This article introduces in detail how to implement a simple secondary drop-down menu through code examples. Of course, there are also more complex secondary menus, but first learn how to make a simple one and share it with everyone for your reference. The specific content is as follows
The code is as follows:
<html>
<head>
<meta charset=" utf-8">
<title>下拉菜单</title>
<style type="text/css">
nav a{
text-decoration:none;
}
nav>ul>li{
float:left;
text-align:center;
padding:0 0.5em;
width:120px;
}
nav li ul.sub-menu{
display:none;
padding-left:0 !important;
}
.sub-menu li{color:white;}
.sub-menu li:hover{background-color:black;}
.sub-menu li:hover a{color:white;}
ul{list-style: none;}
</style>
<script type="text/javascript" src="mytest/jQuery/jquery-1.8.3.js"></script>
<script type="text/javascript">
$(document).ready(function(){
$('.box> li').hover(function(){
$(this).find('.sub-menu').css('display', 'block');
},function(){
$(this).find('.sub-menu').css('display', 'none');
});
});
</script>
</head>
