Hi friends, nice evening to everyone.
I’m using the latest Home Assistant OS and 2025.8 core.
In order to control my ceiling fan’s variable speeds, I created a Horizontal stack on my dashboard.
Is there a way I can configure the Horizontal Stack to highlight the last pressed speed button with a different color, so that I can visibly see which speed is currently running?
Hope someone can help 
I have the following style code setup on my dashboard but I use it with the grid card in horizontal cards withbutton_card_templates and the Custom Button Card. I use the template so I only have to right it once and then just reference the template for each row.
I change the button background (the color of the light) and then the font color and weight when active or inactive. (If you post your code I could probably help more.)
And this YT channel has a part 1-3 that should also help you.
For low I use the following style code.
styles:
card:
- background-color: |
[[[
if ((entity.state == 'on') && (entity.attributes.brightness > 0 ) && (entity.attributes.brightness <= 85 ))
return 'rgba(' + entity.attributes.rgb_color + ', 0.1)';
else return '';
]]]
name:
- font-weight: |
[[[
if ((entity.state == 'on') && (entity.attributes.brightness > 0 ) && (entity.attributes.brightness <= 85 ))
return 500;
else return '';
]]]
- color: |
[[[
if ((entity.state == 'on') && (entity.attributes.brightness > 0 ) && (entity.attributes.brightness <= 85 ))
return 'rgb(255, 255, 255)';
else return '';
]]]
For medium.
styles:
card:
- background-color: |
[[[
if ((entity.state == 'on') && (entity.attributes.brightness > 85 ) && (entity.attributes.brightness <= 170 ))
return 'rgba(' + entity.attributes.rgb_color + ', 0.2)';
else return '';
]]]
name:
- font-weight: |
[[[
if ((entity.state == 'on') && (entity.attributes.brightness > 85 ) && (entity.attributes.brightness <= 170 ))
return 500;
else return '';
]]]
- color: |
[[[
if ((entity.state == 'on') && (entity.attributes.brightness > 85 ) && (entity.attributes.brightness <= 170 ))
return 'rgb(255,255,255)';
else return '';
]]]
For high.
styles:
card:
- background-color: |
[[[
if ((entity.state == 'on') && (entity.attributes.brightness > 170 ))
return 'rgba(' + entity.attributes.rgb_color + ', 0.3)';
else return '';
]]]
name:
- font-weight: |
[[[
if ((entity.state == 'on') && (entity.attributes.brightness > 170 ))
return 500;
else return '';
]]]
- color: |
[[[
if ((entity.state == 'on') && (entity.attributes.brightness > 170 ))
return 'rgb(255,255,255)';
else return '';
]]]
Here’s mine…
OK, but he isn’t using the custom:button-card HACs integration?
I know. I’m just showing him how I did it. He’d still have to use something other than the stock lovelace button card to do it… right?
Thank you for the example, @almighty59 
I will try to learn from it and implement it for my case
No, you can mod the stock cards he is using. An simple example with stock cards and card_mod.
type: horizontal-stack
cards:
- show_name: false
show_icon: true
type: button
entity: script.fan_speed_1
icon: mdi:fan-speed-1
tap_action:
action: toggle
card_mod:
style: |
ha-card {
--state-icon-color: {{ 'snow' if is_state('sensor.fan_speed', '16') else 'grey' }};
background: {{ 'blue' if is_state('sensor.fan_speed', '16') else 'black' }}
}
- show_name: false
show_icon: true
type: button
entity: script.fan_speed_2
icon: mdi:fan-speed-2
tap_action:
action: toggle
card_mod:
style: |
ha-card {
--state-icon-color: {{ 'snow' if is_state('sensor.fan_speed', '33') else 'grey' }};
background: {{ 'blue' if is_state('sensor.fan_speed', '33') else 'black' }}
}
- show_name: false
show_icon: true
type: button
entity: script.fan_speed_3
icon: mdi:fan-speed-3
tap_action:
action: toggle
card_mod:
style: |
ha-card {
--state-icon-color: {{ 'snow' if is_state('sensor.fan_speed', '50') else 'grey' }};
background: {{ 'blue' if is_state('sensor.fan_speed', '50') else 'black' }}
}
- show_name: false
show_icon: true
type: button
entity: script.fan_summer
icon: mdi:horizontal-rotate-counterclockwise
card_mod:
style: |
ha-card {
--state-icon-color: {{ 'blue' if is_state('sensor.fan_direction', 'forward') else 'orange' }};
background: black;
}
Thank you very much, @LiQuid_cOOled
I really appreciate your suggestion.
