Expanding Pillar Cards

Install

Or by hand, in a Next.js project with shadcn set up. It writes components/pastetaste/expanding-pillar-cards.tsx.

Install the pastetaste component "Expanding Pillar Cards" (expanding-pillar-cards) into this Next.js project and use it.

What it is: A row of tall cards where one is open: hover, focus or tap another and the width moves to it, its icon grows and a paragraph with a link unfolds. Stacks on phones.

Before you place it, ask me (one short message, in my language; "skip" = sensible default): which page and section it goes in, my brand colour (hex), the text, labels or images it should show, and whether I want my logo or my own copy in the demo content. Then:

Steps:
1. If the project has no components.json, run: npx shadcn@latest init -y -d. Then run: npx shadcn@latest add https://pastetaste.com/r/expanding-pillar-cards.json
   (it writes components/pastetaste/expanding-pillar-cards.tsx; install any npm packages it reports).
2. Import it: import { ExpandingPillarCards } from "@/components/pastetaste/expanding-pillar-cards" (check the file for the exact named export).
3. Put it where it fits on the page I name, keep the rest of the page untouched, and pass props for my colours instead of editing the installed file.
4. It does not depend on Tailwind; colours come from CSS variables (--pt-*) or props.
5. It supports prefers-reduced-motion with a still state; do not remove it.

Props (all optional unless the type has no default):
- cards: { title; tags?; text; icon: ReactNode; cta?; href? }[] = [] — The cards. Icon is any element and is enlarged on the open card.
- defaultIndex: number = 1 — Card that starts open.
- corner: string = '/2026' — Small text at the top right of every card.
- height: number = 520 — Row height in px on wide screens.
- accent: string = ink — Colour of the number rule and the arrow disc.

Then run the dev server, check it in the browser at desktop and mobile width, and tell me the page URL.
