Web Accessibility

Note:
This page was created for use in my former classes. It is only occasionally updated resulting in many links being more of historical rather than current usefulness. Over time many links will suffer link rot.

"The power of the Web is in its universality.
Access by everyone regardless of disability is an essential aspect."

Tim Berners-Lee
W3C Director and inventor of the World Wide Web
