Frame Expand

Install

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

Install the pastetaste component "Frame Expand" (frame-expand) into this Next.js project and use it.

What it is: Media grows from a small centred card to full-bleed as you scroll, then holds pinned while a caption fades in. The reveal-the-frame beat for product pages.

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/frame-expand.json
   (it writes components/pastetaste/frame-expand.tsx; install any npm packages it reports: motion@^12.23.0).
2. Import it: import { FrameExpand } from "@/components/pastetaste/frame-expand" (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):
- children: ReactNode — The media; fill the frame with it.
- caption: ReactNode — Content that fades in over the bottom of the expanded frame.
- from: number = 0.42 — Starting width as a share of the viewport, 0 to 1.
- radius: number = 24 — Starting corner radius in px.
- height: string = '220vh' — Total scroll length of the section.
- className: string — Extra classes on the section.
- style: CSSProperties — Inline style overrides on the section.

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