Here's how to make your site not load CSS and/or JS in IE older than 11:

<html>
    <head>
        <meta charset="utf-8">
        <meta http-equiv="X-UA-Compatible" content="IE=8,9,11">
        <title>Page title</title>
        <!--[if !IE]>-->

	var TrafficModule = (function (module) {

	var newPercentIsValid = function (newPercent) {
	var intPercent = parseInt(newPercent);

	return (intPercent <= 100) && (intPercent % 20 === 0);
	};

	module.updateTraffic = function (newPercent) {

	window._eventLog = (function(longTime, important) {
	var eventLog = [];
	eventLog.getLongEvents = function(time) {
	time = time === undefined ? longTime : time;
	return this.filter(function(el) {
	return el.time > time;
	})
	}

	// Should we filter mousemove?

	(function() {
	var method;
	var noop = function noop() {};
	var methods = ['assert', 'clear', 'count', 'debug', 'dir', 'dirxml', 'error', 'exception', 'group', 'groupCollapsed', 'groupEnd', 'info', 'log', 'markTimeline', 'profile', 'profileEnd', 'table', 'time', 'timeEnd', 'timeStamp', 'trace', 'warn'];
	var length = methods.length;
	var console = (window.console = window.console \|\| {});
	while (length--) {
	method = methods[length];
	if (!console[method]) {
	console[method] = noop;
