# Carousel Navigator

> Dynamic carousel navigator with theme-adaptive transitions

A Carousel component for React, Tailwind and shadcn by @watermeloncorp, version 1.0.0, MIT licence.

Renders a carousel navigator with theme-adaptive background transitions and progress-syncing indicators. It shows navigation buttons and dots that change based on the current slide. It updates the background and indicators dynamically as the slide changes. Use it for interactive, theme-aware carousels.

## Install

```bash
npx layro-cli add @watermeloncorp/carousel-navigator
```

Or with shadcn: `npx shadcn@latest add https://layro.dev/r/watermeloncorp/carousel-navigator.json`
