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

anon36468094 · March 5, 2021, 9:19am

Searching for days but can’t find a solution. Is it possible to change the icon on a state?

card:
  type: horizontal-stack
  cards:
    - type: entity
      entity: media_player.samsung_tv_remote
      icon: 'mdi:monitor'
      style: |
        ha-card {
          --state-icon-color: {% if is_state('media_player.samsung_tv_remote', 'on') %} #50A14F {% else %} #5591c2 {% endif %};
          }
      name: TV living```

Cannot check "background" but "text-align" works:

type: vertical-stack
title: >-
  card-mod 2 vs card-mod 3
cards:
  - type: markdown
    content: |-
      text text text text text text
      text text text text text text
    card_mod:
      style: |
        ha-card {
          text-align: center;
        }
  - type: markdown
    content: <h1>Example</h1><h2>Hello</h2><h3>World</h3>
    style: |
      ha-card {
        text-align: center;
      }

That’s 100% a caching issue.
Make sure your browser console says you’re using card-mod 3.
Otherwise, try this: https://github.com/thomasloven/hass-config/wiki/Lovelace-Plugins#clearing-cache

I am using card-mod 3 and I converted all of my style: keys to be underneath the new card_mod: key. Everything works fine EXCEPT when I’m using the Home Assistant iOS app and off-network via Home Assistant Cloud to view my dashboard. Under this condition, all of the new card_mod: styles are not taking affect at all. I can revert one or more of them back to the old method, Save, Reload, and those styles return.

Again, this is only happening on the iOS app via Home Assistant Cloud (nabu case). When I’m on-net it works fine. On my desktop browser, it works both on-net and via Cloud.

Anybody else having this issue?

KTibow · March 6, 2021, 2:44am

It’s caching.

rnot · March 6, 2021, 2:45am

I can revert one or more of them back to the old method, Save, Reload, and those styles return. Edit it back to new method, they break again. Does caching save between versions of the dashboard?

KTibow · March 6, 2021, 2:46am

Caching is caused by your browser. Google “how to clear cache [however you view ha]”.

rnot · March 6, 2021, 2:46am

Okay, reset Front End cache worked. You probably mean its caching the old version of card-mod.

DavidFW1960 · March 6, 2021, 2:47am

Reset the frontend cache in the iOS app. I don’t see any issues with the app and card mod 3 and I reworked all my cards for the new syntax yesterday. They all work fine.

rnot · March 6, 2021, 2:48am

Yep that did it. Didn’t consider caching because it worked when on-network, only broke when I turned off wifi to enable HA Cloud. Wierd. Thanks for the help @KTibow and @DavidFW1960.

DavidFW1960 · March 6, 2021, 2:52am

Honestly the whole caching thing is a bitch on iOS. I can delete all website data in the Chrome app and it will still load the old card until I reset the frontend cache in the app which should not be related anyway.
I also find on my PC chrome I need to go to dev-tools and then right click refresh and select empty cache and hard reload and then do a CTRL+F5 TWICE before everything will work reliably and properly. I thought the point of using HACS and a non-caching endpoint for resources was supposed to prevent this kind of BS…

AdmiralStipe · March 6, 2021, 1:37pm

Although I believe, that this mod only styles cards, I’m still interested, is it possible to use it somehow to style the background of the dashboard… I would like to use this script, can it be done in any way?

KTibow · March 6, 2021, 3:05pm

That script uses JS, and creates additional elements, both of which card-mod cannot do on its own.

AdmiralStipe · March 6, 2021, 3:11pm

Thought so, thx for reply .

not_a_coder · March 7, 2021, 7:35am

I would like to be able to change the font size of everything in the Lovelace dashboard that uses font-size: var(--paper-font-body1_-_font-size); to a font size of 24px. If I have to use card-mod for every single entity I am fine with that but I am unable to get card-mod to override font-size: var(--paper-font-body1_-_font-size);

First I attempted formatting just one of the entities in an entities card. Then I tried formatting the whole entities card. Neither attempt was successful.

Here is one of my attempts

type: entities
entities:
  - entity: sensor.samjin_water_75430b01_temperature
    card_mod:
      style: |
        :host {
          font-size: 24px;
          }  
  - entity: sensor.inovelli_unknown_type_000d_id_0001_temperature
  - entity: switch.smartswitch_on_off

Here is another attempt

type: entities
card_mod:
  style: |
    ha-card {
    font-size: 24px;
    }
entities:
  - entity: sensor.samjin_water_75430b01_temperature
  - entity: sensor.inovelli_unknown_type_000d_id_0001_temperature
  - entity: switch.smartswitch_on_off

Am I formatting the card incorrectly in both attempts? Is there something different I should be doing if I want all of the fonts that use font-size: var(--paper-font-body1_-_font-size); to be set to 24px?

I have multiple Lovelace dashboards and only want one of them to have all fonts that use font-size: var(--paper-font-body1_-_font-size); to have 24px so I don’t want to adjust a theme unless I need to make a new theme and have just this dashboard use the adjusted theme.

edit: I had a test dashboard and the first example started to work at some point. I’m not sure when or why since I haven’t been visiting the page. I have now applied the setting to my Wallmount dashboard. It’s pretty nice.

parautenbach · March 7, 2021, 8:13am

I’m on my phone but have a look or search for overriding the CSS variable in a custom.js file instead. It will set it globally, for all themes.

not_a_coder · March 7, 2021, 8:15am

I would like to edit just one dashboard or just one theme and apply it to just this one dashboard
