Question

我对javascript有点新鲜，并使用一个小的来让我的菜单显示为相应地移动按钮但我想实现子菜单。现在，当我想要在子菜单被激活时（在主要li上悬停）按钮移动时，它就赢了。

我做错了什么？

一个小小的注意事项，如果没有激活菜单，那么菜单也会扩展（在第二个悬停时），这是我的第二个问题。

    content:'';
}
#nav-toggle span:before {
    top: 10px;
}
#nav-toggle span:after {
    bottom: 10px;
}
#nav-toggle span, #nav-toggle span:before, #nav-toggle span:after {
    transition: all 500ms ease-in-out;
}
#nav-toggle.active span {
    background-color: transparent;
}
#nav-toggle.active span:before, #nav-toggle.active span:after {
    top: 0;
}
#nav-toggle.active span:before {
    transform: rotate(45deg);
}
#nav-toggle.active span:after {
    transform: rotate(-45deg);
}

Answer 1

设置 position: relative button.toggle-nav和删除 top: 30px;，

看看这个JSFiddle

Answer 2

try this css code
#nav-toggle {
    z-index: 10000000;
    position: fixed;
    cursor: pointer;
    padding: 5px 10px 10px 10px;
    top: 0px;
}

无法在按钮上移动li：在.active时将鼠标悬停
