Dynamically Size Divs

On the home page of my site, I have a collection list for this company’s services. The issue I am having is that, on different screen sizes, some paragraphs under the pictures may have more lines than others. Is there a way to make the box size scale dynamically so that they all are always the same size? Below is a screenshot of the issue and my read-only link.

That is perfect, thank you!
