The Web technology platform is a collection of web related media types that are applicable to web based applications, sites, and documents. The Web technology platform covers the following areas:

  1. Web accessibility requirements
  2. The user impact for individual requirements
  3. The code level enhancements required for web accessibility
  4. Evaluation techniques that should be used during development and testing phases

The web technology platform is divided into general areas of accessibility practice. For example, the images section provides information on accessibility issues and techniques relating to Images. Each media type such as images is broken into best practices. Each best practice is split into sub-sections relating to a best practice name, short description of the best practices (including user impact), compliant and non-compliant examples, remediation recommendations and different evaluation techniques. Each best practices in the Web technology platform is associated with one or more accessibility standards. These accessibility standards include but are not limited to Section 508 of the US Rehabilitation Act, WCAG 1, and WCAG 2.

HTML5 is the latest version of the HTML specification from the World Wide Web Consortium (W3C). The HTML5 specification is a work in progress and is not yet a full recommendation of the W3C. HTML5 however, is widely used and supported among browsers although not all of HTML5 is supported and browser support is not equal. Support for HTML5 by assistive technology is progressing with differing support levels among assistive technology.

A number of HTML5 techniques are Section 508 compliant while others are not without redundant markup for users of assistive technology. Testers should focus on the core requirements discussed in this course and how they work with a broadest of assistive technology and accessibility features rather than making a determination of Section 508 compliance based on use or lack of use of HTML5 techniques. Below are several HTML5 techniques and indicators of HTML5 redundant methods that testers should be aware of.
