Remove border from card with CSS?

[jockebq]

I am trying to remove the border with card-mod CSS. But I cannot manage to do it. I know it is border-style: none;
Tried using
:host { border-style: none!important; }

And read the readme, but there is no border --lc customization.

Any idea how to do it?

Try to use --ha-card-border-color or --divider-color to change color of border
