Measured entry

cultui-bg-animated-gradient

background-effectaurora-meshmotion on file

A client-side React background layer that animates between radial-gradient definitions. It ships as a shadcn registry TypeScript component, renders an absolutely positioned Motion div, and depends on the motion package plus utility classes for sizing and placement.

Verdict

A focused, working decorative background with a small API and no provider requirement. It is a sensible fit when Motion is already present, but the missing reduced-motion handling and narrow-screen demo overflow deserve fixes before production use.

Use it if

  • You need a configurable ambient gradient behind hero or feature content.
  • Your React app already uses Motion and can supply gradient stops and animation timing.
  • You can place it inside a positioned, clipped container with foreground content layered above it.

Skip it if

  • You need reduced-motion behavior without modifying the component.
  • You want a CSS-only background and do not want to add Motion for a decorative effect.
  • Your layout cannot guarantee a positioned parent with explicit dimensions and clipping.
  • You need the supplied fixed-width demo to fit narrow screens without responsive changes.

Install the motion package, copy the client component, and ensure your build supports the utility classes it uses or replace them with equivalent CSS. Render it inside a relatively positioned container with defined dimensions and hidden overflow, then layer content above it.
