Theming

LuckyUI provides a comprehensive theming system using CSS variables:

// In your layout.tsx
import { ThemeProvider } from "@/components/theme-provider";

export default function RootLayout({ children }) {
  return (
    <html lang="en" suppressHydrationWarning>
      <body>
        <ThemeProvider
          attribute="class"
          defaultTheme="system"
          enableSystem
        >
          {children}
        </ThemeProvider>
      </body>
    </html>
  );
}

Customizing Theme Colors

  --secondary: 240 4.8% 95.9%;
  --background: 0 0% 100%;
  --foreground: 240 10% 3.9%;
  /* ... more variables */
}

.dark {
