The Navbar symbol below can be placed on any page. If you update it in one instance (like below), it will update across the entire website.

It's common to have multiple different navbars. It's also common to move sub-elements outside of the container and removing the container from navbars. If you do this, make sure to add padding on the left and right hand side of the navbar.

Navbars are typically not inside of a container, they usually site inside of a section or above sections. Add the fixed class to it to make the navbar in the fixed position (this will place it at the top of the page and the navbar will stay on the page while you're scrolling).
