Why does the outer card_mod applied to the entities card also affect the child elements (here: simple-clock-card GitHub - fufar/simple-clock-card: Simple clock card for Home assistant lovelace)?
border-with: 0px; is not respected here 
type: entities
title: 🕒 Uhrzeit
state_color: true
show_header_toggle: true
entities:
- type: custom:simple-clock-card
use_military: true
hide_seconds: false
font_size: 1.5rem
paddingLeft_size: 10px
paddingRight_size: 10px
paddingTop_size: 10px
paddingBottom_size: 10px
card_mod:
style: |
ha-card {
letter-spacing: 1px;
border-width: 0px;
#padding: 3px;
margin-left: -5px;
#text-align: right;
#margin-top: -10px;
}
card_mod:
style:
.: |
ha-card {
border-width: 1px;
}
Obviously I want to remove the border from the inner card.
