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-toggler` for use with our collapse plugin and other [navigation toggling](#collapsing-content) 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 pull-xs-right">
    <input class="form-control" type="text" placeholder="Search">
    <button class="btn btn-outline-success" type="submit">Search</button>
  </form>
</nav>
{% 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 %}
<!-- As a link -->
<nav class="navbar navbar-light bg-faded">
  <a class="navbar-brand" href="#">Navbar</a>
</nav>

<!-- As a heading -->
<nav class="navbar navbar-light bg-faded">
  <h1 class="navbar-brand m-b-0">Navbar</h1>
</nav>

{% endexample %}

### 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`.

Active states—with `.active`—to indicate the current page can be applied directly to `.nav-link`s or their immediate parent `.nav-item`s.

{% example html %}
<nav class="navbar navbar-light bg-faded">
  <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>
</nav>
{% endexample %}

And because we use classes for our navs, you can avoid the list-based approach entirely if you like.

{% example html %}
<nav class="navbar navbar-light bg-faded">
  <div class="nav navbar-nav">
    <a class="nav-item nav-link active" href="#">Home <span class="sr-only">(current)</span></a>
    <a class="nav-item nav-link" href="#">Features</a>
    <a class="nav-item nav-link" href="#">Pricing</a>
    <a class="nav-item nav-link" href="#">About</a>
  </div>
</nav>
{% endexample %}

You may also utilize dropdowns 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.

{% example html %}
<nav class="navbar navbar-light bg-faded">
  <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 dropdown">
      <a class="nav-link dropdown-toggle" href="http://example.com" id="navbarDropdownMenuLink" data-target="#" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
        Dropdown link
      </a>
      <div class="dropdown-menu" aria-labelledby="navbarDropdownMenuLink">
        <a class="dropdown-item" href="#">Action</a>
        <a class="dropdown-item" href="#">Another action</a>
        <a class="dropdown-item" href="#">Something else here</a>
      </div>
    </li>
  </ul>
</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 pull-xs-right">
      <input class="form-control" type="text" placeholder="Search">
      <button class="btn btn-outline-info" 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 pull-xs-right">
      <input class="form-control" type="text" placeholder="Search">
      <button class="btn btn-outline-secondary" 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 pull-xs-right">
      <input class="form-control" type="text" placeholder="Search">
      <button class="btn btn-outline-primary" 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 a [fixed or static top navbar](#placement).

{% 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 %}
<nav class="navbar navbar-light bg-faded">
  <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#exCollapsingNavbar" aria-controls="exCollapsingNavbar" aria-expanded="false" aria-label="Toggle navigation">
    &#9776;
  </button>
  <div class="collapse" id="exCollapsingNavbar">
    <div class="bg-inverse text-muted p-a-1">
      <h4>Collapsed content</h4>
      <span class="text-muted">Toggleable via the navbar brand.</span>
    </div>
  </div>
</nav>
{% endexample %}

{% example html %}
<nav class="navbar navbar-dark bg-inverse">
  <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#exCollapsingNavbarDark" aria-controls="exCollapsingNavbarDark" aria-expanded="false" aria-label="Toggle navigation">
    &#9776;
  </button>
  <div class="collapse" id="exCollapsingNavbarDark">
    <div class="bg-inverse text-muted p-a-1">
      <h4>Collapsed content</h4>
      <span class="text-muted">Toggleable via the navbar brand.</span>
    </div>
  </div>
</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" aria-controls="exCollapsingNavbar2" aria-expanded="false" aria-label="Toggle navigation">
    &#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 %}
