equal hight featured areas

I would like to have the featured areas having equal heights, button to the bottom.

Flexbox could maybe do it, for now I’m using a bit of jquery. Getting the height of the h3 and the first p and setting them all to the same height.

I noticed that I can’t paste the javascript code into the option ‘Custom jQuery – Front End’. It gets all escaped (\’ instead of ‘ ) and it adds \n as well
