How to make a flex grid?

Question

css

Goodnight!
I built a grid on flexbox.
I want to make something similar, but rubber.
I saw how they do something similar using the order function , like this .
Is it possible? If yes then how?

And in the photo this is what I want to get in the end.

Answer 1

I made several adaptive variants of this grid.

Answer 2

This is unlikely to happen, blocks after a large block can only be done probably through margin-top: -50% of the type. It's not even about the order.
