DEFINITION

Web Content Accessibility Guidelines 2.2 (W3C, October 2023) adds 9 new success criteria over 2.1 and obsoletes one (4.1.1 Parsing). The key additions: 2.4.11 and 2.4.12 Focus Not Obscured (sticky headers and cookie banners must not hide the focused element), 2.4.13 Focus Appearance (contrast and size rules for the focus ring), 2.5.7 Dragging Movements (every drag needs a single-pointer alternative), 2.5.8 Target Size minimum 24x24 CSS pixels, 3.2.6 Consistent Help, 3.3.7 Redundant Entry (do not ask for the same data twice), 3.3.8 and 3.3.9 Accessible Authentication (no cognitive-test logins like puzzles). After 28 June 2025 the European Accessibility Act makes WCAG-level accessibility mandatory for B2C digital products, in practice WCAG 2.2 AA.

RELATED TERMS06
  • SSR (Server-Side Rendering)→

    HTML rendered by the server per-request, fresh for every user. Ideal for dynamic content (dashboards), but slower than SSG.

  • SSG (Static Site Generation)→

    Pages are produced at build time as HTML and served from a CDN. Near-zero TTFB. DField's own site runs this way across 111+ pages.

  • ISR (Incremental Static Regeneration)→

    SSG + timed regeneration: the HTML is static but regenerates on a schedule. Ideal for blog content · freshness with CDN speed.

  • Edge rendering→

    Code runs at the CDN edge closest to the user (Cloudflare Workers, Vercel Edge). Dynamic responses with ~10–50 ms TTFB.

  • RSC (React Server Components)→

    React components that run exclusively on the server and never ship to the browser. Result: less client-side JS and faster hydration.

  • LCP (Largest Contentful Paint)→

    Time until the largest visible element paints. Google Core Web Vitals passes under 2.5s · we usually land marketing pages under 1s.
