html - 3 列布局 HTML/CSS

Question

我有以下 HTML 布局:

<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>

是否有机会仅使用 CSS 在不更改 HTML 的情况下像下面的示例网格那样排列列？

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

Answer 1

应该这样做:

.column-left{ float: left; width: 33.333%; }
.column-right{ float: right; width: 33.333%; }
.column-center{ display: inline-block; width: 33.333%; }

要对更多的列执行此操作，您可以构建一个非常简单的网格系统。例如，像这样的东西应该适用于五列布局:

.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>

或者，如果您足够幸运能够只支持现代浏览器，您可以使用 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>
