添加内容div时无法在悬停时访问子菜单

I am trying to design a website with a horizantal navigation bar and with a side bar. The problem started when I added a div (content) which is obstructing the submenu

You simply need to increase the z-index of the submenu, by e.g. adding

您只需要增加子菜单的z-index，例如：加入

.nav ul ul{
  z-index:99;
}

The z-index property specifies the z-order of an element and its descendants. When elements overlap, z-order determines which one covers the other. An element with a larger z-index generally covers an element with a lower one.

z-index属性指定元素及其后代的z顺序。当元素重叠时，z顺序决定哪一个覆盖另一个。具有较大z指数的元素通常覆盖具有较低z元素的元素。

Although a value of 99 is likely excessive in this case, z-index effectively dictates the layering precedence of the element in question. note that in order to apply, the element will also need a position set (which your sub menu's already have)

虽然在这种情况下99的值可能过大，但z-index有效地决定了所讨论元素的分层优先级。请注意，为了申请，该元素还需要一个位置集（您的子菜单已经有）

#3

Add

加

.content{
    z-index: -100;
}

The content was like becoming an overlay on your dropdown menu item. So the cursor active scope was getting lost.

内容就像成为您的下拉菜单项上的叠加层。因此游标活动范围正在丢失。

or add z-index in positive value for the menu

或者为菜单添加正值的z-index
