Modal not displaying although I followed the video exactly

I've pasted my code for the buttons and modal below. It's not working like the video indicates. My modal isn't displaying when I've clicked the buttons although I've specified them in the data target for the button. What's happening here..?

<button type="button" class="btn btn-primary btn-lg" data-bs-toggle="modal" data-bs-target="#register">Register Now</button>

<button type="button" class="btn btn-outline-info btn-lg d-block mx-auto my-5" data-bs-toggle="modal" data-bs-target="#register">Don't Miss Out, Register Now</button>

<div class="modal fade" id="register" tabindex="-1" aria-labelledby="register form" aria-hidden="true"> <div class="modal-dialog"> <div class="modal-content"> <div class="modal-header"> <h1 class="modal-title fs-5" id="exampleModalLabel">Register for Full Stack Conf</h1> <button type="button" class="btn-close" data-bs-dismiss="modal" aria-label="Close"></button> </div> <div class="modal-body"> Form goes here... </div> <div class="modal-footer"> <button type="button" class="btn btn-secondary" data-bs-dismiss="modal">Close</button> <button type="button" class="btn btn-primary">Save changes</button> </div> </div> </div> </div>

When posting code, always use Markdown formatting to preserve the code's appearance and retain special symbols. An even better way to share code and make your issue easy to replicate is to make a snapshot of your workspace and post the link to it here.

Try removing the quotes over where you have button so instead of ---"button" class= --- remove the second ---"--- so ---"button class =---

I was having the same issue, but was able to resolve it by updating the CSS and JS cdn links used in the workspace to the current Bootstrap version, here: https://getbootstrap.com/docs/5.3/getting-started/download/

The attributes in the version used in the video are missing "bs-".

Video button tag:

<button type="button" class="btn btn-primary btn-lg" data-bs-toggle="modal" data-bs-target="#register">Register Now</button>

Bootstrap version 5.3 button tag:

<button type="button" class="btn btn-primary btn-lg" data-bs-toggle="modal" data-bs-target="#register">Register Now</button>

If you update the cdn links, or just remove "bs-" from the two attributes, it should work.
