jQuery resize function doesn’t work on page load

This solution is now deprecated since jQuery 3.0: https://api.jquery.com/bind/#bind-eventType-eventData-handler

You’ll want to use:

$(document).ready(function() { /* your code */ });

To make something happen onload. If you want something to work onload and onresize, you should do:

onResize = function() { /* your code */ }

$(document).ready(onResize);

$(window).bind('resize', onResize);
