The base .nav component does not include any .active state. The following examples include the class, mainly to demonstrate that this particular class does not trigger any special styling.

Navigation available in Bootstrap share general markup and styles, from the base .nav class to the active and disabled states. Swap modifier classes to switch between each style. The base .nav component is built with flexbox and provide a strong foundation for building all types of navigation components. It includes some style overrides (for working with lists), some link padding for larger hit areas, and basic disabled styling.

Classes are used throughout, so your markup can be super flexible. Use < ul >s like above, or roll your own with say a < nav > element. Because the .nav uses display: flex, the nav links behave the same as nav items would, but without the extra markup.

Change the horizontal alignment of your nav with flexbox utilities. By default, navs are left-aligned, but you can easily change them to center or right aligned. Centered with .justify-content-center

Right aligned with .justify-content-end

Takes the basic nav from above and adds the .nav-tabs class to generate a tabbed interface. Use them to create tabbable regions with our tab JavaScript plugin.

Stack your navigation by changing the flex item direction with the .flex-column utility. Need to stack them on some viewports but not others? Use the responsive versions (e.g., .flex-sm-column).

As always, vertical navigation is possible without < ul >s, too.

Force your .nav’s contents to extend the full available width one of two modifier classes. To proportionately fill all available space with your .nav-items, use .nav-fill. Notice that all horizontal space is occupied, but not every nav item has the same width.

When using a < nav >-based navigation, be sure to include .nav-item on the anchors.

For equal-width elements, use .nav-justified. All horizontal space will be occupied by nav links, but unlike the .nav-fill above, every nav item will be the same width.

Similar to the .nav-fill example using a < nav >-based navigation, be sure to include .nav-item on the anchors.

Take that same HTML, but use .nav-pills instead.
