What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout. This is also called reflow or layout thrashing, and is common performance bottleneck.

Element

Box metrics

elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent
elem.clientLeft, elem.clientTop, elem.clientWidth, elem.clientHeight
elem.getClientRects(), elem.getBoundingClientRect()

Frontend Development

Attention: if you attempt to fork this gist, github will think that you are a spammer and you will have to confirm that you are human with them. Apparantly there are too many links in this list. Also I update it rather frequently (see revisions on the left), so it's probably wise to not fork it anyway.

	var trigger = function (el, type) {
	var event;
	if (document.createEvent) {
	event=document.createEvent('HTMLEvents');
	event.initEvent(type,true,true);
	} else {
	event=document.createEventObject();
	event.eventType=type;
	}

	$(".test_range").ionRangeSlider({
	min: 100,
	max: 1000,
	from: 550
	step: 10
	});
