I'm following this text to make a section of my webpage show all columns with same height: https://medium.com/wdstack/bootstrap-equal-height-columns-d07bc934eb27
But trying to fit into my CSS logic I can't get it right, my scratch: https://www.codeply.com/go/Bspc3JC2r2
I tried to insert row display-flex or just display-flex into different places, but didn't work.
I saw some solutions around here(some of them pretty old), but a lot of them are not recommended cause they can break responsiveness. I hope is there a way to fix this, or a better way to do that.
