## JavaScript
```js
(() => {
  const root = document.querySelector('.cb-28');
  const btn = root && root.querySelector('.cb-28__btn');
  const slip = root && root.querySelector('.cb-28__slip');
  if (!btn) return;
  const fortunes = [
    'The bug you fear is a typo you already fixed.',
    'Ship the small thing today; the big thing will follow.',
    'A stranger will use your CSS at 3am and be grateful.',
    'Delete one thing before you add three.',
    'Your next idea arrives while you are away from the keyboard.',
  ];
  let open = false;
  let last = -1;
  const pick = () => {
    let i = last;
    while (i === last) i = Math.floor(Math.random() * fortunes.length);
    last = i;
    return fortunes[i];
  };
  btn.addEventListener('click', () => {
    open = !open;
    root.classList.toggle('is-open', open);
    btn.setAttribute('aria-expanded', String(open));
    slip.textContent = open ? pick() : '';
  });
})();
```

How this works

The cookie is one element split into two clip-path halves that share a fracture line, so the crack edges match perfectly:

.cb-28__half--l{ clip-path:polygon(0 0,52% 0,46% 50%,52% 100%,0 100%); }
.cb-28__half--r{ clip-path:polygon(52% 0,100% 0,100% 100%,52% 100%,46% 50%); }
.cb-28.is-open .cb-28__half--l{ rotate:-9deg; translate:-1.1rem 0; }
.cb-28.is-open .cb-28__half--r{ rotate:9deg;  translate:1.1rem 0; }

The slip starts hidden behind the cookie at scale:.6 with zero height and slides up on open; the JS picks a fortune, writes it into the live region and toggles one class:

btn.addEventListener('click', () => {
  open = !open;
  root.classList.toggle('is-open', open);
  btn.setAttribute('aria-expanded', String(open));
  slip.textContent = open ? pick() : '';
});

The label sits in flow below the cookie rather than on top of it: a centred word inside the shell gets sliced in half the moment the crack opens — the layout trap in any split-open control. aria-expanded on the button plus aria-live="polite" on the slip means a screen-reader user gets "expanded" and then the fortune text — the animation is purely decorative on top of a working disclosure.

Make it yours

  • Replace the fortunes array with your own strings — release notes, tips, quotes, or a single fixed message.
  • Change the fracture by editing both polygons' midpoints together; they must stay complementary.
  • Make it one-shot by removing the toggle and disabling the button after opening.
  • Swap the slip for an image or a coupon code; the container is a normal flex box.

Gotchas — read before shipping

  • A reveal that only animates is invisible to assistive tech — aria-expanded plus a live region is the accessible core, and the animation is the garnish.
  • aria-live regions must exist in the DOM before the text changes; creating the element and setting text in the same tick often fails to announce.
  • The two halves must be siblings inside a non-clipping parent, or the rotation will be cut off at the button's edge.
  • Never centre a label inside a shape that splits apart — the fracture runs straight through the type. Keep the caption outside the cracking zone (here, in flow below it).
  • Random content should never be the only copy that matters; keep the button's own label descriptive ("Open your fortune").
  • Don't animate height on the slip; scale and opacity keep it off the layout thread.

Floor set by oklch(), color-mix() as this demo is written. The core technique itself goes back further — Chrome 104+.

clip-path polygons and individual transform properties (Chrome 104 / Safari 14.1 / Firefox 72) cover everything; aria-live and aria-expanded are platform features.
