Navs
navs.less
Navs available in Bootstrap have shared markup, starting with the base .nav
class, as well as shared states. Swap modifier classes to switch between
each style.
Using navs for tab panels requires JavaScript tabs plugin
For tabs with tabbable areas, you must use the tabs JavaScript plugin. The markup will also require additional role and ARIA attributes – see the plugin's example markup for further details.
Make navs used as navigation accessible
If you are using navs to provide a navigation bar, be sure to add a
role="navigation" to the most logical parent container of the <ul>, or
wrap a <nav> element around the whole navigation. Do not add the role to
the <ul> itself, as this would prevent it from being announced as an actual
list by assistive technologies.
Tabs
Note the .nav-tabs class requires the .nav base class.
Pills
Take that same HTML, but use .nav-pills instead:
Pills are also vertically stackable. Just add .nav-stacked.
Justified
Easily make tabs or pills equal widths of their parent at screens wider than
768px with .nav-justified. On smaller screens, the nav links are stacked.
Justified navbar nav links are currently not supported.
Safari and responsive justified navs
As of v8.0, Safari exhibits a bug in which resizing your browser horizontally causes rendering errors in the justified nav that are cleared upon refreshing. This bug is also shown in the justified nav example.
Disabled Links
For any nav component (tabs or pills), add .disabled for gray links and
no hover effects.
Link functionality not impacted
This class will only change the <a>'s appearance, not its functionality.
Use custom JavaScript to disable links here.
Using Dropdowns
Add dropdown menus with a little extra HTML and the dropdowns JavaScript plugin.
