We are a small nonprofit using Pardot for our emails. We recently tried to build a template based on Pardot's responsive 2 column template. On the 2 column section, the image and text shows as centered on laptop/desktop. But on mobile, the columns stack (which is good) but all render as left aligned. It would look more professional if the stacked 2 columns on mobile appeared centered. Any tips on solving this in our template? I imagine the answer is some type of CSS, but we don't have access to a CSS developer.
