HTML5 Sanity Check

Most of us are excited about HTML5 and all the benefits it will bring. Overly excited maybe is a more accurate term, which includes myself. We as a community need a “sanity check” about the readiness of HTML5 and its accessibility because:

  1. The spec isn’t complete (2012 for Candidate Recommendation) thus requirements may still change.
  2. The browsers are in the middle of implementation and much accessibility support isn’t provided yet.
  3. There are many accessibility issues remaining such as Canvas in general; no semantic information to assistive technology for many elements; keyboard access lacking in audio & video controls in most conditions.

The web site HTML5Accessibility.com is a great place to learn about these issues for each major web browser.
