Entities card "run" button text drop shadow

Hi,

I have an entities card with multiple entities and two of them are scripts with a “run” button option. I wish to add a drop shadow to the “RUN” text inside the button, not the button itself, using card-mod, but i don’t know to make reference to that text in particular to add the css style for the drop shadow.

Script and card screenshot below.
Thank you.

  1. No need to post a code for the whole card, a code for these 2 rows in Entities card is enough.
  2. How to style a “button” entity-row: go to huge card-mod thread → 1st post → link at the bottom → styles for Entities card.
