Generic Card

The generic-card module applies to all ha-card elements in Lovelace. This covers most cards in Lovelace except for functional cards like conditional or entity-filter.

no_card

The no_card option, when set to true on a card, will hide the background of the card. This is especially useful when embedding cards in entity rows.

type: entities
no_card: true
entities:
  - entity: light.bedroom

canary_style

The canary_style option can be used to apply a map of CSS styles to a card. Note that it must be a mapping, not an array or string.

type: entities
canary_style:
  color: lightblue
  background-color: black
entities:
  - entity: light.bedroom

canary_theme

The canary_theme option can be used to apply a theme to a card, similar to how the theme option works except with wider support. It can also be used as another way to apply CSS styles to a card. Note that if you change a theme this will not update when you reload themes, you will need to refresh the page.

The canary_theme option works slightly different to how Home Assistant's theme option does, in that it only adds the CSS styles from the theme to a card.

type: entities
canary_theme: midnight
entities:
  - entity: light.bedroom
