“Web accessibility means that web, design and content developers are creating websites and web applications without barriers to people with disabilities, so that people with disabilities can navigate, understand, perceive and interact with the Web. The disabilities that are addressed by web accessibility include physical, visual, auditory, speech, cognitive and neurological disabilities. Currently, many websites are not accessible for people with disabilities.
Web accessibility can also benefit people without documented disabilities such as older people who might have vision challenges.”
