*{margin:0px;padding:0px;}
li{list-style: none;}
a{text-decoration: none;color: #6c6c6c;font-size: 13px;}
.clear{clear:both;}
.header{width:100%;background-color:#f5f5f5;}
.header_content{width:1200px;margin:0px auto;line-height:40px;}
.header_left{height:40px;float:left;}
.header_right{height:48px; float:right;}
.header_left a{display:inline-block;height:40px;text-align: center;position:relative;padding:0px 2px;}
.header_content a:hover{color:ff5000;}
.header_right{height:40px;float:right;}
.header_a{display:inline-block;height:40px;text-align:center;width:90px;position:relative;}
.header_a:hover{background-color:#fff;}
.header_a ul{border:1px solid #f5f5f5;display:none;border-top:none;}
.header_a:hover ul{display:block;position:absolute;width:100px;}
.header_a ul li{color:#6c6c6c;height:30px;line-height:30px;text-align:left;padding:0px 3px;margin:3px 0px;}
.header_a ul li:hover{background-color:#f5f5f5;}我在.header_a:hover ul{display:block;position:absolute;width:100px;}这里面加上margin-top:5px;就选不中li列表中的元素了，这是为什么呢？我是想让下拉列表与上面点击内容有一部分间隔。
