javascript - 带有 HTML、CSS、JavaScript 的全屏覆盖菜单

问题描述

我正在尝试制作全屏覆盖导航菜单。而且我不知道我做错了什么。所以我使用一个复选框作为全屏导航菜单的切换器。并且还使用汉堡包作为按钮。

这可能有一个我似乎没有发现的小错误，但我是这方面的初学者。请帮忙

这是 HTML 代码

<body>
<div class="menu-wrap">
  <input type="checkbox" class="toggler">
  <div class="hamburger">
    <div>
    </div>
  </div>
</div>

<div class="fullpagemenu" id="menu">
  <div class="nav">
    <ul>
      <li><a href="#" data-text="home">Home</a></li>
      <li><a href="#" data-text="About">About</a></li>
      <li><a href="#" data-text="services">Services</a></li>
      <li><a href="#" data-text="Portfolio">Portfolio</a></li>
      <li><a href="#" data-text="Team">Team</a></li>
      <li><a href="#" data-text="Contact">Contact</a></li>
    </ul>
  </div>
</div>

<section class="landing">
  <img src="./circles.svg" alt="dots">
  <h1>Dots</h1>
</section>

<script type="text/javascript" src="/js/index.js"></script>

这是 index.js。这也可以正常工作，因为它可以切换 fullpagemenu div 中的活动类

const toggler = document.querySelector(".toggler");
const menu = document.querySelector("#menu");

toggler.addEventListener("click", () => {
  menu.classList.toggle("active");
});

这是 index.css。当我在 fullpagemenu 类中将顶部设置为 0 时，一切正常。

解决方案

你有一个空格.fullpagemenu .active，它应该是：.fullpagemenu.active编辑这个，你的代码可以工作：

const toggler = document.querySelector(".toggler");
const menu = document.querySelector("#menu");

toggler.addEventListener("click", () => {
  menu.classList.toggle("active");
});

  margin: 0;
  padding: 0;
