In creating new dashboards for my HA installation some of the entity sensor values appear in text that is too large. I created a test card and have had some success in controlling the color and font-size but while I can change the text-size of the card name, I cannot seem to change font-size of the displayed entity value. The color changes okay but not the size.

ha-card

.header .name
{font-size: 20px; color:green}
type: entity
entity: sensor.sonoff_1000bdxxxx_temperature
