我使用以下 HTML 程序创建带有水平子菜单的水平菜单栏。它在 Fire Fox 和 Chrome 中运行良好,但在 IE 中不起作用。那么这个程序需要更改哪些更改?
<html>
<head>
<style>
/* Targeting both first and second level menus */
#nav li {
list-style:none;
float: left;
position: relative;
}
#nav li a {
display: block;
padding: 8px 12px;
text-decoration: none;
}
#nav li a:hover {
background-color:red;
color:#FFF;
opacity:1;
}
/* Targeting the first level menu */
#nav {
top:150px;
min-width:850px;
background:#fff;
opacity:0.5;
display: block;
height: 34px;
z-index: 100;
position: absolute;
}
#nav > li > a {
}
/* Targeting the second level menu */
#nav li ul {
color: #333;
display: none;
position: absolute;
width:850px;
}
#nav li ul li {
display: inline;
}
#nav li ul li a {
background: #fff;
border: none;
line-height: 34px;
margin: 0;
padding: 0 8px 0 10px;
}
#nav li ul li a:hover {
background-color:red;
color:#FFF;
opacity:1;
}
/* Third level menu */
#nav li ul li ul{
top: 0;
}
ul.child {
background-color:#FFF;
}
/* A class of current will be added via jQuery */
#nav li.current > a {
background: #f7f7f7;
float:left;
}
/* CSS fallback */
#nav li:hover > ul.child {
left:0;
top:34px;
display:inline;
position:absolute;
text-align:left;
}
#nav li:hover > ul.grandchild {
display:block;
}
</style>
</head>
