The Web Accessibility Initiatives (WAI), created by the World Wide Web Consortium (W3C), defines digital accessibility as follows: “Web accessibility means that people with disabilities can use the web.
More precisely, they can perceive, understand, browse and interact with the web, and contribute to the web. Web accessibility also benefits others, especially the elderly population whose skills change with age.
Web accessibility includes all disabilities that affect access to the web, including visual, audio, physical, speech, cognitive, and neurological disabilities. Accessibility also includes people who have problems with computer hardware (very slow speed, old computer, lack of knowledge of how to use computer tools, etc.).
