Let's rewrite the same example and change the variable names, I think it make more sense now.

  import React from 'react';
  import { makeStyles } from '@material-ui/core/styles';
  import Button from '@material-ui/core/Button';
  
  const MyButtonClasses = makeStyles({
    root: {
      background: 'linear-gradient(45deg, #FE6B8B 30%, #FF8E53 90%)',
      border: 0,
      borderRadius: 3,
      boxShadow: '0 3px 5px 2px rgba(255, 105, 135, .3)',
      color: 'white',
      height: 48,
      padding: '0 30px',
    },
  });
  
  export default function MyButton() {
    const classes = MyButtonClasses();
    return <Button className={classes.root}>MyButton</Button>;
  }

This looks like much too complicated CSS mixed with Javascript. Or in other words: why must a button be created in such a complex way, when CSS and HTML can do the same?
