using khan academy programs in websites

I'm a student using Khan Academy to learn coding, and I've made quite a progress there. I've also learnt a fair bit of HTML, CSS and JS in my college. I was wondering if there's a way to play my game (on Khan Academy, written in ProcessingJS) as an offline HTML page.

Now, I've done a fair amount of research before asking here. I've tried the following:

1. This HTML template on Khan Academy.
2. This template too.
3. And this one on Stack Overflow too.

Using any of the above templates gives me a half-baked output, and it seems that the keyboard controls aren't working. Neither are the animations.

Thanks in advance!

I've created a project which allows KhanAcademy projects to work offline: https://github.com/prolightHub/KaTemplate

Steps:

1. Download it and extract it to where you want it
2. Rename the folder and title in index.html
3. Open js/index.js
4. Put your code into the function:

   function main()
   {
       // Paste your Khan Academy code here
   }
   
   createProcessing(main);
   
   

5. Open index.html

And it should all work.
