Reduce Card Header Size

I’m new to Home Assistant and on a steep learning curve and in need of some help please.

I have this sensor card with large font setup but the header is cutting the text.

Here is the code-

graph: line
type: sensor
entity: sensor.heating_hot_water_tank_735
name: Hot Water Tank
style: |
  ha-card
   {
  --accent-color: red;
    }
  .header .name {
  color: #959595;
  font-size: 12px;
  font weight: bold
  }
  .header .icon {
  color: #red;
  --mdc-icon-size: 28px;
  }
  .info .value {
  color: white;
  font-size: 68px;
  font-weight: light
  }
  .info .measurement {
  color: white;
  font-size: 12px;
  }
detail: 2

Is there a way the free header space can be reduced?

Thanks Steve
