High-Contrast Accessible Navbar

A liquid-glass navbar that refuses to trade beauty for accessibility. It layers a solid contrast scrim under the text, dual specular borders for physical edge definition, tuned text-shadows and a bold :focus-visible ring — so it passes WCAG 2.2 AA (4.5:1 body / 3:1 large) even over a bright, busy background. It also honours forced-colors mode.

## JavaScript
```js
/* No JavaScript — a solid contrast scrim under the frost guarantees WCAG AA over bright backgrounds; dual borders define the glass edge; a 4px :focus-visible ring plus forced-colors + prefers-contrast blocks cover accessibility modes. */
```

How this works

Under the frosted layer sits a semi-opaque dark scrim sized to the text, guaranteeing 4.5:1 contrast regardless of the photo behind. Links get a subtle text-shadow for extra separation, dual borders (outer hairline + inner highlight) define the glass edge, and :focus-visible paints a thick high-contrast ring. A forced-colors block maps to system colours.

Pure CSS. Every link is a 44px+ target with aria-current; nothing relies on colour alone; motion is minimal and reduced-motion-safe.

Make it yours

  • Tune the scrim opacity to hit your exact contrast ratio.
  • Thicken the focus ring / add offset for low-vision users.
  • Swap the scrim colour for light-on-dark contexts.

Gotchas — read before shipping

  • Never rely on the blur alone for contrast — always back text with a solid-enough scrim.
  • Keep :focus-visible highly visible; don't inherit a faint ring.
  • Support prefers-contrast + forced-colors, not just default.

Pure CSS; contrast scrim + focus ring work everywhere, backdrop-filter is the only progressive part.
