fixed navbar is positioned relatively to the screen's viewport and doesn't move when scrolled. To make bottom navbar fixed, move it outside .content-inner container. It's not a part of scrollable area, which means scrollbar will not overlap it.
Navbar component
Navbar is a navigation component, usually displayed on top of the page and includes brand logo, navigation, notifications, user menu, language switcher and other components. By default, navbar has top fixed position and is a direct child of <body> container. Navbar toggler appears next to the brand logo on small screens and can be easily adjusted with display utility classes. You can also control responsive collapsing breakpoint directly in the markup. Navbar component is responsive by default and requires .navbar and .navbar-expand{-sm|-md|-lg|-xl|-xxl} classes. Main navigation bar also has static position, but due to the nature of the general layout, it's moved outside all scrolable containers so that it always appears to be sticked to the top.
Static navbars
By default, top and bottom navbars in content area have static position and scroll away along with content. This use case doesn't require any additional classes for .navbar and <body> containers, this means navbar appearance depends on its placement: in the template top static navbar is the first direct child of .content-inner or .content containers.
Fixed navbars
Fixed navbars depend on location in containers. All navbars placed inside .content-inner container scroll away with the content. Once they are moved outside .content-inner container and placed before or after it, navbar becomes "fixed". It will push the content section up or down and will be always displayed within the viewport despite the scrolling position. None of these options requires any additional class names either in containers or navbar itself. Table below lists all available body and navbar classes.
Navbar markup
Navbar markup consists of a set of containers with mandatory and optional classes: .navbar is a wrapper, this class is required for all types of navbars; .navbar-[color] - sets main background color theme and adjusts content color; .navbar-expand-[breakpoint] - responsible for collapsing navbar content behind the button on small screens. See the table below for a full list of classes.
