 - Navbars and their contents are fluid by default. Use [optional containers](#containers) to limit their horizontal width.
 - Use our [spacing]({{ site.baseurl }}/docs/{{ site.docs_version }}/utilities/spacing/) and [flex]({{ site.baseurl }}/docs/{{ site.docs_version }}/utilities/flex/) utility classes for controlling spacing and alignment within navbars.
 - Navbars are responsive by default, but you can easily modify them to change that. Responsive behavior depends on our Collapse JavaScript plugin.
-- Navbars are hidden by default when printing. Force them to be printed by adding `.d-print` to the `.navbar`. See the [display]({{ site.baseurl }}/docs/{{ site.docs_version }}/utilities/display/) utility class.

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