CSS E-commerce Coupon Code Card with Copy Button

A promo card built the way a store actually ships one: product shot, offer, a dashed voucher rail with SAVE20 set large in mono, and a copy button that confirms in place. The ticket notches are pure CSS radial gradients, and the terms line stays honest — the copy button is the payoff, not decoration.

## JavaScript
```js
const cpy12 = document.querySelector('.cpy-12');
if (cpy12) {
  const btn = cpy12.querySelector('.cpy-12__btn');
  const code = cpy12.querySelector('#cpy-12-code');
  const live = cpy12.querySelector('.cpy-12__live');
  let timer;
  btn.addEventListener('click', async () => {
    const value = code.textContent.trim();
    let ok = true;
    try { await navigator.clipboard.writeText(value); } catch { ok = false; }
    btn.dataset.state = ok ? 'copied' : 'idle';
    live.textContent = ok ? value + ' copied - apply it at checkout' : 'Copy blocked - select ' + value + ' and press Ctrl C';
    clearTimeout(timer);
    timer = setTimeout(() => { btn.dataset.state = 'idle'; live.textContent = ''; }, 2400);
  });
}
```

How this works

The ticket, without images. A 2 px dashed border in the accent hue over a 5 % tint of the same hue is the entire voucher metaphor — no cut-out graphics, and it re-tints itself in dark mode because both values derive from one token:

.cpy-12__ticket{
  border:2px dashed color-mix(in srgb,var(--accent) 42%,transparent);
  background:color-mix(in srgb,var(--accent) 5%,transparent);
  border-radius:1rem;}

Make the code selectable as one unit. Users who distrust copy buttons (or whose clipboard is blocked) will select the code by hand. user-select:all turns that into a single click instead of a careful drag:

.cpy-12__code{user-select:all; font-family:var(--mono);
  font-size:clamp(1.5rem,5vw,2.1rem); letter-spacing:.08em;}

Confirm without moving anything. The success message occupies a row that is always present but empty, so the card does not grow when the code is copied — important when the card sits in a grid of offers where one growing card shifts the rest.

Name the value in the announcement. On a page with three offers, Copied is useless. The live region says SAVE20 copied — apply it at checkout, which is unambiguous whether you hear it or read it.

Make it yours

  • Change the rail's weight with the 2px dashed border and the 42% mix — lighter reads premium, heavier reads discount.
  • Swap the dashed rail for a solid divider with a small scissors glyph if your brand is more playful.
  • Add an expiry countdown in the terms row — text only, so it never competes with the copy button.
  • Replace the photograph with a flat brand colour by removing the <img>; the layout is a two-column grid that collapses cleanly.
  • Stack the card vertically at all widths by setting grid-template-columns:1fr if it lives in a narrow sidebar.
  • For several offers, repeat the card in a grid and delegate the click handler once, as in demo 20.

Gotchas — read before shipping

  • Do not put the coupon in an <img> or a background: it cannot be copied, selected, translated or read aloud.
  • Avoid animating the card's height on success — in a grid of offers, one growing card pushes every neighbour.
  • A dashed border plus a shadow plus a gradient is one effect too many; the dashed rail carries the ticket metaphor on its own.
  • Announce the code itself. Copied alone is ambiguous on a page with multiple promos.
  • Keep the code in mono with generous letter-spacing: SAVE20 in a proportional face invites SAVE2O transcription errors.
  • Never auto-copy on page load. Clipboard writes require a user gesture, and silently overwriting a clipboard is hostile.

Browser support

Floor set by :has(), oklch(), color-mix(), backdrop-filter, text-wrap as this demo is written. The core technique itself goes back further — Chrome 66+.

Dashed borders and user-select work everywhere. Clipboard API versions as listed (secure context required). color-mix() needs Chrome 111 / Safari 16.2 / Firefox 113 for the ticket tint and degrades to the solid fallback declared first.
