3列布局HTML / CSS [英] 3 column layout HTML/CSS

问题描述

我有以下HTML布局：

 < div class =container> 
< div class =column-center>列中心< / div> 
< div class =column-left>左列< / div> 
< div class =column-right>右列< / div> 
< / div> 
 

任何机会像下面的示例网格一样排列列，而不改变HTML 仅使用CSS？

  --------------------- ------------------------------- 
 | | | | 
 |左栏|列中心|列右| 
 | | | | 
 ---------------------------------------------- ------ 
  




解决方案

it：

  .column-left {float：left;宽度：33％; } 
 .column-right {float：right;宽度：33％; } 
 .column-center {display：inline-block;宽度：33％; } 
  

DEMO

EDIT

列可以构建一个非常简单的网格系统。例如，类似这样的应该适用于五列布局：

  .column {float：left;位置：相对; width：20％; / *仅供演示* / background：＃f2f2f2; border：1px solid＃e6e6e6; column-offset-3 {left：20％;} column-offset-2 {left：40％;} column-offset-3 {left：60％;} -offset-4 {left：80％;} column-inset-1 {left：-20％;} column-inset-2 {left：-40％;} column-inset-3 {left：-60 ％;}。column-inset-4 {left：-80％;}  

 < div class =container> < div class =column column-one column-offset-2>第一列< / div> < div class =column column-two column-inset-1>第二列< / div> < div class =column column-three column-offset-1>第三列< / div> < div class =column column-four column-inset-2>第四列< / div> < div class =column column-five>第五列< / div>< / div>  

或者，如果您足够幸运，只能支持现代浏览器，则可以使用 灵活框 ：

  .container {display： flex;}。column {flex：1; / *仅供演示* / background：＃f2f2f2; border：1px solid＃e6e6e6; box-sizing：border-box;}。column-one {order：3;}。column-two {order：1;}。column-three {order：4;}。 column-five {order：5;}  

 < div class =container> < div class =column column-one>第一列< / div> < div class =column column-two>第二列< / div> < div class =column column-three>第三列< / div> < div class =column column-four>第四列< / div> < div class =column column-five>第五列< / div>< / div>  

I have the following HTML layout:

<div class="container">
   <div class="column-center">Column center</div>
   <div class="column-left">Column left</div>
   <div class="column-right">Column right</div>
</div>

Any chance to arrange the columns like on the below sample grid without changing HTML using CSS only?

----------------------------------------------------
|              |                   |               |
| Column left  |   Column center   | Column right  |
|              |                   |               |
----------------------------------------------------

解决方案

Something like this should do it:

.column-left{ float: left; width: 33%; }
.column-right{ float: right; width: 33%; }
.column-center{ display: inline-block; width: 33%; }

EDIT

To do this with a larger number of columns you could build a very simple grid system. For example, something like this should work for a five column layout:

.column {
    float: left;
    position: relative;
    width: 20%;
  
    /*for demo purposes only */
    background: #f2f2f2;
    border: 1px solid #e6e6e6;
    box-sizing: border-box;
}

.column-offset-1 {
    left: 20%;
}
.column-offset-2 {
    left: 40%;
}
.column-offset-3 {
    left: 60%;
}
.column-offset-4 {
    left: 80%;
}

.column-inset-1 {
    left: -20%;
}
.column-inset-2 {
    left: -40%;
}
.column-inset-3 {
    left: -60%;
}
.column-inset-4 {
    left: -80%;
}

<div class="container">
   <div class="column column-one column-offset-2">Column one</div>
   <div class="column column-two column-inset-1">Column two</div>
   <div class="column column-three column-offset-1">Column three</div>
   <div class="column column-four column-inset-2">Column four</div>
   <div class="column column-five">Column five</div>
</div>

Or, if you are lucky enough to be able to support only modern browsers, you can use flexible boxes:

.container {
    display: flex;
}

.column {
    flex: 1;
    
    /*for demo purposes only */
    background: #f2f2f2;
    border: 1px solid #e6e6e6;
    box-sizing: border-box;
}

.column-one {
    order: 3;
}
.column-two {
    order: 1;
}
.column-three {
    order: 4;
}
.column-four {
    order: 2;
}
.column-five {
    order: 5;
}

<div class="container">
   <div class="column column-one">Column one</div>
   <div class="column column-two">Column two</div>
   <div class="column column-three">Column three</div>
   <div class="column column-four">Column four</div>
   <div class="column column-five">Column five</div>
</div>
