A jQuery code snippet isn't working upon page load. It should replace 'frame--layout-vertical' with 'frame--layout-horizontal' and padding-bottom: 56.25% with padding-bottom: 100% when the screen width is greater than 641. By default, its frame--layout-vertical and padding-bottom: 56.25% (given the html below). 

Its working perfectly when I resize the screen a bit after page-load. 'load' isn't working. 

Here is the jQuery:

```
<script type="text/javascript">

        $(window).on('load, resize', function frame() {
            var viewportWidth = $(window).width();
            if (viewportWidth < 641) {
                $(".frame").removeClass("frame--layout-horizontal").addClass("frame--layout-vertical");
                $(".image").css({'padding-bottom' : ''});
                $(".image").css({'padding-bottom' : '56.25%'});
            } else {
                $(".frame").removeClass("frame--layout-vertical").addClass("frame--layout-horizontal");
                $(".image").css({'padding-bottom' : ''});
                $(".image").css({'padding-bottom': '100%'}); 
            }
        });

</script>

EDIT: When I am using a auto load pagination. The my jQuery code isn't working since the browser isn't loaded. Can you please give me a suggestion? How can I call jQuery code with auto pagination? 

Here is the autoloading snippet.

```
<script language="Javascript" type="text/javascript">

    $(function () {

        $('div.sponsor-articles.sponsor-section').infinitescroll({
            debug: true,
            navSelector: 'div.appPaginatorContainer', // selector for the paged navigation
            nextSelector: 'div.appPaginatorContainer span.next a', // selector for the NEXT link (to page 2)
            itemSelector: 'div.sponsor-articles div.frame', // selector for all items you'll retrieve
            bufferPx: 40,
            debug:true,
                    columnWidth: function (containerWidth) {
                        return containerWidth / 5;
                    },
            loading: {
                finishedMsg: 'No more pages to load.',
                img: 'http://i.imgur.com/6RMhx.gif',
                msgText: 'Loading more posts'
            }

        });

    });

</script> 

```
