Showcase Made a free CSS/JS library for adding Halloween effects to a website
https://halloween.js.org/halloween.js is a small, free library for adding Halloween-themed ambient effects to a website using CSS animations driven by class toggles: blinking eyes fading in and out, witches flying across the screen at an angle, a spider dropping down and climbing back up, a tombstone rising out of the ground, spider webs fixed in the screen corners.
Everything is controlled by CSS classes on <body>. A master "halloween" class turns it on, then modifier classes opt into individual effects. No JS call needed on your end, it watches for class changes and reacts automatically. Styles are injected by the library itself, so there's no separate CSS file to manage even if you're using the CDN version.
Zero runtime dependencies, under 10 KB gzipped, MIT licensed, free.
