The navbar is fully contained by an HTML5 Nav tag. Inside a recommended container div, there are 2 main parts of the navbar. A logo or brand link, and the navigations links. You can align these links to the left or right.

Fixed Navbar

To make the navbar fixed, you have to add an outer wrapping div with the class navbar-fixed. This will offset your other content while making your nav fixed. You can adjust the height of this outer div to change how much offset is on your content.

DEMO: You can see the theme top nav is fixed.

Mobile Collapse Button

When your nav bar is resized, you will see that the links on the right turn into a hamburger icon . Take a look at the example below to get this functionality. Add the entire button-collapse line to your nav.
