Bootstrap导航条鼠标悬停下拉菜单

时间:2020-05-15 东成熙就人气:0

Bootstrap的导航条下拉菜单为了适应移动设备没有鼠标hover的状态，都是点击弹出下拉菜单，为了适应一般网站使用，我稍作了一些修改，鼠标hover时就弹出二级菜单。

效果图：

CSS修改：

<style type="text/css"> 
 .navbar .nav > li .dropdown-menu { 
 margin: 0; 
 } 
 .navbar .nav > li:hover .dropdown-menu { 
 display: block; 
 } 
</style>
