I’m trying to get a couple images to be centered and stacked when viewing on mobile but side by side on desktop.

MOBILE:

As you can see, the images are centered when the email is viewed on desktop but on mobile, it is aligned somewhat to the left. Is there a way to have the images center aligned? Thanks!
