1、新建html文档。
4、书写css代码。<style type="text/css">*{border:0;margin:0;padding:0;}body{font-family:'Microsoft Yahei','微软雅黑',Arial,'Hiragino Sans GB','宋体';font-size:14px; }ul{list-style:none;}/* slides */.slides{position:fixed;right:0;top:45%;}.slides .slideul>li{position:relative;display:block;width:56px;height:56px;margin-bottom:10px;overflow:visible;}.slides .slideul>li.kefu{width:66px;padding-left:10px;margin-left:-10px;}.slides .slideul>li ul.kefulist{position:absolute;left:-86px;top:-30px;padding-right:10px;display:none;}.slides .slideul>li ul.kefulist li{margin-bottom:10px;}.slides .slideul>li ul.kefulist li a{display:block;width:90px;height:30px;line-height:30px;background:#a8defe;color:#fff;text-align:center;text-decoration:none;}.slides .slideul>li ul.kefulist li a:hover{text-decoration:none;}</style>
6、代码整体结构。
