While icon_height: 60px works icon_width: 60px does nothing. Any help would be very much appreciated.
I have had a search of the forum and have not managed to find a topic that could help me. I’m sure this is a problem with my knowledge rather than anything else…
No, the width of cards is controlled by the number of panels that you have as well as the size of your screen.
Also, you should note that icon_height does not control the height of the button. It controls the height of the icon.
If you want square buttons, you should move towards the custom:button-card. It has much more control over what you can do. One of the options for custom button card is to retain an aspect ratio.
