I found that the Official Website of Material UI is using @material-ui and @mui.
But I find that If I use @material-ui or @mui Textfield, the UI doesn't works and the problems are mentioned below
React - Material label not in right position in Textfield
If you search Material UI in google, and go to https://mui.com/, it tells you to npm install @mui/material. But few weeks ago, I am using npm install @material-ui
If I have both @material-ui and @mui in my package.json, and I include both script and stylesheet in index.html, will there be any conflicts which mess up the UI
Update 1
In @mui CodeSandbox,
If you try Textfield with select prop, when you open the select, overflow: hidden will be added in body.

In my project,
overflow: hidden; padding: 15px is added in body, but I checked I've done nothing about this!
