According to ADA.gov, “Title III prohibits discrimination on the basis of disability in the activities of places of public accommodations (businesses that are generally open to the public and that fall into one of 12 categories listed in the ADA, such as restaurants, movie theaters, schools, day care facilities, recreation facilities, and doctors’ offices) and requires newly constructed or altered places of public accommodation—as well as commercial facilities (privately owned, nonresidential facilities such as factories, warehouses, or office buildings)—to comply with the ADA Standards.”
Generally speaking, most businesses, private and public, fall under Title III. These regulations are the basis for the WCAG 2.1 guidelines. While at one time the focus was on accessibility for physical storefronts, the online world is now seen to be just as relevant. Considering the volume of ecommerce and general activities we rely on the internet for on a daily basis, it is completely understandable that steps are being taken to ensure that everyone has the same access to this robust digital ecosystem.
