Tailwind CSS Classes Not Applying - Styles Ignored
Tailwind CSS classes aren't being applied to elements. You add classes like 'bg-blue-500' but the element stays unstyled.
Sometimes works in some components but not others. Manual styles work fine.
Error Messages You Might See
Tailwind CSS not found
Styles not applying
Class text-blue-500 not recognized
PostCSS plugin error
Common Causes
- Tailwind not configured in tailwind.config.js or config missing CSS input path
- CSS file not imported in main layout or root component
- Dynamic class names (string templates) not scanned by Tailwind content config
- CSS Autoprefixer or PostCSS not configured properly
- Purged classes - content config doesn't include template files with classes
How to Fix It
Verify tailwind.config.js content includes all template paths: content: ['./src/**/*.{js,jsx,ts,tsx}']
Ensure CSS imported in root: import 'tailwindcss/tailwind.css'
Avoid dynamic class names: const className = `text-${color}` won't work. Use full class names or Tailwind merge utility
Check PostCSS config has Tailwind plugin
Rebuild after config changes: npm run dev

Get HelpFrequently Asked Questions
Why don't dynamic Tailwind classes work?
Tailwind uses static analysis. text-${color} is a template and Tailwind can't scan it. Use full class names or mapping
How do I use arbitrary values instead?
Use bracket syntax: bg-[#1234567] for custom colors, or configure in tailwind.config.js
Should I use CSS modules with Tailwind?
Tailwind works best without CSS modules. Use utility-first directly in JSX
