Recommandation WCAG 2.2
La version la plus récente des WCAG, introduisant 9 nouveaux critères de succès ciblant la malvoyance, l'accessibilité cognitive et les écrans tactiles.
Périmètre technique et finalité
Les WCAG 2.2 enrichissent la version 2.1 pour répondre aux usages mobiles actuels et suppriment le critère 4.1.1 devenu obsolète.
Exigences fondamentales et critères de succès
2.4.11 Focus Not Obscured (Minimum) (AA)
When an element receives keyboard focus, it must not be completely hidden by author-created content (such as sticky headers, cookies banners, or floating buttons).
2.4.12 Focus Not Obscured (Enhanced) (AAA)
When an element receives keyboard focus, no part of its focus indicator may be obscured.
2.4.13 Focus Appearance (AAA)
The focus indicator must have an area of at least 2px border or equivalent contrast ratio of 3:1 against surrounding colors.
2.5.7 Dragging Movements (AA)
Any function requiring a dragging movement (such as drag-and-drop kanban boards or sliders) must also offer a single pointer alternative (e.g., clickable up/down buttons).
2.5.8 Target Size (Minimum) (AA)
Interactive pointer targets must be at least 24 by 24 CSS pixels, or provide sufficient spacing to adjacent targets to prevent accidental clicks.
3.2.6 Consistent Help (A)
If a digital product provides help (contact form, chat widget, phone number, FAQ), the link or access point must appear in the same relative order across pages.
3.3.7 Redundant Entry (A)
Information previously entered by the user in a multi-step process must either be auto-populated or available for selection, reducing cognitive load.
3.3.8 Accessible Authentication (Minimum) (AA)
Authentication must not rely solely on cognitive function tests (such as memorizing passwords, solving math puzzles, or complex visual CAPTCHAs) without accessible alternatives (e.g., copy/paste support, password managers, or WebAuthn).
3.3.9 Accessible Authentication (Enhanced) (AAA)
Eliminates all cognitive tests and object recognition for authentication.
