<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title></title> <style type="text/css"> *{margin: 0;padding: 0;} html,body { width: 100%; height: 100%; margin: 0; padding: 0; font-size: 25px; font-weight: 700px; } .log { width: 100%; height: 100px; background: black; margin: 0 auto; /*水平居中*/ overflow: hidden; position: fixed;top:0px; } img{float: left;} .nav{float:right;text-align: center;line-height: 100px;} .nav a{padding: 50px;text-decoration: none;color: #fff;} .content{width: 100%;height: 100%;padding-top: 100px;padding-bottom:100px;} .content img{width:100%;} .foot{width: 100%;height: 100px;background: black;margin: 0 auto;position: fixed;bottom:0px;line-height: 100px;text-align: center;} .foot a{padding: 50px;text-decoration: none;color: #fff;} /*此处写代码*/ </style> </head> <body> <!-- 此处写代码 --> <div class="log"> <a href="#"><img src="http://img1.sycdn.imooc.com/climg//58c0d2d900016ce303000100.png"></a> <div class="nav"> <a href="#">课程</a> <a href="#">职业路径</a> <a href="#">实战</a> <a href="#">猿问</a> <a href="#">手记</a> </div> </div> <div class="content"> <img src="http://img1.sycdn.imooc.com/climg//58c0eda50001e12416000480.jpg"> <img src="http://img1.sycdn.imooc.com/climg//58c0edb80001c9f216000480.jpg"> <img src="http://img1.sycdn.imooc.com/climg//58c0edc9000100d516000480.jpg"> </div> <div class="foot"> <a href="#">教育中心</a> <a href="#">合作中心</a> <a href="#">人才招聘</a> <a href="#">常见问题</a> <a href="#">联系我们</a> </div> </body> </html>
