# 栅格布局
|
|
|
|
|
|
> Layui 栅格系统是一套具备响应式能力的布局方案，采用业界比较常用的容器横向 `12` 等分规则，预设了 `5*12` 种 CSS 排列类，内置多种大小尺寸的多终端适配，能很好地实现响应式布局，这意味着一套系统，能同时适配于电脑的不同大小屏幕和手机、平板等移动屏幕，使得网页布局变得更加灵活，同时也极大地降低了 `HTML/CSS` 代码的耦合。

> 贴士：以下示例中的*背景色*仅仅只是为了让布局效果显得更加直观，实际使用时并不需要背景色。

<h2 id="container" lay-toc="">布局容器</h2>
|
|
|
|
|
|
将栅格放入一个带有 `class="layui-container"` 的特定容器中，以便在小屏幕以上的设备中固定宽度，让列可控。
|
|
|
|
|
|
```
|
|
|
<div class="layui-container">
|
|
|
<div class="layui-row">
|
|
|
……
|
|
|
</div>
|
|
|
</div>
|
|
|
```
|
|
|
|
|
|
当然，你还可以不固定容器宽度。将栅格或其它元素放入一个带有 `class="layui-fluid"`的容器中，那么宽度将不会固定，而是 100% 适应
|
|
|
|
|
|
```
|
|
|
<div class="layui-fluid">
|
|
|
……

</div>

下面是一个简单的例子，列间距为 `16px`：
|
|
|
|
|
|
```
|
|
|
<div class="layui-row layui-col-space16">
|
|
|
<div class="layui-col-md4">
|
|
|
1/3
|
|
|
</div>
|
|
|
<div class="layui-col-md4">
|
|
|
1/3
|
|
|
</div>
|
|
|
<div class="layui-col-md4">
|
|
|
1/3
|
|
|
</div>
|
|
|
</div>
|
|
|
```
|
|
|
|
|
|
<h2 id="offset" lay-toc="">列偏移</h2>
|
|
|
|
|
|
对列追加类似 `layui-col-md-offset*` 的预设类，从而让列向右偏移。如：`layui-col-md-offset3`，即代表在“中型桌面屏幕”下，让该列向右偏移 3 个列宽度。下面是一个采用「列偏移」机制让两个列左右对齐的实例
|
|
|
|
|
|
```
|
|
|
div class="layui-row">
|
|
|
<div class="layui-col-md4">
|
|
|
4/12
|
|
|
</div>
|
|
|
<div class="layui-col-md4 layui-col-md-offset4">
|
|
|
偏移4列，从而在最右
|
|
|
</div>
|
|
|
</div>
|
|
|
```
|
|
|
|
|
|
> 请注意，列偏移可针对不同屏幕的标准进行设定，比如上述的例子，只会在桌面屏幕下有效，当低于桌面屏幕的规定的临界值，就会堆叠排列。

<h2 id="iepatch" lay-toc="">IE8/9 兼容方案</h2>
|
|
|
|
|
|
事实上 `IE8/IE9` 并不支持 `Media Queries`，但你可以使用下面的补丁进行兼容（补丁来自于开源社区）：
|
|
|
|
|
|
```
|
|
|
<!-- 让 IE8/9 支持媒体查询，从而兼容栅格 -->
|
|
|
<!--[if lt IE 9]>

|
|
|
<![endif]-->
|
|
|
```
|
|
|
|
|
|
将上述代码放入你页面 `<body>` 标签内的任意位置即可。 |
