Full-screen hero section displaying a vivid blue-to-orange conic gradient background using OKLCH color space with centered white typography

Vibrant OKLCH Conic Hero

For too long, the web has been trapped in the dull, muddy spectrum of sRGB. We accept “gray dead zones” in our gradients as a fact of life. No more. This hero section embraces the OKLCH color space to deliver vibrance that matches the human eye’s perception. It is not just a background; it is a radiant, high-definition light source that bathes your typography in pure energy. (Requires: open-props)

Dark background with white typography, featuring a highlighted phrase with a moving purple-pink gradient and animated four-point stars

Sparkling Gradient Text Highlight

Typography on the web often suffers from a lack of vitality. We treat words as static information, ignoring their potential to convey wonder. This component injects a sense of “magic” into the reading experience. By combining a kinetic gradient with a randomized particle system, we create a focal point that breathes. It is not just a highlight; it is a celebration of the message, designed to captivate the user’s peripheral vision without overwhelming the content.

Split-screen interface where the left column images slide and crossfade in sync with the scrolling right column, featuring progress indicators.

Scroll-Driven Image Swapper

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.

The result is a set of distinct, scalable inputs that rely on a single HTML <input> tag without any wrapper divs.
