A behavioral engine that intercepts user actions (click, hover, visible) on standard DOM elements to trigger custom particle animations, physics-based viewport crossings, or micro-feedback flows using slotted SVGs or markup templates.

A floating circular lens that follows the cursor or touch point, revealing a synchronized secondary image exactly where the user looks. Built for luxury and high-tech product storytelling.

Headline text block that cycles through marketing phrases with a realistic typing and deleting animation. Includes speed variance, simulated auto-correcting typos, and a blinking cursor.

Gate any third-party content behind a consent prompt. The component manages show/hide state only — you provide both the placeholder UI and the content, keeping it composable and unbiased.

Rotates a single word inside a static sentence block with smooth vertical slide or 3D flip transitions. Designed to pull attention to changing value propositions.

Zero-build, ultra-fast bundle regression prevention utility in Rust

Encapsulated side-by-side or inline comparison block for two text or code snippets. Computes a line-level diff internally using LCS and renders color-coded deleted/inserted/unchanged lines with optional line numbers.

Clamps slotted text to an exact line count via a lines attribute. When content overflows, a More/Less toggle appears inline. A ResizeObserver recalculates overflow on every viewport resize so the clamp is always mathematically correct.

Lightweight, accessible scroll progress indicator. Tracks viewport scrolling by default, or can be targeting a specific scrollable element using selectors.
