To set up Tailwind CSS v4 in Expo, you need to wire together NativeWind v5, react-native-css, and Tailwind's PostCSS pipeline within your Metro configuration. This enables consistent className-based styling across iOS, Android, and Web.

Yes, Tailwind CSS v4 works with NativeWind v5 for Expo styling by configuring the Metro bundler and integrating react-native-css. This combination allows you to use Tailwind utility classes directly via the className prop in React Native components.

The best way to configure PostCSS for Tailwind v4 in React Native is using the @tailwindcss/postcss plugin alongside react-native-css. This setup bridges Tailwind's CSS-first approach with React Native's rendering engine.

Yes, you can use className for styling across iOS, Android, and Web in Expo by using CSS-wrapped component patterns. The setup provides wrappers for View, Text, ScrollView, Pressable, TextInput, Image, and Animated to ensure consistent styling.

You need react-native-css to make Tailwind's CSS-first runtime usable within React Native components. It translates CSS rules generated by Tailwind into a format that React Native can apply to elements via the useCssElement wrapper.

A key limitation is that Tailwind CSS v4 with NativeWind v5 requires strict dependency installation and specific Metro configuration. Without correctly wiring react-native-css and PostCSS, className-based styling will not render reliably across platforms.
