Hello guys, I am trying to design a water tank so that bubbles appear inside the card , but no bubbles appear even though the code is correct.
can you help me
type: custom:mod-cardcard: type: custom:fluid-level-background-card card - Pastebin.com

  1. In my example bubbles are shown:
        type: custom:fluid-level-background-card
        card:
          type: glance
          entities:
            - entity: sun.sun
              name: Beer level
        entity: input_number.test_level_1
        fill_entity: input_boolean.test_boolean

2. Your code contains LOTS of unrelated stuff like card-mod. Suggest you to MINIMIZE it as much as possible to demonstrate the issue. Just a quick look (could be unrelated to your main issue): card_mod keyword is missing; the “extra_styles” option does not belong to fluid-card.
3. Then please do not post a link to a code - post a SHORT code right here in the thread (formatted as a code).
