not this card in particular, but in below link, you find another ink to “custom-updater” , … and in regards to the problems people had/have i see in " Lovelace: Home Feed Card" … i made my own “assumption” , i would never start to use it , sorry but that’s my opinion … when was the Last Update from developer of this Card ? , that’s a part of my Assumption
PS: Sorry i mixed up the 2 cards in regards to “updates” , but still don’t find any “options” for divider.
But i do see that it uses “entities” , and it should in this case be there, if possible
entities:
- entity: your.entity
name:
something:else
- type: section
* i dont know which options CSS there are for defining the "section"
but there is - type: devider
which have more options, maybe your Theme vil apply what you already have, as it's within "entities"
