API reference

Accessibility

  • Keep the button's visible text meaningful; the animation is decorative and should not be the only indication of the action.
  • The example uses a native shadcn/ui Button, preserving normal button semantics and keyboard interaction.
  • Use sufficient color contrast for the button label and outline independently of the animated beam.
  • Respect reduced-motion preferences in the surrounding application if animated effects are distracting or unsuitable.
