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.

Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

Element APIs

Getting box metrics

• elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent

  for (var u = 0; u < 9; u++) hash[ puzzle[ 3*((y/3)|0) + ((u/3)|0) ][ 3*((x/3)|0) + (u%3) ] ] = 1;
  
  var poss = [];
  for (var i = 1; i <= 9; i++) if (!(i in hash)) poss.push(i);
  return poss;

Styling native elements

Native HTML controls are a challenge to style. You can style any element in the web platform that uses Shadow DOM with a pseudo element ::pseudo-element or the /deep/ path selector.

video::webkit-media-controls-timeline {
  background-color: lime;
}

video /deep/ input[type=range] {
