I'm happy to hear that. Even if you did not like the behaviour here, it is good to see that the css worked as planned. It indeed is a responsive design that will adapt the columns, from 3 to 1. After that the blocks get smaller. Sadly flex-wrap seems to be not animatable, that might have helped here.

It would not work to force the layout to remain, there is not one good configuration that looks good on all displays.
