Card Mod Issues

Configuration Frontend
1

I have some long standing Lovelace cards where the card_mod styles have just stop working. This one is not actually one of those but one I have been toying with to see where the problem is. This is very basic and the card_mod portion of it is copied directly from the card_mod repository. I have tried this with the entity, entities, button (the original problem child), and custom-mushroom-entity-card.
The below code uses the entities card to keep it simple but the font_size: ( or font-size:) has no effect nor does the color: style.

type: entities
entities:
  - entity: binary_sensor.motion_1_motion
    show_name: false
    show_icon: true
    card_mod:
        style: |
          ha-card {
            font-size: 40px;
            }

These options do not belong to Entities card.

This code will probably not work - you will have to address a particular element in DOM path.

Btw, there is a dedicated card-mod thread - no reason to create a separate thread for these “issues”. Suggest to ask there.
