Well this post says itâs not possible:
in my opinion this has nothing to do with card_mod but is more of a general CSS topic.

Analogy: By definition of how an iframe works: Itâs like trying to style a page open in another tab in your browser.

Thank you, that makes sense. Itâs confusing because if you use the element inspector in a browser, you can see all the HTML of the iframe nested inside the dashboard.
I guess the only solution would be a proxy server that could inject the new CSS into the page and serve the result up to the frame.
Yes, but it loads independently. The content may not be there when the card-mod changes are injected, but in the case of iframes itâs more about security and cross-origin requests.
Iâm getting lost navigating the DOM.
Trying to modify this Thermostat card:
When I do this, it selects the hui-card-features element:
card_mod:
style: |
hui-card-features {
background-color: red;
}
And when I do this, It selects the first div.container, on 7th line of that screenshot, which is the top half of the card:
card_mod:
style: |
.container {
background-color: red;
}
How do I get it to select the div.container the is inside the hui-card-features element?
Based on Ildarâs example for changing the icons, I thought it was this:
card_mod:
style: |
hui-card-features $: |
.container {
background-color: red;
}
but that doesnât seem to do it.
â
What Iâm trying to do is override the flex-direction: column, changing it to row, that the .container gets from some other style sheet elsewhere so the feature buttons are side-by-side instead of stacked on top of each other.
From this:
To this:
How do I add a font size line into this YAML that already has some style lines? I cant figure it out and chatgpt cant either lol

}
@keyframes ping {
0% { box-shadow: 0 0 0 0 rgba(var(--rgb-red), 0.7); }
100% { box-shadow: 0 0 5px 15px transparent; }
}
@keyframes blink {
100% {opacity: 0;}
}
Donât think, that you found this in the examples. 
But you are on the right track., Remove the fist | after style.
Thank you. That helped.
I can barely even spell CSS, so I get lost trying to understand when and where to use |, |-, >, >-, :, or $: in these.
That got the style injected into the right element, but it still wasnât overriding it until I added a !important. The final block ended up being:
card_mod:
style:
hui-card-features:
$: |
.container {
flex-direction: row !important;
flex-wrap: wrap;
justify-content: center !important;
}
Now the card more closely matches the more info dialog.

Iâm trying to squeeze more text into an entities card. I have this code (within horizontal stack, which explains the indentation):
- type: entities
card_mod:
style: |
hui-generic-entity-row:
$: |
height: 5px;
margin-top: 0px !important;
margin-bottom: 0px !important;
}
entities:
- entity: sensor.jrmc_artist
- entity: sensor.jrmc_lat
- entity: sensor.jrmc_avspillingsstatus
- entity: sensor.jrmc_posisjon
- type: markdown
But it doesnât seem to obey this at all. The result is nowhere near what I want:
I would like to have them as close as possible, so I can get a third line in the same space. Can somebody please help me out?

hmm, suddenly I notice my tile icon is no longer animating. it somehow is bugged by the larger features mod at the top of this mod, because, if I comment that, the animation on the ha-state-icon element after the .: | does work properly, indicating the mod itself is correctly aimed at the right element.
Could anyone please have a look?

Iâm really at a loss here trying to navigate down a few levels to animate an icon contained within a html container. If I define an animation that is already available in HA it is an easy feat. I just add it to the style section of the icon.
`<span style="font-size: 1rem"><ha-icon icon="ios:cloud-rain" style="width: 1.5rem; height: 1.5rem;"></ha-icon> ${states['sensor.home_precipitation'].state} mm/h</span>`
However, I want to customize the animation with some key frames but I donât know how I can access the icon through card mod.
The structure looks like this (starting from the button itself:
The Layout of the button card is pretty simple (with all fields just returning html blocks):
styles:
grid:
- grid-template-areas: |
"cond temp"
"cond feel"
"cond ."
"prec hum"
"wind UV"
- grid-template-columns: 1fr 1fr
- grid-template-rows: max-content max-content 1fr max-content max-content
Can anyone help me figure out how I can address the icon in the highlighted section of the above picture with card mod.
Thanks!
You first need to navigate to a parent element starting from your ha-card element and then use normal css to style your element.
Read up on DOM navigation with card_mod here.
In your case itâs pretty simple as you donât need to go through the shadow dom.
card_mod:
style: |
#container {
grid-template-areas:
"cond temp"
"cond feel"
"cond ."
"prec hum"
"wind UV";
grid-template-columns: 1fr 1fr;
grid-template-rows: max-content max-content 1fr max-content max-content;
}
#hi ha-icon {
your styles
}
Just make sure ha-icon is really what youâre trying to style. You can test that easily by first applying the styles through your browserâs dev tools to see what you need to target with card_mod

That worked beautifully! Very much appreciated.
Sometimes you can also use âextra_stylesâ to inject your animation (e.g. custom:button-card and custom:paper-buttons-row allow that).
I may be blind, but I donât see itâŚ

Card-mod change color of button PRESS.
I am trying to change the color of the PRESS on a button. I was able to change the icon and the name but not the actual PRESS.
Thank you! Finally found it, and it works as I hoped!
