Checks a HTML document and detects violations of a defined coding standard. Comes with standards that cover the three conformance levels of WCAG 2.0 and the U.S. Section 508 legislation. An auditor interface is provided by a bookmarklet to let you try out these accessibility checks on any web page.
Accessibility of web pages can be hard to observe. These bookmarklets help web developers and designers see the “big picture” regarding web accessibility.
The bookmarklets do this by:
•Making otherwise hidden accessibility features on web pages (like ARIA landmarks, roles, labels and descriptions and alternative text for non-text objects) more visible
•Showing whether HTML markup (like lists, headings, label elements, and appropriate landmark roles) is used with proper semantics for accessibility
•Flagging elements or regions on web pages where information that could improve accessibility (like elements not contained in landmarks, image alt text or long descriptions, list accessible names or descr
Offering usability for Users without Mouse is one of the biggest and most important Steps when building accessible Websites. While testing for Keyboard Accessibility you might find yourself very often in Situations like “Where is my Cursor?” or “What Element has the Focus right now?”. Especially when Elements get moved offscreen things might end up confusing. To install the Bookmarklet simply drag the following Link into your Bookmarks.
here you can run it on every Page by simply clicking on it.
Firefocus is a simple Firebug extension that tracks the element that currently has focus. Its primary purpose is to assist the debugging of advanced keyboard implementations without having to rely on platform specific tools such as MSAA Inspect.
This bookmarklet will place a big red border around links that do not include an href attribute. Simply drag the link to your browser’s bookmark bar and then click it when you want to test a page. It will draw a red border around any links that do not have an href attribute.

This set of tools allows you to check for several aspects of Web accessibility that other tools do not. It is not designed to replace any other tools, but rather to supplement them. This set of tools will allow you to:
•View page headings, including hidden label text
•View ARIA Landmarks, plus any accompanying aria-label or aria-labelledby text
•View internal links, both their source and their target ◦If the target link does not have an explicit tabindex value set, an asterisk will appear next to the link count and the target link will indicate it as well
•View any tabindex values
•View any ARIA roles (other than landmarks) and ARIA attributes
•Force the visual keyboard focus to always be seen (useful for keyboard testing.
•View any language attributes and what parts of the page they apply to.
This is the basic “Validate Page” Bookmarklet. It simply submits the URL for the currently viewed page to the Nu Markup Validation Service for processing. Results appear in the same window.Validate Page (New Window)Like the last Bookmarklet, this also submits the URL of the current page to the Nu Markup Validation Service for processing, but this version will show the results in a new window (tab).Validate Page…Puts up a dialog with a text entry field where you can type in the URL of a page you would like to Validate. The results appear in the current window.Validate Page… (New Window)Same as above but shows results in a new window (tab).
Zomigi created two simple bookmarklets to reveal whether CSS background images are being used in an inaccessible way on a page. Use them yourself, or help me learn how to improve them.
Paul J Adam accessibility Evangelist has created a set of bookmarklets that will help identify few accessibility bugs easily. These bookmarklets also work great on mobile web with both Chrome & Firefox.
The process of testing for accessibility (a11y) is often tedious and confusing. In many cases, developers must have some prior accessibility knowledge in order to make sense of the results.
Instead, tota11y aims to reduce this barrier of entry by helping visualize accessibility violations (and successes), while educating on best practices.
