Ever noticed how GitHub’s mobile app keeps the page repo details visible in a floating header as you scroll? It’s a slick UX touch that enhances navigation. In this post, I’ll show you how to achieve the same effect using Trig.js, the lightweight and ultra-fast scroll animation library.
Why Use Trig.js for Scroll Animations?
Most AOS (Animation on Scroll) libraries rely heavily on JavaScript for animations, which can impact performance. Trig.js is different—it’s CSS-based, meaning it leverages the browser’s GPU for smoother, more efficient animations.
✅ Why Trig.js?
⚡ Lightweight (~4KB) → No bloated dependencies
🎯 Optimized for scroll performance → No jank, no lag
🎨 Pure CSS scroll animations → Faster than JS-heavy alternatives
🏆 Best AOS alternative → Simple, powerful, and built for modern web apps
