What to read to learn how to create modern dynamic sites?

Question

css

Good afternoon!
Please tell me what to read to learn how to create such dynamic sites as:
kit.yandex.ru/mobile/#about
www.yota.ru
Have basic knowledge of JS,HTML. I would like a link to some kind of tutorial on how to make a similar page, for example, so that when scrolling, the necessary info is loaded from the server and the bottom of the page is formed. Of course, I can imagine how this can be implemented, but there are already enough good libraries and therefore I don’t want to write my own bike.
Please also advise useful libraries with a brief description of what they are for.
Thanks in advance!

Answer 1

Do you mean parallax effect?
When does background and content have different scroll speeds? Or when other pages are loaded while scrolling?
parallax effect

Answer 2

Maybe I didn’t notice something, but I didn’t see anything particularly dynamic at all, except for the hash change and at some point the form changes from relative to fixed.
On Yandex, it's not even parallax ... It's just that the scroll reaches some point and starts the animation once. This either builds on jQuery's .scrollTop() or uses the
jQuery Waypoints plugin , which keeps track of which block is in view.

Google sponsored a free course on angular.js there
yota.ru uses jquery and backbone.js libraries ( proof: builtwith.com/yota.ru )
