How to add box shadow to the Turbo theme using CSS?

[Kjankko-US]

Hi,

I have a "text-columns-with-images" -section on my (development) store.

I want to add some CSS to create box shadows.

Question: What is the CSS class for that section?

I want to add a shadow like this:

box-shadow: rgba(0, 0, 0, 0.24) 0px 3px 8px;
