推荐答案

CSS规范的Z-index段落说，新的堆栈上下文只创建一个z-index而不是auto的定位内容。

The CSS spec's paragraph on Z-index says that new stacking context is only created for positioned content with a z-index other than auto.

您有 li 里面 #nav 与位置：相对，显然是IE将其解释为一个新的堆叠上下文。

You have the li inside #nav with a position:relative, an apparently IE interprets this as a new stacking context.

尝试这样：

#nav li {
    display: block;
    position: relative;
    z-index: 1;         // force IE to recognize stack at this point
}
