[Help]: Hiding the border/frame inside the button card

[Vikaspogu]

I am using the Lovelace thermostat card. When I apply the frosted theme, the border/frame becomes visible on all the button card templates from Lovelace Minimalist. I am a newbie and don't have much experience, so any pointers to fix it would be appreciated!

You can try to apply this fix using the cardmod on the card and apply it to the whole card, it will make it 100% border less but it should look better than this - or apply this cardmod to only certain buttons on the card.
