Row of buttons without margin

Hi,

I have 4 buttons to choose my home mode. It can only be one mode at a time, so when clicking a button, the one that was selected is not anymore, like a radio button.
The problem is that I want them to be without margin, to be stuck to each other, like this:

I managed to do this simply by putting my buttons in a custom:vertical-stack-in-card, like this:

type: custom:vertical-stack-in-card
cards:
  - type: horizontal-stack
    cards:
      - type: custom:button-card
        entity: input_select.house_mode
        name: Presence

          action: call-service
          service: input_select.select_option
          service_data:
            entity_id: input_select.house_mode
            option: Presence
        card_mod:
          style: |
            ha-card {
              {% set mode = states['input_select.house_mode'].state %}
              background-color: {{ 'var(--green-color)' if mode == 'Presence' else 'var(--card-background-color)' }} !important;
              color: {{ '#FFFFFF' if mode == 'Presence' else 'var(--secondary-text-color)' }};
              border-right: 1px solid var(--ha-card-border-color) !important;
            }
        styles:
          icon:
            - color: >-
                [[[ return states["input_select.house_mode"].state ===

            ha-card {

            }

              color: {{ '#FFFFFF' if mode == 'Night' else 'var(--secondary-text-color)' }};
              border-right: 1px solid var(--ha-card-border-color) !important;
            }
        styles:

                [[[ return states["input_select.house_mode"].state === "Night" ?
                "#FFFFFF" : "var(--secondary-text-color)"; ]]]
      - type: custom:button-card
        entity: input_select.house_mode
        name: Holiday
        icon: mdi:beach
        tap_action:

          service: input_select.select_option
          service_data:
            entity_id: input_select.house_mode
            option: Holiday
        card_mod:
          style: |
            ha-card {
              {% set mode = states['input_select.house_mode'].state %}
              background-color: {{ 'var(--orange-color)' if mode == 'Holiday' else 'var(--card-background-color)' }} !important;
              color: {{ '#FFFFFF' if mode == 'Holiday' else 'var(--secondary-text-color)' }};
            }
        styles:
          icon:
            - color: >-
                [[[ return states["input_select.house_mode"].state ===
                "Holiday" ? "#FFFFFF" : "var(--secondary-text-color)"; ]]]

But since a recent update, it no longer works, so I get this:

I tested a lot of card_mod things but nothing that really helps…

Do you know how can I achieve this ? I’m open to all kinds of suggestions, whether in terms of style, the use of an HACS plugin, etc.
