Cover Card
Sections are split:
Main Icon Styling
You can style the main icon like this:
Change the icon type/mdi.
card_mod:
style: |
ha-state-icon {
--card-mod-icon: mdi:mushroom;
}
Change the icon color.
card_mod:
style: |
ha-state-icon {
color: orange;
}
Change icon size.
card_mod:
style: |
ha-state-icon {
--icon-symbol-size: 40px;
}
Rotate Icon.
card_mod:
style: |
ha-state-icon {
rotate: 30deg;
}
Offset/Pad Icon.
This one there is a couple different ones you can use, and also some different value types. i would just play around with it until you find what you like.
card_mod:
style: |
ha-state-icon {
padding-right: 30px;
padding-left: 10px;
padding-bottom: -20px;
height: 20px;
width: 50px;
}
Animate the Icon.
If you are using an animation you need to put your keyframes outside of the ha-state-icon, like the below.
card_mod:
style: |
ha-state-icon {
animation: wobbling 0.7s linear infinite alternate;
}
@keyframes wobbling {
0% {transform: rotate(-80deg);}
100% {transform: rotate(40deg);}
}
End Icon Styling Section
Main Icon Background/Shape Styling
You can style the main icon background/shape like this:
Shape Color.
card_mod:
style:
mushroom-shape-icon$: |
.shape {
--shape-color: orange !important;
}
Shape Size.
You should set the icon size to 21px as this is the standard size for mushroom cards. you are then free to change the size of the shape without affecting the icon.
card_mod:
style:
mushroom-shape-icon$: |
.shape {
--icon-symbol-size: 21px;
--icon-size: 100px;
}
Shape Shadow.
Left with shadow, right standard without shadow. !important seems to be required.
card_mod:
style:
mushroom-shape-icon$: |
.shape {
box-shadow: 0px 2px 4px 0px rgba(0,0,0,0.36) !important;
}
Shape “Shape”?
Note that it doesnt seem like you can use negative values here.
card_mod:
style:
mushroom-shape-icon$: |
.shape {
padding-right: 40px;
padding-left: 10px;
padding-bottom: 10px;
}
Shape Outline/Border.
the different border types can be found here.
card_mod:
style:
mushroom-shape-icon$: |
.shape {
border: 2.5px outset green
}
Shape Animation.
If you are using an animation you need to put your keyframes outside of the .shape, like the below.
card_mod:
style:
mushroom-shape-icon$: |
.shape {
--shape-animation: ping 2s infinite;
}
@keyframes ping {
0% {box-shadow: 0 0 0 0 rgba(var(--rgb-red), 0.7);}
70% {box-shadow: 0 0 0 10px transparent;}
100% {box-shadow: 0 0 0 0 transparent;}
}
End Shape/Icon Background Styling Section
Card Styling
The card body itself can be styled like this:
Background Color.
Note that any buttons and sliders also seem to change color according to this color. you can style the buttons seperately which you will see later in the guide.
card_mod:
style: |
ha-card {
background-color: #002f7a;
}
Background outline/border.
Note that setting a border size does seem to change the actual card size slightly. border types can be found here.
card_mod:
style: |
ha-card {
border: 2.5px outset blue
}
Card shadow.
You can use this to both add a shadow and remove one if your theme has a shadow by default like mine does (minimalist).
Add Shadow.
card_mod:
style: |
ha-card {
box-shadow: 0px 2px 4px 0px rgba(0,0,0,0.66);
}
Remove Shadow.
card_mod:
style: |
ha-card {
box-shadow: none;
}
Card size.
This changes the outside size of the card. not any of the interior contents. you have to use !important it seems for height to actually change.
card_mod:
style: |
ha-card {
height: 200px !important;
width: 200px;
}
Card padding.
This adds interior padding to the card and therefore squishes the internals into the dimensions of the card more. the interior items will get smaller. you have to use !important it seems for padding to take effect.
card_mod:
style: |
ha-card {
padding-right: 150px !important;
padding-left: 150px !important;
padding-bottom: 30px !important;
padding-top: 30px !important;
}
Card margins.
Card margin adds blank space to the outside of the card squeezing the entire card (interiror and exterior) into a smaller space, making the whole card smaller.
card_mod:
style: |
ha-card {
margin-top: 30px;
margin-bottom: 30px;
margin-left: 30px;
margin-right: 30px;
}
Card Border/Corner Radius.
Changes the radius of the corners. this is set to 0. so sharp corners.
card_mod:
style: |
ha-card {
border-radius: 0px;
}
Card Shape Animation
card_mod:
style: |
ha-card {
border-radius: 20px !important;
animation: ping 2s infinite;
}
@keyframes ping {
0% {box-shadow: 0 0 0 0 rgba(var(--rgb-red), 0.7);}
70% {box-shadow: 0 0 0 10px transparent;}
100% {box-shadow: 0 0 0 0 transparent;}
}

Text Styling
Primary (or first line) text can be styled like this:
Change Font.
maybe dont use Wingdings 
card_mod:
style: |
ha-card {
font-family: "Wingdings 2";
}
Change Font Style.
Font styles can be found here.
card_mod:
style: |
ha-card {
font-style: italic;
}
Change Font Variant.
Font variants can be found here.
card_mod:
style: |
ha-card {
font-variant: small-caps;
}
Change Font Size.
I have not found a way to change font size for text across the board. you have to do them individually it seems.
card_mod:
style:
mushroom-state-info$: |
.container {
--card-secondary-font-size: 20px;
--card-primary-font-size: 20px;
}
Change Font Color.
I have not found a way to change color for text accross the board. you have to do them individually it seems.
card_mod:
style:
mushroom-state-info$: |
.container {
--card-primary-color: blue;
--card-secondary-color: orange;
}
Change Alligment
Different allignment options can be found here.
card_mod:
style:
mushroom-state-info$: |
.container {
align-items: end;
}
Change Rows.
Gap will need to be adjusted depending on your primary text length. you can find the different types of flex direction here. yaml courtesy of @zanixmechanix
card_mod:
style:
mushroom-state-info$: |
.container {
flex-direction: row !important;
align-items: baseline;
gap: 10px;
}

End of Badge Icon Shape Styling Section
Slider Styling
If you have sliders they can be controlled like this:
Change color.
card_mod:
style:
mushroom-cover-position-control$: |
mushroom-slider {
--main-color: teal !important;
--bg-color: #d1eced !important;
}
mushroom-cover-tilt-position-control$: |
mushroom-slider {
--main-color: teal !important;
--bg-color: #d1eced !important;
}
Change Size
There isnt enough space to make the slider any bigger so if that is your aim i would recommend making the box that they live in bigger as well. like the below. of course this doesnt apply if you are making the buttons smaller. !important is required.
card_mod:
style:
mushroom-cover-position-control$:
mushroom-slider$: |
.slider {
width: 200px !important;
height: 200px !important;
}
mushroom-cover-tilt-position-control$:
mushroom-slider$: |
.slider {
width: 200px !important;
height: 200px !important;
}
.: |
mushroom-cover-position-control {
height: 200px;
}
mushroom-cover-tilt-position-control {
height: 200px;
}
Rotate slider
I would not recommend using this. the control doesnt follow the direction of the slider. it is just a bad idea.
card_mod:
style:
mushroom-cover-position-control$:
mushroom-slider$: |
.slider {
rotate: 90deg;
}
mushroom-cover-tilt-position-control$:
mushroom-slider$: |
.slider {
rotate: 90deg;
}
.: |
mushroom-cover-position-control {
height: 200px;
}
mushroom-cover-tilt-position-control {
height: 200px;
}
Offset/Pad Slider
You have to use margin instead of padding. padding only seems to make the slider itself bigger.
card_mod:
style:
mushroom-cover-position-control$:
mushroom-slider$: |
.slider {
margin-right: 100px;
margin-top: 30px !important;
}
mushroom-cover-tilt-position-control$:
mushroom-slider$: |
.slider {
margin-right: 100px;
margin-top: 30px !important;
}
.: |
mushroom-cover-position-control {
height: 74px;
}
mushroom-cover-tilt-position-control {
height: 74px;
}
Animate Slider Shape.
i would recommend adding some padding so that the animation has the space to show. you need to put your keyframes outside of the .slider, like the below.
card_mod:
style:
mushroom-cover-position-control$:
mushroom-slider$: |
.slider {
animation: ping 2s infinite;
}
@keyframes ping {
0% {box-shadow: 0 0 0 0 rgba(var(--rgb-red), 0.7);}
70% {box-shadow: 0 0 0 10px transparent;}
100% {box-shadow: 0 0 0 0 transparent;}
}
mushroom-cover-tilt-position-control$:
mushroom-slider$: |
.slider {
animation: ping 2s infinite;
}
@keyframes ping {
0% {box-shadow: 0 0 0 0 rgba(var(--rgb-red), 0.7);}
70% {box-shadow: 0 0 0 10px transparent;}
100% {box-shadow: 0 0 0 0 transparent;}
}
.: |
mushroom-cover-position-control {
padding: 10px;
height: 40px;
}
mushroom-cover-tilt-position-control {
padding: 10px;
height: 40px;
}
Slider Border.
Maybe add some padding the the box the slider lives in.
card_mod:
style:
mushroom-cover-position-control$:
mushroom-slider$: |
.slider {
border: dashed blue !important;
}
mushroom-cover-tilt-position-control$:
mushroom-slider$: |
.slider {
border: dashed blue !important;
}
End of Slider Styling Section

If you have control buttons they can be styled like this:
Change the icon type/mdi.
increment the nth-child(1) by +1 for every button that you have in your card. and then style them individually as you see fit. if you have the tilt or position control button it needs to be styled seperately.

.button ::slotted(*) {
animation: wobbling 0.7s linear infinite alternate;
}
@keyframes wobbling {
0% {transform: rotate(-80deg);}
100% {transform: rotate(40deg);}
}

Button Size.

There isnt enough space to make the button any bigger so if that is your aim i would recommend making the boxes that they live in bigger as well. like the below. of course this doesnt apply if you are making the buttons smaller.
card_mod:
style:
mushroom-cover-buttons-control$:

.button {
height: 100px !important;
width: 100px !important;
}
mushroom-button$: |
.button {

}
mushroom-button {
height: 100px !important;
width: 100px !important;
}
Button Location.
increment the nth-child(1) by +1 for every button that you have in your card. and then style them individually as you see fit. if you have the tilt or position control button it needs to be styled seperately. Only margin top and left work, but negative values are allowed so you can move them anywhere you please. you can add extra space like the above by making the boxes that the buttons live in bigger if you need it.
card_mod:
style:
mushroom-cover-buttons-control$:
mushroom-button:nth-child(1)$: |
.button {
margin-top: 20px !important;

mushroom-button:nth-child(1)$: |
.button {
border: dashed blue !important;
}
mushroom-button$: |
.button {
border: dashed blue !important;
}
Button Reverse Order.
You can flip the order of the main buttons, but unfortunately since the tilt/position button is seperate that wont flip with it.
card_mod:
style:
mushroom-cover-buttons-control$: |
:host {
transform: scalex(-1);
}
Animate buttons shape.
i would recommend adding some padding to the boxes that the buttons live in just so that there is space for the animation. you will need to put your keyframes outside of the .button, like the below.
card_mod:
style:
mushroom-cover-buttons-control$:
mushroom-button:nth-child(1)$: |
.button {
animation: ping 2s infinite;
}
@keyframes ping {
0% {box-shadow: 0 0 0 0 rgba(var(--rgb-red), 0.7);}
70% {box-shadow: 0 0 0 10px transparent;}
100% {box-shadow: 0 0 0 0 transparent;}
}
mushroom-button$: |
.button {
animation: ping 2s infinite;
}
@keyframes ping {
0% {box-shadow: 0 0 0 0 rgba(var(--rgb-red), 0.7);}
70% {box-shadow: 0 0 0 10px transparent;}
100% {box-shadow: 0 0 0 0 transparent;}

Wow!
