Achieving consistent card placement in responsive layout with flexbox [closed]

I am currently working on a React project that involves displaying a set of cards inside a container. Each card has a fixed size of 231x237px. I have used flexbox for the layout of the cards. I want the number of columns to be even when moving a card to a new line. For example 2,4. Or 1 (on the smallest devices)

1 row: Card  - Card - Card - Card

or

1 row: Card - Card2 row: Card - Card
