Bootstrap导航条鼠标悬停下拉菜单

时间:2021-07-01 10:21:17 帮助过:10人阅读

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>

实例源码:

<!DOCTYPE html> 
<html> 
<head> 
 <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> 
 <title>Bootstrap导航条鼠标悬停下拉菜单</title>
