How to download a website completely on a computer?

Question

Google Chrome

There is such a site www.narbutas.ru
There are cool animations.
I want to understand how they work.
To do this, you need to download the site and deal with the code.
I tried to download via wget, but only these files are downloaded.

Obviously, these are not all files.
I'm assuming there's some kind of blocking going on.
Suggest which way to dig?
Thanks in advance.

Answer 1

yes, anyway, all the code there is minified and compiled, nothing will be parsed
for animation on elements with a timer, these .maintransition- and .fade- classes are put, which are replaced by enter -> active by the timer (and / or when the element appears on the screen) -> leave
(I guess, but most likely something like this)

Answer 2

Webparse.ru if once you can download the whole site for free, if you need several you will have to pay
