I copied this from the bootstrap site itself and moment I pasted it on my dreamweaver and loaded it, the bar was there as well as the collapsed button.

The problem is definitely with your bootstrap dependency files. Using CDN for js and css, page will easily work, or else to work offline, you should download the bootstrap files and should place in correct order and import same in correct order Refer.
You can try this (using Bootstrap CDN):

Looks like the order of your javascript files are incorrect.
Also you don't need both bootstrap.js and bootstrap.bundle.js - just use the bundle as it is bootstrap.js + popper.js in 1 combined file (see: https://getbootstrap.com/docs/4.1/getting-started/contents/#js-files).
So... try changing your javascript to:
<!-- SCRIPT -->
<script src="js/jquery-1.11.2.min.js"></script>
<script src="js/bootstrap.bundle.js"></script>
<!-- END OF SCRIPT -->
EDIT: It also looks like your css files are also in the wrong order & you don't need them all.. Change them to:
<link rel="stylesheet" type="text/css" href="css/bootstrap.css"/>
<link rel="stylesheet" type="text/css" href="css/style.css"/>

You need to add Bootstrap JavaScript bundle.
Place the following <script> near the end of your pages, right before the closing </body> tag.
<script src="https://cdn.jsdelivr.net/npm/bootstrap#5.0.2/dist/js/bootstrap.bundle.min.js" integrity="sha384-MrcW6ZMFYlzcLA8Nl+NtUVF0sA7MsXsP1UyJoMp4YLEuNSfAP+JcXn/tWtIaxVXM" crossorigin="anonymous"></script>
JavaScript bootstrap plugin missing in your code. You've to include both the plugins and dependency,bootstrap.bundle.js and bootstrap.bundle.min.js.

Why isn't my bootstrap navbar-toggler button working?

So I have my navbar and I made it so that in a large screen it shows the items in the navabar, but in a small screen a button shows up so you can click it to toggle the items in the navbar. It serves it's purpose in the large screen, however when it comes to the small screen, it shows the button but it does nothing when I click it. Am I missing something? Here's the code:

The nav element is there, but Bootstrap 4 doesn't include navbar-inverse class. That's why you can't see it.
You can use navbar-dark and bg-dark classes instead, which gives you the desired effect that I think you want.

How do I make the elements line up as shown in the following image
Also, what's the best approach for debugging such issues? What tools can I use to work out why a page is displaying in an unexpected manner or why the browser is laid out elements the way it has?
You are missing to include the Bootstrap 3 framework css links and js, you can use the CDN provided on official bootstrap 3.3 docs:

You fiddle updated: https://jsfiddle.net/e7gdk04v/8/
To archieve your layout you can use the Bootstrap 3 grid system, inside your class="container" div create a new div with class="row" and use the grid, for example on the textarea div wrapper add class="col-12" and make the text area 100% width.

It's not data-toogle, it's data-toggle.
Fix the typo:
data-toogle="collapse"
