Loading progress on LP?

Question

Landing pages

How to implement loading progress for landing page? For example a window and progress from 0 to 100%. Ajax has not been taught yet, but as I understand it, LP does not need it. I want to learn how to do things like this. Please tell me how this is done in practice.

Answer 1

Percentage loading involves loading a known list of assets and is used in SPA applications.
You have to create all this inside the architecture yourself.
Or just put an endless animation (preloader) until the page is fully loaded (without any percentage).
