Web Accessibility¶

Accessibility covers semantics, keyboard behavior, focus, ARIA, and contrast for UI surfaces.

Upstream references¶

• Web Content Accessibility Guidelines (WCAG) 2.2
• WAI-ARIA Authoring Practices Guide

What upstream owns¶

• WCAG success criteria
• ARIA widget patterns
• baseline accessibility semantics

What VCQA owns¶

• code-level detection mapping.
• minimum acceptance gates for UI stacks.

Detection signals¶

• web UI files such as index.html or *.tsx
• component libraries
• docs or app pages rendered in a browser

Composed standards¶

• React SPA

Combination-born guidelines¶

• React plus custom controls requires keyboard and focus behavior tied to component state.
• Docs KB plus search/navigation requires accessible document structure and skip-friendly headings.
• VS Code webviews need accessibility checks inside a constrained host shell.
