Abstract:

The inaccessibility of web content can have a significant impact on the lives of individuals with disabilities. Many people without disabilities are ignorant of the importance of the issue to those who are directly affected. They are also often ignorant of the tremendous benefit that accessible web content can be. Accessible web sites offer independence to individuals with disabilities that would otherwise not have it.
