A horizontal scrollable navigation menu with an active pill indicator sliding behind the text, shown in a resizable container.

Resizing Tab Bar with Anchor Positioning

demo & code

This is a Resizing Tab Bar with Anchor Positioning. It demonstrates a modern approach to building a horizontally scrollable navigation menu with a sliding “active” indicator. Its function is to provide a highly fluid, decoupled visual highlighter that perfectly tracks the currently selected tab — even when the container is resized or scrolled — without relying on heavy JavaScript coordinate calculations.

demo & code

Scroll-Driven Sticky Text Reveal is a high-end typographic interface. It utilizes modern CSS scroll timelines to synchronize the visual state of a list with the user’s scroll position.

Scroll-Driven Range Slider

demo & code

Inputs are usually dumb components; they report values but rarely visualize them meaningfully. This slider breaks that mold. It uses the cutting-edge Scroll-Driven Animations API to map the “thumb’s” movement directly to the visual output — without a single line of JavaScript logic for the animation. It creates a tactile, liquid connection between the user’s action and the “mixing” of coffee and milk.

demo & code

This Scroll-Linked View Transition Header demonstrates a cinematic UI pattern common in music apps like Spotify. It uses the View Transition API to morph a large album hero section into a compact, sticky navigation bar, but with a twist: the animation progress is scrubbed directly by the user’s scroll position rather than a fixed timer.

Scroll-Driven Image Swapper

demo & code

This Scroll-Driven Image Swapper demonstrates the bleeding edge of web animation. It uses the native CSS Scroll-driven Animations API to create a complex parallax-like effect where two columns of different heights scroll in sync. As you scroll, the images in the shorter column slide and crossfade to match the context of the taller column. Crucially, the code implements a Progressive Enhancement strategy: it checks for native browser support and falls back to GSAP ScrollTrigger for browsers that haven’t implemented the spec yet.
