float
- float+calc
通过calc()函数计算出.middle元素的高度,并设置子元素高度为100%
<style>
body,p{margin: 0;}
body,html,.parent{height: 100%;}
.middle{
overflow: hidden;
height: calc(100% - 100px);
}
.left{
float: left;
width: 100px;
margin-right: 20px;
height: 100%;
}
.right{
overflow: auto;
height: 100%;
}
.right-in{
height: 1000px;
}
.top,.bottom{height:50px;}
</style>
<div class="parent" id="parent" style="background-color: lightgrey;">
<div class="top" style="background-color: lightblue;">
<p>top</p>
</div>
<div class="middle" style="background-color: pink;">
<div class="left" style="background-color: orange;">
<p>left</p>
</div>
<div class="right" style="background-color: lightsalmon;">
<div class="right-in">

</div>
</div>
</div>
<div class="bottom" style="background-color: lightgreen;">
<p>bottom</p>
</div>
</div>
- float + absolute + (fix)
通过增加结构来提高兼容性,.middle元素设置100%的高度,.top和.bottom设置absolute覆盖在.middle上
<style>
body,p{margin: 0;}
body,html,.parent{height: 100%;}
.top,.bottom{
position: absolute;
height:50px;
left: 0;
