汉堡菜单在单击移动设备中的任何链接时不会折叠

Question

我正在建立一个网站，遇到了这个问题。我有一个基本的导航栏，当在手机上查看时，它看起来像汉堡菜单。菜单很好用。我使用了纯HTML-CSS代码来制作这个导航栏。问题是，当我点击菜单上的任何链接导航到页面的不同部分时，导航栏都不会关闭。

HTML:

<header class="navbar-fixed-top">
<div class="container">
<nav>
<input type="checkbox" id="nav" class="hidden">
<label for="nav" class="nav-btn">
<i></i>
<i></i>
<i></i>
</label>
<div class="nav-wrapper">
<ul>
<li><a href="#home">HOME</a></li>
<li><a href="#mint">MINT</a></li>
<li><a href="#community">COMMUNITY</a></li>
<li><a href="#projects">PROJECTS</a></li>
<li><a href="#faq">FAQ</a></li>
</ul>
</div>
</nav>
</div>
</header>

CSS

header {
text-align: right;

抱歉代码太长由于我是一个几乎没有JS经验的初学者，我想知道是否有任何解决方案。CSS中有什么解决方案吗？或者我们需要使用JS吗。如有任何帮助，将不胜感激

我认为你不能只使用CSS，因为它需要child->父母关系。

如果你可以使用JS，你可以设置"；false"；到#nav复选框

const onLinkClick = () => {
document.querySelector("#nav").checked = false; // Once link is clicked -> make #nav checkbox false thus close the menu
};
document
.querySelectorAll(".nav-wrapper a") // Grab all links
.forEach((element) => element.addEventListener("click", onLinkClick)); // Listen for click on them
