Tailwind Icon Button Group Toolbar with Tooltips (Rich Text Editor)

A rich-text formatting toolbar: icon buttons with CSS-only tooltips (after:content-[attr(data-tip)]) that also appear on keyboard focus, real toggle state via aria-pressed:, and a sample paragraph that previews bold, italic and underline as you press them. A short controller adds toolbar arrow-key navigation and the toggles themselves.

What changed in the port

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

  • .btn-07__tool::after{content:attr(data-tip)…} became after:content-[attr(data-tip)] plus positioning utilities; the arrow is a before: border triangle.
  • [aria-pressed=true] became the built-in aria-pressed: variant.
  • UI upgrade: the toggles actually toggle now (the original only drew a pressed state), Clear resets them, and a sample paragraph previews the formatting live.
  • UI upgrade: tooltips show keyboard shortcuts, the toolbar is one Tab stop with arrow/Home/End navigation, and muted icons reach 7:1 on the bar.

          b.setAttribute('aria-pressed', String(b.getAttribute('aria-pressed') !== 'true'));
        }
      });
      b.addEventListener('keydown', (e) => {
        const n = btns.length;
        const next = { ArrowRight: (i + 1) % n, ArrowLeft: (i - 1 + n) % n, Home: 0, End: n - 1 }[e.key];
        if (next === undefined) return;
        e.preventDefault();
        focusAt(next);
      });
    });
  });
})();
```

How this works

Tooltips from the attribute. Each button carries its label once, in data-tip; two pseudo-elements draw the bubble and its arrow:

<button data-tip="Bold · ⌘B" aria-label="Bold" aria-pressed="true"
  class="after:content-[attr(data-tip)] after:opacity-0
         hover:after:opacity-100 focus-visible:after:opacity-100
         aria-pressed:bg-tbg07-acc">

The preview listens with :has(). The editor card is group/ed; the sample text asks whether a pressed bold button exists and bolds itself. The script only ever flips aria-pressed.

Make it yours

  • Tooltip below: swap after:bottom-[calc(100%+10px)] for after:top-[calc(100%+10px)] and flip the arrow.
  • Add a button: copy one, set data-cmd, data-tip and aria-label; toggles need aria-pressed="false".
  • Light toolbar on dark: tokens --color-tbg07-bar and --color-tbg07-ink.

Gotchas — read before shipping

  • Generated tooltip text is not reliably announced — keep aria-label on every icon button.
  • Action buttons (Link, Clear) must not carry aria-pressed, or they read as toggles.
  • Tooltips are clipped by overflow-hidden ancestors; leave room above the bar.
