Site Origin – How to keep text boxes same width/height?

Hello,

I realize this might not be the correct forum, but I’ve tried posting in SiteOrigin and a few others without any luck. I’m hoping someone here might be able to help me.

I’m using Site Origin on my home page and I’ve made 4 rows with 3 columns on each row. I’ve outlined each text box in black. I’m trying to figure out how to keep each content box the same size when the window size changes. When I make my window smaller the content boxes get taller and skinnier and become uneven, and when I make my window larger the boxes get wider and shorter. I need the size of the boxes to all stay the same width and height while being proportionate to the size of the window. Hopefully, that makes sense? Please feel free to take a look at fedfis.com/newsite.

Any advice on how to fix this would be much appreciated.
