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

    12px14px 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 FooterLayout 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。

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。

同样拥有顶部导航及侧边栏,区别是两边未留边距,多用于应用型的网站。

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分。
