Measured entry

uilayouts-3d-marquee

hero-effect3dmotion on file

A client-side React showcase that tilts a vertically looping image marquee to create a faux depth effect. It ships through a shadcn registry as a display component plus a reusable marquee helper, with hardcoded remote images. It depends on Tailwind utility and animation styles, an alias-based import path, and a local class-merging utility.

What the harness recorded

BARE BUILD

✗ Build failed in 30.85s
error during build:
[vite:load-fallback] Could not load <sandbox>/src/lib/utils (imported by src/components/ui/marquee.tsx): ENOENT: no such file or directory, open '<sandbox>/src/lib/utils'

Verdict

A convincing decorative effect for an existing design-system project, but it is more demo than reusable component because its images and layout are fixed. It builds and mounts in the prepared harness, while a bare project fails on the missing utility import. It needs a shadcn-style setup and responsive cleanup before production use.

Use it if

  • You need a decorative portfolio or campaign visual with continuous vertical motion.
  • Your app already follows shadcn-style file aliases and Tailwind conventions.
  • You are comfortable replacing the hardcoded image list directly in the component.

Skip it if

  • You need a drop-in component for a plain React project.
  • Your content must be supplied through props or managed by a CMS without modifying source.
  • Horizontal overflow on narrow screens is unacceptable without additional responsive work.
  • You need motion controls or reduced-motion behavior out of the box.

Bare installfails once the shadcn-style helpers are removed, so it needs that setup
Providerno provider required in the harness

In a non-shadcn project, add the alias used by the imports, provide a compatible class-merging utility, copy both the display and marquee files, and supply the Tailwind utilities and marquee keyframes referenced by their classes. Configure remote image loading as needed, replace the sample URLs, and add narrow-screen overflow and reduced-motion handling.
