How to use the bootstrap navbar

How it works

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

• Navbars require a wrapping .navbar with .navbar-expand{-sm|-md|-lg|-xl|-xxl} for responsive collapsing and color scheme classes.
• Navbars and their contents are fluid by default. Change the container to limit their horizontal width in different ways.
• Use our spacing and 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.
• 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.
• Indicate the current item by using aria-current="page" for the current page or aria-current="true" for the current item in a set.
• New in v5.2.0: Navbars can be themed with CSS variables that are scoped to the .navbar base class. .navbar-light has been deprecated and .navbar-dark has been rewritten to override CSS variables instead of adding additional styles.

Note: It’s collected from bootstrap
