You could try defining the icon sizes as percentages rather than fixed pixel sizes but I don’t think that will help. The card does not scale the icons relative to the screen size but relative to the original icon size. I gave up on the picture element card. It’s next to impossible to make it look good on a large pc screen and a small mobile one.
I have tried percentages, but the problem with which I find is that for the same icon.
I have to use different % to get the same size between them (for example the circles) And I do not know if it is normal or not doing something right, but it has no logic.
I have tried to learn about how to make a custom card because in them if rescaling works, but it is very complicated for me. I hope that these things are taken into consideration to correct in future versions
