Web Content Accessibility Guidelines (WCAG) 2.1 Heuristics

Web Content Accessibility Guidelines (WCAG) 2.1 covers a wide range of recommendations for making Web content more accessible.

Content more accessible to people with disabilities, including blindness and low vision, deafness and hearing loss, limited movement, speech disabilities, photosensitivity, learning disabilities and cognitive limitations; but will not address every user need for people with these disabilities. These address accessibility on desktops, laptops, tablets, and mobile devices. They will also often make Web content more usable to users in general.
