i have a html script with button and onclick function script that should take me to google.com, but it doesn't seem to work. Been stuck with this for hours. Im also new to HTML.
Tried everything. Line 336 and 353 should be the needed content. And line 136 should be the button itself. I don't understand whats wrong. Anyone ever have had this issue?

If you're trying to make a button that takes you to google.com, I would advise you to use an a tag, not a button tag. The tag automatically links you to your desired destination when clicked.
Example:
Example
If you want the link to look like a button, then simply look at the css options. I would advise you to look here: https://www.w3schools.com/css/css_link.asp
a {
background-image:linear-gradient(to bottom, lightblue, aquamarine);
padding:5px;
text-decoration:none;
color:black;
padding-right:50px;
padding-left:50px;
margin-top: 50px;
margin-left: 50px;
display: inline-block;
font-size:25px;
border-radius:5px;
box-shadow: 1px 1px green;
}
Example
If you are determined to use a <button> tag, then all you need to do is within that button tag add an onclick attribute. So, you would change your code to <button id="btncmd" onclick="cmd()">Videos</button>.
Example of what you want:
function cmd() {
window.location.href = "https://www.example.com/"; // I'm using example but you can use google.
}
<button id="btncmd" onclick="cmd()">Videos</button>
You did not define btncmd. Adding this line to your code solves the problem:
var btncmd = document.getElementById("btncmd");

Can someone point to the error (why is there no animation?) and how can I fix it?
This codepen has a number of external resources listed. Try clicking on the 'cog' icon to the top left of each of the three windows, and you will see the external resources:

I have the following canvas:
Codepen link
What I want: Equal margin on both sides of canvas without any horizontal scroll bars.
Problem: margin-right property does not to work. I have seen some solutions that solve this problem by specifying a fixed width, but I cannot have a fixed width in my case. I want my canvas to adjust its width height according to the size of the window.
The following Javascript takes care of that:
window.addEventListener('resize' , resizeCanvas , false);
function resizeCanvas(){
canvas.width = window.innerWidth;
canvas.height = window.innerHeight/1.2;
}
So is there a different solution?
For the overflow problem, if I put overflow-x: hidden inside the body then only the scrollbar disappears but the problem persists. The canvas still extends past the screen hence the right border of the canvas is No longer visible.
See here
Here is my code:
HTML
<body onload="start()">
<canvas id="myCanvas"></canvas>
</body>
CSS
body{
}
canvas{
border: 1px solid black;
border-radius: 5px;
background-color: #fff;
margin: auto 50px auto 50px; /* works for left margin but not for right */
}
Thanks!
Another thing:
I have not set width: 100% for the canvas because it distorts the content inside it.
As Chris is saying you need to set the width of the canvas lower than the full width of the page:
canvas.width = window.innerWidth - 100;
Note that you need to take the border-width of the canvas and in your codepen the body also has a margin of 8px into account as well:
canvas.width = window.innerWidth - 118;
CSS calc() method is what you need. Just subtract the margins from 100% and you get the desired result. See the demo below. CSS calc() reference

Hope it helps :)
instead of messing around with margins, just change the width of your canvas and center it.
CSS
canvas {
border: 1px solid black;
border-radius: 5px;
background-color: #fff;
width: 90%!important;

I am trying to include this Codepen into a basic website for school.
The issue is that the code with a few tweaks, will not load locally. I have even put my entire website into Codepen as a test and it worked.
It should just be the cloth simulation and nothing else.
Here is the HTML and CSS in its smallest form.

Thank you for your help.
Assuming you have copy and pasted the website exactly how it is, you're missing opening and closing style tags around the CSS, and script tags around the JS.
Your code works, but you need this tags:
<script type="text/javascript"> YOUR JAVASCRIPT HERE </script>
<style type="text/css"> YOUR CSS HERE </style>
