Documentation and examples for Bootstrap’s powerful, responsive navigation header, the navbar. Includes support for branding, navigation, and more, including support for our collapse plugin.
Navbars come with built-in support for a handful of sub-components. Choose from the following as needed:
.navbar-brandfor your company, product, or project name.
.navbar-navfor a full-height and lightweight navigation (including support for dropdowns).
.navbar-togglerfor use with our collapse plugin and other navigation toggling behaviors.
.navbar-textfor adding vertically centered strings of text.
.collapse.navbar-collapsefor grouping and hiding navbar contents by a parent breakpoint.
.navbar-scrollto set a
max-heightand scroll expanded navbar content.
Here’s an example of all the sub-components included in a responsive light-themed navbar that automatically collapses at the
lg (large) breakpoint.

You can also use dropdowns in your navbar. Dropdown menus require a wrapping element for positioning, so be sure to use separate and nested elements for .nav-item and .nav-link as shown below.
Theming the navbar has never been easier thanks to the combination of theming classes and
background-color utilities. Choose from
.navbar-light for use with light background colors, or
.navbar-dark for dark background colors. Then, customize with
.navbar-nav-scroll to a
.navbar-nav (or other navbar sub-component) to enable vertical scrolling within the toggleable contents of a collapsed navbar. By default, scrolling kicks in at
75vh (or 75% of the viewport height), but you can override that with the local CSS custom property
--bs-navbar-height or custom styles. At larger viewports when the navbar is expanded, content will appear as it does in a default navbar.
Please note that this behavior comes with a potential drawback of
overflow-y: auto (required to scroll the content here),
overflow-x is the equivalent of
auto, which will crop some horizontal content.
Here’s an example navbar using
style="--bs-scroll-height: 100px;", with some extra margin utilities for optimum spacing.
Navbar togglers are left-aligned by default, but should they follow a sibling element like a
.navbar-brand, they’ll automatically be aligned to the far right. Reversing your markup will reverse the placement of the toggler. Below are examples of different toggle styles.

id of the content container. In theory, this allows assistive technology users to jump directly from the toggler to the container it controls–but support for this is currently quite patchy.
