Accessibility glossary

ADA (Americans with Disabilities Act)

A 1990 U.S. civil-rights law prohibiting discrimination based on disability, increasingly applied to websites and apps.

Title III of the ADA covers “places of public accommodation.” Courts and the DOJ have repeatedly treated business websites as covered, using WCAG as the yardstick.

Most ADA web risk in practice comes from private demand letters citing WCAG failures — see our lawsuit data.
