Tailwind Vintage Calculator Key Button
A 1974 desk calculator key: warm beige ABS with a dished top, a chamfered skirt, tight 3px travel, and the orange function key beside it. The dish is two counter-facing radial gradients, and the press collapses a hard shadow stack so it lands with a stop.

Which parts became utilities, which stayed CSS, and why.
- Utilities: both keys in full — the six-segment rest shadow, the collapsed press shadow, the 3px travel, the printed legend, the focus ring, the disabled state. CSS: the two dish recipes and the panel.
- The accent key differs from the base key by four classes (ink colour, text-shadow, and two shadow stacks) plus one background rule. That ratio — a variant as a handful of overrides on a repeated base — is the same shape as the primary/secondary pair in demo 02, sixteen hundred lines earlier.
- Third demo in the collection where travel and shadow depth must be the same number (after the concrete slab and the typewriter key), and the third time utilities put them on one line. It is the strongest recurring argument for this port.
- A11y fix from the CSS original: the accent was
oklch(0.62 0.17 43)with--accent-ink:#fff3e6— about 3.2:1, well under the minimum for a 15px legend. The port darkens the accent key to0.56(≈4.6:1) and keeps the same orange family, so the 1974 palette survives a contrast check.

Demo: Tailwind Vintage Calculator Key Button
Source: https://codefronts.com/components/tailwind-css-buttons/tailwind-vintage-calculator-key-button/
A 1974 desk calculator key: warm beige ABS with a dished top, a chamfered skirt, tight 3px travel, and the orange function key beside it. The dish is two counter-facing radial gradients, and the press collapses a hard shadow stack so it lands with a stop.

```How this works
A dished keycap is the inverse of a domed one. Dark at the top, light at the bottom — get it backwards and you have a 2010s app button:
radial-gradient(120% 100% at 50% -18%, rgba(0,0,0,.15), transparent 58%),
radial-gradient(120% 90% at 50% 118%, rgba(255,255,255,.6), transparent 56%),
linear-gradient(180deg, var(--cap-lo), var(--cap))It stays in CSS for the same reason as the typewriter key: the dish must invert rather than darken in dark mode, which is a rule about the recipe, not a value.
Travel and skirt must match. Three 1px segments, 3px of travel — the same arithmetic as the concrete slab and the typewriter key, and the third time the collection makes the point that utilities put the two numbers next to each other.
Make it yours
--color-tb47-cap/-skirt: warm beige, chocolate brown and safety orange are the period palette.- Travel and shadow depth move together — 2px is a laptop key, 4px a cash register.
col-span-2on the accent key makes an equals bar.- A condensed grotesque legend reads more 1980s than 1970s.
- The pad is a normal flex row — add a third key without touching either key's classes.
Gotchas — read before shipping
- Two keys in a row need identical heights. Set
min-h-*rather than relying on the line-box. - Dished gradients look wrong on dark themes. Invert the two radial stops; don't just darken the cap.
- Hard shadow travel exposes subpixel rounding. Whole-pixel offsets.
- Keys imply a keypad. If they don't type, keep the labels verbs.
- Never remove the focus ring on a key-styled control — the press state is not a focus state.
