## JavaScript
```js
const nav = document.getElementById('nav14');
  const btn = document.getElementById('nav14Toggle');
  btn.addEventListener('click', function() {
    const isOpen = nav.classList.toggle('is-open');
    btn.setAttribute('aria-expanded', isOpen);
    document.body.style.overflow = isOpen ? 'hidden' : '';
  });
```

How this works

The overlay is a fixed position: fixed; inset: 0 element with z-index: 200, initially hidden with opacity: 0; pointer-events: none; visibility: hidden. A JS click on the hamburger button adds an .is-open class that transitions opacity to 1 and sets pointer-events back. The menu links each have a staggered animation-delay so they cascade in from the bottom sequentially on open. Closing removes the class and the reverse CSS transition plays automatically.

Make it yours

  • Adjust the stagger by changing the per-link animation-delay increments — 0.05s between links is subtle; 0.12s is more theatrical.
  • Change the entrance direction by swapping translateY(30px) to translateX(-40px) for a horizontal slide.
  • Add a close button inside the overlay by targeting it with the same JS toggle.
  • Use a different overlay background — a dark gradient or a blurred screenshot of the page content adds depth.

Gotchas — read before shipping

  • Remember to trap focus inside the overlay when it's open — without a focus trap, keyboard users can tab to links behind the overlay.
  • The visibility: hidden toggle is important alongside opacity — opacity alone still lets screen readers announce the hidden links.
  • On iOS Safari, position: fixed overlays can jump when the virtual keyboard opens — test with an input inside the overlay.

All techniques are widely supported. The CSS animation stagger is standard and requires no prefixes in modern browsers.
