brief: 用于快捷划分页面整体布局

概述

  • Layout：布局容器，其下可嵌套 Header Sider Content Footer 或 Layout 本身，可以放在任何父容器中。
  • Header：顶部布局，其下可嵌套任何元素，只能放在 Layout 中。
  • Sider：侧边栏，其下可嵌套任何元素，只能放在 Layout 中。
  • Content：内容部分，其下可嵌套任何元素，只能放在 Layout 中。
  • Footer：底部布局，其下可嵌套任何元素，只能放在 Layout 中。

1、布局组件采用 Flex 布局实现，无法在非现代浏览器中工作
2、Layout 组件仅会帮你实现布局，但不会附带背景色、文本色、宽高度等样式。你可以根据自己实际需求传入 style 或给定特定 className 另行编写css实现

代码演示

如何引入

import { Layout } from '@douyinfe/semi-ui';

三行布局

import React from 'react';
import { Layout } from '@douyinfe/semi-ui';

() => {
    const { Header, Footer, Content } = Layout;

    return (
        <Layout className="components-layout-demo">
            <Header>Header</Header>
            <Content>Content</Content>
            <Footer>Footer</Footer>
        </Layout>
    );
};

左侧边栏布局

import React from 'react';
import { Layout } from '@douyinfe/semi-ui';

() => {
    const { Header, Footer, Sider, Content } = Layout;
    return (
        <Layout className="components-layout-demo">
            <Header>Header</Header>
            <Layout>
                <Sider>Sider</Sider>
                <Content>Content</Content>
            </Layout>
            <Footer>Footer</Footer>
        </Layout>
    );
};

右侧边栏布局

import React from 'react';
import { Layout } from '@douyinfe/semi-ui';

() => {
    const { Header, Footer, Sider, Content } = Layout;
    return (
        <Layout className="components-layout-demo">
            <Header>Header</Header>
            <Layout>
                <Content>Content</Content>
                <Sider>Sider</Sider>
            </Layout>
            <Footer>Footer</Footer>
        </Layout>
    );
};

侧边栏布局

import React from 'react';
import { Layout } from '@douyinfe/semi-ui';

() => {
    const { Header, Footer, Sider, Content } = Layout;
    return (
        <Layout className="components-layout-demo">
            <Sider>Sider</Sider>
            <Layout>
                <Header>Header</Header>
                <Content>Content</Content>
                <Footer>Footer</Footer>
            </Layout>
        </Layout>
    );
};

响应式布局

侧边栏预设了六个响应尺寸：xs、sm、md、lg、xl、xxl。可以通过设置 breakpoint 属性设置断点，通过 onBreakpoint 调用回调函数。

import React from 'react';
import { Layout } from '@douyinfe/semi-ui';

() => {
    const onbreakpoint = (screen, bool) => {
        console.log(screen, bool);
    };
    const { Header, Footer, Sider, Content } = Layout;
    return (
        <Layout className="components-layout-demo">
            <Header>Header</Header>
            <Layout>
                <Sider breakpoint={['md']} onBreakpoint={onbreakpoint}>
                    Sider
                </Sider>
                <Content>Content</Content>
            </Layout>
            <Footer>Footer</Footer>
        </Layout>
    );
};

布局示例

顶部导航布局

    const { Header, Footer, Content } = Layout;
    return (
