      如你所愿，在 layui 2.0 的版本中，我们加入了强劲的栅格系统和常见的管理系统布局方案，这意味着你可以采用 layui 排版你的响应式网站和后台管理系统的界面了。layui 的栅格采用业界比较常见的 12 等分规则，内置手机、平板、PC 桌面中大型屏幕的多终端适配处理，最低能支持到 ie8。而你应当更欣喜的是，layui 终于开放了它经典的管理系统布局方案，快速搭建一个属于你的管理系统将变得十分轻松自如。

                <ul>

                  <li>变量<em>*</em> 代表的是该列所占用的12等分数（如6/12），可选值为 1 - 12</li>
                  <li>如果多个列的“等分数值”总和等于12，则刚好满行排列。如果大于12，多余的列将自动另起一行。</li>

          <tr>
            <td>5.</td>

            <td>sm</td>
            <td>md</td>
            <td>lg</td>
          </tr>
          <tr>
            <td>列对应类<br>* 为1-12的等分数值</td>
            <td>layui-col-xs*</td>
            <td>layui-col-sm*</td>
            <td>layui-col-md*</td>
            <td>layui-col-lg*</td>
          </tr>
          <tr>
            <td>总列数</td>
            <td colspan="4">12</td>
          </tr>
          <tr>
            <td>响应行为</td>
            <td>始终按设定的比例水平排列</td>
            <td colspan="3">在当前屏幕下水平排列，如果屏幕大小低于临界值则堆叠排列</td>
          </tr>
        </tbody>
      </table>
      
      <a name="grid-class"></a>
      <br>
      <p>三、响应式公共类：</p>
      <hr>
       <table class="layui-table">
        <colgroup>
          <col width="150">
          <col>
        </colgroup>
        <thead>
          <tr>
            <th>类名（class）</th>
            <th>说明</th>
          </tr> 
        </thead>
        <tbody>
          <tr>
            <td>layui-show-*-block</td>
            <td class="layui-text">定义不同设备下的 display: block; * 可选值有：xs、sm、md、lg</td>
          </tr>
          <tr>
            <td>layui-show-*-inline</td>
            <td>定义不同设备下的 display: inline; * 可选值同上</td>
          </tr>
          <tr>
            <td>layui-show-*-inline-block</td>
            <td>定义不同设备下的 display: inline-block; * 可选值同上</td>
          </tr>
          <tr>
            <td>layui-hide-*</td>
            <td>定义不同设备下的隐藏类，即： display: none; * 可选值同上</td>
          </tr>
        </tbody>
      </table>
      
      <a name="grid-container"></a>
      <br>
      <p>四、布局容器：</p>
      <hr>
      <p>将栅格放入一个带有 <em>class="layui-container"</em> 的特定的容器中，以便在小屏幕以上的设备中固定宽度，让列可控。</p>
      <pre class="layui-code">
&lt;div class=&quot;layui-container&quot;&gt;
  &lt;div class=&quot;layui-row&quot;&gt;
    ……
  &lt;/div&gt;
&lt;/div&gt;      
      </pre>  
      <p>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 <em>class="layui-fluid"</em> 的容器中，那么宽度将不会固定，而是 100% 适应</p>
      <pre class="layui-code">
&lt;div class=&quot;layui-fluid&quot;&gt;
  ……
&lt;/div&gt;      
      </pre> 
      
      <a name="grid-space"></a>
      <br>
      <p>五、列间距：</p>
      <hr>
      <table class="layui-table">
        <colgroup>
          <col width="200">
          <col>
        </colgroup>
        <tbody>
          <tr>
            <td colspan="2">通过“列间距”的预设类，来设定列之间的间距。且一行中最左的列不会出现左边距，最右的列不会出现右边距。列间距在保证排版美观的同时，还可以进一步保证分列的宽度精细程度。我们结合网页常用的边距，预设了 12 种不同尺寸的边距，分别是：</td>
          </tr>
          <tr>
            <td>
              layui-col-space1
              <br>layui-col-space2
              <br>layui-col-space4
              <br>layui-col-space5
              <br>layui-col-space6
              <br>layui-col-space8
              <br>layui-col-space10
              <br>layui-col-space12
              <br>layui-col-space14
              <br>layui-col-space15
              <br>layui-col-space16
              <br>layui-col-space18
              <br>layui-col-space20
              <br>layui-col-space22
              <br>layui-col-space24
              <br>layui-col-space25
              <br>layui-col-space26
              <br>layui-col-space28
              <br>layui-col-space30
            </td>
            <td>支持列之间为 1px-30px 区间的所有双数间隔，以及 1px、5px、15px、25px 的单数间隔</td>
          </tr>
        </tbody>
      </table>
      <p>下面是一个简单的例子，列间距为10px：</p>
      <div class="layui-row layui-col-space10">
        <div class="layui-col-md4">
          <div class="grid-demo grid-demo-bg1">1/3</div>
        </div>
        <div class="layui-col-md4">
          <div class="grid-demo">1/3</div>
        </div>
        <div class="layui-col-md4">
          <div class="grid-demo grid-demo-bg1">1/3</div>
        </div>
      </div>
      <pre class="layui-code">
&lt;div class=&quot;layui-row layui-col-space10&quot;&gt;
  &lt;div class=&quot;layui-col-md4&quot;&gt;
    1/3
  &lt;/div&gt;
  &lt;div class=&quot;layui-col-md4&quot;&gt;
    1/3
  &lt;/div&gt;
  &lt;div class=&quot;layui-col-md4&quot;&gt;
    1/3
  &lt;/div&gt;
&lt;/div&gt;
      </pre>
      <p>如果需要的间距高于30px（一般不常见），请采用偏移，下文继续讲解</p>
      
      <a name="grid-offset"></a>
      <br>
      <p>六、列偏移：</p>
      <hr>
      <p>
        对列追加 类似 <em>layui-col-md-offset*</em> 的预设类，从而让列向右偏移。其中 <em>*</em> 号代表的是偏移占据的列数，可选中为 1 - 12。
        <br>如：<em>layui-col-md-offset3</em>，即代表在“中型桌面屏幕”下，让该列向右偏移 3 个列宽度
      </p>
      <p>下面是一个采用「列偏移」机制让两个列左右对齐的实例</p>
      <div class="layui-row">
        <div class="layui-col-md4">
          <div class="grid-demo grid-demo-bg1">4/12</div>
        </div>
        <div class="layui-col-md4 layui-col-md-offset4">
          <div class="grid-demo">偏移4列，从而在最右</div>
        </div>
      </div>
      <pre class="layui-code">
&lt;div class=&quot;layui-row&quot;&gt;
  &lt;div class=&quot;layui-col-md4&quot;&gt;
    4/12
  &lt;/div&gt;
  &lt;div class=&quot;layui-col-md4 layui-col-md-offset4&quot;&gt;
    偏移4列，从而在最右
  &lt;/div&gt;
&lt;/div&gt;
      </pre>
      <p>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。</p>
      
      <a name="grid-nesting"></a>
      <br>
      <p>七、栅格嵌套：</p>
      <hr>
      <p>理论上，你可以对栅格进行无穷层次的嵌套，这更加增强了栅格的表现能力。而嵌套的使用非常简单。在列元素（<em>layui-col-md*</em>）中插入一个行元素（<em>layui-row</em>），即可完成嵌套。下面是一个简单的例子：</p>
      <div class="layui-row layui-col-space5">
        <div class="layui-col-md5">
          <div class="layui-row grid-demo">
            <div class="layui-col-md3">
              <div class="grid-demo grid-demo-bg1">内部列</div>
            </div>
            <div class="layui-col-md9">
              <div class="grid-demo grid-demo-bg2">内部列</div>
            </div>
            <div class="layui-col-md12">
              <div class="grid-demo grid-demo-bg3">内部列</div>
            </div>
          </div>
        </div>
        <div class="layui-col-md7">
          <div class="layui-row grid-demo grid-demo-bg1">
            <div class="layui-col-md12">
              <div class="grid-demo">内部列</div>
            </div>
            <div class="layui-col-md9">
              <div class="grid-demo grid-demo-bg2">内部列</div>
            </div>
            <div class="layui-col-md3">
              <div class="grid-demo grid-demo-bg3">内部列</div>
            </div>
          </div>
        </div>
      </div>
      <pre class="layui-code">
&lt;div class=&quot;layui-row layui-col-space5&quot;&gt;
  &lt;div class=&quot;layui-col-md5&quot;&gt;
    &lt;div class=&quot;layui-row grid-demo&quot;&gt;
      &lt;div class=&quot;layui-col-md3&quot;&gt;
        内部列
      &lt;/div&gt;
      &lt;div class=&quot;layui-col-md9&quot;&gt;
        内部列
      &lt;/div&gt;
      &lt;div class=&quot;layui-col-md12&quot;&gt;
        内部列
      &lt;/div&gt;
    &lt;/div&gt;
  &lt;/div&gt;
  &lt;div class=&quot;layui-col-md7&quot;&gt;
    &lt;div class=&quot;layui-row grid-demo grid-demo-bg1&quot;&gt;
      &lt;div class=&quot;layui-col-md12&quot;&gt;
        内部列
      &lt;/div&gt;
      &lt;div class=&quot;layui-col-md9&quot;&gt;
        内部列
      &lt;/div&gt;
      &lt;div class=&quot;layui-col-md3&quot;&gt;
        内部列
      &lt;/div&gt;
    &lt;/div&gt;
  &lt;/div&gt;
&lt;/div&gt;
      </pre>
      <a name="grid-iepatch"></a>
      <br>
      <p>八、让IE8/9兼容栅格：</p>
      <hr>
      <p>事实上IE8和IE9并不支持媒体查询（Media Queries），但你可以使用下面的补丁完美兼容！该补丁来自于开源社区：</p>
      <pre class="layui-code">
&lt;!-- 让IE8/9支持媒体查询，从而兼容栅格 --&gt;
&lt;!--[if lt IE 9]&gt;
  &lt;script src=&quot;https://cdn.staticfile.org/html5shiv/r29/html5.min.js&quot;&gt;&lt;/script&gt;
  &lt;script src=&quot;https://cdn.staticfile.org/respond.js/1.4.2/respond.min.js&quot;&gt;&lt;/script&gt;
&lt;![endif]--&gt;
      </pre>
      <p>将上述代码放入你页面 <em>&lt;body&gt;</em> 标签内的任意位置</p>
    </div>
    
    
    <fieldset class="layui-elem-field layui-field-title site-title">
