CSS 定位 - mobilemenubar

Question

我在项目中遇到了一个我不理解且不知道如何解决的问题。 我正在设计一个网站的移动菜单。 该问题仅发生在移动菜单中，因此要重现该问题，需要

菜单可以通过右上角的汉堡图标进行扩展。菜单工作正常，但是当菜单未展开时，在一些随机位置的菜单栏上，（只需将鼠标悬停在绿色区域上即可轻松找到它们）光标变为指针并单击启动菜单项（不可见而且我不知道为什么它可以在那里点击）

为了更容易定位问题，我将代码的重要行提取到此代码笔中：https://codepen.io/bvonr/pen/rNMEpqZ

(function(){
    var burger = document.querySelector('.burger-container'),
        header = document.querySelector('.header');
    
    burger.onclick = function() {
        header.classList.toggle('menu-opened');
        menu-item.classList.toggle('activemenu');
    }
}());

/*Header generell */

.header {
  width: 100%;
  background: #24603c;

/* Mobiles Menü */

如果有人知道菜单项出现在那里的原因以及我该如何解决这个问题，我将非常感谢您的帮助。

我正在为网站编写无薪代码，因此我远非专家，希望能提供任何帮助。

Answer 1

原因是这一行……​​：

transform: scale(1.15) translateY(-30px)

...在 .header ul.menu li.menu-item:nth-child(1) 的 CSS 规则中

或者更准确地说是translateY(-30px)，它将所有菜单链接向上移动 30 像素。

由于您用opacity: 0 隐藏了li 元素，所以顶部的li 仍然部分存在；不可见，但可点击（即标题中 overflow: hidden 未隐藏的部分）。

因此，您应该在列表项上使用display: none 而不是opacity: 0（或者在整个ul 上更好），或者避免使用transform: translateY(-30px) 设置
