CSS三列布局
两侧定宽中间自适应布局
思路一: float
【1】float + margin + calc
<style>p{margin: 0;}.parent{overflow: hidden;}.left,.right{float: left;width: 100px;}.center{float: left; width:calc(100% - 240px);margin: 0 20px;}</style>
<div class="parent" style="background-color: lightgrey;"> <div class="left" style="background-color: lightblue;"> <p>left</p> </div> <div class="center" style="background-color: pink;"> <p>center</p> <p>center</p> </div> <div class="right" style="background-color: lightgreen;"> <p>right</p> </div> </div>
【2】float + margin + (fix)
<style>p{margin: 0;}.parent{overflow: hidden;}.left,.right{position: relative;float: left;width: 100px;}.centerWrap{float: left; width:100%; margin: 0 -100px;}.center{margin: 0 120px;}</style>
<div class="parent" style="background-color: lightgrey;"> <div class="left" style="background-color: lightblue;"> <p>left</p> </div> <div class="centerWrap" style="background-color: red;"> <div class="center" style="background-color: pink;"> <p>center</p> <p>center</p> </div> </div> <div class="right" style="background-color: lightgreen;"> <p>right</p> </div> </div>
思路二: inline-block
【1】inline-block + margin + calc
<style>p{margin: 0;}.parent{font-size: 0;}.left,.right,.center{display:inline-block; vertical-align: top;font-size: 16px;}.left,.right{width: 100px;}.center{width: calc(100% - 240px); margin: 0 20px;}</style>
<div class="parent" style="background-color: lightgrey;"> <div class="left" style="background-color: lightblue;"> <p>left</p> </div> <div class="center" style="background-color: pink;"> <p>center</p> <p>center</p> </div> <div class="right" style="background-color: lightgreen;"> <p>right</p> </div> </div>
【2】inline-block + margin + (fix)
<style>p{margin: 0;}.parent{font-size: 0;}.left,.right,.centerWrap{display:inline-block; vertical-align: top;font-size: 16px;}.left,.right{width: 100px;position:relative;}.centerWrap{width: 100%; margin: 0 -100px;}.center{margin: 0 120px;}</style>
<div class="parent" style="background-color: lightgrey;"> <div class="left" style="background-color: lightblue;"> <p>left</p> </div> <div class="centerWrap" style="background-color: orange;"> <div class="center" style="background-color: pink;"> <p>center</p> <p>center</p> </div> </div> <div class="right" style="background-color: lightgreen;"> <p>right</p> </div> </div>
思路三: table
<style>p{margin: 0;}.parent{display: table; width: 100%;table-layout: fixed;}.left,.right,.centerWrap{display:table-cell;}.left,.right{width: 100px;}.center{margin: 0 20px;}</style>
<div class="parent" style="background-color: lightgrey;"> <div class="left" style="background-color: lightblue;"> <p>left</p> </div> <div class="centerWrap" style="background-color: orange;"> <div class="center" style="background-color: pink;"> <p>center</p> <p>center</p> </div> </div> <div class="right" style="background-color: lightgreen;"> <p>right</p> </div> </div>
思路四: absolute
<style>p{margin: 0;}.parent{position: relative;height:40px;}.left,.right,.center{position: absolute;}.left{left: 0;width:100px;}.right{right: 0;width: 100px;}.center{left: 120px; right: 120px;}</style>
<div class="parent" style="background-color: lightgrey;"> <div class="left" style="background-color: lightblue;"> <p>left</p> </div> <div class="center" style="background-color: pink;"> <p>center</p> <p>center</p> </div> <div class="right" style="background-color: lightgreen;"> <p>right</p> </div> </div>
思路五: flex
<style>p{margin: 0;}.parent{display: flex;}.left,.right{width: 100px;}.center{flex: 1; margin: 0 20px;}</style>
<div class="parent" style="background-color: lightgrey;"> <div class="left" style="background-color: lightblue;"> <p>left</p> </div> <div class="center" style="background-color: pink;"> <p>center</p> <p>center</p> </div> <div class="right" style="background-color: lightgreen;"> <p>right</p> </div> </div>
两列定宽一侧自适应布局
这种布局与单列定宽单列自适应布局非常相似
思路一: float
【1】float + margin
缺点是IE6-浏览器的3px的bug，以及当自适应列中有元素清除浮动时，会使该元素不与左侧浮动元素同行，从而出现文字下沉现象
<style>p{margin: 0;}.parent{overflow: hidden;}.left,.center{float: left;width: 100px;margin-right: 20px;}.right{margin-left: 240px;}</style>
<div class="parent" style="background-color: lightgrey;"> <div class="left" style="background-color: lightblue;"> <p>left</p> </div> <div class="center" style="background-color: pink;"> <p>center</p> </div> <div class="right" style="background-color: lightgreen;"> <p>right</p> <p>right</p> </div> </div>
【2】float + margin + calc
<style>p{margin: 0;}.parent{overflow: hidden;}.left,.center{float: left;width: 100px;margin-right: 20px;}.right{float: left; width: calc(100% - 240px);}</style>
<div class="parent" style="background-color: lightgrey;"> <div class="left" style="background-color: lightblue;"> <p>left</p> </div> <div class="center" style="background-color: pink;"> <p>center</p> </div> <div class="right" style="background-color: lightgreen;"> <p>right</p> <p>right</p> </div> </div>
【3】float + margin + (fix)
<style>p{margin: 0;}.parent{overflow: hidden;}.left,.center{position: relative; float: left;width: 100px;margin-right: 20px;}.rightWrap{float: left; width: 100%; margin-left: -240px;}.right{margin-left:240px;}</style>
<div class="parent" style="background-color: lightgrey;"> <div class="left" style="background-color: lightblue;"> <p>left</p> </div> <div class="center" style="background-color: pink;"> <p>center</p> </div> <div class="rightWrap"> <div class="right" style="background-color: lightgreen;"> <p>right</p> <p>right</p> </div> </div> </div>
【4】float + overflow
<style>p{margin: 0;}.parent{overflow: hidden;}.left,.center{position: relative; float: left;width: 100px;margin-right: 20px;}.right{overflow: hidden;zoom:1;}</style>
<div class="parent" style="background-color: lightgrey;"> <div class="left" style="background-color: lightblue;"> <p>left</p> </div> <div class="center" style="background-color: pink;"> <p>center</p> </div> <div class="right" style="background-color: lightgreen;"> <p>right</p> <p>right</p> </div> </div>
思路二: inline-block
【1】inline-block + margin + calc
<style>p{margin: 0;}.parent{font-size: 0;}.left,.right,.center{display:inline-block; vertical-align: top;font-size: 16px;}.left,.center{width: 100px;margin-right:20px;}.right{width: calc(100% - 240px);}</style>
<div class="parent" style="background-color: lightgrey;"> <div class="left" style="background-color: lightblue;"> <p>left</p> </div> <div class="center" style="background-color: pink;"> <p>center</p> </div> <div class="right" style="background-color: lightgreen;"> <p>right</p> <p>right</p> </div> </div>
【2】inline-block + margin + (fix)
<style>p{margin: 0;}.parent{font-size: 0;}.left,.rightWrap,.center{display:inline-block; vertical-align: top;font-size: 16px;}.left,.center{position: relative;width: 100px;margin-right:20px;}.rightWrap{width:100%; margin-left: -240px;}.right{margin-left: 240px;}</style>
<div class="parent" style="background-color: lightgrey;"> <div class="left" style="background-color: lightblue;"> <p>left</p> </div> <div class="center" style="background-color: pink;"> <p>center</p> </div> <div class="rightWrap" style="background-color: green;"> <div class="right" style="background-color: lightgreen;"> <p>right</p> <p>right</p> </div> </div> </div>
思路三: table
<style>p{margin: 0;}.parent{display: table; width: 100%;table-layout: fixed;}.leftWrap,.centerWrap,.right{display:table-cell;}.leftWrap,.centerWrap{width: 120px;}.left,.center{margin-right: 20px;}</style>

思路四: absolute
<style>p{margin: 0;}.parent{position: relative;width:100%;height:40px;}.left{position: absolute;left:0;width:100px;}.center{position: absolute;left:120px;width: 100px;}.right{position: absolute;left:240px; right:0;}</style>
<div class="parent" style="background-color: lightgrey;"> <div class="left" style="background-color: lightblue;"> <p>left</p> </div> <div class="center" style="background-color: pink;"> <p>center</p> </div> <div class="right" style="background-color: lightgreen;"> <p>right</p> <p>right</p> </div> </div>
思路五: flex

思路二: table
<style>p{margin: 0;}.parent{display: table; width: 100%;}.leftWrap{display: table-cell; width: 0.1%;}.centerWrap{display: table-cell;width: 120px;}.left,.center{margin-right: 20px;}.right{display:table-cell;}</style>
