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

javascript:(function(){var styles = document.querySelectorAll('link[rel=\'stylesheet\']'); for (var s = 0; s < styles.length; s++) {styles[s].mediax = styles[s].media;if (styles[s].media === 'only x') { styles[s].media = styles[s].mediax; } else if (styles[s].media !== 'print') {styles[s].media = 'only x';}}})();
