Holy Grail layout and double flying wing layout renderings

From the renderings, the effects of the Holy Grail layout and the double flying wing layout are the same of.
Holy Grail Layout and Double Flying Wing Layout are fixed widths on the left and right sides, and the width of the middle content is adaptive, that is, 100%

Holy Grail Layout

<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>

Floating to achieve double flying wings Layout

<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 realizes double flying wing layout (IE8 is also compatible~)

<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>

Absolute positioning realizes double flying wing layout

There is a small problem in using absolute positioning: The height of the parent container can only be determined by the height of .main

<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>

Use flex to implement double flying wing layout (there are compatibility issues)

<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>
