我做了一个网站，实现了一些东西，现在当我移动一些元素和CSS来组织和整理时，我的汉堡菜单在打开时停止显示。而不是滑下一个很好的动画导航栏消失，菜单不显示，如果我检查我可以看到，菜单在那里，但有一些覆盖它或一些不透明度是错误的。但是我去了我所有的z指数和不透明度，没有什么是错的，我可以看到。因此，我想让我的汉堡菜单时，点击显示一些帮助。
汉堡包只显示在移动的视图FYI
我将在下面包含一个片段，但这里是我认为导致问题的代码：

问题是nav元素没有高度。当通过添加menu-opened类打开菜单时，它变成position: absolute并具有固定的高度，父元素的高度为0，因为它折叠了。
我的建议是将menu-opened类添加到<nav>元素上，而不是.nav-menu上，然后在CSS中添加：

nav.menu-opened { 
  height: 100vh;
}

问题是导航菜单项的位置，请尝试用

.nav-menu.menu-opened {
    position: relative !important;
}

当一个元素有一个位置绝对的子元素时，父元素不计算它的高度，所以父容器的高度为零

请在导航css中删除position: sticky。
试试这个：

nav {
  position: unset;
}
