Help - Text size different on refresh

Hey. I have inconsistent renderings of the same cards between refreshes

I am using FKB to view a dashboard on my tablet.

In the dashboard I have used card-mod to resize the text to 30px. When I view the dashboard on my laptop, using chrome, the text is consistently 30px between refreshes. However, when I refresh the dashboard on my tablet (FKB), the text sometimes renders at 30px and sometimes at the original size. There doesn’t seem to be any pattern for why it renders at one or the other. Any ideas of what is going would be gratefully received.

  1. You are using a card-mod code which is not obliged to work. Go to the main card-mod thread → 1st post → styles for Entities card for a proper code for changing fonts.
  2. Your clients may have different browsers which behave differently - especially in case of an incorrect code.
  3. Suggest to ask all card-mod related questions in the mentioned card-mod thread instead of creating 100500th new thread.
