Tailwind Drawer Close Button with Native Dialog

A slide-over built on <dialog>: the browser traps focus, Esc closes it and focus returns to the opener for free. Tailwind v4 animates both directions with open:translate-x-0, starting:open:translate-x-full and transition-discrete — the entry and the exit, with the dialog still painted while it slides out. The port turns the demo into a real filter drawer with an Apply footer.

What changed in the port

Which parts became utilities, which stayed CSS, and why.

  • :not([open]), @starting-style and ::backdrop rules became open:, starting:open: and backdrop: variants on the dialog itself; transition: display .35s allow-discrete became transition-discrete.
  • UI upgrade from the CSS original: the drawer is now a working filter panel — labelled checkboxes with 44px rows, a pinned Apply footer and a header divider — instead of a paragraph of placeholder text.
  • UI upgrade: the close button grew from 40px to 44px, the opener carries a filter icon, and the button's label says what it closes ("Close filters").

## JavaScript
```js
(() => {
  const drawer = document.getElementById('tcb-10-drawer');
  if (!drawer || drawer.dataset.wired) return;
  drawer.dataset.wired = '1';
  document.getElementById('tcb-10-open').addEventListener('click', () => drawer.showModal());
  document.getElementById('tcb-10-close').addEventListener('click', () => drawer.close());
  document.getElementById('tcb-10-apply').addEventListener('click', () => drawer.close());
  drawer.addEventListener('click', (e) => { if (e.target === drawer) drawer.close(); });
})();
```

How this works

Three states, three variants.

translate-x-full                 closed (and the exit target)
open:translate-x-0               open
starting:open:translate-x-full   the frame before open

Why transition-discrete. Closing a dialog flips display to none and removes it from the top layer instantly. transition-behavior: allow-discrete on display and overlay defers both until the slide finishes.

Make it yours

  • Left drawer: start-0 end-auto -translate-x-full.
  • Bottom sheet: inset-x-0 bottom-0 top-auto h-auto translate-y-full open:translate-y-0.
  • Width: w-[min(20rem,85vw)] → w-[min(28rem,92vw)].

Gotchas — read before shipping

  • Use showModal(), not show() — only the modal form gets ::backdrop, the focus trap and inert siblings.
  • Firefox does not yet animate overlay; the drawer still slides but may leave the top layer a frame early.

Browser support

117+17.5+129+117+

Entry/exit animation needs @starting-style + transition-behavior; older engines open and close instantly, which is still correct.
