# FourthBentoAnimation

> A scheduling vignette for the bento grid: a week ruler, three task bars that spring into place, and a time cursor that follows the pointer.

## Facts

- **Product**: Crew OS
- **Family**: Motion
- **Global**: `window.DigitalCrew.FourthBentoAnimation`
- **Source**: `digitalcrew-orchestrator: components/fourth-bento-animation.tsx`
- **Import in the app**: `import { FourthBentoAnimation } from "@/components/fourth-bento-animation";`
- **Live preview**: /design/components/fourth-bento-animation/preview.html
- **Page**: /design/components/fourth-bento-animation

## Guidelines

**Use it for** the "Smart automation" tile of [`BentoSection`](/design/components/bento-section.md). The labels ("Bento grid", "Landing Page", "Add Task", "Tue"–"Sat", "12:00 AM") are fixed demo copy.

**What you provide**: `once` (default false: bars fly out again when it leaves the viewport) and `startAnimationDelay` (s, default 0). Give the parent a height and `isolate` (the ruler sits at `-z-10`).

**Anatomy**: a dashed ruler of half-width columns with 20px `bg-primary` ticks, masked to fade at top and bottom; day labels in `text-sm text-gray-500`. The cursor is a 2px line from `black` (`dark:` `accent`) to transparent, with a 24px-tall black (`dark:bg-accent`) time label, `text-xs`, `rounded-md`. Bars are 250px wide, 32px tall, `rounded-lg`, `text-sm font-medium`: `bg-secondary text-white` (`dark:bg-neutral-700`), `bg-secondary/40 text-white` (`dark:bg-neutral-800`) and a dashed `bg-secondary/20` outline bar. With Crew OS's light `secondary` the white labels are low-contrast in light themes.

**Behaviour**: in view, bars slide from alternate sides into a staircase with a spring (stiffness 220, damping 18), 0.2s apart. Moving the pointer drives the cursor through a spring (damping 50, stiffness 400); leaving recentres it. No reduced-motion branch.

**Don't** use it as a real timeline: nothing is data-driven.

## API

```ts
interface FourthBentoAnimationProps {
    startAnimationDelay?: number;
    once?: boolean;
}
export declare function FourthBentoAnimation({ once, startAnimationDelay, }: FourthBentoAnimationProps): JSX.Element;
```

## Example

```html
<div id="root" class="p-6"></div>
<script>
(function () {
  var h = React.createElement, DC = window.DigitalCrew, I = DC.Icons;
  function App() {
    return h("div", { className: "relative isolate h-[340px] overflow-hidden rounded-xl border" }, h(DC.FourthBentoAnimation, { once: false }));
  }
  ReactDOM.createRoot(document.getElementById("root")).render(h(DC.TooltipProvider, { delayDuration: 80 }, h(App)));
})();
</script>
```

- [CardResize](/design/components/card-resize.md): A container that tweens its width and height when its content changes (`.t-resize`).
- [ChapterScrubber](/design/components/chapter-scrubber.md): A rail of ticks, one per chapter, that swell like a dock under the pointer, with a card previewing the hovered chapter.
- [ContainerScroll](/design/components/container-scroll.md): A hero block where a device-like frame starts tilted back in 3D and straightens as the page scrolls, with the title drifting up.
- [FeatureSlideshow](/design/components/feature-slideshow.md): A step-by-step feature explainer: an accordion of steps on the left that advances on a timer, a progress line on the open step, and a large media slot on the right.
- [FirstBentoAnimation](/design/components/first-bento-animation.md): A self-playing chat vignette for the bento grid: a user asks for a meeting slot, the Digital Crew avatar shows typing dots, then the reply streams in as a `Reasoning` block.
- [HyperText](/design/components/hyper-text.md): A monospaced, uppercase text effect: letters scramble through random characters, then lock in from left to right.
- [InfiniteSlider](/design/components/infinite-slider.md): A JavaScript-driven endless strip (Framer Motion) that renders its children twice and slides them in a loop, optionally slowing on hover.
- [JoyfulTaskCheckbox](/design/components/joyful-task-checkbox.md): A task checkbox with a small, restrained completion moment: one soft bloom, two sparks, then stillness.
- [Lottie](/design/components/lottie.md): The lottie-react player, exported as-is, for the Lottie animations that ship with Crew OS (`animations/*.json`).
- [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.
- [SkeletonReveal](/design/components/skeleton-reveal.md): A skeleton that cross-blurs into the loaded content, so the swap reads as one motion (`.t-skel`).
- [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.
