圣杯布局、双飞翼布局效果图

从效果图来看圣杯布局、双飞翼布局效果是一样一样的。

圣杯布局、双飞翼布局就是左右两侧宽度固定，中间内容宽度自适应，即100%

圣杯布局

<style>
    *{
        margin: 0;
        padding: 0;
        box-sizing: border-box;
    }
    .clearfix:before,
    .clearfix:after{
        display: table;
        content: " ";
        clear: both;
    }
    .container{
        padding: 0 200px;
    }
    .header,
    .footer{
        height: 200px;
        font-size: 28px;
        background-color: #f3f3f3;
    }
    .left{
        position: relative;
        /* 2、将.left再次拉到最左边，否则.main的左侧会有200px的空白 */
        left: -200px;
        float: left;
        width: 200px;
        min-height: 300px;
        /* 1、将.left拉到最左边，原来.left是掉下去的 */
        margin-left: -100%;
        background-color: #f00;
    }
    .main{
        float: left;
        width: 100%;
        min-height: 300px;
        background-color: #c32228;
    }
    .right{
        position: relative;
        /* 2、将.right再次拉到最右边，否则.main的右侧会有200px的空白 */
        right: -200px;
        float: left;
        width: 200px;
        /*/1、将.right拉到最右边，原来.right是掉下去的 */
        margin-left: -200px;
        min-height: 300px;
        background-color: #f90;
    }
</style>

<div class="header">header</div>
<div class="container clearfix">
    <div class="main">main</div>
    <div class="left">left</div>
    <div class="right">right</div>
</div>
<div class="footer">footer</div>

浮动实现双飞翼布局

<style>
    *{
        margin: 0;
        padding: 0;
        box-sizing: border-box;
    }
    .clearfix:before,
    .clearfix:after{
        display: table;
        content: " ";
        clear: both;
    }
    .header,
    .footer{
        height: 200px;
        font-size: 28px;
        background-color: #f3f3f3;
    }
    .left{
        float: left;
        width: 200px;
        min-height: 300px;
        /* 将.left拉到最左边，原来.left是掉下去的 */
        margin-left: -100%;
        background-color: #f00;
    }
    .main{
        float: left;
        width: 100%;
        min-height: 300px;
        /* .left、.right各占了200px，因此需要将其抵消掉 */
        padding: 0 200px;
        background-color: #c32228;
    }
    .right{
        float: left;
        width: 200px;
        /* 将.right拉到最右边，原来.right是掉下去的 */
        margin-left: -200px;
        min-height: 300px;
        background-color: #f90;
    }
    
</style>

<div class="header">header</div>
<div class="container clearfix">
    <div class="main">
        <div class="main-inner">main</div>
    </div>
    <div class="left">left</div>
    <div class="right">right</div>
</div>
<div class="footer">footer</div>

table-cell实现双飞翼布局(IE8也兼容哦~)

<style>
    *{
        margin: 0;
        padding: 0;
        box-sizing: border-box;
    }
    .container{
        display: table;
    }
    .header,
    .footer{
        height: 200px;
        font-size: 28px;
        background-color: #f3f3f3;
    }
    .left,
    .right,
    .main{
        /* 外层容器使用table-cell布局，设置元素为table-cell布局后它们就能在一行显示了，display: table-cell;设置宽度无效，
因此他们的宽度由内容撑开。 */
        display: table-cell;            
    }
    .left-inner{
        width: 200px;
        min-height: 300px;
        background-color: #f00;
    }
    .main{
        width: 100%;            
    }
    .main-inner{
        min-height: 300px;
        background-color: #c32228;
    }
    .right-inner{
        width: 200px;
        min-height: 300px;
        background-color: #f90;
    }
</style>

<div class="header">header</div>
<div class="container clearfix">
    
    <div class="left">
        <div class="left-inner">left</div>
    </div>
    <div class="main">
        <div class="main-inner">main</div>
    </div>
    <div class="right">
        <div class="right-inner">right</div>
    </div>
</div>
<div class="footer">footer</div>

绝对定位实现双飞翼布局

使用绝对定位实现有个小问题：父容器的高度只能由.main的高度来决定

<style>
    *{
        margin: 0;
        padding: 0;
        box-sizing: border-box;
    }
    .container{
        position: relative;
        padding: 0 200px;
    }
    .header,
    .footer{
        height: 200px;
        font-size: 28px;
        background-color: #f3f3f3;
    }
    .left{
        position: absolute;
        top: 0;
        left: 0;
        width: 200px;
        min-height: 300px;
        background-color: #f00;
    }
    .main{
        min-height: 300px;
        background-color: #c32228;
    }
    .right{
        position: absolute;
        top: 0;
        right: 0;
        width: 200px;
        min-height: 300px;
        background-color: #f90;
    }    
</style>

<div class="header">header</div>
<div class="container clearfix">
    <div class="left">left</div>
    <div class="main">mian</div>
    <div class="right">right</div>
</div>
<div class="footer">footer</div>

使用flex实现双飞翼布局(有兼容性问题)

<style>
    *{
        margin: 0;
        padding: 0;
        box-sizing: border-box;
    }
    .clearfix:before,
    .clearfix:after{
        display: table;
        content: " ";
        clear: both;
    }
    .container{
        display: flex;
    }
    .header,
    .footer{
        height: 200px;
        font-size: 28px;
        background-color: #f3f3f3;
    }
    .left{
        flex: 0 0 200px;
        width: 200px;
        min-height: 300px;
        background-color: #f00;
    }
    .main{
        flex: 1;
        width: 100%;
        min-height: 300px;
        background-color: #c32228;
    }
    .right{
        flex: 0 0 200px;
        width: 200px;
        min-height: 300px;
        background-color: #f90;
    }
</style>

<div class="header">header</div>
<div class="container clearfix">
    
    <div class="left">left</div>
    <div class="main">main</div>
    <div class="right">right</div>
</div>
<div class="footer">footer</div>
