The v0 preview version is correct, elegant and beautiful. However, when I deploy it, it changes completely and I don’t understand why. I’ve tried several times to fix it but without success. Can anyone help me?

Welcome to the Vercel Community, Laeffyy!
From your screenshots, it looks like a styling mismatch between your v0 preview and deployment. This usually comes down to one of these:
Common causes:
- Missing dependencies (Tailwind CSS, shadcn/ui components, etc.)
- CSS not loading/configured correctly in production
- Build differences between v0 preview and deployment
Quick checks:
- Confirm your
tailwind.config.jsis set up correctly - Ensure all shadcn/ui components are installed (
npx shadcn-ui@latest add [component-name]) - Verify CSS imports in your main layout file
- Try a clean rebuild + redeploy
To help further, could you share your v0 chat URL, and any console errors you’re seeing?
I encountered exactly the same problem. The preview is normal while coding, but after deploying to Vercel, the UI has some errors. If downloaded and deployed locally, the UI is completely broken.
I have tried for a whole day without finding the error.I hope the official staff can personally try it out and work to resolve the issue. This is very important for those of us who want to design web pages ourselves. If there are unsolvable issues during the production phase, we will completely abandon this tool.
This is the project I tried to deploy:https://v0.app/community/HtbHDROso0j the UI has serious errors when deployed locally.
