CSS文件：
body{
margin:0;
padding:0;
}
.header {
background:orange;
height:100px;
}
.footer{
background: greenyellow;
height:300px;
}
.article{
background:beige;
overflow: hidden;
}
.article .middle{
float:left;
background: #dbae58;
width:100%;
margin-bottom:-9999px;
padding-bottom:9999px;
}
.article .right{
background: #213aff;
float: left;
width:100px;
margin-left: -100px;
margin-bottom:-9999px;
padding-bottom:9999px;
}
.article .left{
background: green;
float:left;
width:150px;
margin-left: -100%;
margin-bottom:-9999px;
padding-bottom:9999px;
}
.article .inner{
background: #50cd35;
margin-left:150px;
margin-right:100px;
margin-bottom:-9999px;
padding-bottom:9999px;
}
主要是通过给padding-bottom一个较大的正值，margin-bottom一个大小一样的负值，外层容器overflow：hidden；实现登高布局，保证容器内高度大小跟随内容变化
