I can’t figure out what is wrong, but I bet they all have the same problem. So if we find it in one, we should find it in all of them.
They link maxcdn,bootstrapcdn,com/bootstrap/4.3.1/(css&js)/bootstrap.min.(css&js)

Problem is with bootstrap JS library. Even you don't use this library, your code also work.

Answer 2

No it's not. You are getting error because you missed to include jQuery library.

Add jQuery library in your code above the bootstrap js library. It will work

https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"

Answer 3

The last part means that they all link to
https://maxcdn.bootstrapcdn.com/bootstrap/4.3.1/js/bootstrap.min.js
and
https://maxcdn.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css
