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。
