Handling the overall layout of a page.


## Specification

### Size

The first level navigation is left aligned near a logo, and the secondary menu is right aligned.

- Top Navigation: the height of the first level navigation is `64px`, and the second level navigation is `48px`.
- Top Navigation (for landing pages): the height of the first level navigation is `80px`, and the second level navigation is `56px`.
- Calculation formula of a top navigation: `48+8n`.
- Calculation formula of an aside navigation: `200+8n`.

### Interaction rules

- The first level navigation and the last level navigation should be distinguishable by visualization;
- The current item should have the highest priority of visualization;
- When the current navigation item is collapsed, the style of the current navigation item is applied to its parent level;
- The left side navigation bar has support for both the accordion and expanding styles; you can choose the one that fits your case the best.

## Visualization rules

Style of a navigation should conform to its level.

- **Emphasis by colorblock**

  When the background color is a deep color, you can use this pattern for the parent level navigation item of the current page.

- **The highlight match stick**

  When the background color is a light color, you can use this pattern for the current page navigation item; we recommend using it for the last item of the navigation path.

- **Highlighted font**

  From the visualization aspect, a highlighted font is stronger than colorblock; this pattern is often used for the parent level of the current item.

- **Enlarge the size of the font**

  `12px`, `14px` is a standard font size of navigation's, `14px` is used for the first and the second level of the navigation. You can choose an appropriate font size regarding the level of your navigation.

## Component Overview

- `Layout`: The layout wrapper, in which `Header` `Sider` `Content` `Footer` or `Layout` itself can be nested, and can be placed in any parent container.
- `Header`: The top layout with the default style, in which any element can be nested, and must be placed in `Layout`.
- `Sider`: The sidebar with default style and basic functions, in which any element can be nested, and must be placed in `Layout`.
- `Content`: The content layout with the default style, in which any element can be nested, and must be placed in `Layout`.
- `Footer`: The bottom layout with the default style, in which any element can be nested, and must be placed in `Layout`.

> Based on `flex layout`, please pay attention to the [compatibility](http://caniuse.com/#search=flex).

## Shared native props {#jguang-common-props}


> Tips: The following generic properties apply to most antd components; those not supported are described separately.

| Property | Description | Type | Default |
| --- | --- | --- | --- |
| style | The additional style | CSSProperties | - |
| className | The additional css class | string | - |
| rootClassName | ClassName on the root element | string | - |

## Install and reproduce an example

```bash
npm install antd@6.6.5 @ant-design/icons@6.3.4 dayjs@1.11.23
```

Use ConfigProvider and native App; configure dayjs locale separately. Each example lists its complete source files and additional pinned dependencies in View code. Example names select demos, not universal component props. See the resource setup guide for theme, locale and SSR.
