  • Navbars require a wrapping .navbar with .navbar-expand{-sm|-md|-lg|-xl} for responsive collapsing and color scheme classes.
  • Navbars and their contents are fluid by default. Use optional containers to limit their horizontal width.
  • 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.
  • Navbars are hidden by default when printing. Force them to be printed by adding .d-print to the .navbar. See the display utility class.
  • 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.
