When loading HTML using JavaScript, the CSS within the HTML is not properly processing. Leveraging Bootstrap 5 might help resolve

Currently utilizing bootstrap 5 for my project. I have a setup in index.html where I am loading the contents of nav.html using JavaScript. However, I am facing an issue wherein the CSS styling for the navbar is not being applied when loaded via JS. Strangely, it works perfectly fine if I directly copy the code from nav.html into index.html.

For example, the defined colors in main.css for navbar and navbar-brand do not appear when nav.html is dynamically loaded into index.html. But if the nav code resides directly in index.html without JS loading, the colors are displayed correctly.

The goal is to reuse the nav.html across multiple pages, but the styling seems to be missing. Any insights on this matter?

index.html

            <div id="nav-placeholder"></div>
            <script>
              $(function(){ $("#nav-placeholder").load("nav.html") });

  <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">
    <span class="navbar-toggler-icon"></span>
  </button>

  <div class="collapse navbar-collapse" id="navbarSupportedContent">

      </li>
    </ul>

</nav>

main.css

.navbar {
  background-color: #ff00ff;
}
.navbar-brand {
  color: #ff0000;
}

Answer №1

When checking the Network tab in the developer console, what status code are you seeing? It's possible that there is an issue with the path to your html file.

If you don't want to use a self-invoking expression, you can try this:

$("#nav-placeholder").load("nav.html");

Alternatively, if you prefer a self-invoking expression, you can use this code:

(function(){ $("#nav-placeholder").load("nav.html"); })();

Answer №2

Oh no, I made a silly mistake. It turns out the issue lies in the order of my CSS.

For example:

Changing from

class="navbar navbar-expand-lg navbar-light bg-light"

to

class="navbar navbar-expand-lg"

fixed the problem and now the navigation bar displays correctly with the colors from main.css
