Tailwind Tooltip with Keyboard Shortcut Hint

An editor toolbar whose tooltips name the action and its shortcut. Pure Tailwind: group-hover: opens a tip after a 300ms intent delay, group-has-focus-visible: opens it instantly for keyboard users, and the arrow is an after: border triangle. Each tip is a real role="tooltip" wired with aria-describedby.

What changed in the port

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

  • .kbd-13__slot:hover .kbd-13__tip, .kbd-13__slot:focus-within .kbd-13__tip became group-hover: and group-has-focus-visible: on the tip itself.
  • The CSS arrow (::after border triangle) became five after: utilities.
  • UI upgrade: a 300ms hover-intent delay stops tooltips flickering as the pointer crosses the toolbar, while keyboard focus still opens instantly; mouse clicks no longer pin a tip open.
  • UI upgrade: an Italic button joins the toolbar, the toolbar gets role="toolbar", and tips invert in dark mode for contrast.

Demo: Tailwind Tooltip with Keyboard Shortcut Hint
Source: https://codefronts.com/snippets/tailwind-css-kbd-keys/tailwind-tooltip-keyboard-shortcut-hint/

An editor toolbar whose tooltips name the action and its shortcut. Pure Tailwind: group-hover: opens a tip after a 300ms intent delay, group-has-focus-visible: opens it instantly for keyboard users, and the arrow is an after: border triangle. Each tip is a real role="tooltip" wired with aria-describedby.

How this works

Delay only on the way in. A transition-delay set inside the hover variant applies while entering the hovered state; the resting state has none, so the tip vanishes the moment the pointer leaves:

opacity-0 transition-[opacity,translate]
group-hover:opacity-100 group-hover:delay-300
group-has-focus-visible:opacity-100 group-has-focus-visible:delay-0

Why has-focus-visible. group-focus-within would also open on mouse click; :has(:focus-visible) opens only for keyboard focus.

Make it yours

  • Tips below the toolbar: top-[calc(100%+10px)] and after:bottom-full after:border-b-kbd13-tip.
  • Longer intent delay: group-hover:delay-500.
  • Light tips in light mode: swap the tip tokens' two values.

Gotchas — read before shipping

  • WCAG 1.4.13 asks that tooltips be dismissible without moving focus; add a small Escape handler in production.
  • Tips near the viewport edge can clip — the first button's tip is centred here because the toolbar is centred.
  • pointer-events-none on the tip keeps it from blocking neighbouring buttons while it fades.

Browser support

ChromeSafariFirefoxEdge
123+17.5+128+123+

Tailwind v4's own sheet needs Chrome 111 / Safari 16.4 / Firefox 128 (cascade layers, @property, color-mix()); the light-dark() theme tokens raise the floor to Chrome 123 / Safari 17.5.
