The HTML file comes from the server, but the DOM only exists inside your browser (where the JavaScript program is also running).

For any effects of user interaction to be permanent, the page would need to send data back to the server (typically done with a form) and then code running in the server would need to react to the incoming data and modify files and/or databases.

This is a much more advanced process covered in later courses.
