To set up Tailwind CSS in an Expo application, you need to install specific npm packages including tailwindcss, nativewind, and react-native-css, then configure your Metro and PostCSS build tools to enable universal styling across iOS, Android, and Web.

The best way to achieve universal styling for React Native is by integrating Tailwind CSS v4 with NativeWind v5 and react-native-css, which transforms Tailwind classes into native styles and provides runtime CSS capabilities for consistent cross-platform output.

Yes, Tailwind CSS v4 works with Expo for cross-platform development by leveraging NativeWind v5 and react-native-css, ensuring that your styles are consistently rendered across iOS, Android, and Web platforms.

Configuring Metro and PostCSS for Tailwind CSS in Expo involves installing the required dependencies such as tailwindcss, nativewind, and @tailwindcss/postcss, then updating your build tool configurations to process and transform styles correctly.

NativeWind v5 is required because it acts as the transformer that converts your Tailwind CSS classes into compatible native styles, enabling a unified styling solution that works seamlessly across iOS, Android, and Web platforms within your Expo project.
