Web accessibility is for people that have disabilities so that they can use the Web. This is done in many different ways due to a large number of different disabilities and means that people with disabilities can interact and contribute to the Web. Web accessibility can also help others without disabilities, for example, the elderly.
The different areas that web accessibility can help include; visual, auditory, physical, speech, cognitive, and neurological disabilities. Millions of people have disabilities that affect their use of the Web. Currently most Web sites and web software have accessibility problems that make it very difficult for many people with disabilities to use the Web. As more accessible Web sites and software become available, people with disabilities are able to use the Web more easily.
Web accessibility also benefits people without disabilities. For example, a key principle of Web accessibility is designing Websites and software that are flexible to meet different user needs. This can also benefit people without disabilities in certain situations, people with an injury such as a broken arm, such as people using a slow Internet connection, and people with changing abilities due to aging.
