🔹 Card-mod - Add css styles to any lovelace card

How to set a custom width? I can’t find an example you did this already.

What I have:
grafik

  - type: custom:stack-in-card
    title: ''
    mode: vertical
    keep:
      background: true
      box_shadow: true
      margin: true
      outer_padding: true
      border_radius: true
    cards:
      - type: entities
        entities:
          - entity: climate.thermostat
            secondary_info: last-changed
        card_mod:
          style:
            .: |
              ha-card {
                margin-left: -15px;
                margin-right: -15px;
                margin-top: -15px;
                margin-bottom: -13px;
                box-shadow: none;
              }
      - type: horizontal-stack
        cards:
          - type: custom:slider-entity-row
            entity: climate.thermostat
            name: ''
            hide_when_off: false
            full_row: true
            min: 7
            max: 32
            step: 1
            attribute: temperature
            toggle: false
            show_state: true
            state_color: true
            secondary_info: last-changed
            state_header: ''
            column: false
          - type: custom:climate-mode-entity-row
            entity: climate.thermostat
            name: ' '
            icon: none
            secondary_info: none
            modes:
              - hvac_mode: auto
                icon: mdi:calendar-sync
                color: green
              - hvac_mode: heat
              - hvac_mode: 'off'
    card_mod:
      style:
        .: |
          ha-card {
            margin-left: -10px;
            margin-right: -10px;
            margin-top: 0px;
            margin-bottom: 15px;
            #box-shadow: none;
          }

What I want:
grafik

Using about 75 % for the left row, 25 % for the right one. Currently it is equally (50 %).
