all buttons in 3 columns resting a bottom of column, all at same height?

How to I get bottom text or button to rest on the bottom of column, regardless of height of column. As of now, you see Button for 1, Button for 2, etc. They are all different heights depending on how much text is in column.

I need to get that specific feature (Button 1, 2, etc) to rest on bottom of column.

This makes sense if you have 3 columns (in a row) with payment buttons, or CTA links, at the bottom of each column. Anyone would want these buttons on bottom of column, not floating as they are on my site now.

I tried inserting a new instance of the SO editor below each column, and putting button codes in these new editors, but that didn’t work. Buttons still floated instead of resting on bottom of column.

Thanks for any suggestions on how to achieve this.
