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 `.navbar` and a [color scheme](#color-schemes).
- Navbars and their contents are fluid by default. Use [optional containers](#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 a `role="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 %}
<nav class="navbar navbar-light bg-faded">
<a class="navbar-brand" href="#">Navbar</a>
<ul class="nav navbar-nav">
<li class="nav-item active">
<a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Features</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Pricing</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">About</a>
</li>
</ul>
<form class="form-inline navbar-form pull-right">
<input class="form-control" type="text" placeholder="Search">
<button class="btn btn-success-outline" type="submit">Search</button>
</form>
</nav>
{% 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.
<div class="bd-example">
<nav class="navbar navbar-dark bg-inverse">
<a class="navbar-brand" href="#">Navbar</a>
<ul class="nav navbar-nav">
<li class="nav-item active">
<a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Features</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Pricing</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">About</a>
</li>
</ul>
<form class="form-inline navbar-form pull-right">
<input class="form-control" type="text" placeholder="Search">
<button class="btn btn-info-outline" type="submit">Search</button>
</form>
</nav>
<nav class="navbar navbar-dark bg-primary">
<a class="navbar-brand" href="#">Navbar</a>
<ul class="nav navbar-nav">
<li class="nav-item active">
<a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Features</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Pricing</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">About</a>
</li>
</ul>
<form class="form-inline navbar-form pull-right">
<input class="form-control" type="text" placeholder="Search">
<button class="btn btn-secondary-outline" type="submit">Search</button>
</form>
</nav>
<nav class="navbar navbar-light" style="background-color: #e3f2fd;">
<a class="navbar-brand" href="#">Navbar</a>
<ul class="nav navbar-nav">
<li class="nav-item active">
<a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Features</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Pricing</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">About</a>
</li>
</ul>
<form class="form-inline navbar-form pull-right">
<input class="form-control" type="text" placeholder="Search">
<button class="btn btn-primary-outline" type="submit">Search</button>
</form>
</nav>
</div>
{% highlight html %}
<nav class="navbar navbar-dark bg-inverse">
<!-- 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>
{% 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 %}
<div class="container">
<nav class="navbar navbar-light bg-faded">
<a class="navbar-brand" href="#">Navbar</a>
</nav>
</div>
{% endexample %}
{% example html %}
<nav class="navbar navbar-light bg-faded">
<div class="container">
<a class="navbar-brand" href="#">Navbar</a>
</div>
</nav>
{% 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 %}
<nav class="navbar navbar-full navbar-light bg-faded">
<a class="navbar-brand" href="#">Full width</a>
</nav>
{% endexample %}
{% example html %}
<nav class="navbar navbar-fixed-top navbar-light bg-faded">
<a class="navbar-brand" href="#">Fixed top</a>
</nav>
{% endexample %}
{% example html %}
<nav class="navbar navbar-fixed-bottom navbar-light bg-faded">
<a class="navbar-brand" href="#">Fixed bottom</a>
</nav>
{% endexample %}
## Collapsible content
Our collapse plugin allows you to use a `<button>` or `<a>` to toggle hidden content.
{% example html %}
<div class="collapse" id="exCollapsingNavbar">
<div class="bg-inverse p-a">
<h4>Collapsed content</h4>
<span class="text-muted">Toggleable via the navbar brand.</span>
</div>
</div>
<nav class="navbar navbar-light bg-faded">
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#exCollapsingNavbar">
&#9776;
</button>
</nav>
{% 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 %}
<nav class="navbar navbar-light bg-faded">
<button class="navbar-toggler hidden-sm-up" type="button" data-toggle="collapse" data-target="#exCollapsingNavbar2">
&#9776;
</button>
<div class="collapse navbar-toggleable-xs" id="exCollapsingNavbar2">
<a class="navbar-brand" href="#">Responsive navbar</a>
<ul class="nav navbar-nav">
<li class="nav-item active">
<a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Features</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Pricing</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">About</a>
</li>
</ul>
</div>
</nav>
{% endexample %}
