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

yes, I’ve just discovered we can put most anything there, a simple null works too :wink: Best leave it out completely then, I don’t really like useless code.

about the entity in the view:

I tried it on a simple button:

  - name: Sonorisation
    entity: input_boolean.notify_system
    show_name: true
    icon: mdi:speaker
    type: custom:button-card
    card_mod:
      style:
        <<: *exist

using the same test trick (delete the last character of the entity, still shows the card)

maybe this should be done from within the button-card, but for educational purposes of card-mod Ireally like to have a go at it here too.

because, and here comes the full monty, if we can figure it out, it needs to be combined with a rather huge card_mod :wink:

maybe even that should be done in the button card with the extra_styles option I now realize.

  - name: Sonorisation
    entity: input_boolean.notify_system
    show_name: true

There is smth strange with "is_state(config.entity,'unknown')" for "custom:button-card":
Five buttons:
1 - with "is_state(config.entity,'unknown')" - the card is still displayed for wrong entity;
2 - with "is_state('THIS_WRONG_ENTITY', 'unknown')" - the card is still displayed for wrong entity;
3 - with "states(config.entity) in ['unknown']" - the card is NOT displayed for wrong entity;
4 - always "display: none" - the card is NOT displayed;
5 - the card w/o style.


The code:

type: vertical-stack
cards:
  - type: entity
    entity: sun.sun
  - name: Sonorisation (with style 1)
    entity: input_boolean.test_boolean__non_existing__
    show_name: true
    icon: mdi:speaker
    type: custom:button-card
    card_mod:
      style: |
        :host {
          {% if is_state(config.entity,'unknown') %} display: none !important; {% endif %}
        }
  - name: Sonorisation (with style 2)
    entity: input_boolean.test_boolean__non_existing__
    show_name: true
    icon: mdi:speaker
    type: custom:button-card
    card_mod:
      style: |
        :host {
          {% if is_state('input_boolean.test_boolean__non_existing__','unknown') %} display: none !important; {% endif %}
        }
  - name: Sonorisation (with style 3)
    entity: input_boolean.test_boolean__non_existing__
    show_name: true
    icon: mdi:speaker
    type: custom:button-card
    card_mod:
      style: |
        :host {
          {% if states(config.entity) in ['unknown'] %} display: none !important; {% endif %}
        }
  - name: Sonorisation (with style 4)
    entity: input_boolean.test_boolean
    show_name: true
    icon: mdi:speaker
    type: custom:button-card
    card_mod:
      style: |
        :host {
          display: none !important;
        }
  - name: Sonorisation (w/o style 5)
    entity: input_boolean.test_boolean
    show_name: true
    icon: mdi:speaker
    type: custom:button-card

its the !important that is making it work:

    card_mod:
      style: |
           :host {
             {% if states(config.entity) == 'unknown' %} display: none !important{% endif %}
           }

works too.
Always understood that its considered bad practice using the !important, so I’ve never done that, anywhere in the config yet .

as said, we should probably use the button card options itself:

    type: custom:button-card
    styles:
      card:
        - display: >
            [[[ if (!entity.state) return none; ]]]

note to self: add this to button_card_templates.yaml :wink:

This is not the issue.
The issue is that is_state(config.entity,'unknown') not working as well as is_state('my_wrong_entity_id,'unknown').
In my opinion - this is a BUG.

Have a look at this example:
image

type: entities
entities:
  - entity: sun.sun
    card_mod:
      style: |
        :host {
          {% if is_state('input_boolean.test_boolen','unknown') %} color: red; {% endif %}
        }
  - entity: sun.sun
    card_mod:
      style: |
        :host {
          {% if states('input_boolean.test_boolen') in ['unknown'] %} color: red; {% endif %}
        }
  - entity: sun.sun
    card_mod:
      style: |
        :host {
          {% if states('input_boolean.test_boolen') == 'unknown' %} color: red; {% endif %}
        }

The 1st style does not work for some wrong entity, the 2nd & 3rd do.
So this is a common behaviour, not only for the "custom:button-card".

And let’s look at the “Templates” window:

Asked a question here and got a reply from Petro.


Here is my test with your style - 3 buttons:
1 - wrong entity
2 - wrong entity + your style
3 - valid entity

type: vertical-stack
cards:
  - name: Sonorisation (wrong entity)
    entity: input_boolean.test_boolean___XXX
    show_name: true
    icon: mdi:speaker
    type: custom:button-card
  - name: Sonorisation (wrong entity + style)
    entity: input_boolean.test_boolean___XXX
    show_name: true
    icon: mdi:speaker
    type: custom:button-card
    styles:
      card:
        - display: >
            [[[ if (!entity.state) return none; ]]]
  - name: Sonorisation
    entity: input_boolean.test_boolean
    show_name: true
    icon: mdi:speaker
    type: custom:button-card

Seems that this style does not work…
"entity.state" returns a state. If the entity is undefined then it causes an error.
As for me, I do not know how to check whether an entity is valid or not in the "custom:button-card".

Sorry for an off-topic, this should be discussed in the “custom:button-card” thread.

I try to apply some custom style to the title area of a (entities) card. Unfortunately this isn´t working, all style changes are “only” applied to the card below the title area.

How to modify a card´s title? Basically I just want to center a cards title instead of having it aligned left.

Do I need to fake a title somehow to modify it or is there another, more easy way?

yes it checks for a state, and works in my setup. You can even do this (button_card_template):

exist:
  styles:
    card:
      - display: >
          [[[ if (!entity) return none; ]]]

and in a card:

  - name: Sonorisation
    template: exist
    entity: input_boolean.notify_syzzzz
    show_name: true
    icon: mdi:speaker
    type: custom:button-card

and (they both) even work if you take out the full entity:

  - name: Sonorisation
    template: exist
#    entity: input_boolean.notify_system
    show_name: true
    icon: mdi:speaker
    type: custom:button-card

or:

  - type: custom:button-card
    template: exist
    entity:
    name: Sonorisation
    show_name: true
    icon: mdi:speaker

back on topic: Thomas replied to the issue I created for this, but though the format of that template seems ok, (and I use that elsewhere in the config templates successfully) I can not get it to work in the card_mod.

Look at the 1st post, there is a link to to another post with many styles for the Entities card.

I did so already. But couldn’t find anything related to title :frowning:

It is described there, try using this:

style: |
  ha-card .card-header {
      ...
  }

I’m searching for a solution with card-mod to get cards with better look.
The first step is a markdown card,
font-size is to small, text-align should be center.
I tried different things, but nothing works in browser.

Can somebody help me to understand the working of this mod?

On my phone, but have a look at this post of mine to see how I styled a markdown table. Should get you going. Then, it always helps to post at least one of the things you tried — then we can see a real attempt and it gives people some YAML to work with you.

I tried this and styles with ha-markdown, ha-markdown-element and p, but there were no changes.
In the Inspector i can enter this and it works.

cards:
  - type: custom:layout-card
    layout_type: custom:vertical-layout

                        margin-bottom: auto;
                      }

Can anyone help me changing the line-height for all card titles inside a custom:grid-layout ? I’ve tried alooot of things but I’m totally lost …

I tried to change a cards title. Tried for over one hour and something.

It seems to simply be impossible. I tried every approach, last two promising were

      }

Changed exactly nothing. Summary: changing card titles is impossible. Everyone trying to do this on a per card basis: don´t waste your time (like I did).

What do you want exactly?
Could you provide a picture describing your intentions?

I want to center a card´s title. Nothing more, nothing less :man_shrugging:

Desired (mock-up):

Mission impossible according to what I´ve gone through so far.

+++ UPDATE +++
Solution provided by @MaestroMetty at 🔹 Card-mod - Super-charge your themes! - #864 by MaestroMetty.

This is not a solution. This is just another approach.

Okay :slight_smile: Well it´s working (basically) for me. Even the need for using the custom:mod-card is not nice but I can completely live with that.

Would you propose another approach for the same result?

Here it is, use any alignment:

type: vertical-stack
cards:
  - type: entities
    title: Some title (+card-mod)
    card_mod:
      style: |
        ha-card .card-header {
          border: 3px dotted magenta;
          padding: 0px;
          display: unset;
        }
        ha-card .card-header .name {
          color: red;
          text-align: right;
          font-weight: 1000;
          letter-spacing: 3px;
        }
    entities:
      - entity: sun.sun
      - entity: sun.sun
      - entity: sun.sun
  - type: entities
    title: Some title
    entities:
      - entity: sun.sun
      - entity: sun.sun
      - entity: sun.sun
