šŸ”¹ Card-mod - Add css styles to any lovelace card

Well, at least using one more syntax gives us more flexibility!

just a thought, but would it all be possible have the overview posts separated into a Community Guide of sorts. No discussions there, those are done here, simply all posts like @Ildar_Gabdullin did for the various cards and stylings.

Right now, we need to go back and forth in this thread to find these (or save them locally, as I didā€¦). I think it would be very beneficial to all of us to have them on display permanently.

With the separated/dedicated community guide, checking how to style a badge, or a font-size for Entities card would be a breeze.

I would appreciate guidance for suppressing the display of the entire toggle button in an Entities card.

Iā€™ve tried enough things to confirm I donā€™t have a good grasp of the core concepts (i.e. seems straighforward in theory but not in practice). For example, I tried this but it doesnā€™t work:

type: entities
entities:
  - entity: input_boolean.test
show_header_toggle: false
style:
  ha-entity-toggle:
    $: |
      ha-switch {
        display: none !important;
      }

The toggle button is within a shadow-root and, based on my limitation understanding, that implies more complexity in how to define the item I wish to act on.

But this plug-in is nowhere to be found in HACS ?
Is a custom repository needed to install it ? If so, whatā€™s the URL ?

Hi.
Thanks for all your work and help here!

Iā€™ve searched for a few days but cant seem to figure out how it actually works.
Iā€™ve also read that there might be problems with picture elemts cards, but there was a work around?

I have 2 icons, which actually should show a debug boolean state (removed to simplify) but I just want to change the color depending on on/off state and the only way to do it seems to be card-mod.

elements:
  - icon: 'mdi:android-debug-bridge'
    title: Debug
    type: icon
    style:
      '--mdc-icon-size': 40px
      color: 'rgba(255, 0, 0, 0.6)'
      background-color: 'rgba(3, 169, 244, 0.6)'
      border-radius: 50%
      top: 35%
      left: 40%
      padding: 10px 10px 10px 10px
  - icon: 'mdi:android-debug-bridge'
    title: Debug
    type: icon
    style: |
      hui-icon-element {
        color: blue;
      }
image: /
type: picture-elements

But Iā€™m unable to make the second icon use any of the attributes of the first icon.
Iā€™ve also tryed the debug method of my browser and found some elemts names but they modify colors of the entire page.

<hui-icon-element class="element" style="--mdc-icon-size:40px; color: rgba(255, 0, 0, 0.6); background-color: rgba(3, 169, 244, 0.6); border-radius: 50%; top: 35%; left: 40%; padding: 10px;"></hui-icon-element>

Any help apreciated

Uh, Maybe I can hepl here!

I just made it work:

In Hacs, under Frontend, press ā€œ+ EXPLORE & ADD REPOSITURIESā€ and search for card-mod. Think thats how I made it work!

Found it :+1: Thank you!

NOTE:
Do not forget to add a "card_mod:" keyword before "style:" (new in card-mod 3).

Thank you! I think I now understand why the many things I have tried all failed to work.

If the Entities card contains multiple entities, is there a way to make the style apply to all of them? Or does it have to be repeated for each one separately?

Please check here:

There are examples with common style for all entities.
Note that you can specify a common style and then override it for some particular entity like here:

type: entities
title: 'Changed color'
style: |
  ha-card {
    color: blue;
  }
  ha-card .card-content {
    color: red;
  }
entities:
  - entity: input_boolean.test_boolean
    name: Inherited color
  - entity: sun.sun
    name: Inherited color
    secondary_info: last-changed
  - entity: sun.sun
    name: Changed color
    secondary_info: last-changed
    style: |
      :host {
       color: cyan;
      }

ŠøŠ·Š¾Š±Ń€Š°Š¶ŠµŠ½ŠøŠµ

The issue I am experiencing is that if I move the style block to the left, so it applies to all entities, it fails to work (even for just one entity).

type: entities
entities:
  - entity: input_boolean.test_boolean
style:
  hui-generic-entity-row:
    ha-entity-toggle:
      $: |
        ha-switch {
         display: none;
        }

Does the reference within the style have to be modified?

Please check this:
ŠøŠ·Š¾Š±Ń€Š°Š¶ŠµŠ½ŠøŠµ

type: entities
title: 'Checkbox: hidden'
show_header_toggle: false
entities:
  - entity: input_boolean.test_boolean
  - entity: input_boolean.test_boolean
style:
  hui-toggle-entity-row:
    $:
      hui-generic-entity-row:
        ha-entity-toggle:
          $: |
            ha-switch {
             display: none;
            }

"hui-generic-entity-row" is inside shadow-root of "hui-toggle-entity-row", so you must specify it.
And you mustnā€™t if the style is for a particular entity (in short, you are already inside the shadow-root).

Colored checkbox:

NOTE:
Do not forget to add a "card_mod:" keyword before "style:" (new in card-mod 3).

Thanks for all your posts, they have been quite informative!

But I think Iā€™m at a state where you were too in the beginning. Not grasping the whole idea and not being able to read a good toturial.

Is the idea that you start your tree in the top layer, and write in code your way down untill you get to the eneioty you want changed?
And that $: is to change into those shadow-y-thing-y?
And the dot-colon-space-pipe >> .: | << is for when theres actually coming style code?

Yes, I am trying to use this approach.
Also, in this thread there was at least one more method described by the developer of card-mod (look at his posts, you will find the needed one).

It was described in the GitHub (GitHub - thomasloven/lovelace-card-mod: šŸ”¹ Add CSS styles to (almost) any lovelace card).
$: is used to go inside shadow-root of some element.

.: is used to go inside some element (not shadow-root) - see GitHub.

I am not 100% sure but I think that the pipe | is used to break a line before styles:

    style: |
      :host {
        color: red;
      }
or
    style: ':host { color: red; }'
    style:
      hui-generic-entity-row:
        ha-entity-toggle:
          $: |
            ha-switch {
              --switch-unchecked-button-color: yellow;
              --switch-checked-button-color: red;
            }            
or
    style:
      hui-generic-entity-row ha-entity-toggle:
        $: 'ha-switch { --switch-unchecked-button-color: yellow; --switch-checked-button-color: red; }'

The means that the pipe must be used ONE time after the LAST colon.

The example:

type: entities
title: Using pipe
show_header_toggle: false
entities:
  - entity: input_boolean.test_boolean
    name: colored text
    style: |
      :host {
        color: red;
      }
  - entity: input_boolean.test_boolean
    name: colored text
    style: ':host { color: red; }'
  - entity: input_boolean.test_boolean
    name: colored button
    style:
      hui-generic-entity-row:
        ha-entity-toggle:
          $: |
            ha-switch {
              --switch-unchecked-button-color: yellow;
              --switch-checked-button-color: red;
            }            
  - entity: input_boolean.test_boolean
    name: colored button
    style:
      hui-generic-entity-row:
        ha-entity-toggle:
          $: 'ha-switch { --switch-unchecked-button-color: yellow; --switch-checked-button-color: red; }'
  - entity: input_boolean.test_boolean

Iā€™ve been off here for a bit. Are there any posts that havenā€™t already been answered?

How can I reach the first div in order to add style elements? I tried a few searches but Iā€™m not even sure what to search for. I scanned a number of Ildar Gabdullinā€™s posts as there are many examples but except for going into shadow roots I couldnā€™t find the answer for this.

Iā€™m pretty sure you donā€™t need shadow-rooting for that. What happens without shadow-rooting? Could you also specify your whole intentions?
