Accessibility

Klokk is built to WCAG 2.1/2.2 Level AA — the conformance level behind EN 301 549 and Germany’s BFSG and BITV 2.0. Accessibility is treated as a build requirement, not an afterthought: every screen ships keyboard-operable and screen-reader-labelled.

  • Full keyboard operation — every control is reachable and operable without a mouse, with a clearly visible focus ring; a “skip to content” link jumps past the navigation.
  • Screen-reader support — semantic landmarks and headings, labelled icon-only buttons, ARIA live regions that announce page changes and save/error messages, and the active nav item exposed via aria-current.
  • Dialogs — modals are proper role="dialog" with focus trapped while open, restored on close, and Escape to dismiss.
  • Readable by default — text contrast meets the 4.5:1 minimum in light and dark themes, layouts reflow to small screens, and nothing relies on colour alone.
  • Respects preferences — honours the OS prefers-reduced-motion setting, and the page language is declared so screen readers pronounce German and English correctly.
