title: Tailwindcss V3.0.1 classes is not working
body: <p>I tried to install the tailwindcss 3.0.1 using this guide but when I added tailwindcss classes to my react code, it didn't work.
  I followed this guide to integrate tailwind to react: <a href="https://tailwindcss.com/docs/guides/create-react-app" rel="noreferrer">https://tailwindcss.com/docs/guides/create-react-app</a></p>
  <p>I created a react app using <code>npx creat-react-app myApp</code> instead of <code>npx create-react-app@next --scripts-version=@next --template=cra-template@next my-project</code></p>
  <p>anyone please help me with this.</p>
