A snow effect without a library
Snow is a set of small, blurred dots falling at slightly different speeds — smaller flakes fall slower, which adds depth — while each sways gently side to side. Everything runs on CSS animations of transform, so it stays smooth and light. The overlay uses pointer-events: none so links and buttons keep working.
More effects — rain, shooting stars, confetti, your own SVG — are in the Particle Animation Generator.

Frequently asked questions
How do I add snow to my website for Christmas?
Copy the HTML + CSS here and paste it just before the closing body tag, or into a Custom HTML / Embed block in WordPress, Webflow or Shopify. Remove it after the season.
Will the snow block clicks?
No. The overlay uses pointer-events: none, so visitors can click everything under it.
Can I make it snow only in the header?
Yes — choose One section, paste the code inside your header and give the header position: relative.
Can I install CSS Snow Effect as a web app and use it offline?
Yes. CSS Snow Effect is an installable web app (PWA) — installed from your browser, not downloaded from an app store. Click Install app at the top of this page in Chrome or Edge (Windows, macOS, Linux, ChromeOS) or on Android, use Share → Add to Home Screen on iPhone and iPad, or File → Add to Dock in Safari 17+ on a Mac. It then opens in its own window with its own icon, and because it runs entirely in your browser it keeps working offline. Firefox on desktop can’t install web apps. How installing works.
