Measured entry

cultui-bg-animate-button

hover-effectgradient-glowmotion on file

A React and TypeScript call-to-action button distributed as a shadcn registry file. It creates a rotating or pulsing conic-gradient layer with Tailwind classes, supports Radix Slot composition, and relies on class-variance-authority plus a shadcn-style cn helper backed by clsx and tailwind-merge.

Verdict

A credible fit for prominent calls to action in an existing Tailwind component system, with clean harness behavior. It needs a shadcn-style setup and does not mount bare because its Radix Slot import and supporting conventions are not supplied automatically.

Use it if

  • You need an animated gradient call-to-action that can be tuned through size, rounding, shadow, gradient, and animation props.
  • Your app already uses Tailwind and shadcn conventions, including the cn utility and path alias.
  • You need to render the styling through another element using the asChild composition pattern.

Skip it if

  • Your project does not use Tailwind or you want a self-contained button with no utility-framework setup.
  • You require built-in reduced-motion behavior for continuous decorative animation.
  • You expect every exposed option to work, since variant and showBackground currently do not change the output.

In a non-shadcn project, add Radix Slot and class-variance-authority, provide a cn helper using clsx and tailwind-merge, configure the source path alias or replace that import, and ensure Tailwind scans the component and supports its arbitrary gradient and animation classes. Add a reduced-motion treatment if your accessibility policy requires one.
