Navbar
Create a navigation header, with support for responsive layout, branding, navigation links and more.
Overview
The navbar is a simple wrapper for positioning branding, navigation, and other elements into a concise navigation header. It's easily extensible and, with the help of our Collapse widget.
Basics
Here's what you need to know before getting started with the navbar:
- Navbars require a wrapping
.navbar
, with.navbar-expand{-sm|-md|-lg|-xl}
for responsive collapsing, and color scheme classes. - Navbars and their contents are fluid by default. Use optional containers to limit their horizontal width.
- Navbars and their contents are built with flexbox, providing easy alignment options via flexbox utility and margin utility classes.
- Navbars are responsive by default, but you can easily modify them to change that. Responsive behavior depends on our Collapse widget.
- Ensure accessibility by using a
<nav>
element or, if using a more generic element such as a<div>
, add arole="navigation"
to every navbar to explicitly identify it as a landmark region for users of assistive technologies. - Indicate the current item by using
aria-current="page"
for the current page oraria-current="true"
for the current item in a set.
Responsive Behaviors
Navbars are built with responsive design in mind. Using a .navbar-expand{-sm|-md|-lg|-xl}
on the .navbar
along with a .navbar-collapse
container.
The following list gives a quick run-down of how the breakpoints are utilized.
- No modifier, just
.navbar
, is never expanded .navbar-expand
is always expanded.navbar-expand-sm
expands atsm
and up.navbar-expand-md
expands atmd
and up.navbar-expand-lg
expands atlg
and up.navbar-expand-xl
expands atxl
and up
Please refer to how our breakpoint nomenclature is used.
For the examples throughout this page, you will need to resize your browser window below/above the lg
breakpoint to see the navbars switch between modes.
Never Expand
The most basic example of a .navbar
is one that never expands, no matter the screen width.
<nav class="navbar navbar-light bg-light">
<button class="navbar-toggle" type="button" data-cfw="collapse" data-cfw-collapse-target="#navbarB0">
<span aria-hidden="true">≡</span>
</button>
<a href="#" class="navbar-brand ms-0_5">Never Expand</a>
<div class="navbar-collapse collapse" id="navbarB0">
<ul class="navbar-nav">
<li class="nav-item">
<a href="#" class="nav-link active" aria-current="page">Home</a>
</li>
<li class="nav-item">
<a href="#" class="nav-link">Link</a>
</li>
<li class="nav-item">
<a href="#" class="nav-link disabled" tabindex="-1" aria-disabled="true">Disabled</a>
</li>
</ul>
</div>
</nav>
<nav class="navbar navbar-light bg-light flex-between">
<a href="#" class="navbar-brand">Never Expand</a>
<button class="navbar-toggle" type="button" data-cfw="collapse" data-cfw-collapse-target="#navbarB1">
<span aria-hidden="true">≡</span>
</button>
<div class="navbar-collapse collapse" id="navbarB1">
<ul class="navbar-nav">
<li class="nav-item">
<a href="#" class="nav-link active" aria-current="page">Home</a>
</li>
<li class="nav-item">
<a href="#" class="nav-link">Link</a>
</li>
<li class="nav-item">
<a href="#" class="nav-link disabled" tabindex="-1" aria-disabled="true">Disabled</a>
</li>
</ul>
</div>
</nav>
Responsive Expand
Be default, navbars start out collapsed, but when the target breakpoint is reached, the navbar will expand into a horizontal row of elements.
<nav class="navbar navbar-expand-lg navbar-light bg-light flex-between">
<a href="#" class="navbar-brand">Navbar</a>
<button class="navbar-toggle" type="button" data-cfw="collapse" data-cfw-collapse-target="#navbarR0">
<span aria-hidden="true">≡</span>
</button>
<div class="navbar-collapse collapse" id="navbarR0">
<ul class="navbar-nav">
<li class="nav-item">
<a href="#" class="nav-link active" aria-current="page">Home</a>
</li>
<li class="nav-item">
<a href="#" class="nav-link">Link</a>
</li>
<li class="nav-item">
<a href="#" class="nav-link disabled" tabindex="-1" aria-disabled="true">Disabled</a>
</li>
</ul>
<form class="form-inline ms-auto">
<input class="form-control me-0_25" type="search" placeholder="Search" aria-label="Search">
<button class="btn btn-outline-primary" type="submit">Search</button>
</form>
</div>
</nav>
With the .navbar-brand
in the collapsing area.
<nav class="navbar navbar-expand-lg navbar-light bg-light">
<button class="navbar-toggle" type="button" data-cfw="collapse" data-cfw-collapse-target="#navbarR1">
<span aria-hidden="true">≡</span>
</button>
<div class="navbar-collapse collapse" id="navbarR1">
<a href="#" class="navbar-brand">Navbar</a>
<ul class="navbar-nav">
<li class="nav-item">
<a href="#" class="nav-link active" aria-current="page">Home</a>
</li>
<li class="nav-item">
<a href="#" class="nav-link">Link</a>
</li>
<li class="nav-item">
<a href="#" class="nav-link disabled" tabindex="-1" aria-disabled="true">Disabled</a>
</li>
</ul>
<form class="form-inline ms-auto">
<input class="form-control me-0_25" type="search" placeholder="Search" aria-label="Search">
<button class="btn btn-outline-primary" type="submit">Search</button>
</form>
</div>
</nav>
Supported Content
Navbars come with built-in support for a handful of sub-components. Mix and match from the following as you need:
.navbar-brand
for your company, product, or project name..navbar-nav
for navigation links (including support for dropdowns)..form-inline
for any form controls and actions..navbar-text
for adding vertically aligned text content with support for recoloring, using color scheme..navbar-toggle
for use with our Collapse widget and other navigation toggling behaviors..collapse.navbar-collapse
for grouping and hiding navbar contents by a parent breakpoint.
Here's an example of some sub-components included in a default, light navbar:
<nav class="navbar navbar-expand-lg navbar-light bg-light flex-between">
<a href="#" class="navbar-brand">Navbar</a>
<button class="navbar-toggle" type="button" data-cfw="collapse" data-cfw-collapse-target="#navbar0">
<span aria-hidden="true">≡</span>
</button>
<div class="navbar-collapse collapse" id="navbar0">
<ul class="navbar-nav">
<li class="nav-item">
<a href="#" class="nav-link active" aria-current="page">Home</a>
</li>
<li class="nav-item">
<a href="#" class="nav-link">Link</a>
</li>
<li class="nav-item">
<a href="#" class="nav-link disabled" tabindex="-1" aria-disabled="true">Disabled</a>
</li>
</ul>
<form class="form-inline ms-auto">
<input class="form-control me-0_25" type="search" placeholder="Search" aria-label="Search">
<button class="btn btn-outline-primary" type="submit">Search</button>
</form>
</div>
</nav>
Brand
The .navbar-brand
can be applied to most elements, but an anchor works best as some elements might require utility classes or custom styles.
<nav class="navbar navbar-light bg-light">
<a href="#" class="navbar-brand">Navbar</a>
</nav>
<nav class="navbar navbar-light bg-light">
<h1 class="navbar-brand mb-0">Navbar</h1>
</nav>
Adding images to the .navbar-brand
will likely always require custom styles or utilities to properly size. Here are some examples to demonstrate.
<!-- Just an image -->
<nav class="navbar navbar-light bg-light">
<a class="navbar-brand" href="#">
<img src="/assets/4.0/img/home.svg" width="30" height="30" alt="">
</a>
</nav>
<!-- Image and text -->
<nav class="navbar navbar-light bg-light">
<a class="navbar-brand" href="#">
<img src="/assets/4.0/img/home.svg" width="30" height="30" class="d-inline-block align-top" alt="">
Navbar
</a>
</nav>
Nav
Navbar navigation builds on some of the .nav
options with their own modifier class and require the use of toggler classes for proper responsive styling.
Add .active
directly to a .nav-link
, to indicate a certain state, such as the current page.
<nav class="navbar navbar-expand-lg navbar-light bg-light flex-between">
<div class="navbar-brand">Navbar</div>
<button class="navbar-toggle" type="button" data-cfw="collapse" data-cfw-collapse-target="#navbar1">
<span aria-hidden="true">≡</span>
</button>
<div class="navbar-collapse collapse" id="navbar1">
<ul class="navbar-nav">
<li class="nav-item">
<a href="#" class="nav-link active" aria-current="page">Home</a>
</li>
<li class="nav-item">
<a href="#" class="nav-link">Features</a>
</li>
<li class="nav-item">
<a href="#" class="nav-link">Pricing</a>
</li>
<li class="nav-item">
<a href="#" class="nav-link disabled" tabindex="-1" aria-disabled="true">Disabled</a>
</li>
</ul>
</div>
</nav>
And because we use classes for our navs, you can avoid the list-based approach entirely if you like.
<nav class="navbar navbar-expand-lg navbar-light bg-light flex-between">
<div class="navbar-brand">Navbar</div>
<button class="navbar-toggle" type="button" data-cfw="collapse" data-cfw-collapse-target="#navbar2">
<span aria-hidden="true">≡</span>
</button>
<div class="navbar-collapse collapse" id="navbar2">
<div class="navbar-nav">
<a href="#" class="nav-link active" aria-current="page">Home</a>
<a href="#" class="nav-link">Features</a>
<a href="#" class="nav-link">Pricing</a>
<a href="#" class="nav-link disabled" tabindex="-1" aria-disabled="true">Disabled</a>
</div>
</div>
</nav>
Dropdowns
You may also utilize the Dropdown widget in your navbar nav. 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.
If a dropdown is displayed in a non-expanded navbar, they will display 'inline' with the rest of the navbar menu.
<nav class="navbar navbar-expand-lg navbar-light bg-light flex-between">
<a href="#" class="navbar-brand">Navbar</a>
<button class="navbar-toggle" type="button" data-cfw="collapse" data-cfw-collapse-target="#navbar3">
<span aria-hidden="true">≡</span>
</button>
<div class="navbar-collapse collapse" id="navbar3">
<ul class="navbar-nav">
<li class="nav-item">
<a href="#" class="nav-link active" aria-current="page">Home</a>
</li>
<li class="nav-item">
<a href="#" class="nav-link">Link</a>
</li>
<li class="nav-item">
<a href="#" class="nav-link disabled" tabindex="-1" aria-disabled="true">Disabled</a>
</li>
<li class="nav-item dropdown">
<a class="nav-link" href="#" data-cfw="dropdown">Dropdown<span class="caret" aria-hidden="true"></span></a>
<ul class="dropdown-menu">
<li><a href="#">Action</a></li>
<li><a href="#">Another action</a></li>
<li><a href="#">Something else here</a></li>
</ul>
</li>
</ul>
</div>
</nav>
Forms and Buttons
Place various form controls and components within a navbar with .form-inline
.
<nav class="navbar navbar-light bg-light">
<form class="form-inline">
<input class="form-control me-0_25" type="search" placeholder="Search" aria-label="Search">
<button class="btn btn-outline-primary" type="submit">Search</button>
</form>
</nav>
Align the contents of your inline forms with utilities as needed.
<nav class="navbar navbar-light bg-light flex-between">
<a href="#" class="navbar-brand">Navbar</a>
<form class="form-inline">
<input class="form-control me-0_25" type="search" placeholder="Search" aria-label="Search">
<button class="btn btn-outline-primary" type="submit">Search</button>
</form>
</nav>
Input groups work, too:
<nav class="navbar navbar-light bg-light">
<form class="form-inline">
<div class="input-group">
<span class="input-group-text" id="basic-addon1">@</span>
<input type="text" class="form-control" placeholder="Username" aria-label="Username" aria-describedby="basic-addon1">
</div>
</form>
</nav>
Various buttons are supported as part of these navbar forms, too. This is also a great reminder that vertical alignment utilities can be used to align different sized elements.
<nav class="navbar navbar-light bg-light">
<form class="form-inline">
<button type="button" class="btn btn-outline-success me-0_25">Main button</button>
<button type="button" class="btn btn-small align-middle btn-outline-secondary">Smaller button</button>
</form>
</nav>
Text
Add normal text to your navbars with the help of .navbar-text
. This class adjusts vertical alignment for strings of text.
<nav class="navbar navbar-light bg-light">
<span class="navbar-text">Navbar text example</span>
</nav>
Using the utility classes, you can change the alignment and appearance of your navbar text.
<nav class="navbar navbar-light bg-light flex-end">
<span class="navbar-text text-danger">
Navbar text aligned right
</span>
</nav>
You can also use utility classes to align navbar text to other navbar elements like the brand and navigation.
<nav class="navbar navbar-expand-lg navbar-light bg-light flex-between">
<a href="#" class="navbar-brand">Navbar</a>
<button class="navbar-toggle" type="button" data-cfw="collapse" data-cfw-collapse-target="#navbar6">
<span aria-hidden="true">≡</span>
</button>
<div class="navbar-collapse collapse flex-between" id="navbar6">
<ul class="navbar-nav">
<li class="nav-item">
<a href="#" class="nav-link active" aria-current="page">Home</a>
</li>
<li class="nav-item">
<a href="#" class="nav-link">Link</a>
</li>
<li class="nav-item">
<a href="#" class="nav-link disabled" tabindex="-1" aria-disabled="true">Disabled</a>
</li>
</ul>
<span class="navbar-text">
Navbar text example
</span>
</div>
</nav>
Disabled Links
Add .disabled
to a .nav-link
to indicate a disabled state.
Disabling Anchors

<nav class="navbar navbar-expand-lg navbar-light bg-light flex-between">
<a href="#" class="navbar-brand">Navbar</a>
<button class="navbar-toggle" type="button" data-cfw="collapse" data-cfw-collapse-target="#navbar7">

</nav>
Divider
Place a visual separator between segments of the navbar.
<nav class="navbar navbar-expand-lg navbar-light bg-light flex-between">
<a href="#" class="navbar-brand">Navbar</a>
<button class="navbar-toggle" type="button" data-cfw="collapse" data-cfw-collapse-target="#navbar9">
<span aria-hidden="true">≡</span>
</button>
<div class="navbar-collapse collapse flex-between" id="navbar9">

<a href="#" class="nav-link active" aria-current="page">Home</a>
<a href="#" class="nav-link">Features</a>
<span class="navbar-divider"></span>
<a href="#" class="nav-link">Pricing</a>
<a href="#" class="nav-link">About</a>
</div>
</div>
</nav>
<nav class="navbar navbar-expand-lg navbar-dark bg-dark flex-between">
<a href="#" class="navbar-brand">Navbar</a>
<button class="navbar-toggle" type="button" data-cfw="collapse" data-cfw-collapse-target="#navbar10">
<span aria-hidden="true">≡</span>
</button>
<div class="navbar-collapse collapse flex-between" id="navbar10">
<ul class="navbar-nav">
<li class="nav-item">
<a href="#" class="nav-link active" aria-current="page">Home</a>
</li>
<li class="nav-item">

<li class="nav-item">
<a href="#" class="nav-link">Pricing</a>
</li>
<li class="nav-item">
<a href="#" class="nav-link">About</a>
</li>
</ul>
</div>
</nav>
Collapsible Content
Our Collapse widget can also to toggle hidden content elsewhere on the page.
<nav class="navbar navbar-light bg-light">
<button class="navbar-toggle" type="button" data-cfw="collapse" data-cfw-collapse-target="#exCollapsingNavbar" aria-label="Toggle navigation">
<span aria-hidden="true">≡</span>
</button>
</nav>
<div class="collapse" id="exCollapsingNavbar">
<div class="bg-dark text-light p-1">
<h4>Collapsed content</h4>
Toggleable via the navbar button.
</div>
</div>
Color Schemes
Theming the navbar has never been easier thanks to the combination of a simple link color modifier class and background-color
utilities. Put another way, you specify light or dark and apply a background color.
Here are some examples to show what we mean.
<nav class="navbar navbar-dark bg-dark">
<!-- Navbar content -->
</nav>
<nav class="navbar navbar-dark bg-primary">
<!-- Navbar content -->
</nav>
<nav class="navbar navbar-light" style="background-color: #e3f2fd;">
<!-- Navbar content -->
</nav>
Containers
Although it's not required, you can wrap a navbar in a .container
to center it on a page, or add one within to center the contents of navbar.
<div class="container">
<nav class="navbar navbar-light bg-light">
<a href="#" class="navbar-brand">Navbar</a>
</nav>
</div>
<nav class="navbar navbar-light bg-light">
<div class="container">
<a href="#" class="navbar-brand">Navbar</a>
</div>
</nav>
There may also be instances where you may need to reset the padding on the .navbar
to align with other .container
wrapped content.
The quick brown fox jumped over the lazy dog.
<nav class="navbar navbar-light bg-light px-0">
<div class="container">
<a href="#" class="navbar-brand">Navbar</a>
</div>
</nav>
<div class="container">
<p>The quick brown fox jumped over the lazy dog.</p>
</div>
Placement
Use our position utilities to place navbars in non-static positions. Choose from fixed to the top, fixed to the bottom, or stickied to the top (scrolls with the page until it reaches the top, then stays there). Fixed navbars use position: fixed
, meaning they're pulled from the normal flow of the DOM and may require custom CSS (e.g., padding-top
on the <body>
) to prevent overlap with other elements.
Note: position: sticky
, used for .sticky-top
, isn't fully supported in every browser.
<nav class="navbar navbar-light bg-light">
<a href="#" class="navbar-brand">Static default</a>
</nav>
<nav class="navbar navbar-light bg-light fixed-top">
<a href="#" class="navbar-brand">Fixed top</a>
</nav>
<nav class="navbar navbar-light bg-light fixed-bottom">
<a href="#" class="navbar-brand">Fixed bottom</a>
</nav>
<nav class="navbar navbar-light bg-light sticky-top">
<a href="#" class="navbar-brand">Sticky top</a>
</nav>
