Smooth Scrolling & Animations with GSAP + Lenis - Scroll Faster, Animation Faster — Velocity Text Effects

In this tutorial I am building a scroll velocity marquee from scratch — four infinite rows that physically react to your scroll speed using GSAP ScrollTrigger. Scroll slow and the rows drift. Scroll fast and they accelerate. Stop scrolling and they ease back down like they have weight. This is not a CSS marquee. This is a data-driven, GPU-accelerated, velocity-reactive animation system. This video showcases diverse web development concepts, emphasizing dynamic scrolling animation and intricate timeline animation techniques. We explore how to integrate these elements to create captivating website animations. Dive into the world of motion design and see how these tools bring web projects to life.
