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

Open Source code doesn’t always come in big complex packages. At ProPublica we sometimes share small, simple snippets of using GitHub "Gists." These Gists range from single-byte file delimiters to an entire JavaScript framework for making stepper graphics. They rarely have documentation and don’t even always have names, but they can be super-useful. Here are some we’ve shared over the past few years:

• A simple way to grab remote template elements in your Rails app (after Brian Boyer's RemoteSnippets) https://gist.github.com/1664329
• A single byte gist that contains ASCII character 28, which the FEC uses as a field delimiter. https://gist.github.com/2191300
• A [quine](http://en.wikipedia.org/wiki/Quine_(computing) in Ruby https://gist.github.com/523940
• Check links on a page using JavaScript [https://gist.github.com/
