一种移动端position:absolute布局：
1.他父级不需要加上 position:relative; 如果父级不是不是body，则加position:absolute;
2.红色加量部分是必须加
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
<meta name="viewport" content="initial-scale=1, maximum-scale=1">
<style>
* {
margin: 0;
padding: 0;
}
body {
}
.header{
position: absolute;
100%;
height: 100px;
line-height: 100px;
background: red;
text-align: center;
}
.content { position: absolute; overflow: auto; 100%; top: 100px; right: 0; bottom: 0; left: 0; } </style> </head> <body> <div class="header">我是标题</div> <div class="content"> <div style="height:10000px;"></div> </div> </body> </html> <script> </script>
效果：
