html - secundarios - funcion de los bioelementos

Alineación de los elementos secundarios de diferentes contenedores principales

Question

Estoy tratando de alinear verticalmente los elementos de altura variable en los contenedores, es decir, el primer elemento de cada contenedor se alinea verticalmente entre sí, el segundo elemento de cada contenedor se alinea verticalmente entre sí, etc., etc.

Estoy usando flexbox pero no estoy seguro si esto es posible? ¿O es posible usar CSS Grid?
