<el-row>
  <el-col :span="24"><div class="grid-content bg-purple-dark"></div></el-col>
</el-row>
<el-row>
  <el-col :span="12"><div class="grid-content bg-purple"></div></el-col>

  <el-col :span="6"><div class="grid-content bg-purple-light"></div></el-col>
  <el-col :span="6"><div class="grid-content bg-purple"></div></el-col>
  <el-col :span="6"><div class="grid-content bg-purple-light"></div></el-col>
</el-row>
<el-row>
  <el-col :span="4"><div class="grid-content bg-purple"></div></el-col>
  <el-col :span="4"><div class="grid-content bg-purple-light"></div></el-col>
  <el-col :span="4"><div class="grid-content bg-purple"></div></el-col>
  <el-col :span="4"><div class="grid-content bg-purple-light"></div></el-col>
  <el-col :span="4"><div class="grid-content bg-purple"></div></el-col>
  <el-col :span="4"><div class="grid-content bg-purple-light"></div></el-col>
</el-row>

<style>
  .el-row {
    margin-bottom: 20px;
    &:last-child {
      margin-bottom: 0;
    }
  }
  .el-col {
    border-radius: 4px;
  }
  .bg-purple-dark {
    background: #99a9bf;
  }
  .bg-purple {
    background: #d3dce6;
  }
  .bg-purple-light {
    background: #e5e9f2;
  }
  .grid-content {
    border-radius: 4px;
    min-height: 36px;
  }
  .row-bg {
    padding: 10px 0;
    background-color: #f9fafc;
  }
</style>

分栏间隔
Row组件提供gutter属性来指定每一栏之间的间隔，默认间隔为0.

<el-row :gutter="20">
  <el-col :span="6"><div class="grid-content bg-purple"></div></el-col>
  <el-col :span="6"><div class="grid-content bg-purple"></div></el-col>
  <el-col :span="6"><div class="grid-content bg-purple"></div></el-col>
  <el-col :span="6"><div class="grid-content bg-purple"></div></el-col>
</el-row>

<style>
  .el-row {
    margin-bottom: 20px;
    &:last-child {
      margin-bottom: 0;
    }
  }
  .el-col {
    border-radius: 4px;
  }
  .bg-purple-dark {
    background: #99a9bf;
  }
  .bg-purple {
    background: #d3dce6;
  }
  .bg-purple-light {
    background: #e5e9f2;
  }
  .grid-content {
    border-radius: 4px;
    min-height: 36px;
  }
  .row-bg {
    padding: 10px 0;
    background-color: #f9fafc;
  }
</style>

混合布局
通过基础的1/24分栏任意扩展组合形成较为复杂的混合布局。

<el-row :gutter="20">
  <el-col :span="16"><div class="grid-content bg-purple"></div></el-col>
  <el-col :span="8"><div class="grid-content bg-purple"></div></el-col>
</el-row>
<el-row :gutter="20">
  <el-col :span="8"><div class="grid-content bg-purple"></div></el-col>
  <el-col :span="8"><div class="grid-content bg-purple"></div></el-col>
  <el-col :span="4"><div class="grid-content bg-purple"></div></el-col>
  <el-col :span="4"><div class="grid-content bg-purple"></div></el-col>
</el-row>
<el-row :gutter="20">
  <el-col :span="4"><div class="grid-content bg-purple"></div></el-col>
  <el-col :span="16"><div class="grid-content bg-purple"></div></el-col>
  <el-col :span="4"><div class="grid-content bg-purple"></div></el-col>
</el-row>

<style>
  .el-row {
    margin-bottom: 20px;
    &:last-child {
      margin-bottom: 0;
    }
  }
  .el-col {
    border-radius: 4px;
  }
  .bg-purple-dark {
    background: #99a9bf;
  }
  .bg-purple {
    background: #d3dce6;
  }
  .bg-purple-light {
    background: #e5e9f2;
  }
  .grid-content {
    border-radius: 4px;
    min-height: 36px;
  }
  .row-bg {
    padding: 10px 0;
    background-color: #f9fafc;
  }
</style>

分栏偏移（支持偏移指定的栏数）
通过制定col组件的offset属性可以指定分栏偏移的栏数。

<el-row :gutter="20">
  <el-col :span="6"><div class="grid-content bg-purple"></div></el-col>
  <el-col :span="6" :offset="6"><div class="grid-content bg-purple"></div></el-col>
</el-row>
<el-row :gutter="20">
  <el-col :span="6" :offset="6"><div class="grid-content bg-purple"></div></el-col>
  <el-col :span="6" :offset="6"><div class="grid-content bg-purple"></div></el-col>
</el-row>
<el-row :gutter="20">
  <el-col :span="12" :offset="6"><div class="grid-content bg-purple"></div></el-col>
</el-row>

<style>
  .el-row {
    margin-bottom: 20px;
    &:last-child {
      margin-bottom: 0;
    }
  }
  .el-col {
    border-radius: 4px;
  }
  .bg-purple-dark {
    background: #99a9bf;
  }
  .bg-purple {
    background: #d3dce6;
  }
  .bg-purple-light {
    background: #e5e9f2;
  }
  .grid-content {
    border-radius: 4px;
    min-height: 36px;
  }
  .row-bg {
    padding: 10px 0;
    background-color: #f9fafc;
  }
</style>

对齐方式
通过flex布局对分栏进行灵活的对齐
将 type 属性赋值为 ‘flex’，可以启用 flex 布局，并可通过 justify 属性来指定 start, center, end, space-between, space-around 其中的值来定义子元素的排版方式。

<el-row type="flex" class="row-bg">
  <el-col :span="6"><div class="grid-content bg-purple"></div></el-col>
  <el-col :span="6"><div class="grid-content bg-purple-light"></div></el-col>
  <el-col :span="6"><div class="grid-content bg-purple"></div></el-col>
</el-row>
<el-row type="flex" class="row-bg" justify="center">
  <el-col :span="6"><div class="grid-content bg-purple"></div></el-col>
  <el-col :span="6"><div class="grid-content bg-purple-light"></div></el-col>
  <el-col :span="6"><div class="grid-content bg-purple"></div></el-col>
</el-row>
<el-row type="flex" class="row-bg" justify="end">
  <el-col :span="6"><div class="grid-content bg-purple"></div></el-col>
  <el-col :span="6"><div class="grid-content bg-purple-light"></div></el-col>
  <el-col :span="6"><div class="grid-content bg-purple"></div></el-col>
</el-row>
<el-row type="flex" class="row-bg" justify="space-between">
  <el-col :span="6"><div class="grid-content bg-purple"></div></el-col>
  <el-col :span="6"><div class="grid-content bg-purple-light"></div></el-col>
  <el-col :span="6"><div class="grid-content bg-purple"></div></el-col>
</el-row>
<el-row type="flex" class="row-bg" justify="space-around">
  <el-col :span="6"><div class="grid-content bg-purple"></div></el-col>
  <el-col :span="6"><div class="grid-content bg-purple-light"></div></el-col>
  <el-col :span="6"><div class="grid-content bg-purple"></div></el-col>
</el-row>

<style>
  .el-row {
    margin-bottom: 20px;
    &:last-child {
      margin-bottom: 0;
    }
  }
  .el-col {
    border-radius: 4px;
  }
  .bg-purple-dark {
    background: #99a9bf;
  }
  .bg-purple {
    background: #d3dce6;
  }
  .bg-purple-light {
    background: #e5e9f2;
  }
  .grid-content {
    border-radius: 4px;
    min-height: 36px;
  }
  .row-bg {
    padding: 10px 0;
    background-color: #f9fafc;
  }
</style>

响应式布局
参照了 Bootstrap 的 响应式设计，预设了五个响应尺寸：xs、sm、md、lg 和 xl。

<el-row :gutter="10">
  <el-col :xs="8" :sm="6" :md="4" :lg="3" :xl="1"><div class="grid-content bg-purple"></div></el-col>
  <el-col :xs="4" :sm="6" :md="8" :lg="9" :xl="11"><div class="grid-content bg-purple-light"></div></el-col>
  <el-col :xs="4" :sm="6" :md="8" :lg="9" :xl="11"><div class="grid-content bg-purple"></div></el-col>
  <el-col :xs="8" :sm="6" :md="4" :lg="3" :xl="1"><div class="grid-content bg-purple-light"></div></el-col>
</el-row>

<style>
  .el-col {
    border-radius: 4px;
  }
  .bg-purple-dark {
    background: #99a9bf;
  }
  .bg-purple {
    background: #d3dce6;
  }
  .bg-purple-light {
    background: #e5e9f2;
  }
  .grid-content {
    border-radius: 4px;
    min-height: 36px;
  }
</style>

2.container布局容器
用于布局的容器组件，方便快速搭建页面的基本结构：
：外层容器。当子元素中包含 或 时，全部子元素会垂直上下排列，否则会水平左右排列。
：顶栏容器。
：侧边栏容器。
：主要区域容器。
：底栏容器。
以上组件采用了 flex 布局，使用前请确定目标浏览器是否兼容。此外， 的子元素只能是后四者，后四者的父元素也只能是 。
