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

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] {

Fixing your skip links.

Read Damon Muma on this. He proposes the following jQuery solution (inspired by Thompson, fixed by me):

// Apply focus properly when accessing internal links with keyboard in WebKit browsers.
$("a[href^='#']").not("a[href='#']").click(function() {
   $("#"+$(this).attr("href").slice(1)+"").focus();
});
