Onload modal popup is not working! It works completely when I run it individually but when I attach it to my website code it doesn't work! Why?

How can I solve this issue?
<div class="modal fade" id="onload-modal">
<!-- data-backdrop="static" data-keyboard="false" -->
<div class="modal-dialog modal-dialog-centered modal-sm">
<div class="modal-content">
<div class="modal-header">
<h4 class="modal-title"></h4>
</div>
<div class="modal-body">
<p><img src="#" id="modal-banner" alt="Image"></p>
</div>
<div class="modal-footer">
<button class="btn btn-danger" data-dismiss="modal">Skip</button>
<button class="btn btn-danger" onclick="#">Register Now</button>
</div>
</div>
</div>
</div>
It seems like some other code is clashing with this code. Can you please help?
<script>
$(document).ready(function() {
$("#onload-modal").modal('show');
});
</script>

Instead of showing the modal when the document is ready, try to show the modal when the window is loaded, as below:
<!doctype html>

Bootstrap Modal not popping up when clicking button

I'm trying to add a modal when the user clicks on the 'Add' button under 'Categories.' When I use just the code for the modal in js fiddle, it works, but when I add all of the code from the current file, it doesn't. Have tried moving jquery cdn around and also making a separate div container for the modal, but not able to get it. Any help is appreciated.

The code that you useis only available for Bootstrap 4, but in the header, you are including the Bootstrap 5 that have changed some parameters regarding modals :

You are probably getting your bootstrap versions mixed up. I have tested your code using bootstrap 4 and bootstrap 5 and can confirm it works on bootstrap 4 but does not on bootstrap 5, you can fix your code easily by replacing your bootstrap 5 script imports with bootstrap 4, or you can port your code to bootstrap 5.
Bootstrap 5 recently changed the way modals are triggered, which is why it does not work on 5 but does work on 4.
The following head works for me

The Navbar works just fine. Maybe there is a doc missing from Bootstrap? Thanks for your input.

bootstrap 3 have two buttons aligned in the same row

i have the following html code, and i use bootstrap 3. What i try to achieve is to have the 4 buttons with the klasse text, be the first two in the same row, and the next two, in the next row. Now each button is shown in its own row.
How the below code should be altered?
<div class="background-image background-image--attachment-scroll" style="background-image: url(http://sitefront.png);"> </div>
<div class="background-image-overlay region--dark-typography region--white-background" style="opacity: 0.0;background-size:contain;"> </div>
<div class="container-fluid region--dark-typography region--white-background">
<div class="clearfix block block-block-content block-block-content58f3bb9a-975d-4cef-bb21-a0e3d14ec934" id="block-howprofessionalisourstaff">
<div class="content">
<div class="clearfix text-formatted field field--name-body field--type-text-with-summary field--label-hidden field__item">
<div class="row bottom-spacing-medium">
<div class="col-md-8 col-md-offset-2 text-center">
<div class="row bottom-spacing-medium">
<div class="col-md-8 col-md-offset-2 text-center">
<div class="bottom-spacing-large">
<p class="text-center"><a class="button" href="http://site/">klasse 1</a><a class="button" href="http://site">klasse 2</a><a class="button" href="http://site/">klasse 3</a><a class="button" href="http://site/">klasse 4</a></p>
</div>
<div class="scroll-button smooth-scroll"><span class="sr-only">Content start</span></div>
</div>
</div>
</div>
</div>
</div>
</div>
</div>
</div>
The problem with all suggested solutions, is that when i use the following drupal theme button class, it does not force buttons to be on the same row, when i have for instance text as large as the following in all buttons:
Use Bootstrap’s custom button styles for actions in forms...

you need something like this
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet" />
<div class="container">
<div class="row">
<a class="btn btn-primary" href="http://site/">klasse 1</a>
<a class="btn btn-primary" href="http://site">klasse 2</a>
</div>
<br>
<div class="row">
<a class="btn btn-primary" href="http://site/">klasse 3</a>
<a class="btn btn-primary" href="http://site/">klasse 4</a>
</div>
</div>

Not sure if it is what you would like to achieve, please let me know, if not I'll give you more solutions:
Basically I have deleted button klasse3 & klasse4 from the "p class text-center" and I have added them into another "p class text-center" below.
This is a simple solution, but I think you could achieve a better result with a different solution
Actual Button

Just wrap the button in a div with text-center You are also missing bootstrap classes for the button.
<div class="text-center">
<button
aria-label="Close"
class="btn btn-primary close"
data-dismiss="modal"
type="button"
>
close
</button>
</div>
