Button Card State Font Sizing?

[toxic laurel]

still very new to HA trying to customise dashboard to fit my NSpanel and the default fonts on most cards are too small .
Cant seem to workout how to change the sizing of the state font?
trying to work it out by using this

You can try:

card_mod:
  style:
    .: |
      ha-card {
        font-size: 8px !important;
      }
      .state{
        font-size: 20px !important;
      }
