How do phonegap apps work?

Question

JavaScript

I do not quite understand what the principle of operation of phonegap applications is.
As far as I understand, the entire GUI of the mobile phonegap application is the usual html (with css and js) that we receive from the server? In other words, such an application does not have a graphical user interface exactly until the server for the application generates html?
Let's say I have a service. It has both a mobile application and a web version (for a browser) of the application. Does it make sense to develop a web version and then just wrap it in phonegap without unnecessary troubles?

Answer 1

These are static files (html, css, js) that are displayed through a web-view (built-in browser), have access to some native functionality of the platform (devices, sensors, file system) through plugins. If there is a connection, they can communicate with remote servers, but this is not necessary.
