Warning::
Skip navigation link is missing (WCAG 2.4.1)
Add a skip link as the first focusable element so keyboard users can bypass repeated navigation.
Page Structure — as a screen reader sees it
BANNER header NAV "Hauptnavigation" MAIN ASIDE "Erscheinungstermin" CONTENTINFO footer

Add a skip link as the first focusable element so keyboard users can bypass repeated navigation.

Why this matters

Without a skip-nav link, keyboard users tab through every nav item before reaching content — every page, every visit.

Learn more ▾

WCAG 2.4.1 (Bypass Blocks) requires a mechanism to skip past repeated content. The standard implementation is a 'Skip to main content' link that's the first focusable element, visually hidden until focused. Three lines of HTML + four of CSS.

Browser-chrome `theme-color` meta tag present
The page sets `<meta name="theme-color" content="...">`, which Android Chrome uses to tint the status bar and iOS Safari uses for the toolbar background. Brand polish that costs nothing and Just Works.
Info::
Viewport `viewport-fit=cover` -- supports notched / dynamic-island devices
The viewport meta declares `viewport-fit=cover`, which lets the page draw into the safe-area edges (notch, dynamic island, home indicator) on iPhone X+ devices. Pair with `env(safe-area-inset-*)` CSS to keep critical UI inside the inset rectangle while letting backgrounds extend edge-to-edge.
