Keep both boxs same height

Hi

With enfold its great how everything is trurly responsive :)

I am wondering though if there is a way to ensure both text boxs remain the same height ? If you go to

And underneath the slide show, there are two images, under that there are 2 text boxs. I used code block for this and embedded the code for special headers etc They are both of varying heights though and it would look better if they were the same height. I notice when I play with the browser width and reduce the screen width that then the smaller box can become the taller box.

I am wondering if there is any css to ensure both stay the same height? Possibly min height? I don’t want to compromise on it being responsive though
