    <span class="navbar-toggler-icon"></span>
  </button>
  <div class="collapse navbar-collapse" id="navbarNav">
    <ul class="navbar-nav">
      <li class="nav-item active">
        <a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
      </li>
      <li class="nav-item">
        <a class="nav-link" href="#">About</a>
      </li>
      <li class="nav-item">
        <a class="nav-link" href="#">Contact</a>
      </li>
    </ul>
  </div>
</nav>

Example

<nav class="navbar navbar-expand-lg navbar-dark bg-dark">
  <a class="navbar-brand" href="#">My Website</a>
  <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarNav" aria-controls="navbarNav" aria-expanded="false" aria-label="Toggle navigation">
    <span class="navbar-toggler-icon"></span>
  </button>
  <div class="collapse navbar-collapse" id="navbarNav">
    <ul class="navbar-nav">
      <li class="nav-item active">
        <a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
      </li>
      <li class="nav-item">
        <a class="nav-link" href="#">About</a>
      </li>
      <li class="nav-item">
        <a class="nav-link" href="#">Contact</a>
      </li>
    </ul>
  </div>
</nav>

Output

The above example will produce a responsive navigation bar with a logo and three links. The navigation bar will collapse into a hamburger menu for smaller screens.

Explanation

The Bootstrap navbar component is a container that provides a responsive navigation header. The navbar class creates the container, while other classes such as navbar-expand-lg and navbar-light bg-light control its behavior and appearance.

The navbar-brand class is used to create a link to the website's logo or brand. The navbar-toggler class is used to toggle the menu when the screen size is small. The navbar-nav and nav-item classes are used to create navigation links. The sr-only class is used to provide screen reader accessibility.

Use

The Bootstrap navbar component can be used in Angular applications to create a responsive navigation header. It's useful for providing users with easy access to different sections of the website. The navbar can be customized using Bootstrap classes, or by adding custom styles and components.

Important Points

• Use the navbar class to create the container for the navigation bar.
• Use the navbar-expand-lg class to control the responsive behavior of the navbar.
