var mq = window.matchMedia("(min-width: 480px)");
  
	if (mq.matches) {

	// media query event handler
	if (matchMedia) {
		var mq = window.matchMedia("(min-width: 480px)");
		//mq.addListener(WidthChange);
		WidthChange(mq);
	}
	// media query change
	function WidthChange(mq) {
		if (mq.matches) {
			// window width is at least 480px. do this code
			
		}
