我这里是我的水平菜单代码。现在我想把它改成垂直菜单。我不知道该怎么做。请帮我怎么做。我尝试改变宽度但没有发生。我没有在哪里编辑<ul><li>标签以将其更改为垂直。请建议我
#menu {
background: url('../image/menu.png') repeat-x;
position: relative;
z-index: 1;
height: 34px;
clear: both;
padding: 0px 30px;
min-width: 900px;
}
#menu > ul.left {
float: left;
}
#menu > ul.right {
float: right;
}
#menu > ul {
position: relative;
margin: 0;
padding: 0;
}
#menu > ul ul {
list-style: none;
margin: 0;
padding: 0;
background: url('../image/transparent.png');
}
