Useful 10 minutes of WAI ARIA

I would like to post here a selection of resources that might help you start using ARIA in your web applications or websites – although ARIA is still a draft. you can start using it and some AT will know how to read it.

Introduction to WAI ARIA

Written by Gez Lemon for Opera Developer, this article is the best post you can start with. You will understand why ARIA was created in the first place and you will understand some basic terms like: roles, states, properties, and my favorite, ARIA regions.

ARIA Roles 101

Now that you know the basics of ARIA, you can start implementing ARIA roles in your applications. A full list of the roles definitions can be seen here, at the W3C WAI ARIA 1.0 specs website.

Supported states and properties

Learning about ARIA properties is the next logical step, and the W3C WAI ARIA specifications are really helpful even if the first impression is that you read the Constitution or something :)

Try some demos: ARIA Live Regions Screen Reader Demo

A very useful video by Aaron Cannon (from about using ARIA live regions in a correct way, the difference between aria-live=”polite” and aria-live=”rude” and how this whole thing works. You need to know that now aria-live=”rude” is not part of the specs anymore (it was really too rude) and we are left with “off”, “polite” and “assertive”.

You might wanna read ARIA and Progressive Enhancement written by Derek Featherstone for A List Apart because the small examples that you will find there will help you understand better the roles and the properties of ARIA.

If you wanna go back to reading the Constitution, WAI-ARIA 1.0 Authoring Practices – An author’s guide to understanding and implementing Accessible Rich Internet Applications is the next step, a page full of examples for you to learn from and best practices when it comes to implementing ARIA – pay special attention to Section 3: Keyboard and Structural Navigation, Section 4: Relationships and Section 5: Managing Dynamic Changes which is really really important.

Learn from examples

  • JQuery Widget Samples – a collection of common JQuery widgets made accessible with ARIA: sliders, progress bars, accordions, trees, carousels, tabs, etc….
  • jQuery-Accessible-RIA – adds some more ARIA examples: a form, a lightbox, tables, etc.

Aaron Gustafson also has a video with NVDA reading his now famous TabInterface.
