Essential Components of Web Accessibility

This document shows how Web accessibility depends on several components working together and how improvements in specific components could substantially improve Web accessibility. It also shows how the WAI guidelines address these components.

It is essential that several different components of Web development and interaction work together in order for the Web to be accessible to people with disabilities. These components include:

  • content - the information in a Web page or Web application, including:
    • natural information such as text, images, and sounds
    • code or markup that defines structure, presentation, etc.
  • Web browsers, media players, and other "user agents"
  • assistive technology, in some cases - screen readers, alternative keyboards, switches, scanning software, etc.
  • users' knowledge, experiences, and in some cases, adaptive strategies using the Web
  • developers - designers, coders, authors, etc., including developers with disabilities and users who contribute content
  • authoring tools - software that creates Web sites
  • evaluation tools - Web accessibility evaluation tools, HTML validators, CSS validators, etc.

Above part is not written by me (taken from W3C site). Actually I am reading about WAI. And I was just thinking about those projects in which I have worked. But seriously WAI is not a small topic. Few topics are covered and I don’t know about other points…

Can anyone help me about WAI implementation? Actually I am still confused about implementation part. Any case studies or ……..
