Equal Height Cards

Hi all,

I’ve looked so much for this but can’t find anything that works. The closest post I found was this > https://generatepress.com/forums/topic/how-to-make-equal-height-columns/ but it didn't work!

All I want to do is to make each card/container the same height with the content inside spaced so the buttons line up at the bottom with the other card. The coloumns have an image at the top then post title, then excerpt, then a button

Many Thanks!
