解决方案主要有五种
首先写入全局样式
<style type="text/css">
html * {
margin: ;
padding: ;
}
.layout {
margin-top: 20px;
}
.layout article div {
min-height: 100px;
}
</style>
1、用浮动解决方案
缺点:清除浮动,脱离文档流
优点:兼容性好
<section class="layout float">
<style media="screen">
.layout.float .left {
float: left;
width: 300px;
background: red;
}
.layout.float .right {
float: right;
width: 300px;
background: blue;
}
.layout.float .center {
background: yellow;
text-align: center;
}
</style>
<article class="left-right-center">
<div class="left"></div>
<div class="right"></div>
<div class="center">

width: 300px;
left: 0;
}
.layout.absolute .right {

3、flexbox布局解决方案
优点:为了解决绝对定位和浮动不足,基本比较完美,移动端基本是flexbox
<section class="layout flexbox">

.layout.flexbox {
margin-top: 150px;
}
.layout.flexbox .left-center-right {
display: flex;
}
.layout.flexbox .left {
width: 300px;
background: red;
}
.layout.flexbox .right {
width: 300px;
background: blue;
}
.layout.flexbox .center {
flex: 1;
background: yellow;
text-align: center;
}
</style>

.layout.table .left-center-right {
width: 100%;
display: table;
height: 100px;
}
.layout.table .left-center-right > div {
