# SkeletonReveal

> A skeleton that cross-blurs into the loaded content, so the swap reads as one motion (`.t-skel`).

## Facts

- **Product**: Crew OS and Max
- **Family**: Motion
- **Kind**: Showcase page (tokens and patterns)
- **Source**: `: app/transitions.css`
- **Live preview**: /design/components/skeleton-reveal/preview.html
- **Page**: /design/components/skeleton-reveal

## Guidelines

**What you provide**: a `.t-skel` wrapper with a fixed height holding `.t-skel-skeleton` (add `is-pulsing` to pulse its children) and `.t-skel-content`; add `is-revealed` when data arrives. To replay, add `is-resetting`, force a reflow, then remove it.

**Timing**: 400ms (`--reveal-dur`), `ease-in-out`, 2px blur (`--reveal-blur`); the pulse is 1s to 50% opacity. Reduced motion swaps instantly.

**Use it for** records and cards whose shape is known before the data. Shape the skeleton like the content.

## Example

```html
<div id="root" class="p-6"></div>
<script>
(function () {
  var h = React.createElement, DC = window.DigitalCrew, I = DC.Icons;
function App() {
  var s = React.useState(false), r = React.useState(false), ref = React.useRef(null);
  function replay() { r[1](true); s[1](false); requestAnimationFrame(function () { if (ref.current) void ref.current.offsetWidth; r[1](false); setTimeout(function () { s[1](true); }, 900); }); }
  React.useEffect(function () { var t = setTimeout(function () { s[1](true); }, 900); return function () { clearTimeout(t); }; }, []);
  return h("div", { className: "grid gap-3" },
    h("div", { ref: ref, className: "t-skel h-20 max-w-md" + (s[0] ? " is-revealed" : "") + (r[0] ? " is-resetting" : "") },
      h("div", { className: "t-skel-skeleton is-pulsing flex items-center gap-3" },
        h("div", { className: "size-12 rounded-full bg-accent" }),
        h("div", { className: "grid flex-1 gap-2" }, h("div", { className: "h-4 w-2/3 rounded bg-accent" }), h("div", { className: "h-4 w-1/2 rounded bg-accent" }))),
      h("div", { className: "t-skel-content flex items-center gap-3" },
        h(DC.ProspectAvatar, { name: "Claire Dubois", size: "md" }),
        h("div", { className: "grid" }, h("span", { className: "font-medium" }, "Claire Dubois"), h("span", { className: "text-sm text-muted-foreground" }, "CFO · Northwind Traders · Paris")))),
    h(DC.Button, { size: "sm", variant: "outline", className: "w-fit", onClick: replay }, "Replay"));
}
  ReactDOM.createRoot(document.getElementById("root")).render(h(DC.TooltipProvider, { delayDuration: 80 }, h(App)));
})();
</script>

- [Marquee](/design/components/marquee.md): An endless CSS scroll of repeated content, horizontal or vertical, speed set with two CSS variables.
- [MotionScale](/design/components/motion-scale.md): The shared motion scale made visible: the same distance travelled on each duration token and each easing, with a Replay button.
- [NumberFlowCounter](/design/components/number-flow-counter.md): A small dark pill that shows one number at a time and rolls its digits to the next value every two seconds (NumberFlow).
- [OrbitingCircles](/design/components/orbiting-circles.md): Places its children on a circular orbit around the centre of the parent and spins them, with an optional faint ring for the path.
- [ShimmerText](/design/components/shimmer-text.md): A status line with a light band sweeping across its glyphs — Max's "Thinking…" and live tool lines (`.t-shimmer`).
- [SignatureGradient](/design/components/signature-gradient.md): The signature Digital Crew gradient — indigo → pink → amber (`dc-andre`, `dc-camille`, `dc-amber`) — in its four forms.
- [StreamingText](/design/components/streaming-text.md): Streamed words resolving through a soft cross-blur, one after another (`.t-stream-w` → `.is-in`).
- [ThirdBentoAnimation](/design/components/third-bento-animation.md): An insight vignette for the bento grid: a smooth area line draws itself, a dot pulses at its midpoint and a dark pill above it ticks through values.
- [UniboxMotion](/design/components/unibox-motion.md): The Unibox's shared motion vocabulary: every surface moves on the same few springs, so the whole inbox feels like one physical material.
