Hey fellow developers! 👋
Just solved a classic frontend setup puzzle and thought I'd share in case anyone else is wrestling with the same issue.
I was setting up Tailwind CSS in a React + Vite project and hit that frustrating wall where the styles just wouldn't apply. You know the feeling - you've followed the docs, everything looks right, but that beautiful blue bg-blue-500 just renders as plain white?
Turns out I'd missed three crucial things:
The content array in tailwind.config.js was empty (facepalm moment) - Tailwind needs to know which files to scan for class names!
PostCSS configuration - Vite uses it automatically but needs that postcss.config.js file to play nice with Tailwind
Import order matters - Those @tailwind directives need to be in your main CSS file (index.css, not App.css)
The fix was simple once I stepped back and checked the fundamentals:
Proper content paths: ["./index.html", "./src/*/.{js,ts,jsx,tsx}"]
Complete PostCSS setup with tailwindcss and autoprefixer
And of course, the classic "have you tried turning it off and on again?" (restarting the dev server)
Sometimes it's the obvious things that trip us up! What's your most recent "aha!" moment with CSS tooling?
