“Web accessibility” refers to content designed so that disabled users can access it. Accessibility involves a wide range of disabilities, including visual, auditory, physical, speech, cognitive, language, learning, and neurological.
Accessibility overlaps with other disciplines, such as responsive web design, usability, and search engine optimization. As a result, accessible websites can have an increased audience reach, better search results, and demonstrate social responsibility to users.
