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

Setup

Assuming project is SOME/PROJECT And you are FOO

You will need to do the following one time only:

• Fork SOME/PROJECT repository under your namespace.
• Navigate to https://github.com/FOO/PROJECT/wiki
• Hit Create the first page. You will get an error (that's ok!)
