如何在div中居中“阿凡达”素材UI组件？使用ReactJS和material UI

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

const useStyles = makeStyles({
  container: {
    display: 'flex',
    justifyContent: 'center',
    alignItems: 'center',
    height: '100vh',
  },
});

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

  return (
    <Box className={classes.container}>
      {/* 在这里添加你的"阿凡达"素材UI组件 */}
    </Box>
  );
};

export default MyComponent;
