  cn: `# 布局
  协助进行页面级整体布局。

## 设计规则

### 尺寸

一级导航项偏左靠近 logo 放置，辅助菜单偏右放置。

- 顶部导航（大部分系统）：一级导航高度 \`64px\`，二级导航 \`48px\`。
- 顶部导航（展示类页面）：一级导航高度 \`80px\`，二级导航 \`56px\`。
- 顶部导航高度的范围计算公式为：\`48+8n\`。
- 侧边导航宽度的范围计算公式：\`200+8n\`。

### 交互

- 一级导航和末级的导航需要在可视化的层面被强调出来；
- 当前项应该在呈现上优先级最高；
- 当导航收起的时候，当前项的样式自动赋予给它的上一个层级；
- 左侧导航栏的收放交互同时支持手风琴和全展开的样式，根据业务的要求进行适当的选择。

### 视觉

导航样式上需要根据信息层级合理的选择样式：

- **大色块强调**

  建议用于底色为深色系时，当前页面父级的导航项。

- **高亮火柴棍**

  当导航栏底色为浅色系时使用，可用于当前页面对应导航项，建议尽量在导航路径的最终项使用。

- **字体高亮变色**

  从可视化层面，字体高亮的视觉强化力度低于大色块，通常在当前项的上一级使用。

- **字体放大**

  \`12px\`、\`14px\` 是导航的标准字号，14 号字体用在一、二级导航中。字号可以考虑导航项的等级做相应选择。

## 组件概述

- \`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，自带默认样式，其下可嵌套任何元素，只能放在 \`Layout\` 中。
- \`Sider\`：侧边栏，自带默认样式及基本功能，其下可嵌套任何元素，只能放在 \`Layout\` 中。
- \`Content\`：内容部分，自带默认样式，其下可嵌套任何元素，只能放在 \`Layout\` 中。
- \`Footer\`：底部布局，自带默认样式，其下可嵌套任何元素，只能放在 \`Layout\` 中。

        ## 代码演示`,
  us: `# Layout
  Handling the overall layout of a page.

## Specification

### Size

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

- Top Navigation (almost systems): the height of the first level navigation \`64px\`, the second level navigation \`48px\`.
- Top Navigation(contents page): the height of the first level navigation \`80px\`, the second level navigation \`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 distincted by visualization;
- The current item should have the highest priority of visualization;
- When the current navigation item is collapsed, the stlye of the current navigation item will be 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 best.

## Visualization rules

 Style of a navigation should conform to its level.

- **Emphasis by colorblock**

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

- **The highlight match stick**

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

- **Hightlighted font**

  From the visualization aspect, hightlighted 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 navigations，\`14px\` is used for the first and the second level of the navigation. You can choose a appropriate font size in terms of 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 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 default style, in which any element can be nested, and must be placed in \`Layout\`.
- \`Footer\`: The bottom layout with 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).
