How to auto-indent a block?

Question

css

Greetings!

There is a copyright and you need to make sure that it automatically moves to the very bottom.
margin-top: auto doesn't work for some reason. On different pages there is a different height of the top block, so you need the copyright to automatically fly to the very bottom on its own.

Thank you in advance!

roughly - body in flex, height 100%, content block flex-grow: 1;
More precisely, already with the layout ...
