# Tilt Card

> Tilt Card with 3D effect

A Card component for React, Tailwind and shadcn by @educlopez, version 1.0.1, MIT licence.

A card component that tilts and scales when hovered or focused, creating a 3D effect. It responds to mouse movement and keyboard focus, adding depth and interactivity. It can include a glare effect and parallax elements. Use it to enhance visual engagement in a product or content display.

## Install

```bash
npx layro-cli add @educlopez/tilt-card
```

Or with shadcn: `npx shadcn@latest add https://layro.dev/r/educlopez/tilt-card.json`

npm packages: motion
