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。

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。

::: 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。

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。

::: demo

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。

::: demo 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。

::: 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。

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：xs、sm、md和lg。

::: demo

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>
  )
}
