How to change Bootstrap Navbar color
      Theming the navbar has never been easier thanks to the combination of theming classes and
      background-color utilities. Choose from .navbar-light for use with
      light background colors, or .navbar-dark for dark background colors. Then,
      customize with .bg-* utilities.
