I'm trying to just run the Angular Material grid layouts demo that can be found here titled Flex Percent Values.

When I add Material Angular elements like md-button they render, although anything layout related doesn't work. I've double checked that I'm importing all the stylesheets I need, and I think I am. I'm not sure what's wrong though.
You're linking to the CSS stylesheet of the 1.0.0-rc4 version but you're loading the scripts of the 0.11.2 version...
I'm pretty sure that this is the problem!

So I am using Bootstrap to create my collapsable elements. I am also using a range selector cdn, and I'm thinking there might be some styles from the BS CSS, specifically to the collapse elements, that are causing the error in UI.
When I place the range selector outside of the collapse element, it looks and works perfectly.

I can't seem to pinpoint where its occuring.
Will work with 2 minor modifications
The range slider initializes itself when the page loads and calculates it's size.
When you enclose the slider in a hidden element, like a Bootstrap collapse, it can't calculate the size correctly. And that's why it looks messed up.
There are a couple of ways we could fix this problem. For example, we could call the slider's reset method to force it to resize correctly. Yet, the simplest solution is to show the collapse on page load, allow the slider to initialize, and then close the collapse. And all this happens without the user noticing anything.
In the markup we add the show invisible class:
<div id="power-range" class="collapse show invisible" data-bs-parent="#container">
And then in a script tag at the end of the page (or a DOMContentLoaded event handler) we remove show invisible class.
<script>
document.querySelector(".show.invisible").classList.remove("show", "invisible");
</script>
The selected answer
The selected answer "fixes" the problem by breaking the Bootstrap collapse control. It doesn't work like OP's original code and has some visible UI problems after the page loads.
Try it
Run the code snippet to understand how it works.
// hide the collapse after range control has initialized
document.addEventListener("DOMContentLoaded", function() {
document.querySelector(".show.invisible").classList.remove("show", "invisible");
});
<div id="container" class="mb-2 p-2 border">
<div>
<button type="button" class="btn btn-primary" data-bs-toggle="collapse" data-bs-target="#power-range">Power</button>
</div>
<div id="power-range" class="collapse show invisible" data-bs-parent="#container">
<range-selector min-range="0" max-range="15" inputs-for-labels />
</div>

I fixed the code by defining a custom class, You are using Bootstrap 5.1.0 where 5.1.3 is the latest so I have used it although it works perfectly on both.

<p id="randomNumber"></p>
</div>
<div class="col-md-3"></div>
</div>
</div>
</body>
</html>
And my JS/jQuery:
$("#generateButton").on("click", function() {
alert("Hello");
})
If you are wondering why the only thing my Random Number Generator is supposed to do is saying "Hello", that's because I was trying to figure out why my code wasn't working properly, and then I found out it was jQuery not working.
The file 'script.js' is linked properly though, because when I tried the normal JS alert with no jQuery code, it worked fine.
This is the part of the code where I am linking to jQuery:
<!-- jQuery library -->
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script src="https://ajax.aspnetcdn.com/ajax/jQuery/jquery-3.3.1.min.js"></script>
<script src="http://code.jquery.com/jquery-1.11.0.js" type="text/javascript"></script>
Yes, I am linking jQuery from 3 different sources, just in case. That is because the first one didn't work, the second one didn't either, so I just wanted to make sure.
Assuming script.js is where your code lives, when you do
<script src="script.js"></script>
There is no $("#generateButton"). You can either move your script to just before the </body>, or wrap you code in
$(function() {
//your code goes here
});
which tells it to wait for the document to load before executing.
You just put your code before loading jquery, you should put your script after not before.
It make sense in programming to import or load the lib before using something from it
$(function(){
$('#generateButton').click(function(){
alert("functional");
})
})

Time ago we purchased this template and we have used it in an angularJS application without any problem.
Now for another project we have switch to Angular 2 and we want use the same theme but we got this weird behaviour: sometimes works as expected but most of the times isn't working.
We have inspected the code using the firefox console and this is the result when is working:
And this is the output console when is not working:
For an (mine) unknown reason sometimes materialize.min.js is not listening for events.
Unfortunately due to copyright issue I can't post the materialize.min.js source code but I can post mine:

EDIT
Even if I use a local copy of jQuery is not working properly.
Provided your materialize.min.js relies on jQuery, I would suspect the reason it works sometimes and not others is that your CDN link is not always loading correctly. I might suggest downloading a copy of jQuery and loading it from a local source that you control.
Edit: When you say "not working" when loaded from a local source, do you mean it is still working sometimes but not consistently? Or do you mean not working at all?
I am trying to learn Bootstrap following this Orielly Bootstrap book.
This is the simple html code:
<!DOCTYPE html>
<html>
<head>
<title>Bootstrap 101 Template</title>
<link href="css/bootstrap.css" rel="stylesheet">
</head>
<body>
<h1>Hello, world!</h1>
<script src="js/bootstrap.min.js"></script>
<div class="row">
<div class="span8">Span 8</div>
<div class="span4">Span 4</div>
</div>
</body>
</html>
I have downloaded Bootstrap and I have bootstrap.css and bootstrap.min.js at correct places. As per the code, we should get a row with 2 columns. But I am getting output as :
Please let me know what is the correct way of doing this?
class="span8"
It looks like the book you are reading is out of date. That is the syntax used in Bootstrap 2 (which is no longer supported).
Presumably you have downloaded the CSS for Bootstrap 3 or 4. Consult their documentation for the current syntax, which has changed significantly since Bootstrap 2.
Also added the viewport meta required for bootstrap
<!DOCTYPE html>

<div class="row">
<div class="col-md-8">Span 8</div>
<div class="col-md-4">Span 4</div>
</div>
</body>
</html>
You are using old syntax of Bootstrap 2. Let's switch to BS3 or 4.
For a basic thing (testing, playing, whatever). I would recommend to use CDN source for Bootstrap. And get through to all documentation.

You need to call a class in div container/container-fluid .

I think it's not in the documentation or I just missed it.
You should have a single html document with a <div data-role="page"> for each page that you need in your application. Check out source code of Multi page template.
