Layout 布局

通过基础的 24 分栏，迅速简便地创建布局。

基础布局

使用单一分栏创建基础的栅格布局。

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

<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="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>

<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

分栏之间存在间隔。

:::demo 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。

:::demo

<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。

:::demo 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 布局来对分栏进行灵活的对齐。

:::demo 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。

:::demo

<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>

基于断点的隐藏类

Element 额外提供了一系列类名，用于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。如果需要，请自行引入以下文件：

import 'element-ui/lib/theme-chalk/display.css';

包含的类名及其含义为：

  • hidden-xs-only - 当视口在 xs 尺寸时隐藏
  • hidden-sm-only - 当视口在 sm 尺寸时隐藏
  • 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-only - 当视口在 md 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-only - 当视口在 lg 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
  • hidden-xl-only - 当视口在 xl 尺寸时隐藏
