Introduction to WCAG 2.2

Background on WCAG 2

Web Content Accessibility Guidelines (WCAG) 2.2 defines how to make web content more accessible to people with disabilities. Accessibility involves a wide range of disabilities, including visual, auditory, physical, speech, cognitive, language, learning, and neurological disabilities.

                        Key Evolution:
                        Built on WCAG 2.0 (2008) and WCAG 2.1 (2018)
Adds new success criteria for cognitive, low vision, and mobile users
Maintains backwards compatibility with previous versions
Addresses emerging web technologies and user needs

                    

WCAG 2.2 Enhancements

WCAG 2.2 extends WCAG 2.1 by adding new success criteria, definitions, and guidelines to address user needs that were not sufficiently covered in previous versions.

                        New Success Criteria in WCAG 2.2:
                        Focus Not Obscured (Minimum & Enhanced)
Dragging Movements
Target Size (Minimum)
Consistent Help
Redundant Entry
Accessible Authentication (Minimum & Enhanced)
