 * Add to bookmark
 * Several tests are necessary in order for this "simple" action to work in most of the browsers

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

• Update package.json, set version to a prerelease version, e.g. 2.0.0-rc1, 3.1.5-rc4, ...
• Run npm pack to create package
• Run npm publish <package>.tgz --tag next to publish the package under the next tag
• Run npm install --save package@next to install prerelease package
