Installation

  1. 1. Install the dependencies.

    terminal
    npm install gsap clsx tailwind-merge
  2. 2. Add the cn helper, if you don't already have it.

    lib/utils.ts
    import { clsx, type ClassValue } from "clsx";
    import { twMerge } from "tailwind-merge";
    
    export function cn(...inputs: ClassValue[]) {
      return twMerge(clsx(inputs));
    }
  3. 3. Copy the component into your project.

    /* ── Scroll choreography for everything below the hero. ────────────────────
       Two engines, deliberately kept apart:
    
       1. One-shot entrances, driven by IntersectionObserver. Each element picks
          its move with data-anim; data-delay and data-stagger tune it.
       2. Scroll-linked drift, driven by a rAF loop reading getBoundingClientRect.
    
       Neither uses ScrollTrigger, and that is on purpose. The hero pins itself
       across ~2.8 viewports and Work is pulled up over it by a negative margin,
       so the page geometry ScrollTrigger resolves its start/end against moves
       underneath it. A one-shot reveal whose start ends up unreachable strands
       its element at autoAlpha 0 — invisible for good. getBoundingClientRect is
       measured live against the viewport, so it cannot go stale the same way.
    
       Parallax writes the standalone CSS `translate` property rather than
       `transform`, so it composes with (instead of clobbering) the transform an
       entrance tween leaves behind on the same element. Same trick the resting
       card tilts use with `rotate`. */
