Background Color

Please tell a newbie the simplest code for changing the background color of a tile card.

Install card-mod and add this code (untested):

type: tile
…
card_mod:
  style: |
    ha-card {background: red;}

cards:

  • features:
    • type: light-color-temp
      type: tile
      card_mod: null
      style: |
      ha-card {background: red;}
      entity: light.den_table_lamp
      features_position: bottom
      vertical: false
      show_entity_picture: true
      color: primary
      hide_state: false
      state_content: brightness
      name: Table
      view_layout:
      grid-area: row1-2

foursome reasons my indents did not copy

Use the feature underlined in red to post your code

Seems that the card-mod code is not properly indented. Check card-mod docs for a correct syntax.
