我在页面顶部有一个下拉菜单，如下所示：

CSS：

Live html 可以在这里找到，但我认为问题出在 CSS 上。 http://www.buffalolacrosse.com/test.cfm

我无法正确显示此菜单。它适用于 chrome 或 firefox，但不适用于 IE。菜单已折叠（li 填充不起作用）并且在垂直对齐时对齐完全不正常。感谢您的帮助。

我认为您需要a在菜单中指定元素的行高。我尝试通过设置

#coachnavigation a 
{ 
line-height:30px; 
}

我觉得很好。也添加z-index到您的菜单中，因此下拉菜单不会出现在某些元素后面。

div#navwrapper {
    z-index:999;
}
