If you've ever tried creating pure CSS scroll animations, you probably realized it's way more complicated than it needs to be. 😓 Sure, it can be done, but when working on real projects, is it actually practical?

The Problem with Pure CSS Scroll Animations ❌

1️⃣ Overly Complicated Hacks

  • Pure CSS solutions rely on scroll snapping or keyframes tied to scroll position.
  • These approaches often require a lot of trial and error to get right. 😵‍💫

2️⃣ Lack of Dynamic Position Awareness

  • CSS has no native way to detect element positions relative to the viewport.
  • This means no way to dynamically adjust animations based on where the element is on screen. ❌

3️⃣ Limited Flexibility

  • Want an animation sequence based on different scroll positions? Not happening.
  • Need to trigger animations at precise points? Good luck.

Enter Trig.js – The Better Way ✅

With Trig.js, you get the best of both worlds: the simplicity of CSS with the power of JavaScript-driven scroll animations. 🔥

🎯 How Trig.js Fixes These Issues:

  • Works with CSS variables 👉 Trig.js updates element position data directly into CSS, allowing you to use var(--trig) or var(--trig-reverse) in styles. With the ability to have pixels and degrees to.
  • Fully dynamic 👉 Trig.js updates on scroll, so animations adapt naturally to viewport changes.
  • More flexibility 👉 You can easily create effects like parallax, scaling, rotation, and more without relying on clunky CSS hacks.
