Css can´t find tailwind

You need to confirm the followings:

1. Check if tailwind actually works.

Please try to apply the following code as an example.

<div className="text-3xl font-bold">Example Title</div>

If you see the correct style, then your configuration is fine and there is no problem at all. So you need to check IDE.

Otherwise, you need to confirm the version of Tailwind you installed and its tailwind.config.js.

2. IDE doesn't recognize the tailwind.

Please try to install plugins related to tailwind in VS Code.
