Snowfall Animation
Snowfall Animation is a client-side React background component that renders softly falling snow particles behind arbitrary child content. It automatically adapts snowflake colors to the active light or dark theme and resizes with its container.

Usage
usage.tsx
import Snowfall from "@/components/snowfall-animation/snowfall";export default function Example() { return ( <Snowfall className="flex min-h-64 items-center justify-center"> <div className="z-10 text-center"> <h1 className="text-3xl font-bold">Winter Collection</h1> <p>Explore the season.</p> </div> </Snowfall> );}- Add a calm winter atmosphere to hero sections, landing-page headers, or promotional banners.
- Use behind centered calls to action, headings, or other foreground content that should remain interactive.
- Pair with seasonal campaigns, holiday pages, winter events, or decorative empty states.
- Use when a lightweight canvas-based particle background is preferred over static imagery.
Examples
Hero section
A themed hero with custom particle count and speed.
hero-section.tsx
import Snowfall from "@/components/snowfall-animation/snowfall";export default function WinterHero() { return ( <Snowfall count={140} minRadius={1} maxRadius={3} minSpeed={0.4} maxSpeed={1.5} className="flex min-h-96 items-center justify-center rounded-xl" > <div className="z-10 max-w-lg space-y-4 text-center"> <h1 className="text-4xl font-bold">A Quiet Winter</h1> <p>Discover peaceful moments for the season.</p> </div> </Snowfall> );}Call-to-action banner
A compact banner with stronger horizontal movement and an interactive button.
call-to-action-banner.tsx
import { Button } from "@/components/ui/button";import Snowfall from "@/components/snowfall-animation/snowfall";export default function SeasonalBanner() { return ( <Snowfall wind={1} className="flex min-h-56 items-center justify-center rounded-lg" > <div className="z-10 space-y-3 text-center"> <h2 className="text-2xl font-semibold">Seasonal Offers</h2> <Button>Shop now</Button> </div> </Snowfall> );}Dark themed panel
A dark panel that uses the component's theme-aware white snowflakes.
dark-themed-panel.tsx
import Snowfall from "@/components/snowfall-animation/snowfall";export default function DarkWinterPanel() { return ( <Snowfall className="flex min-h-72 items-center justify-center rounded-2xl bg-slate-950"> <div className="z-10 text-center text-white"> <p className="text-sm uppercase tracking-[0.3em]">December</p> <h2 className="mt-2 text-3xl font-semibold">Nightfall</h2> </div> </Snowfall> );}Decorative content section
A larger section using denser, slower particles behind content.
decorative-content-section.tsx
import Snowfall from "@/components/snowfall-animation/snowfall";export default function WinterMessage() { return ( <Snowfall count={180} maxRadius={5} minSpeed={0.25} maxSpeed={1} className="flex min-h-80 items-center justify-center" > <article className="z-10 max-w-md space-y-3 text-center"> <h2 className="text-3xl font-bold">Made for the Quiet Season</h2> <p>Bring a serene winter feeling to your next experience.</p> </article> </Snowfall> );}API reference
PropTypeDefaultDescription
childrenReact.ReactNode—Required content rendered above the snowfall canvas.
countnumber100Maximum number of snowflakes to initialize. The actual count is additionally limited by the container area.
minRadiusnumber1Minimum snowflake radius in canvas pixels.
maxRadiusnumber4Maximum snowflake radius in canvas pixels.
minSpeednumber0.5Minimum vertical snowflake speed per animation frame.
maxSpeednumber2Maximum vertical snowflake speed per animation frame.
windnumber0.5Controls the strength of horizontal wind movement applied to snowflakes.
classNamestring""Additional class names applied to the outer container and the canvas element.
Accessibility
- The canvas is marked with pointer-events-none, so it does not block interaction with links, buttons, or other child content.
- The component does not provide an aria-label or text alternative because the snowfall is decorative; keep meaningful information in the child content.
- Use semantic headings, landmarks, and accessible controls inside the component as usual.
- The source does not implement prefers-reduced-motion handling, so add an external reduced-motion strategy if continuous animation is unsuitable for your users.
