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 plugin, it can easily integrate offscreen content.

- Will be replaced with the ToC, excluding the "Contents" header {:toc}
Basics
Here's what you need to know before getting started with the navbar:
- Navbars require a wrapping
.navbar
and a color scheme class (either.navbar-default
or.navbar-inverse
). - When using multiple components in a navbar, some alignment classes are required.
- Navbars and their contents are fluid by default. Use optional containers to limit their horizontal width.
- Use
.pull-left
and.pull-right
to quickly align sub-components. - 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.
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 a full-height and lightweight navigation (including support for dropdowns).navbar-form
for vertically centering default-sized inputs and buttons..navbar-toggler
for use with our collapse plugin and other navigation toggling behaviors.
Here's an example of all the sub-components included in a default, light navbar:
{% example html %}

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.
{% highlight html %}
{% endhighlight %}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 only center the contents of the navbar.
{% example html %}
{% endexample %}{% example html %}
{% endexample %}Collapsible content
Our collapse plugin allows you to use a <button>
or <a>
to toggle hidden content.
{% example html %}
☰ {% endexample %}For more complex navbar patterns, like those used in Bootstrap v3, use the .navbar-toggleable-*
classes in conjunction with the .navbar-toggler
. These classes override our responsive utilities to show navigation only when content is meant to be shown.
