[//]: # DO NOT EDIT IT WILL BE OVERWRITTEN - copy of bootstrap documentation generated by grunt docs-copy-bootstrap-docs
{% callout info %} Bootstrap Reference Documentation This is a part of the reference documentation from Bootstrap. It is included here to demonstrate rendering with Material Design for Bootstrap default styling. See the Material Design section for more elements and customization options. {% endcallout %}
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.
Contents
- 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
.navbarand a color scheme. - Navbars and their contents are fluid by default. Use optional containers to limit their horizontal width.
- Use
.pull-*-leftand.pull-*-rightto 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-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.
Here's an example of all the sub-components included in a default, light navbar:
{% example html %}
Navbar Search {% endexample %}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.
{% example html %}

Nav
Navbar navigation is similar to our regular nav options—use the .nav base class with a modifier to achieve a particular look. In this case you'll want .nav.navbar-nav.
{% example html %}
{% endexample %}And because we use classes for our navs, you can avoid the list-based approach entirely if you like.
{% example html %}
{% endexample %}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.
{% 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 a fixed or static top navbar.
{% example html %}
{% endexample %}{% example html %}
{% endexample %}Placement
Navbars can be statically placed (their default behavior), static without rounded corners, or fixed to the top or bottom of the viewport.
{% example html %}
Full width {% endexample %}{% example html %}
Fixed top {% endexample %}{% example html %}
Fixed bottom {% 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.
{% example html %}
☰ {% endexample %}
