• Navigation Links: You can add navigation links to different sections of your website or external pages.
• Mobile Menu: On smaller screens, the navbar can be transformed into a mobile menu with a hamburger icon, ensuring a seamless user experience.

Usage

To use the Bootstrap 4 Navbar, you need to include the Bootstrap CSS and JavaScript files in your project. Then, you can use the following HTML structure to create the navbar:

<nav class="navbar navbar-expand-lg navbar-light bg-light">
  <a class="navbar-brand" href="#">Logo</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</a>
      </li>
      <li class="nav-item">
        <a class="nav-link" href="#">About</a>
      </li>
      <li class="nav-item">
        <a class="nav-link" href="#">Services</a>
      </li>
      <li class="nav-item">
        <a class="nav-link" href="#">Contact</a>
      </li>
    </ul>
  </div>
</nav>

In the above example, the navbar is created with a light background color (bg-light). The brand logo is added using the navbar-brand class, and the navigation links are placed inside a collapsible container. The navbar-toggler button enables the collapsible behavior.

You can further customize the navbar by adding additional classes provided by Bootstrap or by adding your own CSS rules.

Conclusion

The Bootstrap 4 Navbar is a versatile component that helps you create a responsive and user-friendly navigation bar for your website or web application. With its numerous features and customization options, you can easily create a navigation menu that aligns with your project's requirements.
