html - 如何修复 div 上的导航栏显示？

Question

我正在用 React 做一个个人项目，我按照教程开发了一个导航侧边栏。

在我向主页添加某种卡片之前，它运行良好。现在，代表卡片的 div 显示在导航栏上，而不是在导航栏上。

我将附上一些照片以及导航栏的代码、它的 css 以及卡片代码和 css。

导航栏js

import * as FaIcons from "react-icons/fa";
import * as AiIcons from "react-icons/ai";
import { Link } from "react-router-dom";
import { SidebarData } from "./SidebarData";
import "./Navbar.css";
import { IconContext } from "react-icons";

function Navbar() {
  const [sidebar, setSidebar] = useState(false);

  const showSidebar = () => setSidebar(!sidebar);

  return (
    <>
      <IconContext.Provider value={{ color: "#fff" }}>
        <div className="navbar">
          <Link to="#" className="menu-bars">
            <FaIcons.FaBars onClick={showSidebar} />
          </Link>
        </div>
        <nav className={sidebar ? "nav-menu active" : "nav-menu"}>
          <ul className="nav-menu-items" onClick={showSidebar}>
            <li className="navbar-toggle">
              <Link to="#" className="menu-bars">
                <AiIcons.AiOutlineClose />
              </Link>
            </li>
            {SidebarData.map((item, index) => {
              return (
                <li key={index} className={item.cName}>
                  <Link to={item.path}>
                    {item.icon}
                    <span>{item.title}</span>
                  </Link>
                </li>
              );
            })}
          </ul>
        </nav>
      </IconContext.Provider>
    </>
  );
}

export default Navbar;

导航栏 CSS

.navbar {

.navbar-toggle {

  display: flex;
  justify-content: flex-start;

  z-index: 2;
}

span {
  margin-left: 16px;
}

卡片JS

import React from "react";
import "./Cards.css";

function Cards() {
  return (
    <>
      <div className="cards-wrapper">
        <div className="card">
          <div className="card-image"></div>
          <div className="card-title">
            <p></p>
          </div>
        </div>
        <div className="card-1">
          <div className="card-image"></div>
          <div className="card-title-1"></div>
        </div>
        <div className="card">
          <div className="card-image"></div>
          <div className="card-title"></div>
        </div>
        <div className="card-1">
          <div className="card-image"></div>
          <div className="card-title-1"></div>
        </div>
        <div className="card">
          <div className="card-image"></div>
          <div className="card-title"></div>
        </div>
      </div>
    </>
  );
}

export default Cards;

卡片 CSS

.cards-wrapper {
  display: flex;
  align-items: center;
  justify-content: space-evenly;
  padding-top: 6rem;
}

.card {
  position: absolute;
  height: 500px;
  width: 240px;
  background-color: black;
  padding-left: 100px;
  z-index: 1;
}
.card-1 {
  height: 500px;
  width: 240px;
  background-color: black;
}

我将不胜感激任何帮助！

尝试在你的类中添加额外的属性

 .navbar {
      position: absolute;
      z-index: 999;
      left: 0;
      top: 0
      background-color: #9f4650;
      height: 80px;
      display: flex;
      justify-content: flex-start;
      align-items: center;
    }
