Learn the purpose of WCAG 2.2 and how its accessibility principles affect real websites.
Understand the foundation
WCAG 2.2 is a W3C Recommendation that builds on earlier WCAG versions. It organizes accessibility requirements around four principles: content should be perceivable, operable, understandable, and robust.
Look at the real user experience
Perceivable content gives users alternatives for information presented visually or through audio. Examples include text alternatives for informative images, captions, and content that remains usable when enlarged.
Use standards and testing thoughtfully
Operable interfaces support keyboard use, visible focus, sufficient time, and controls that can be activated without relying on a single input method. Menus, dialogs, and custom controls deserve careful testing.
Build a repeatable process
Understandable experiences use clear labels, predictable navigation, helpful instructions, and error messages that explain how to recover. Robust content uses semantic markup and patterns that work with a range of user agents and assistive technologies.
Practical next steps
WCAG 2.2 adds criteria including focus appearance and target-size-related requirements, among others. Determine which version is required by the relevant law, contract, or procurement rule rather than assuming the newest version automatically applies everywhere.
