Common Card Size

Hi Guys,
This is a bit of a strange one but someone smarter than me might know the answer!
I have a row with 3 columns and each column contains a card which have some content in them. When I re-size the browser the card heights change to adapt to their new width which is fine. As the content in each card isn’t exactly the same size, one card will often have a larger height than the others.

Does anyone know of a way that I can have all 3 cards share the same height? i.e. when the browser is re-sized, they all get set to the same height?

I guess I could use the min-height in the style but I was hoping there would be a nicer way to do it!
