用一下的代码为例：
<body> <ul class="nav"> <li><a class="on" href="#">首 页</a></li> <li><a href="#">新闻快讯</a></li> <li><a href="#">产品展示</a></li> <li><a href="#">售后服务</a></li> <li><a href="#">联系我们</a></li> </ul> </body>
1.水平菜单的制作：
*{margin:0; padding:0; font-size:14px;} ul{ list-style:none;} a{color:#333;text-decoration:none} .nav li{ float:left;} .nav li a{ display:block; text-indent:20px; height:30px; line-height:30px; width:100px; background-color:#efefef; margin-bottom:1px;} .nav li a:hover{ background-color:#F60; color:#fff}
2.圆角菜单的制作：
*{margin:0; padding:0; font-size:14px;} a{color:#333;text-decoration:none} .nav{list-style:none; height:30px; border-bottom:10px solid #F60; margin-top:20px; padding-left:50px;} .nav li{float:left} .nav li a{display:block; height:30px;text-align:center; line-height:30px; width:120px; border-radius:12px 12px 0 0; margin-left:1px;background-color:#ddd;} .nav li a.on, .nav li a:hover{background-color:#F60; color:#fff;}
3.高度改变的伸缩导航：
*{margin:0; padding:0; font-size:14px;} a{color:#333;text-decoration:none} ul{list-style:none; height:50px; border-bottom:5px solid #F60; padding-left:30px;} ul li{float:left; margin-top:20px;} a{display:block;height:30px;text-align:center; line-height:30px; width:120px; background-color:#ccc;} a.on, a:hover{ color:#fff;background-color:#F60;height:40px; line-height:40px;margin-top:-10px;}
4.水平伸缩导航：
* { margin: 0; padding: 0; font-size: 14px; } a { color: #333; text-decoration: none } ul { list-style: none; height: 30px; border-bottom: 5px solid #F60; margin-top: 20px; padding-left: 50px; } ul li { float: left } ul li a { display: block; height: 30px; text-align: center; line-height: 30px; width:120px; background: #efefef; margin-left: 1px; } a.on, a:hover { background: #F60; color: #fff; }
<script> window.onload=function(){ var aA=document.getElementsByTagName('a'); for(var i=0; i<aA.length; i++){ aA[i].onmouseover=function(){ var This=this; clearInterval (This.time); This.time= setInterval (function(){ This.style.width=This.offsetWidth+8+"px"; if(This.offsetWidth >=160) clearInterval(This.time); },30) } aA[i].onmouseout=function(){ clearInterval(this.time); var This=this; this.time=setInterval(function(){ This.style.width=This.offsetWidth-8+"px"; if(This.offsetWidth<=120){ This.style.width='120px'; clearInterval(This.time); } },30) } } } </script>
