The navbar is a wrapper that positions branding, navigation, and other elements in a concise header. It's easily extensible and, thanks to our Collapse plugin, can easily integrate responsive behaviors.

Contents

• Will be replaced with the ToC, excluding the "Contents" header {:toc}

How it works

Here's what you need to know before getting started with the navbar:

• Navbars require a wrapping .navbar with .navbar-toggleable-* 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 utility classes.
• Navbars are responsive by default, but you can easily modify them to change that. Responsive behavior depends on our Collapse JavaScript plugin.
• 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.

Read on for an example and list of supported sub-components.

Supported content

Navbars come with built-in support for a handful of sub-components. Choose from the following as needed:

• .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 behaviors.
• .form-inline for any form controls and actions.
• .navbar-text for adding vertically centered strings of text.
• .collapse.navbar-collapse for grouping and hiding navbar contents by a parent breakpoint.

Here's an example of all the sub-components included in a responsive light-themed navbar that automatically collapses at the md (medium) breakpoint.

{% example html %}

Navbar

• Home (current)
• Link

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 %}

Adding images to the .navbar-brand will likely always require custom styles or utilities to properly size. Here are some examples to demonstrate.

Nav

Navbar navigation links build on our .nav options with their own modifier class and require the use of toggler classes for proper responsive styling. Navigation in navbars will also grow to occupy as much horizontal space as possible to keep your navbar contents securely aligned.

Active states—with .active—to indicate the current page can be applied directly to .nav-links or their immediate parent .nav-items.

{% example html %}

Navbar

• Home (current)
• Features
• Pricing
• Disabled

{% endexample %}

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

{% example html %}

Navbar

Home (current) Features Pricing Disabled

{% 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 %}

Navbar

• Home (current)
• Features
• Pricing
• Dropdown link
  Action Another action Something else here

{% endexample %}

Forms

Place various form controls and components within a navbar with .form-inline.

{% example html %}

Search {% endexample %}

Align the contents of your inline forms with utilities as needed.

{% example html %}

Navbar Search {% endexample %}

Input groups work, too:

{% example html %}

@

{% endexample %}

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.

{% example html %}

Main button Smaller button {% endexample %}

Text

Navbars may contain bits of text with the help of .navbar-text. This class adjusts vertical alignment and horizontal spacing for strings of text.

{% example html %}

Navbar text with an inline element {% endexample %}

Mix and match with other components and utilities as needed.

{% example html %}

Navbar w/ text

• Home (current)
• Features
• Pricing

Color schemes

Theming the navbar has never been easier thanks to the combination of theming classes and background-color utilities. Choose from .navbar-light for use with light background colors, or .navbar-inverse for dark background colors. Then, customize with .bg-* utilities.

Navbar

<div class="collapse navbar-collapse" id="navbarColor01">
  <ul class="navbar-nav mr-auto">
    <li class="nav-item active">
      <a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>

  </form>
</div>

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 %}

Navbar

{% endexample %}

When the container is within your navbar, its horizontal padding is removed at breakpoints lower than your specified .navbar-toggleable-* class. This ensures we're not doubling up on padding unnecessarily on lower viewports when your navbar is collapsed.

{% example html %}

Navbar

{% 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 %}

Responsive behaviors

Navbars can utilize .navbar-toggler, .navbar-collapse, and .navbar-toggleable-* classes to change when their content collapses behind a button. In combination with other utilities, you can easily choose when to show or hide particular elements.

Toggler

Navbar togglers can be left or right aligned with .navbar-toggler-left or .navbar-toggler-right modifiers. These are absolutely positioned within the navbar to avoid interference with the collapsed state. You can also use your own styles to position togglers. Below are examples of different toggle styles.

With no .navbar-brand shown in lowest breakpoint:

{% example html %}

Hidden brand

• Home (current)
• Link
• Disabled

Search

{% endexample %}

With a brand name shown on the left and toggler on the right:

{% example html %}

Navbar

• Home (current)
• Link
• Disabled

Search

{% endexample %}

External content

Sometimes you want to use the collapse plugin to trigger hidden content elsewhere on the page. Because our plugin works on the id and data-target matching, that's easily done!

{% example html %}

Collapsed content

Toggleable via the navbar brand.
