Unable to get widget_style: "background-color:inherit;" working for iconsensor

I am running Hass.io on Raspberry Pi. I am trying to get your Weather.dash implemented on my Hass.io. I can get “temperature_today” enititysensor to show as expected as well as make any changes to widget_style: "background-color: " where as I just could not get iconsensor “weather_icon_today” to respond to widget_style: "background-color:inherit; What am I doing wrong? Please advise.

Figured out. Explicitly using “skin” argument solved my problem.
