How to add PostCSS with Material UI style support to a CRA project?

[ghost]

As far as I know, It's not recommended to change Webpack configuration for a CRA project. So how can I add PostCSS to my project? I want to use 'autoprefixer' plugin of PostCSS and I also need to this plugin work with MUI if possible. I almost checked most of the solution on the web but none of them working.

Any help will be appreciated.

Create React App uses autoprefixer by default https://create-react-app.dev/docs/post-processing-css/

There is also an official example of using CRA with MUI in the MUI repository https://github.com/mui-org/material-ui/tree/master/examples/create-react-app

If you use CSS-in-JS styling, it won't work.
For checking, create some styles with Material UI makeStyles function and test.
