布局特性

总共24列
组件el-row声明行，默认渲染为div，通过tag属性来声明渲染成的标签
组件el-col声明列，默认渲染为div，通过tag属性来声明渲染成的标签
通过组件el-col中的span属性来指定列数
- :span="24"
通过组件el-row中的gutter属性来指定列之间的间隔
- :gutter: "50"，表示padding-left: 25px; padding-right: 25px;
通过组件el-col中的offset属性来指定列偏移量
- :offset="8"
通过组件el-col中的push | pull属性来指定列排序，存在覆盖现象
- :push="6"，表示往右移动6列
- :pull="6"，表示往左移动6列
通过组件el-row中的type属性来开启flex弹性布局，type="flex"
- 并且通过justify属性来指定子元素排版方式
  - justify="start | end | center | space-between | space-around"
- 以及通过align属性来指定子元素的垂直排版方式
  - align="top | bottom | middle"
通过组件el-col中的xs | sm | md | lg | xl属性进行响应式布局
- xs < 768px
- sm >= 768px
- md >= 992px
- lg >= 1200px
- xl >= 1920px
通过引入import 'element-ui/lib/theme-chalk/display.css';可在某些条件下隐藏元素
- 这些类名可以添加在任何 DOM 元素或自定义组件上
  - .hidden-xs-only 当视口在xs时隐藏
  - .hidden-sm-only 当视口在sm时隐藏
  - .hidden-md-only 当视口在md时隐藏
  - .hidden-lg-only 当视口在lg时隐藏
  - .hidden-xl-only 当视口在xl时隐藏
  - .hidden-sm-and-down 当视口在sm及以下尺寸时隐藏
  - .hidden-sm-and-up 当视口在sm及以上尺寸时隐藏
  - .hidden-md-and-down 当视口在md及以下尺寸时隐藏
  - .hidden-md-and-up 当视口在md及以上尺寸时隐藏
  - .hidden-lg-and-down 当视口在lg及以下尺寸时隐藏
  - .hidden-lg-and-up 当视口在lg及以上尺寸时隐藏

测试用的CSS代码


 .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;
  }

基础布局

通过el-row和el-col 组件，并通过el-col 组件的 span属性我们就可以自由地组合布局。

<el-row tag="section">
  <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="12"><div class="grid-content bg-purple-light"></div></el-col>
</el-row>
<el-row>
  <el-col :span="8"><div class="grid-content bg-purple"></div></el-col>
  <el-col :span="8"><div class="grid-content bg-purple-light"></div></el-col>
  <el-col :span="8"><div class="grid-content bg-purple"></div></el-col>
</el-row>
<el-row>
  <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-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>

分栏间隔(gutter)

el-ow 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>

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>

分栏偏移

通过制定 el-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>

分栏排序

通过组件el-col中的push| pull属性来指定列排序，存在覆盖现象

<h1>列排序</h1>
<el-row :gutter="20">
  <el-col :span="6" :push="6"><div class="grid-content bg-purple">push 6</div></el-col>
  <el-col :span="6" :pull="6"><div class="grid-content bg-purple">pull 6</div></el-col>
</el-row>

flex布局

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>

响应式布局

<h1>响应式布局</h1>
<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="{span: 4, offset: 4}" :sm="6" :md="4" :lg="3" :xl="1"><div class="grid-content bg-purple-light"></div></el-col>
</el-row>
