Sticky Bootstrap navigation bar remains pinned at the top of the webpage

I'm encountering an issue with the Bootstrap navigation bar. I've been using the sticky mode as outlined in the documentation:

<nav class="navbar sticky-top navbar-light bg-light">
  <a class="navbar-brand" href="#">Sticky top</a>
</nav>

<router-outlet (deactivate)="onDeactivate()"></router-outlet>
<app-footer></app-footer>

Upon opening the page, the navigation bar is at the top as expected. However, when I scroll down, it remains fixed at the top of the page instead of following along with the scrollbar. I'm unsure if my understanding of how it should work is incorrect or if there is a problem with the code above. Could it be possible that it's not functioning properly due to the existing codebase on my page (which is almost complete and I only wanted to add this feature at the end)?

Answer №1

When using the sticky-top class, a fixed position is applied to the navbar at top:0 left:0 once you scroll down past its height. This effectively locks the navbar to the top of the viewport while allowing the underlying page to scroll normally. The navbar will remain fixed at the top even after you scroll past it, and it will not move along with the scrollbar anymore.

Answer №2

After some investigation, I discovered the issue was due to me using an outdated version of Bootstrap.

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-alpha.4/css/bootstrap.min.css">

Now, I have updated to:

<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.0/css/bootstrap.min.css">
