Feature request: native transparent / card background option

[khurer78]

First of all, thanks for this excellent card — it's incredibly feature-rich.

Request: Could you add a native option to control the card background, e.g. a transparent: true toggle or a card_background setting?

Why: Right now the only way to make the card blend into a dashboard (transparent background, no box-shadow/border) is via card-mod. This works in simple cases, but it's unreliable on this card specifically:

• With animate_graph: true, live state updates and date_picker_group sync, the card re-renders its ha-card element frequently and drops the injected card-mod styles. The result is that transparency flickers — sometimes applied, sometimes not.
• Wrapping the card in mod-card gives stable transparency, but then the visual editor is no longer available for the inner card.
• card-mod's prepend: true keeps the editor but the style doesn't reach the right element on this card, so transparency isn't applied at all.

So there's currently no way to have both a working visual editor and stable transparency.

A native background/transparency option would solve this cleanly, since the card would render its own background correctly on every redraw.

Environment: Home Assistant 2026.6.x, card v3.11, card-mod v4.x, viewed on iPad (Kiosk Mode) and iPhone.

Thanks for considering it!
