Image Overlay Bric by Norm - Description Field sizing

First time using this Bric I purchased a few weeks ago. The only problem I am having so far is with the Description text field. I am using that field to paste in a short Bio for an employee. It works fine on desktop width, but on iPad and iPhone it crops off the top/bottom of the paragraph? Is there a way I can reduce the font size/line spacing for the Description field for smaller screens?

The amount of text in the smaller screens also causes the Button field to vanish as there is no room for it to display.

I was hoping that the content would scale down automatically to fit, but I guess not?

Use class: desc
You should be able to resize the description at each breaking point after that.

Thanks for the reply! I am still new at using Blocs (first site actually) so I am not. sure exactly how to do that? I created a new class .desc in the class manager, but how do I attach the class to the element?
