Is it possible to have a linear progress indicator on the bottom or top border of a Material-UI card? i.e. the full width of the card, no padding. I think I've seen this used in some Google apps (though I can't find it anywhere now I'm looking).
If not, is there a better way to indicate a card is loading?
In my case, the card has some content and is waiting for a live response from a support agent, so it's intended to indicate the card will get additional information when it is ready.
