推荐答案
css中有很多重复的样式.尝试消除那些.特别是ul有很多规则可以相互替代.尝试对您的ul的不同级别使用类，以使规则更具体.
You have a lot of duplicate styles in your css. Try to eliminate those. Especially the uls have a lot of rules which override each other. Try to use classes for the different levels of your uls to make to rules more specific.
您需要的所有CSS代码:( 对其进行测试)
all the css code you need: (test it)
#nav, #nav ul {
line-height: 1.5em;
list-style:none; /* <- shorthand declaration is enough */
margin: 0;
padding: 0;
position: relative;
}
#nav a:link, #nav a:active, #nav a:visited {
background-color: #333333;
border: 1px solid #333333;
color: #FFFFFF;
display: block;
padding: 0 5px;
text-decoration: none;
}
#nav a:hover {
background-color: #FFFFFF;
color: #333333;
}
#nav li {
position: relative;
width: 80px; /* <- This defines the width, no need to declare elsewhere */
}
#nav ul {
display: none;
left: 100%; /* <- % makes you indepentent of declared with in li*/
position: absolute;
top:0;
}
#nav li:hover > ul{
display:block; /* <- does all the hovermagic for you, no matter how many ul-levels you have */
}
出于多种原因，该代码无法在IE 6中运行(如果需要支持，则需要一些非常讨厌的解决方法)
for several reasons, this code wont work in IE 6 (if you need to support it, you need some really nasty workarounds)
