Standards and legal context

Do not treat WCAG and law as interchangeable.

WCAG provides technical criteria. Section 508 and ADA regulations apply in different jurisdictions and may incorporate a particular WCAG version or use WCAG as a benchmark.

Educational use: 508 Dev provides technical accessibility education, not legal advice. Legal requirements depend on jurisdiction, facts, and current authority.
