Comet Card
CometCard is a client-side interactive card wrapper that responds to pointer movement with a 3D tilt, depth translation, hover scale, and animated glare overlay. It accepts arbitrary React content as its children.

Usage
usage.tsx
import { CometCard } from "@/components/ui/comet-card";export function Example() { return ( <CometCard> <div className="rounded-2xl bg-slate-950 p-6 text-white"> <h2 className="text-lg font-semibold">Featured project</h2> <p className="mt-2 text-sm text-slate-300">Explore the latest work.</p> </div> </CometCard> );}- Highlight product cards, profile cards, portfolio items, or featured content with an engaging hover treatment.
- Use for visually rich landing-page sections where pointer-driven depth adds emphasis.
- Wrap existing card content when you want the interaction without prescribing internal layout or styling.
- Avoid using it as the only way to expose important information or actions, since its interaction is pointer-based.
Examples
Product card
A product preview with pricing and an action inside the interactive wrapper.
product-card.tsx
import { CometCard } from "@/components/ui/comet-card";export function ProductCard() { return ( <CometCard rotateDepth={12} translateDepth={14}> <article className="w-72 rounded-2xl bg-white p-5 shadow-xl"> <div className="aspect-square rounded-xl bg-gradient-to-br from-indigo-500 to-fuchsia-500" /> <h2 className="mt-4 font-semibold">Aurora Lamp</h2> <p className="mt-1 text-sm text-muted-foreground">Ambient light for calm spaces.</p> <p className="mt-4 font-medium">$129</p> </article> </CometCard> );}Profile card
A profile presentation with custom tilt and depth values.
profile-card.tsx
import { CometCard } from "@/components/ui/comet-card";export function ProfileCard() { return ( <CometCard rotateDepth={10} translateDepth={10}> <article className="w-80 rounded-2xl bg-zinc-900 p-6 text-white"> <div className="flex items-center gap-4"> <div className="flex size-14 items-center justify-center rounded-full bg-emerald-400 font-bold text-zinc-950">AK</div> <div> <h2 className="font-semibold">Avery Kim</h2> <p className="text-sm text-zinc-400">Product designer</p> </div> </div> <p className="mt-5 text-sm text-zinc-300">Designing clear, useful interfaces for complex products.</p> </article> </CometCard> );}Featured callout
A prominent content callout that preserves semantic heading and link content.
featured-callout.tsx
import { CometCard } from "@/components/ui/comet-card";export function FeaturedCallout() { return ( <CometCard className="max-w-md"> <section className="rounded-2xl bg-gradient-to-br from-cyan-500 to-blue-700 p-8 text-white"> <p className="text-sm font-medium uppercase tracking-wide text-cyan-100">New release</p> <h2 className="mt-2 text-2xl font-bold">Build faster with the new toolkit</h2> <a className="mt-6 inline-block font-medium underline underline-offset-4" href="/docs">Read the documentation</a> </section> </CometCard> );}API reference
PropTypeDefaultDescription
rotateDepthnumber | undefined17.5Controls the maximum rotation depth in degrees for the pointer-driven rotateX and rotateY transforms.
translateDepthnumber | undefined20Controls the maximum pointer-driven translation depth in pixels.
classNamestring | undefinednullAdditional class names applied to the outer wrapper, merged with `perspective-distant transform-3d` using `cn`.
childrenReact.ReactNodenullContent rendered inside the animated card before the glare overlay.
Accessibility
- The component has no built-in semantic element, accessible name, keyboard interaction, focus styling, or click behavior; provide appropriate semantic elements and controls inside `children`.
- Do not communicate essential information through the tilt, scale, shadow, or glare effects alone.
- The interaction is driven by `onMouseMove` and `onMouseLeave`, so it does not provide an equivalent touch or keyboard interaction.
- Keep text and controls inside `children` accessible at rest, and ensure sufficient color contrast against the card background.
- Consider adding an application-level reduced-motion strategy if the surrounding experience must accommodate users who prefer reduced motion; this source does not implement one.
