How to Center Fallback Photo on Mobile

Hello! I have a row with a video and a fallback photo set. The video doesn’t load on mobile, but the fallback photo does. It is just not centered. How do I center the fallback photo for mobile?

I saw another post suggesting " The best solution I can come up with is for you to open up the settings for the Row/module in question and in the Advanced tab > Responsive Layout, select Large Devices only.

Then add a second Row/module for your background image and in the Advanced Settings > Responsive Layout, select Medium & Small Devices Only."

But I don’t know how to do that either. Is that the “breakpoint” settings? Anyways, I tried that and it didn’t work. I must be doing something wrong.

Thanks in advance for your help.
