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

W/o checking other things - this code is wrong in part of syntax.
Check other examples in the thread ā€œaccessing shadowRoot + ha-cardā€.
Also , you cannot use # for comments inside strings.

Slowly making progress. I got the knob to disappear with this:

card_mod:
  style:
    ha-slider:
      $:
        .: |
          .slider-knob-inner {
            opacity: 0%;
          }

And the height of the slider to change with this:

card_mod:
  style: |
    :host {
      --paper-slider-height: 42px;
    }  

Iā€™m having trouble combining the two however.

Iā€™ve now combined the two and extended the slider to the edges of the card.
Next goal is to round the corners on the slider. If I use inspect element to add border-radius: 12px to the sliderBar property it only works when I disable the padding property.

With padding 15px top and bottom and border-radius 12px:
chrome_4iSIBUSTmk
With padding 0px and border-radius 12px:
chrome_QTVia8Z1lx

Any tips on getting around this problem?

Another issue is that once I set the slider to 0% the first part disappears:

Slider at 1%:
chrome_KV8q6osg8X
Slider at 0%:
chrome_yZ47DvIb0w

This is the current code:

    card_mod:
      style:
        .: |
          :host {
            --paper-slider-height: 42px
          }
        ha-slider:
          $:
            .: |
              .slider-knob-inner {
                opacity: 0%;
              }
              div#sliderContainer {
                  margin-left: 0;
                  margin-right: 0;                                                
              }
            paper-progress:
              $: |
                #progressContainer {
                  background: red;
                }

Solved pretty much everything, the only thing left is to adjust the padding so that it matches mushroom-cards perfectly. To do so I have to add ā€œpadding: ā€˜13px 12pxā€™ā€ to the states div inside ha-card, but Iā€™m having troubles doing so. Iā€™ve found some old posts but I guess the syntax is different nowadays since I couldnā€™t get their snippets to work.

EDIT:

Got it working, I had to apply the padding styling to the whole card and not the entity. Hereā€™s the final code and result, top is mushroom-card light card slider set to adjust brightness, bottom is two slider-entity-row sliders, one to control the light warm_white channel and one to control the cold_white channel:

chrome_W86Ego5171

Everything matches, altho the scrubbing on the mushroom card is much smoother, I assume because slider-entity-row only has 255 ā€œstepsā€. Here you can find the code for this card:

Nice mod.
Check this version, it has a ā€œstandardā€ height and a bit more ā€œtraditionalā€ syntax.
BTW, the style may be applied to ā€œslider-entity-rowā€ & conventional slider.

type: entities
entities:
  - sun.sun
  - sun.sun
  - entity: input_number.test_level_1
    card_mod: &ref_0

        ha-slider $: |
          div#sliderKnob {
            height: 32px;
          }
          .slider-knob-inner {
            display: none;
          }
          div#sliderContainer {
            margin: 0px;                                                
          }

Note that this code:
--paper-slider-active-color: {{ '#ffcd97' if config.attribute == 'warm_white' else '#99acff' }};
does not update a color real-time - only after releasing a mouse input.


A bit modified version with a border:

Code
    card_mod:
      style:
        ha-slider $: |
          div#sliderKnob {
            height: 30px;
          }
          .slider-knob-inner {
            display: none;
          }
          div#sliderContainer {
            margin: 0px;                                                
          }
          .bar-container {
            left: 0px !important;
          }
          paper-progress {
            padding: 0px !important;
            border-radius: 12px;
            --paper-progress-height: 30px !important;
            width: unset !important;
            border: 1px solid darkgreen;
          }
        .: |
          :host {
            --paper-slider-active-color: lightgreen;
            --paper-slider-container-color: darkgreen;
          }

A variant with a knob:
12

Code
          div#sliderKnob {
            height: 30px;
            width: 8px;
            margin-left: -4px;
            background: var(--card-background-color);
            border: 1px solid var(--secondary-text-color);
          }

How to style map markers in Map card:

Initially the styling was discussed here, here, some other posts later.
Unfortunately, styles were not stable.

Solution was proposed on GitHub.
Author - @kulmegil.
Works in Map card & on a Map page.

image

Place this js code into ā€œwwwā€ folder (or better create a special folder) and then add as a frontend module:

customElements.whenDefined('ha-entity-marker').then(() => {
    const EntityMarker = customElements.get('ha-entity-marker');
    const { html, css } = EntityMarker.prototype;
    
    // defined added style
    const newStyle = css`
    .marker {
      border: none !important;
      background-color: transparent !important;}`;
    
    const newStyles = [].concat(EntityMarker.styles, newStyle);
    Object.defineProperty(EntityMarker, 'styles',        {value: newStyles, configurable: true, enumerable: false});
    Object.defineProperty(EntityMarker, 'elementStyles', {value: newStyles, configurable: true, enumerable: false});
  });

Similarly it is possible to create ā€œsquare avatarsā€ - add this style:

border-radius: 10%;

image


Update 31.01.23:
The styling above provides a ā€œsquare & transparentā€ marker - which is great for entities WITH ā€œentity_pictureā€ defined.
But what if it is NOT defined? Then weā€™ll see smth like this:
ŠøŠ·Š¾Š±Ń€Š°Š¶ŠµŠ½ŠøŠµ
i.e. the marker now is presented as a label only - which is not great.

This updated js-file provides styles ONLY for entities with ā€œentity_pictureā€ defined:
ŠøŠ·Š¾Š±Ń€Š°Š¶ŠµŠ½ŠøŠµ
The js code:

customElements.whenDefined('ha-entity-marker').then(() => {
    const EntityMarker = customElements.get('ha-entity-marker');
    const { html, css } = EntityMarker.prototype;
    
    // defined added style
    const newStyle = css`
    .marker:has(.entity-picture) {
      border: none !important;
      border-radius: 10%;
      background-color: transparent !important;}`;
    
    const newStyles = [].concat(EntityMarker.styles, newStyle);
    // The LitElement class has already been finalized, but hopefully not yet instantiated
    // guess I'll just do it the hard way
    Object.defineProperty(EntityMarker, 'styles',        {value: newStyles, configurable: true, enumerable: false});
    Object.defineProperty(EntityMarker, 'elementStyles', {value: newStyles, configurable: true, enumerable: false});
  });

Note that ā€œ.marker:has(.entity-picture)ā€ part.

Conditional styling for different clients:

Assume you have a Windows desktop, iPhone & iPad.
In some cases we need to specify different styles for different clients.

Here is how to differentiate iOS client & not-iOS client:
place a selector with a style into a condition to specify a style for iOS clients:

        @supports (-webkit-touch-callout: none) {
          selector {
            ...
          }
        }

The example below contains 3 rows:
ā€“ styled for all clients;
ā€“ styled for iOS clients;
ā€“ styled for not iOS clients.

Code
type: entities
entities:
  - entity: sun.sun
    name: everywhere
    card_mod:
      style: |
        :host {color: red}
  - entity: sun.sun
    name: iOS clients
    card_mod:
      style: |
        @supports (-webkit-touch-callout: none) {
          :host {color: red;}
        }
  - entity: sun.sun
    name: not iOS clients
    card_mod:
      style: |
        @supports not (-webkit-touch-callout: none) {
          :host {color: red;}
        }

Screenshots are taken on a Windows desktop.

If a style includes a "shadowRoot" - need to place that conditions in every place.
Consider this style:

type: entities
entities:
  - entity: sun.sun
    name: Colored name & value
    style:
      hui-generic-entity-row $: |
        .info.pointer.text-content {
          color: orange;
        }
        .text-content:not(.info) {
          color: red;
        } 
      .: |
        :host {
          --paper-item-icon-color: cyan;
        }

image

Here is how to render it:

    card_mod:
      style:
        hui-generic-entity-row $: |
          @supports (-webkit-touch-callout: none) {
            .info.pointer.text-content {
              color: orange;
            }
            .text-content:not(.info) {
              color: red;
            }
          }        
        .: |
          @supports (-webkit-touch-callout: none) {
            :host {
              --paper-item-icon-color: cyan;
            }
          }

A bit cumbersome; unfortunately, we cannot place the whole style into one condition:

    card_mod:
      style: |
        @supports not (-webkit-touch-callout: none) {
          hui-generic-entity-row $: |
            .info.pointer.text-content {
              color: orange;
            }
            .text-content:not(.info){
              color: red;
            }
          .: |
            :host {
              --paper-item-icon-color: cyan;
            }
        }

Next point is - how to differentiate iPhone & iPad?
A desktop with 4K display & smaller panel 1920x1080?

Use "@media" conditions for different viewports & screen orientations.

Assume that besides Windows clients we have 3 iOS devices - iPad Air 2, iPhone 5s, iPhone 6 (please do not tell me that they are ancient - I do know it; you wanna fix it - buy me a coffee).
And we need 5 styles for these devices - and these styles must work for these devices only.
Means - we need to define rules for each device.

This code works on a Windows client with 1920x1080 display (fullscreen or less):

    card_mod:
      style: |
        @supports not (-webkit-touch-callout: none) {
          @media (max-width: 1920px) {
            :host { color: red; }
          }
        }

The code for a Windows client with 4K display (fullscreen or less):

    card_mod:
      style: |
        @supports not (-webkit-touch-callout: none) {
          @media (min-width: 1921px) and (max-width: 3840px) {
            :host { color: red; }
          }
        }

This code for iPad Air 2 (1536x2048) for different orientations:

    card_mod:
      style: |
        @supports (-webkit-touch-callout: none) {
          @media (orientation: portrait) and (min-width: 768px) {
            :host { color: red; }
          }
        }
    card_mod:
      style: |
        @supports (-webkit-touch-callout: none) {
          @media (orientation: landscape) and (min-width: 1024px) {
            :host { color: red; }
          }
        }

This code for iPhone 5S (640x1136) for different orientations:

    card_mod:
      style: |
        @supports (-webkit-touch-callout: none) {
          @media (orientation: portrait) and (max-width: 320px) {
            :host { color: red; }
          }
        }
    card_mod:
      style: |
        @supports (-webkit-touch-callout: none) {
          @media (orientation: landscape) and (max-width: 568px) {
            :host { color: red; }
          }
        }

This code for iPhone 6 (750x1334) for different orientations:

    card_mod:
      style: |
        @supports (-webkit-touch-callout: none) {
          @media (orientation: portrait) and (min-width: 321px) and (max-width: 375px) {
            :host { color: red; }
          }
        }
    card_mod:
      style: |
        @supports (-webkit-touch-callout: none) {
          @media (orientation: landscape) and (min-width: 569px) and (max-width: 667px) {
            :host { color: red; }
          }
        }

Values for these "min-width" & "max-width" for iOS devices are set dependingly on ā€œviewport sizesā€ which may be found here.
Have no idea how these ā€œviewport sizesā€ are defined; why for iPad it is ā€œ768x1024ā€ for ā€œ1536x2048ā€ resolution and for iPhone it is ā€œ320x568ā€ for ā€œ640x1136ā€ (twice less) - is a riddle for me.
Some info may be googled (for example, here).

Another issue is ā€œscaling in iOS Companion Appā€. My observations tell me that for a correct handling that "@media" conditions the scaling must be ā€œ100%ā€.
I myself usually use ā€œ50%ā€ in Companion App for iPad; as for iPhone - do not use it, the App is too slow / too buggy (much more buggy than the App for iPad). So, with ā€œ50%ā€ I observed that conditions not workingā€¦

I am using a combination of horizontal and vertical stack cards to give me the following:
image
I would like the borders between these elements to be smaller so they look connected, currently the ā€œSelect media deviceā€ looks like another separate element in my dashboard. Is there a way of doing this (I know css fairly well but canā€™t target the margin elements I need). Hereā€™s my yaml for this:

Try with ā€œstack in cardā€ (replaces vertical, horizontal card), itā€™s available in HACS. With it i made similar without any borders.

Iā€™m currently building out my dashboard and when using ā€˜card-modā€™ it does an annoying refresh / flash on the initial load of each tab.

Anyone know how I can get rid of this?

Any tips to put the entity icon inside the slider? I remember reading a post of yours showing how to stack entities on top of each other, I was thinking that was one of the options with the other being to disable full_row on the slider-entity-row and extend the slider all the way to the left.

Unclear, what do you want? Post an MS Paint picture.

Hi, Iā€™m building a floorplan with ha-floorplan and have completed the floorplan element but now want to overlay it with some entities, e.g. temperature gauge or auto-entities. Iā€™ve been searching how to do this and trying different things with card-mod for a few days but Iā€™ve come to a brick wall each time. Iā€™m simply confused by the css and where it needs to go.

Rather than paste my many failed attempts of code, can someone please point me to a very basic example of one card overlaying another, that I can try to understand and then build on please?

All the examples Iā€™ve found so far are too specific for other needs.

Thanks, Matt

Iā€™m trying to make the outer border of a badge larger. Iā€™ve managed to pin down in the inspector where the value is defined within the CSS, however I havenā€™t been able to figure out how to implement it using card mod.

Hopefully the picture is clear enough and I havenā€™t cropped it too poorly. This is what Iā€™m trying to achieve.

My best guess is that Iā€™m somehow not defining the containers correctly. The current code (that isnā€™t working):

      - type: custom:badge-card
        badges:
          - entity: sensor.eetstatus_0
            name: ''
            card_mod:
              style: |
                :host {
                  --label-badge-background-color: rgba(0, 0, 0, 0.85);
                  {% set sens = 'sensor.eetstatus_0' %}
                  {% set eetst = state_attr(sens,'eetlijst_entry') %} 
                  {% if eetst == None %} 
                  --ha-label-badge-label-color: black; --label-badge-red: #f7f5f5;
                  {% else %} 
                   {% if eetst < 0 %} --label-badge-red: #377330; {% elif eetst > 0 %} --label-badge-red: #bd1313; {% elif eetst == 0 %} --label-badge-red: slategrey; {% endif %}
                  {% endif %}
                   --ha-label-badge-size: 75px; }
                ha-state-label-badge:
                  $:
                    ha-label-badge:
                      $:
                        .badge-container
                            .label-badge {
                            border: 0em solid;
                            }

icon inside slider

Without checking the dom, etc., at least this structure and | is missing.

            card_mod:
              style:
                .: |
                  :host {
                    ... }
                ha-state-label-badge:
                  $:
                    ha-label-badge:
                      $: |

After playing around with this further, it appears to be prioritising the initial CSS/Styles first then overlaying the updated card-mod styling which cases the weird flash behaviour.

In my config.yaml file I also put the following to see if it would prioritise the load but it has not worked.

frontend:
  extra_module_url:
    - /hacsfiles/lovelace-card-mod/card-mod.js

Anyone know what I can do to help fix this? Seems I am driving myself mad. I have added an issue here also.
