Measured entry

animata-scroll-reveal

scroll-effectspatialmotion on file

A React text treatment shipped as a shadcn registry TSX component. It creates its own scrollable panel, splits plain text into fragments, and maps panel scroll progress to per-fragment opacity with Motion. Its styling assumes Tailwind theme utilities plus the project cn helper and import alias.

Verdict

A focused effect that builds, mounts, stays within its viewports, and shows no detected accessibility violations in the configured demo. It is best for short, deliberate story beats. It needs a shadcn-style setup and is less suitable as a drop-in for lean or page-scroll-driven sites.

Use it if

  • You want copy to brighten progressively as the reader scrolls inside a bounded story panel.
  • Your React app already uses Motion, Tailwind theme utilities, and the standard cn helper.
  • The content is mostly plain text or simple inline elements that can be revealed as fragments.

Skip it if

  • The reveal must follow the page scroll instead of a nested scrolling region.
  • You need rich nested markup to reveal word by word, because nested elements are treated as single fragments.
  • You are minimizing client-side bundle growth for a single decorative text effect.
  • Your design cannot accommodate the component's generated vertical spacer content and fixed-height panel.

Providerno provider required in the harness

In a non-shadcn project, add React and Motion, configure Tailwind with the foreground and background theme utilities used here, provide a class-merging cn helper, and either configure the at-sign source alias or replace that import with a local path. Ensure the component runs on the client in frameworks that separate server and client modules.
