Library doesn't work if the protocol is not specified.

Wrong:

<script src="code.jquery.com/jquery-1.12.4.js"></script> <script src="code.jquery.com/ui/1.12.1/jquery-ui.js"></script>

Right:

<script src="**http://**code.jquery.com/jquery-1.12.4.js"></script> <script src=**http://**code.jquery.com/ui/1.12.1/jquery-ui.js"></script>

Tried with Firefox (61) and Microsoft Edge (42).

I guess it is because your browser tries to find the file in your computer. I guess it is trying to look for a folder called code.jquery.com within your current working directory and it does not exist.

This works correctly. Please look for programming help on Stack Overflow.
