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

// Here is a proposal for minimalist JavaScript classes, humbly offered.

// There are (at least) two different directions in which classes can be steered.
// If we go for a wholly new semantics and implementation, then fancier classical
// inheritance can be supported with parallel prototype chains for true inheritance
// of properties at both the class and instance level.

// If however, we keep current JavaScript prototype semantics, and add a form that
// can desugar to ES3, things must necessarily stay simpler. This is the direction
// I'm assuming here.
