如何编写！重要的是在@material-ui中使用useStyles

import { makeStyles } from '@material-ui/core/styles';

const useStyles = makeStyles((theme) => ({
  // 样式属性
}));

const classes = useStyles();

<div className={classes.sampleClass}>Sample Content</div>

import React from 'react';
import { makeStyles } from '@material-ui/core/styles';

const useStyles = makeStyles((theme) => ({
  sampleClass: {
    backgroundColor: 'blue',
    color: 'white',
    fontSize: '16px',
    padding: '10px',
    margin: '5px',
  },
}));

const MyComponent = () => {
  const classes = useStyles();

  return (
    <div className={classes.sampleClass}>
      Sample Content
    </div>
  );
};

export default MyComponent;
