent.scrolltop) not working in ie11





Now, the issue is this code works just fine in chrome, firefox and opera but when I open this page in Microsoft Edge or in IE 11 all grid items are overlapping each other at first cell.Why is it not working? Works great in Safari, Firefox, and Chrome, but fails to work in IE, only when I manually scroll I get the result that I wanted. Im using this version,
