Measured entry
ruixen-scroll-burn-text
scroll-effectunclassifiedmotion on file
A client-side React and Tailwind scroll narrative that scales layered text toward the reader, burns it away glyph by glyph, adds a color split and grain, then reveals the next section. It ships as a shadcn registry item and uses browser scroll and resize APIs rather than an animation library. It depends on the project cn utility, clsx, tailwind-merge, and shadcn-style theme classes.

What the harness recorded
BARE BUILD
✗ Build failed in 1.01s error during build: [vite:load-fallback] Could not load <sandbox>re-2185bcf933a2/src/lib/utils (imported by src/cut/components/ruixen/scroll-burn-text.tsx): ENOENT: no such file or directory, open '<sandbox>re-2185bcf933a2/src/lib/utils'
Verdict
A distinctive fit for a short manifesto or campaign interlude, with sensible reduced-motion handling and no external motion package. It needs a shadcn-style setup to mount, and teams should fix keyboard access for the scrollable region before shipping the bounded-panel version.
Use it if
- You need a full-screen editorial passage where scrolling controls a fixed sequence of text sections.
- You want a cinematic burn and depth effect without adding a dedicated animation library.
- Your design can accommodate a dominant, motion-led section with a plain reduced-motion reading mode.
Skip it if
- You need dense copy, links, controls, or selectable content inside the animated sections.
- Your page cannot afford hundreds of per-glyph elements and scroll-driven style updates.
- You need the supplied bounded scroll region to be keyboard-ready without accessibility work.
- Your visual system does not use Tailwind or shadcn-style background, foreground, and muted tokens.
Install
| Declared dependencies | clsx, tailwind-merge |
|---|---|
| Missing on install | none |
| Bare install | fails once the shadcn-style helpers are removed, so it needs that setup |
| Provider | no provider required in the harness |
In a non-shadcn project, add Tailwind with background, foreground, and muted foreground theme classes; provide the aliased cn helper at the expected lib path using clsx and tailwind-merge; preserve the client-component boundary; and make any custom scroll container focusable and clearly labeled.
