Element centered without position:absolute?

Question

css

Straight to the point - pen . The task is to put the green block not equally between the brothers but equally in the middle of the parent without using position:absolute, scripts and fixed sizes/indents of course). Flex is just an example here, you can use everything except the obsolete/condemned one, for example float`a So that green at the same time rests on the brothers if it tries to get into the "occupied" place.
Why do I need this, I don’t know myself, it just became interesting) Probably it will come in handy somewhere
