I am using 'custom:button-card' in home assistant. I want this animation from this site on a button:

To replicate that animation from the CodePen link on a custom:button-card in Home Assistant, you can use the extra_styles property to add the necessary CSS. Here’s an example of how you might set it up:

<syntaxhighlight lang="yaml">type: custom:button-card
entity: fan.cabby_cabby_fan
name: Cabby Fan
styles:
card:
* border-radius: 12px
* padding: 16px
* background-color: #3498db
* color: white
* transition: background-color 0.3s ease
extra_styles: |
.button-card {
position: relative;
overflow: hidden;
}

.button-card:before {
content: "";
position: absolute;
top: 50%;
left: 50%;
width: 300%;
height: 300%;
background: rgba(255, 255, 255, 0.3);
border-radius: 50%;
transition: all 0.6s ease;
transform: translate(-50%, -50%) scale(0);
z-index: 0;
}

.button-card:active:before {
transform: translate(-50%, -50%) scale(1);
}

</syntaxhighlight>

This will create a circular ripple effect when you click the button. Adjust the background and other properties as needed to fit your design. Let me know if you need further customization!

=== User: This didn't work ===

=== Assistant: Let's adjust that. ===
Let's adjust that. Make sure you're using the correct CSS properties for the custom:button-card. Here's a revised version that should work better:

<syntaxhighlight lang="yaml">type: custom:button-card
entity: fan.cabby_cabby_fan
name: Cabby Fan
styles:
card:
* border-radius: 12px
* padding: 16px
* background-color: #3498db
* color: white
* position: relative
* overflow: hidden
* transition: background-color 0.3s ease
extra_styles: |
.button-card:before {
content: "";
position: absolute;
top: 50%;
left: 50%;
width: 300%;
height: 300%;
background: rgba(255, 255, 255, 0.3);
border-radius: 50%;
transition: transform 0.6s ease;
transform: translate(-50%, -50%) scale(0);
z-index: 0;
}

.button-card:active:before {
transform: translate(-50%, -50%) scale(1);
}

.button-card:hover {
background-color: #2980b9; /'' Optional: Change background color on hover ''/
}

</syntaxhighlight>

Make sure to clear your browser cache or refresh Home Assistant to see the changes. If it still doesn't work, please check the developer console for any errors that might help diagnose the issue. Let me know how it goes!

I'm not sure if the content under 'extra_styles' would work

=== Assistant: You're right to double-check that. ===
You're right to double-check that. The extra_styles in custom:button-card works a bit differently than standard CSS. Here’s an updated example that utilizes the correct approach:

<syntaxhighlight lang="yaml">type: custom:button-card
entity: fan.cabby_cabby_fan
name: Cabby Fan
styles:
card:
* border-radius: 12px
* padding: 16px
* background-color: #3498db
* color: white
* position: relative
* overflow: hidden
* transition: background-color 0.3s ease
name:
* z-index: 1 # Ensure text is on top
extra_styles: |
.button-card {
position: relative;
overflow: hidden;
}

.button-card::before {
content: "";
position: absolute;
top: 50%;
left: 50%;
width: 300%;
height: 300%;
background: rgba(255, 255, 255, 0.3);
border-radius: 50%;
transition: transform 0.6s ease;
transform: translate(-50%, -50%) scale(0);
z-index: 0;
}

.button-card:active::before {
transform: translate(-50%, -50%) scale(1);
}

.button-card:hover {
background-color: #2980b9; /'' Optional: Change background color on hover ''/
}

</syntaxhighlight>

This code uses ::before for the ripple effect and ensures that it stays behind the text. If it doesn't work, check that your Home Assistant setup allows custom styles and that there are no conflicting styles. Let me know if you run into any issues!

border-radius: 25px;
}
100% {
border: solid var(--border-width) transparent;
box-shadow: 0 0 0 0 rgba(255, 255, 255, 0);
border-radius: 25px;
}
}

=== Assistant: Thanks for sharing that example! ===
Thanks for sharing that example! Based on your working animation, here’s how to create a similar ripple effect animation like the one from the CodePen you referenced, integrated into the custom:button-card format you've provided:

<syntaxhighlight lang="yaml">type: custom:button-card
entity: fan.cabby_cabby_fan
name: Fan
icon: mdi:fan
aspect_ratio: 1/1
show_state: true
styles:
card:
* border-radius: 20px
* position: relative
* overflow: hidden
* box-shadow: 0 4px 20px rgba(0, 0, 0, 0.5)
extra_styles: |
:host {
--ripple-color: rgba(255, 255, 255, 0.5);
}

.button-card:active::after {
content: "";
position: absolute;
top: 50%;
left: 50%;
width: 300%;
height: 300%;
background: var(--ripple-color);
border-radius: 50%;
transform: translate(-50%, -50%) scale(0);
animation: ripple 0.6s linear forwards;
z-index: 0;
}

@keyframes ripple {
to {
transform: translate(-50%, -50%) scale(1);
opacity: 0;
}
}

</syntaxhighlight>

===== - Ripple Effect: The ripple effect is created using a pseudo-element (::after) that scales from the center of the button. =====
* Animation: The @keyframes ripple animation expands the circle and fades it out.
* Styling: You can customize the --ripple-color to match your desired aesthetic.

This setup should give you a nice ripple effect on click. Let me know if you need any further adjustments!

=== User: Here is a SCSS example of an animation. ===
Here is a SCSS example of an animation. How do I use this in a 'custom:button-card':

body {
display: flex;
justify-content: center;
align-items: center;
height: 100vh;
background: #000;
}

'', ''::before, *::after {
box-sizing: border-box;
}

@keyframes rotate {
100% {
transform: rotate(1turn);
}
}

.conic {
position: relative;
z-index: 0;
width: 400px;
height: 300px;
margin: 20px;
border-radius: 10px;
overflow: hidden;
padding: 2rem;

&::before {
content: '';
position: absolute;
z-index: -2;
left: -50%;
top: -50%;
width: 200%;
height: 200%;
background-color: #1a232a;
background-repeat: no-repeat;
background-position: 0 0;
background-image: conic-gradient(transparent, rgba(168, 239, 255, 1), transparent 30%);
animation: rotate 4s linear infinite;
}

&::after {
content: '';
position: absolute;
z-index: -1;
left: 6px;
top: 6px;
width: calc(100% - 12px);
height: calc(100% - 12px);
background: #000;
border-radius: 5px;
}
}

.conic-demo::after {
animation: opacityChange 5s infinite linear;
}

@keyframes opacityChange {
50% {
opacity:.5;
}
100% {
opacity: 1;
}
}

To implement the SCSS animation you provided into a custom:button-card, you can convert the SCSS structure to standard CSS and then use the extra_styles property. Here's how you can achieve that:

<syntaxhighlight lang="yaml">type: custom:button-card
entity: fan.cabby_cabby_fan
name: Fan
icon: mdi:fan
aspect_ratio: 1/1
show_state: true
styles:
card:
* border-radius: 10px
* position: relative
* overflow: hidden
* padding: 2rem
* z-index: 0
extra_styles: |
:host {
background: #000;
display: flex;
justify-content: center;
align-items: center;
height: 100%;
}

.button-card::before {
content: '';
position: absolute;
z-index: -2;
left: -50%;
top: -50%;
width: 200%;
height: 200%;
background-color: #1a232a;
background-repeat: no-repeat;
background-position: 0 0;
background-image: conic-gradient(transparent, rgba(168, 239, 255, 1), transparent 30%);
animation: rotate 4s linear infinite;
}

.button-card::after {
content: '';
position: absolute;
z-index: -1;
left: 6px;
top: 6px;
width: calc(100% - 12px);
height: calc(100% - 12px);
background: #000;
border-radius: 5px;
}

@keyframes rotate {
100% {
transform: rotate(1turn);
}
}

@keyframes opacityChange {
50% {
opacity: 0.5;
}
100% {
opacity: 1;
}
}

.button-card.conic-demo::after {
animation: opacityChange 5s infinite linear;
}

</syntaxhighlight>

===== Key Adjustments: =====
# Card Styles: Set up basic card properties and the layout.
# Before/After Pseudo-elements: Use ::before and ::after to create the rotating background and inner shadow effect.
# Keyframes: The animations are defined directly in the extra_styles so that they apply correctly.
# Z-index Management: The z-index values are set to ensure layering works as intended.

Make sure to adjust the card's size or positioning as needed for your interface. Let me know if you need further tweaks!

To ensure the rotating animation works properly in the custom:button-card, we might need to clarify the usage of CSS animations and check a few details. Here's an updated approach to make sure the animation is correctly applied:

<syntaxhighlight lang="yaml">type: custom:button-card
entity: fan.cabby_cabby_fan
name: Fan
icon: mdi:fan
aspect_ratio: 1/1
show_state: true
styles:
card:
* border-radius: 10px
* position: relative
* overflow: hidden
* padding: 2rem
* z-index: 0
extra_styles: |
:host {
background: #000;
display: flex;
justify-content: center;
align-items: center;
height: 100%;
}

.button-card::before {
content: '';
position: absolute;
z-index: -2;
left: -50%;
top: -50%;
width: 200%;
height: 200%;
background-color: #1a232a;
background-repeat: no-repeat;
background-position: 0 0;
background-image: conic-gradient(transparent, rgba(168, 239, 255, 1), transparent 30%);
animation: rotate 4s linear infinite; /'' Ensure this is correct ''/
}

.button-card::after {
content: '';
position: absolute;
z-index: -1;
left: 6px;
top: 6px;
width: calc(100% - 12px);
height: calc(100% - 12px);
background: #000;
border-radius: 5px;
}

@keyframes rotate {
100% {
transform: rotate(1turn);
}
}

@keyframes opacityChange {
50% {
opacity: 0.5;
}
100% {
opacity: 1;
}
}

.button-card.conic-demo::after {
animation: opacityChange 5s infinite linear;
}

</syntaxhighlight>

===== Key Points to Check: =====
# Animation: Ensure that the animation property in ::before is set correctly (animation: rotate 4s linear infinite;).
# Z-index: Confirm that the z-index of the ::before element is negative so it stays behind the button content.
# Browser Support: Make sure you are testing in a browser that supports CSS animations and conic-gradient.
# Container Size: If the button card size is too small, the effect might not be visible. Consider adjusting the aspect_ratio or padding.

If it still doesn’t work, try removing the conic-gradient temporarily to see if the rotation itself is functioning. Let me know how it goes!
