The 4 Principles of Web Accessibility
Perceivable
Content must be presented in a way that everyone can perceive it, with alternatives like text for images or captions.
Operable
The web must be functional with keyboard, mouse, or assistive technologies, avoiding barriers like strict time constraints.
Understandable
Information must be clear and easy to understand, with consistent instructions and errors that are easy to correct.
Robust
Content must work with various technologies, including assistive tools, and remain accessible over time.
WCAG - Conformance Levels

Level AA

Level AAA
