试试这个 CSS：

::-webkit-scrollbar {
  display: none;
}

Answer 2

我设法使用下面链接上发布的代码解决了问题。

https://github.com/mui-org/material-ui/issues/10739#issuecomment-817742141

下面是沙盒中的代码和链接。

import {
  AppBar,
  Box,
  CssBaseline,
  Grid,
  IconButton,
  makeStyles,
  Toolbar,
  Typography
} from "@material-ui/core";
import MenuIcon from "@material-ui/icons/Menu";
import "./styles.css";

const useStyles = makeStyles((theme) => {
  /*
   * This function creates a new object similar to `style`, but only keep
   * `property` with the value set from `setNewValue`.
   *
   * For example given the `style`:
   *
   * const style = {
   *   minHeight: 56,
   *   '@media (min-width:0px) and (orientation: landscape)': { minHeight: 48 },
   *   '@media (min-width:600px)': { minHeight: 64 }
   * }
   *
   * Then overrideExistingStyle(style, 'minHeight', (v) => v + 1) returns:
   *
   * {
   *   minHeight: 57,
   *   '@media (min-width:0px) and (orientation: landscape)': { minHeight: 49 },
   *   '@media (min-width:600px)': { minHeight: 65 }
   * }
   *
   * We use overrideExistingStyel to dynamically compute the main content
   * height. Since MUI AppBar minHeight depends on the screen size, We use
   * overrideExistingStyel() to set the minHeight of the main content to (100vh
   * - AppBar height).

  function overrideExistingStyle(style, property, setNewValue) {
    return Object.fromEntries(
