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。

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。

render() {
return (
<div>
<Layout.Row>
<Layout.Col span="24"><div className="grid-content bg-purple-dark"></div></Layout.Col>
</Layout.Row>
<Layout.Row>
<Layout.Col span="12"><div className="grid-content bg-purple"></div></Layout.Col>
<Layout.Col span="12"><div className="grid-content bg-purple-light"></div></Layout.Col>
</Layout.Row>
<Layout.Row>
<Layout.Col span="8"><div className="grid-content bg-purple"></div></Layout.Col>
<Layout.Col span="8"><div className="grid-content bg-purple-light"></div></Layout.Col>
<Layout.Col span="8"><div className="grid-content bg-purple"></div></Layout.Col>
</Layout.Row>
<Layout.Row>
<Layout.Col span="6"><div className="grid-content bg-purple"></div></Layout.Col>
<Layout.Col span="6"><div className="grid-content bg-purple-light"></div></Layout.Col>
<Layout.Col span="6"><div className="grid-content bg-purple"></div></Layout.Col>
<Layout.Col span="6"><div className="grid-content bg-purple-light"></div></Layout.Col>
</Layout.Row>
<Layout.Row>
<Layout.Col span="4"><div className="grid-content bg-purple"></div></Layout.Col>
<Layout.Col span="4"><div className="grid-content bg-purple-light"></div></Layout.Col>
<Layout.Col span="4"><div className="grid-content bg-purple"></div></Layout.Col>
<Layout.Col span="4"><div className="grid-content bg-purple-light"></div></Layout.Col>
<Layout.Col span="4"><div className="grid-content bg-purple"></div></Layout.Col>
<Layout.Col span="4"><div className="grid-content bg-purple-light"></div></Layout.Col>
</Layout.Row>
</div>
)
}

分栏间隔

分栏之间存在间隔。

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。

render() {
return (
<Layout.Row gutter="20">
<Layout.Col span="6"><div className="grid-content bg-purple"></div></Layout.Col>
<Layout.Col span="6"><div className="grid-content bg-purple"></div></Layout.Col>
<Layout.Col span="6"><div className="grid-content bg-purple"></div></Layout.Col>
<Layout.Col span="6"><div className="grid-content bg-purple"></div></Layout.Col>
</Layout.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。

render() {
return (
<div>
<Layout.Row gutter="20">
<Layout.Col span="16"><div className="grid-content bg-purple"></div></Layout.Col>
<Layout.Col span="8"><div className="grid-content bg-purple"></div></Layout.Col>
</Layout.Row>
<Layout.Row gutter="20">
<Layout.Col span="8"><div className="grid-content bg-purple"></div></Layout.Col>
<Layout.Col span="8"><div className="grid-content bg-purple"></div></Layout.Col>
<Layout.Col span="4"><div className="grid-content bg-purple"></div></Layout.Col>
<Layout.Col span="4"><div className="grid-content bg-purple"></div></Layout.Col>
</Layout.Row>
<Layout.Row gutter="20">
<Layout.Col span="4"><div className="grid-content bg-purple"></div></Layout.Col>
<Layout.Col span="16"><div className="grid-content bg-purple"></div></Layout.Col>
<Layout.Col span="4"><div className="grid-content bg-purple"></div></Layout.Col>
</Layout.Row>
</div>
)
}

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。

render() {
return (
<div>
<Layout.Row gutter="20">
<Layout.Col span="6"><div className="grid-content bg-purple"></div></Layout.Col>
<Layout.Col span="6" offset="6"><div className="grid-content bg-purple"></div></Layout.Col>
</Layout.Row>
<Layout.Row gutter="20">
<Layout.Col span="6" offset="6"><div className="grid-content bg-purple"></div></Layout.Col>
<Layout.Col span="6" offset="6"><div className="grid-content bg-purple"></div></Layout.Col>
</Layout.Row>
<Layout.Row gutter="20">
<Layout.Col span="12" offset="6"><div className="grid-content bg-purple"></div></Layout.Col>
</Layout.Row>
</div>
)
}

对齐方式

对分栏进行灵活的对齐。

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。

render() {
return (
<div>
<Layout.Row type="flex" className="row-bg">
<Layout.Col span="6"><div className="grid-content bg-purple"></div></Layout.Col>
<Layout.Col span="6"><div className="grid-content bg-purple-light"></div></Layout.Col>
<Layout.Col span="6"><div className="grid-content bg-purple"></div></Layout.Col>
</Layout.Row>
<Layout.Row type="flex" className="row-bg" justify="center">
<Layout.Col span="6"><div className="grid-content bg-purple"></div></Layout.Col>
<Layout.Col span="6"><div className="grid-content bg-purple-light"></div></Layout.Col>
<Layout.Col span="6"><div className="grid-content bg-purple"></div></Layout.Col>
</Layout.Row>
<Layout.Row type="flex" className="row-bg" justify="end">
<Layout.Col span="6"><div className="grid-content bg-purple"></div></Layout.Col>
<Layout.Col span="6"><div className="grid-content bg-purple-light"></div></Layout.Col>
<Layout.Col span="6"><div className="grid-content bg-purple"></div></Layout.Col>
</Layout.Row>
<Layout.Row type="flex" className="row-bg" justify="space-between">
<Layout.Col span="6"><div className="grid-content bg-purple"></div></Layout.Col>
<Layout.Col span="6"><div className="grid-content bg-purple-light"></div></Layout.Col>
<Layout.Col span="6"><div className="grid-content bg-purple"></div></Layout.Col>
</Layout.Row>
<Layout.Row type="flex" className="row-bg" justify="space-around">
<Layout.Col span="6"><div className="grid-content bg-purple"></div></Layout.Col>
<Layout.Col span="6"><div className="grid-content bg-purple-light"></div></Layout.Col>
<Layout.Col span={6}><div className="grid-content bg-purple"></div></Layout.Col>
</Layout.Row>
</div>
)
}

响应式布局

参照了 Bootstrap 的 响应式设计,预设了四个响应尺寸:xssmmdlg

render() {
return (
<Layout.Row gutter="10">
<Layout.Col xs="8" sm="6" md="4" lg="3"><div className="grid-content bg-purple"></div></Layout.Col>
<Layout.Col xs="4" sm="6" md="8" lg="9"><div className="grid-content bg-purple-light"></div></Layout.Col>
<Layout.Col xs="4" sm="6" md="8" lg="9"><div className="grid-content bg-purple"></div></Layout.Col>
<Layout.Col xs="8" sm="6" md="4" lg="3"><div className="grid-content bg-purple-light"></div></Layout.Col>
</Layout.Row>
)
}

基于断点的隐藏类

Element Plus 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-plus/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
