NOTE: This is no longer an experiment! You can use the accessibility inspector in Chrome Devtools now, including a fantastic color contrast inspection tool. Read more: https://developers.google.com/web/updates/2018/01/devtools#a11y

Just like any good element inspector helps you debug styles, accessibility inspection in the browser can help you debug HTML and ARIA exposed for assistive technologies such as screen readers. There's a similar tool in Safari (and reportedly one in Edge) but I like the Chrome one best.

As an internal Chrome experiment, this tool differs from the Accessibility Developer Tools extension in that it has privileged Accessibility API access and reports more information as a result. You can still use the audit feature in the Chrome Accessibility Developer Tools, or you could use the aXe Chrome extension. :)

To enable the accessibility inspector in Chrome stable:

	<?php

	// Prevent content sniffing attacks such as http://mths.be/bst.
	header('X-Content-Type-Options: nosniff');

	// Note: The user-provided callback name must be filtered to prevent attack
	// vectors. This script simply removes any symbols other than `[a-zA-Z0-9$_]`
	// from the input. Sadly, this blocks the use of some valid JavaScript
	// identifiers, and also accepts a few invalid ones. See
	// http://mathiasbynens.be/notes/javascript-identifiers for details.

	Positioning Relatives
	In 1958, English pictorial photographer Henry Peach Robinson created the world's first photomontage by combining five different negatives to make one complete print of a young girl on her deathbed. “Fading Away”—Robinson's first and most famous composite photo—depicts a young girl dying of consumption and was controversial when it was exhibited, with many believing it was not a suitable subject for photography.

	Box Model
	The Barbie doll was invented in 1959 by Ruth Handler (co-founder of Mattel), whose own daughter was called Barbara. Barbie was introduced to the world at the American Toy Fair in New York City. Barbie's job was teenage fashion doll. The full name of the first doll was Barbie Millicent Roberts, from Willows, Wisconsin.
