Layout 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。

注意：采用 flex 布局实现，请注意浏览器兼容性问题。

上中下布局

最基本的『上-中-下』布局。
一般主导航放置于页面的顶端，从左自右依次为：logo、一级导航项、辅助菜单（用户、设置、通知等）。通常将内容放在固定尺寸（例如：1200px）内，整个页面排版稳定，不受用户终端显示器影响；上下级的结构符合用户上下浏览的习惯，也是较为经典的网站导航模式。页面上下切分的方式提高了主工作区域的信息展示效率，但在纵向空间上会有一些牺牲。此外，由于导航栏水平空间的限制，不适合那些一级导航项很多的信息结构。

侧边布局

侧边两列式布局。页面横向空间有限时，侧边导航可收起。
侧边导航在页面布局上采用的是左右的结构，一般主导航放置于页面的左侧固定位置，辅助菜单放置于工作区顶部。内容根据浏览器终端进行自适应，能提高横向空间的使用率，但是整个页面排版不稳定。侧边导航的模式层级扩展性强，一、二、三级导航项目可以更为顺畅且具关联性的被展示，同时侧边导航可以固定，使得用户在操作和浏览中可以快速的定位和切换当前位置，有很高的操作效率。但这类导航横向页面内容的空间会被牺牲一部份。

自定义触发器

要使用自定义触发器，可以设置 :trigger="null" 来隐藏默认设定。

                                <template>
  <a-layout>
    <a-layout-sider v-model:collapsed="collapsed" :trigger="null" collapsible>

响应式布局

Layout.Sider 支持响应式布局。

说明：配置 breakpoint 属性即生效，视窗宽度小于 breakpoint 时 Sider 缩小为 collapsedWidth 宽度，若将 collapsedWidth 设置为零，会出现特殊 trigger。

固定侧边栏

当内容较长时，使用固定侧边栏可以提供更好的体验。
