Question

What steps should I take to resolve my header issues post upgrading to Bootstrap 4?

After updating my Bootstrap files, I noticed that my Navbar is broken. I have been diligently checking and revising my code to align with the documentation on their official website, but I just can't seem to pinpoint what's missing. Initially, I suspected that this code snippet required an update:

  <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#top-navbar-1">
    <span class="sr-only">Toggle navigation</span>
    <span class="icon-bar"></span>
    <span class="icon-bar"></span>
    <span class="icon-bar"></span>
  </button>

So, I made a modification from the above code block to:

  <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>

To provide more context, here is a link to a CodePen showcasing the issue: https://codepen.io/grabthereef/pen/pxGweE. Prior to the version update, the Navbar appeared like this:

Answer 1

Answer №1

To ensure the navbar sits on top of the image placeholders, simply include the fixed-top CSS class in the navbar code:

<nav class="navbar navbar-expand-lg navbar-light bg-light fixed-top">

For more information, check out the documentation: http://getbootstrap.com/docs/4.1/components/navbar/#placement

If you're curious about what may have caused the issue, please share the HTML code prior to switching to bootstrap 4 so we can pinpoint the differences.

It's possible that I am mistaken, but have you considered simply swapping them in this way:
