Ok so I realized the issue was that I forgot to add :item true to the container items. That made the overriding go away. Now it's just a visual issue with flex box settings. I'm trying to have the app bar centered with the card container and the cards spaced with "space-around", but that setting doesn't change it for some reason.

But the cards are being arranged with "flex-start" so it's left justified

Figured it out
