我想将订单面板和订单菜单并排放置，它们是两个不同的组件（容器）。在我的CSS中，我尝试了display: inline-block 和flex-direction:row。我已经在父组件（Order）上尝试了 flex，但它减少了两个组件的宽度。这是很简单的事情，但我做不到。有人可以指导我找出错误吗？

import React from "react";
import Container from "@material-ui/core/Container";
import Stack from "@mui/joy/Stack";
import OrderPanel from "./OrderPanel";
import OrderMenu from "./OrderMenu";
import "./Order.css";


function Order()  {
  return (
    <>
      <div className="Order">
          <OrderPanel />
          <OrderMenu/>
      </div>
    </>
  );
  
};

export default Order;

import React from "react";
import Container from "@material-ui/core/Container";
import Stack from "@mui/joy/Stack";
import OrderPanel from "./OrderPanel";
import "./Order.css";


function OrderMenu() {
  return (
    <>
      <div className="Order-Menu">
        <Container>Order Menu</Container>
      </div>
    </>
  );
}

export default OrderMenu;


import React from "react";
import Container from "@material-ui/core/Container";
import Stack from "@mui/joy/Stack";
import "./Order.css";
import Order from "./Order";

function OrderPanel() {
  return (
    <>
      <div className="Order-Panel">
        <Container>Order Panel</Container>
      </div>
    </>
  );
}

export default OrderPanel;

.Order {
    background-color:darkkhaki;
    height: 50%;
    flex-direction: row;
}

.Order-Panel{
    background-color: beige;
    margin-left: 2vw;
    margin-right: 60vw;
    margin-top: 2vh;
    height: 60vh;
    width: 50vh;
    flex-direction: row;
    display: inline-block;
    
}

.Order-Menu{
    background-color: aquamarine;
    margin-top: 2vh;
    margin-left:2vw;
    height:10vw;
    width: 45vh;
    display: inline-block;
    flex-direction: row;
}
