size of card

[GeoBau]

I want to make the card smaller

  style: |
    ha-card {
     font-size: 10px;
     padding: 0px !important;
     marging: 0px !important;
     --mdc-typography-button-font-size: .725rem;
    }

that influences the font-size in the boxes. But I can't find a way to change the fontsize of the day's text.
can you give me hint what to do? thanks

I have 2 HAs running.
the size is inside the class 'label'.
In one of them this is changing the size (core 2024.6.4 und OS 12.4)

card_mod:
  style: |
    ha-card {
     padding: 1px !important;
     --mdc-typography-button-font-size: .725rem;
    }
    .label {
      font-size: 1.2rem !important;  # Adjust the font size as needed
    }
