Abstract:

Since the discourse over creating accessible Web pages began, the standards organizations that helped inform the new Federal rules have stressed the separation of design and content. If the Internet is to reach its full potential, content will need to be authored so that it can be rendered by a broad array of devices: browsers, assistive technologies, PDAs, and devices that have yet to be imagined. Only by separating content from design will this be possible. By following the rules in Section 508, you will be doing more than providing access for those with disabilities; you will be creating content that is available to all users, no matter what devices are used to read it.
