--- layout: docs title: Navs description: Documentation and examples for how to use Bootstrap's included navigation components. group: components --- 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. ## Contents * Will be replaced with the ToC, excluding the "Contents" header {:toc} ## Regarding accessibility 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 `

{% endexample %} ### Stacked pills Add `.nav-stacked` to the `.nav.nav-pills` to stack them vertically. Each `.nav-link` becomes block-level, allowing for larger hit areas via mouse or tap. {% example html %}
