Are there left/right/top/bottom alternatives for block alignment?

Question

css

What are alternative practices for block alignment? As an example, classic dropdown ( link ), is it possible to implement (position) dropdown without using left/right/top/bottom.

The question may arise, at @ # me? Purely for educational, I would even say for scientific purposes. This is such bullshit...

Answer 1

Yes, in fact, all methods work as on other blocks. Though flexes, though magic. Checked it works.
