🔹 Card-mod - Add css styles to any lovelace card

[Ildar_Gabdullin]

Styling 'custom:multiple-entity-row’

Intro:
Let’s call the “left” entity as the “main entity” (for which we may display a state on the last right column), all right entities - “secondary entities”.
For secondary entities you may use a “styles” option (no card-mod required) to set a color and some other CSS properties:

    entities:
      - entity: sensor.xxxxxxx
        styles:  ### styling a “state” string
          width: 80px
          text-align: left
          color: red

or

        styles:
          --paper-item-icon-color: red  ### styling an icon

or

        styles:
          --secondary-text-color: red  ### styling a header

Same approach may be used to style the main entity’s state – except changing the main icon.
Using the “styles” option is a good choice if styles (colors etc) are static. If they are dynamic (depend on some conditions) then you should either place the whole row inside config-template-card (supports JS) or use card-mod (supports jinjia2).

              opacity: 1;
            }
          }

If you need a conditional animation - see these examples for rotation:
a) rotation ON/OFF:

          state-badge  {
            color: orange;
            {% if ..... %}
            animation: rotation 0.5s linear infinite;
            {% endif %}
          }

b) various speed:

          state-badge  {
            color: orange;
            {% set SPEED = .... %}
            animation: rotation {{SPEED}}s linear infinite;
          }

Update (20.05.22):

1. This animation does not work on iOS 15.4.1, iOS 12.5.5 & MacOS:

          @keyframes resizing {
            0% {
              --mdc-icon-size: 10px;
            }

Use this variants instead:

  - entity: sun.sun
    name: resizing (height, width)
    icon: mdi:radio-tower
    card_mod:
      style:
        hui-generic-entity-row $ state-badge $ ha-state-icon $ ha-icon $: |
          ha-svg-icon {
            animation: resizing 1s linear infinite alternate;
          }
          @keyframes resizing {
            0% {
              height: 10px;
              width: 10px;
            }
            25% {
              height: 15px;
              width: 15px;
            }
            50% {
              height: 20px;
              width: 20px;
            }
            75% {
              height: 26px;
              width: 26px;
            }
            100% {
              height: 32px;
              width: 32px;
            }
          }
  - entity: sun.sun
    name: resizing (scale)
    icon: mdi:radio-tower
    card_mod:
      style:
        hui-generic-entity-row $ state-badge $ ha-state-icon $ ha-icon $: |
          ha-svg-icon {
            animation: resizing 1s linear infinite alternate;
          }
          @keyframes resizing {
            0% {
              transform: scale(0.3,0.3);
            }
            25% {
              transform: scale(0.7,0.7);
            }
            50% {
              transform: scale(1,1);
            }
            75% {
              transform: scale(1.15,1.15);
            }
            100% {
              transform: scale(1.3,1.3);
            }
          }

Animation using custom properties is promised to be added in Safari 16.

2. This animation glitches on iOS 15.4.1, iOS 12.5.5 & MacOS (glitches affecting a whole card):

          @keyframes flipping {
            0% {
              transform: rotateX(0deg);
            }

No solution for this so far.
The animation may work OK but also may cause glitches. This is Apple, sorry.

Hello,

I’m trying to change the size of the text on a light card and I apparently don’t understand enough css to do it. Below is what I have and I’ve tried multiple variants, but I can’t seem to get it to work.

type: light
entity: light.kitchen_lights
style: |
ha-card {
--name-font-size: 10px;
}

                font-size: var(--mdc-typography-body1-font-size, 1rem);
              }
            .: |
              .info.pointer {
                color: red;
                font-size: 8px;

    name: "!!!! Size for value (w/o sec_info) !!!!"
    card_mod:
      style:
        hui-generic-entity-row $: |
          .text-content.pointer:not(.info) {

                font-size: 20px;
                color: green !important;
              }

Note that for setting a “standard” font size I had to use a "font-size: var(--mdc-typography-body1-font-size, 1rem)" in the "Size for name only" case, I do not think it is good (kind of ‘hard coding’), and may be there is a better solution…

Another option for changing the title’s font-size - using a "--ha-card-header-font-size" variable:

type: entities
title: 'Style: title font-size'
entities:
  - entity: sun.sun
style: |
  ha-card {
    --ha-card-header-font-size: 35px;
  }

How to change a font-size for a "button" row:

type: entities
title: Size for button
entities:
  - type: button
    name: Standard size
    tap_action:
      action: call-service
      service: homeassistant.update_entity
      service_data:
        entity_id: sun.sun
  - type: button
    name: Standard size
    tap_action:
      action: call-service
      service: homeassistant.update_entity
      service_data:
        entity_id: sun.sun
    card_mod:
      style: |
        :host {
          --mdc-typography-button-font-size: 20px;
        }

Can you use triple backticks instead of single ones?

[wraith1385]

Sorry, apparently I was not paying close enough attention to that warning that popped up. Here ya go:

type: light
entity: light.kitchen_lights
style: |
  ha-card {
    --name-font-size: 10px;
  }

[wraith1385]

What I’m actually trying to do is shrink everything on the light card so that it is roughly the size of a custom button card, but I’m unsure if I need to do that piecemeal or if it can be done with an overall piece of code.

[Ildar_Gabdullin]

Actually, you can try something like this:

Card-mod - Add css styles to any lovelace card

How to change a font-size for Entities card: [изображение] type: entities title: Size for title style: | ha-card .card-header { font-size: 35px; color: red; } entities: - entity: sun.sun name: Standard size secondary_info: last-changed - entity: sun.sun name: Size for whole row secondary_info: last-changed style: | :host { font-size: 25px; color: red; } - entity: sun.sun name: Size for name & secondary_info secondary_inf…

Cannot check it with light since I do not have any lights so far.

Is it possible to adjust the card size with card mod? Just installed the card mod but still trying to figure out how to adjust the card size.

Thanks in advance.

I have a light card that capable of brightness, but I don’t need the control of brightness, how to hide the big circle that adjust brightness in the light card?

If you’ll never use it, I think you can remove it via the customization panel by setting the supported stuff to 0.

Sorry I should be more clear, I mean I don’t adjust the brightness for this light in this card. It is in the first page of lovelace ui that I used it to quickly turn stuff on/off. I also have it configured in another page so I can adjustment brightness over there.

round-slider {
  visibility: hidden !important;
}

Why do you think it’s cardStyle? It’s documented that you use style, not cardStyle.
