WCAG (Web Content Accessibility Guidelines) is the international standard for web accessibility, published by the W3C. It defines how to make web content accessible to people with disabilities including visual, auditory, motor, and cognitive impairments. WCAG has three conformance levels: A (minimum), AA (standard, legally required in many jurisdictions), and AAA (enhanced). The most commonly referenced requirement is color contrast: text must have a 4.5:1 contrast ratio against its background for WCAG AA compliance, or 7:1 for AAA. Other requirements cover keyboard navigation, screen reader compatibility, text alternatives for images, and many more.
