Digital Coupon / Discount Card

A ticket-shaped discount card whose promo code sits blurred behind a frosted strip — move your cursor (or focus it) and a Liquid Glass lens travels across the strip, sharpening and magnifying the code beneath it like a scratch-off reveal. Perforated edge notches and a dashed tear line complete the ticket look.

  const lens = document.querySelector('#lg-15-lens');
  const lensCode = lens && lens.querySelector('.lg-15__lenscode');
  const copy = document.querySelector('#lg-15-copy');

  const code = document.querySelector('#lg-15-code');
  if (!wrap) return;
  wrap.addEventListener('pointermove', (e) => {
    const r = wrap.getBoundingClientRect();
    const x = Math.max(0, Math.min(r.width, e.clientX - r.left));
    wrap.style.setProperty('--lx', x + 'px');
    if (lensCode) lensCode.style.left = (r.width/2 - x) + 'px';
  });
  wrap.addEventListener('focus', () => ticket.classList.add('is-reveal'));
  wrap.addEventListener('blur', () => ticket.classList.remove('is-reveal'));
  copy.addEventListener('click', () => {
    const text = code.textContent.trim();
    const done = () => { live.textContent = 'Copied “' + text + '” to clipboard'; };
    if (navigator.clipboard && navigator.clipboard.writeText) navigator.clipboard.writeText(text).then(done).catch(done);
    else done();
  });
})();
```

How this works

The code lives on the base layer under a backdrop-filter:blur() frosted strip, so it reads as obscured. A circular lens element follows the pointer along the strip; where it sits, a masked sharp copy of the code shows through (an un-blurred window) plus an SVG displacement rim, so the code snaps into focus under the glass droplet. The ticket notches are radial-gradient cut-outs; the tear line is a dashed border.

The code is real text (in the DOM, screen-reader readable regardless of blur); the reveal is progressive enhancement. A 'Copy code' button gives a non-hover path, with aria-live feedback.

Make it yours

  • Set the lens size via --r and reveal sharpness via the blur radius.
  • Recolour the ticket + accent via --accent.
  • Swap the code, discount value and expiry text in the markup.

Gotchas — read before shipping

  • Keep the real code in the DOM as text — never bake it into an image — so it stays accessible and copyable.
  • Provide the Copy button so keyboard/touch users aren't forced to 'hover to reveal'.
  • Don't over-blur the base or the pre-reveal state looks broken rather than teasing.

Floor set by oklch(), color-mix(), backdrop-filter as this demo is written. The core technique itself goes back further — Chrome 76+.

Pointer-lens reveal is enhancement; the code is always readable and copyable via the button without JS.
