This collection explores modern JavaScript techniques for implementing infinite scroll, with a strong emphasis on the Intersection Observer API for high-performance viewport detection. This approach avoids the performance pitfalls of traditional scroll event listeners, ensuring a smooth user experience even on content-heavy pages. You’ll see practical examples of asynchronously fetching data using the Fetch API and dynamically appending new content to the DOM.
8 Javascript Infinite Scroll Examples
3D Rotating iOS Time Picker
demo & codeThis 3D Rotating iOS Time Picker recreates the tactile feel of native mobile controls on the web. It features three independently rotating wheels (Hours, Minutes, Meridiem) that snap into place with satisfying physics. The component leverages the cutting-edge Scroll-driven Animations API for buttery-smooth performance on supported browsers, while seamlessly falling back to GSAP for others. The 3D perspective creates a “drum” effect where numbers fade and rotate away as they leave the center view.
Draggable 3D Parallax Image Ring
demo & codeThis Draggable 3D Parallax Image Ring creates a high-end, immersive gallery experience often associated with WebGL, but built entirely with DOM elements and GSAP. It arranges images in a 3D circle that users can spin with a swipe or mouse drag. The standout feature is the calculated parallax effect: as the ring rotates, the background position of each image shifts in the opposite direction, creating a convincing illusion of depth and window-like transparency.
Let's Move! GSAP Infinite Horizontal Scroll
An infinite 3D card carousel powered by GSAP ScrollTrigger.

Image Gallery with GSAP Observer Plugin
A seamless image slider featuring an infinite-scroll SVG navigation menu powered by GSAP’s Observer plugin. The interaction logic translates scroll and swipe deltas into timeline progress, utilizing complex snapping algorithms and opacity tweens to create a fluid, kinetic browsing experience that dynamically updates the active index.
See the Pen Image Gallery with GSAP Observer Plugin.
Infinite Cover Flow with GSAP and Tailwind
Experience a sophisticated “pinned” scrolling effect where a vertical scroll action drives a horizontal card carousel. GSAP’s pin: '.gallery' property freezes the component in the viewport, while ScrollTrigger’s onUpdate callback scrubs a GSAP timeline to animate the cards’ xPercent, scale, and opacity.

Infinite Scrolling with Image Cards
This infinitely scrolling image grid employs an IntersectionObserver with baton-passing observation to dynamically load content from the Pixabay API, creating cards through DOM manipulation as the user scrolls. JavaScript manages the paginated requests while CSS Grid provides responsive layout adaptation, with custom properties enabling seamless dark/light theme switching and clip-path animations.
See the Pen Infinite Scrolling with Image Cards.
Infinite Scrolling Cards with GSAP and ScrollTrigger
A demonstration of an advanced GSAP technique for an infinite carousel, where the animation of each element is cyclically repeated with precise staggering, creating the feeling of continuous 3D space.

Bootstrap 5 Carousel with Multiple Items
A robust infinite carousel implementing a cloning strategy for seamless looping and complex touch/mouse drag logic for native-like swiping.
