Video Player Overlay Close Button

The picture-in-picture / embedded-player dismiss: a close button that fades out with the rest of the player chrome after 2.4s of inactivity and reappears the instant the pointer moves — YouTube's idle-hide behaviour — with a scrim gradient behind the top bar so the × survives bright footage. Keyboard focus ALWAYS reveals the chrome.

## JavaScript
```js
(() => {
  const player = document.getElementById('ccb-09-player'); if (!player) return;
  const IDLE = 2400; let timer;
  const wake = () => {
    player.classList.remove('is-idle');
    clearTimeout(timer);
    timer = setTimeout(() => player.classList.add('is-idle'), IDLE);
  };
  player.addEventListener('pointermove', wake);
  player.addEventListener('pointerdown', wake);
  wake();                                        // arm the timer on load
})();
```

How this works

Chrome visibility is one class: .is-idle sets the top bar to opacity:0 and — critically — pointer-events:none, so a hidden button can never swallow a tap meant for the video. JS resets a 2.4s timer on pointermove/pointerdown over the player; the timer adds the class, movement removes it.

The accessibility catch most players miss: :focus-within on the player overrides the idle state — .player:focus-within .topbar{opacity:1; pointer-events:auto} — so a keyboard user Tabbing to the close button always sees it, no pointer required. The top bar sits on a linear-gradient(180deg, rgba(0,0,0,.6), transparent) scrim, the standard trick for white-sky footage; the button itself is the lightbox recipe at 36px.

Make it yours

  • Idle delay via the JS constant (2.4s matches YouTube; shorten for PiP miniplayers).
  • Scrim strength: .6 → .8 alpha for consistently bright content.
  • Add title text in the top bar — the scrim already budgets for it.
  • For true PiP, pin the player fixed bottom-right and add a drag handle.

Gotchas — read before shipping

  • pointer-events:none on hidden chrome is not optional — invisible-but-clickable buttons steal video taps (a real, common bug).
  • :focus-within must beat .is-idle in the cascade — put it after, or use :where() on the idle rule to zero its specificity.
  • Fade with opacity only; display:none would drop keyboard focus mid-Tab and strand the user.

:focus-within is 2018+; everything else is opacity, gradients and a timer.
