Obtaining just the Navigation Bar component from Bootstrap

I am currently working with Bootstrap's framework specifically for the navigation bar. My client's website has a complex menu with multiple dropdowns, so utilizing Bootstrap seemed like the most efficient approach. However, when I attempted to download only the necessary CSS/JS/jquery components following tutorials from Stack Overflow, I noticed that some of the CSS styles were not being applied. Even though the JS functionality was functioning correctly, the navigation links (with classes like nav-link and nav-item) lacked the proper styles, resulting in a broken layout. It appears that there is something crucial that I may have overlooked. My suspicion is that it could be related to compatibility issues between alpha and beta versions of Bootstrap, but I cannot be certain. Any guidance on this matter would be greatly appreciated as I am hesitant to overwrite all of Bootstrap's default styles just for the navigation bar.

edit: I have included screenshots to demonstrate my efforts in troubleshooting the issue before seeking assistance here. Despite having more than a year of coding experience, this problem has stumped me, prompting me to post a question. Apologies for the delayed addition of screenshots.

Answer №1

After some trial and error, I was able to solve this issue. It turns out that Bootstrap does not have customized compiled files available for Bootstrap 4 like they do for version 3.4. There appears to be a difference in styling between versions 3.4 and 4, particularly with classes such as .nav-link and .nav-item which were causing conflicts. To work around this, I carefully listed all the class & ID names used in my existing Bootstrap 4 navigation bar, reviewed Bootstrap 4's main CSS file, extracted the necessary classes, and created a separate CSS file specifically for the navigation elements. I then removed the CDN link, added a reference to my new CSS file containing only the required navigation classes, and ensured that the latest Bootstrap JS CDN was included (using their provided link).

I plan on sharing a codepen link later today to showcase my solution, as I believe others may encounter similar challenges when trying to customize Bootstrap's CSS solely for the navigation bar.

Answer №2

For a simple navigation bar, you can use the following code:

html:
    <nav class="navbar navbar-expand-lg navbar-dark bg-dark fixed-top">
        <div class="container">
          <a class="navbar-brand" href="#">Start Bootstrap</a>
          <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarResponsive" aria-controls="navbarResponsive" aria-expanded="false" aria-label="Toggle navigation">
            <span class="navbar-toggler-icon"></span>
          </button>
          <div class="collapse navbar-collapse" id="navbarResponsive">
            <ul class="navbar-nav ml-auto">
              <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="#">Link 1</a>
              </li>
              <li class="nav-item">
                <a class="nav-link" href="#">Link 2</a>
              </li>
              <li class="nav-item">
                <a class="nav-link" href="#">Link 3</a>
              </li>
            </ul>
          </div>
        </div>
      </nav>
js:
<script src="vendor/jquery/jquery.min.js"></script>
  <script src="vendor/bootstrap/js/bootstrap.bundle.min.js"></script>
