i was having this issue, in development mode, all css have no issue, but when come to Production , the CSS looks like damaged.

because the tailwindcss have been upgrade to 4.0 , so there is one extra file named postcss.config.mjs
and there are some css error need to be imported or add . please prompt v0 to look at it

/** @type {import('postcss-load-config').Config} */
const config = {
plugins: {
'@tailwindcss/postcss': {},
},
}

export default config

@kelvinlai55555555 i gave it this prompt, it updated it and i published it but its still the same. prompt: "My site works in preview but CSS is broken in production. I suspect a Tailwind CSS version mismatch. Please check: 1. What version of Tailwind CSS is in package.json? 2. Does the project have a postcss.config.mjs file? 3. If using Tailwind 4.0, ensure postcss.config.mjs has this exact config: /** @type {import('postcss-load-config').Config} */ const config = { plugins: { '@tailwindcss/postcss': {}, }, } export default config 4. Make sure tailwind.config.js or tailwind.config.ts is properly configured for the Tailwind version being used 5. Verify all Tailwind classes are compatible with the installed version Fix any Tailwind configuration issues causing CSS to break in production."

Hello! This is a common issue with V0 deployments where CSS works in preview but breaks in production.
Here are the specific steps to resolve this:

1. Check Tailwind CSS Configuration
Verify your package.json has consistent Tailwind versions:

{
  "devDependencies": {
    "tailwindcss": "^3.4.0",
    "@tailwindcss/forms": "^0.5.7"
  }
}

2. Update PostCSS Configuration
Ensure your postcss.config.mjs matches your Tailwind version:

@type {import('postcss-load-config').Config}
const config = {
  plugins: {
    tailwindcss: {},
    autoprefixer: {},
  },
}

export default config

3. Verify Tailwind Config File
Check your tailwind.config.js for proper content paths:

@type {import('tailwindcss').Config}
module.exports = {
  content: [
    "./src/**/*.{js,ts,jsx,tsx,mdx}",
    "./app/**/*.{js,ts,jsx,tsx,mdx}",
    "./pages/**/*.{js,ts,jsx,tsx,mdx}",
    "./components/**/*.{js,ts,jsx,tsx,mdx}",
  ],
  theme: {
    extend: {},
  },
  plugins: [],
}

4. CSS Import Order
Ensure your main CSS file imports Tailwind in the correct order:

@tailwind base;
@tailwind components;
@tailwind utilities;

5. Production Build Check
Run these commands to clean and rebuild:

rm -rf .next
npm run build

The key is ensuring consistency between your development environment and production build configuration. Focus on the PostCSS setup and Tailwind version alignment first, as these are the most common culprits for CSS breaking in production deployments.
