Introduction to Web Accessibility and W3C Standards by W3C Web Accessibility Initiative (WAI)


They are a set of recommendations for making Web content more accessible, primarily for people with disabilities—but also for all user agents, including highly limited devices, such as mobile phones.

According to many definitions, a disability is an impairment that may be cognitive, developmental, intellectual, mental, physical, sensory, or some combination of these.

In computing, a user agent is software that is acting on behalf of a user.
