如何使用MaterialUI构建此布局？反应

npm install @material-ui/core

yarn add @material-ui/core

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

const useStyles = makeStyles((theme) => ({
  root: {
    flexGrow: 1,
  },
  paper: {
    padding: theme.spacing(2),
    textAlign: 'center',
    color: theme.palette.text.secondary,
  },
}));

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

  return (
    <div className={classes.root}>
      <Container maxWidth="lg">
        <Grid container spacing={3}>
          <Grid item xs={12}>
            <Paper className={classes.paper}>Header</Paper>
          </Grid>
          <Grid item xs={8}>
            <Paper className={classes.paper}>Content</Paper>
          </Grid>
          <Grid item xs={4}>
            <Paper className={classes.paper}>Sidebar</Paper>
          </Grid>
          <Grid item xs={12}>
            <Paper className={classes.paper}>Footer</Paper>
          </Grid>
        </Grid>
      </Container>
    </div>
  );
};

export default Layout;
