Website Accessibility and WCAG 2.2: A Practical Business Guide
A practical introduction to accessible website design for business owners, marketers and development teams.
Website accessibility means designing digital experiences that people with disabilities can use. It also improves usability for people on small screens, temporary injuries, slow connections and assistive technology.
WCAG 2.2 is organized around four principles: perceivable, operable, understandable and robust.
Perceivable
Provide text alternatives for meaningful images, captions for video, sufficient contrast and layouts that remain readable when enlarged.
Operable
Support keyboard navigation, visible focus, logical focus order, usable target sizes and accessible menus and dialogs.
Understandable
Use clear labels, consistent navigation, specific validation messages, plain language and predictable controls.
Robust
Use semantic HTML, correct form associations and tested dynamic interfaces. ARIA should not replace native HTML when a native control exists.
Important WCAG 2.2 additions
WCAG 2.2 added criteria related to focus appearance, focus not obscured, dragging movements, target size, consistent help, redundant entry and accessible authentication.
Accessibility and conversion
Accessibility supports clarity, form completion, mobile usability, error recovery and trust. Many accessibility improvements are also quality improvements.
Testing
Use automated scanning, keyboard tests, screen-reader tests, zoom and reflow tests, contrast review and human evaluation.
During Web Design and Development, Webz Fusion can define contrast, typography, form, focus and component standards from the beginning. Website Maintenance can include recurring accessibility checks.
