Measured entry

tripled-bottom-modal

dialogglassmorphismmotion on file

A client-side React bottom modal that slides over a blurred backdrop and includes focus trapping, Escape dismissal, scroll locking, focus restoration, and reduced-motion handling. It ships as registry source and relies on Framer Motion, Lucide icons, Tailwind theme classes, and a shadcn Button import.

Verdict

A sound, accessible starting point for a focused bottom confirmation modal, with clean responsive behavior in the harness. It is demo-shaped rather than reusable as shipped, and it needs a shadcn-style setup before it can build or mount in a bare React project.

Use it if

  • You want a compact confirmation or welcome dialog anchored to the bottom edge.
  • Your app already uses shadcn conventions, Tailwind theme tokens, and Framer Motion.
  • You prefer an inspectable modal implementation with keyboard and focus behavior in the component itself.

Skip it if

  • You need a general-purpose dialog primitive with nested dialogs, portals, or extensive composition APIs.
  • You want to avoid the runtime and bundle cost of Framer Motion for a single transition.
  • Your design system does not provide shadcn-style aliases, Button plumbing, or matching Tailwind tokens.
  • You need the content and actions exposed as props without first refactoring the fixed demo copy.

In a non-shadcn project, add React, Framer Motion, Lucide React, a compatible Button component, the project alias used by the import, and any class-merging utility that Button expects. Also provide Tailwind with the semantic color, border, shadow, backdrop, and focus-ring classes used by the source, or translate those styles to your own system.
