Card_mod: Change secondary text color

I’m trying to color the secondary info text of an Enteties card using Card_mod.

This also works as follows:


card_mod:
  style:
    hui-generic-entity-row $: |
      .info.pointer .secondary ha-relative-time {
          color: red;
      }

However, if I try to combine this with other CSS code, it does not work.


card_mod:
  style: |      
    .entities-row div.entity:nth-child(1) {
      color: green;
    }
    hui-generic-entity-row $: |
      .info.pointer .secondary ha-relative-time {
        color: red;
      }

Is there a way to combine both?

The whole code should be something like this:

type: vertical-stack
cards:
  - type: entities
    entities:
      - entity: sensor.temphum_arbeitszimmer_jo_temperature
        type: custom:multiple-entity-row
        secondary_info: last-changed
        format: precision1
        name: Arbeitszimmer Jo
        styles:
          width: 50px
          text-align: right
        entities:
          - entity: sensor.tc_temphum_arbeitszimmer_jo_absolute_luftfeuchtigkeit
            name: false
            format: precision1
            styles:
              width: 80px
              text-align: right
          - entity: sensor.temphum_arbeitszimmer_jo_humidity
            name: false
            format: precision1
            styles:
              width: 50px
              text-align: right
        card_mod:
          style: >
            {% if
            (float(states('sensor.tc_temphum_arbeitszimmer_jo_absolute_luftfeuchtigkeit'))
            -
            float(states('sensor.tc_temphum_balkon_kue_absolute_luftfeuchtigkeit')))
            > 5 %} .entities-row div.entity:nth-child(1) {
              color: orange;
            } {% endif %} {% if 
            float(states('sensor.temphum_arbeitszimmer_jo_humidity')) > 60 %}
            .entities-row div.entity:nth-child(2) {
              color: orange;
            } {% endif %}
            hui-generic-entity-row $: |
              .info.pointer .secondary ha-relative-time {
                {% set last_updated = states.sensor.temphum_arbeitszimmer_jo_temperature.last_updated %}
                {% set time_difference = as_timestamp(now()) - as_timestamp(last_updated) %}
                {% if time_difference > 1800 %}
                  color: orange;
                {% endif %}
              }
    title: Temperatur / Luftfeuchtigkeit
    state_color: false

finally hours later I got it:

card_mod:
  style:
    hui-generic-entity-row:
      $: |
        .info.pointer .secondary ha-relative-time {
          color: red;
        }
      .: |
        .entities-row div.entity:nth-child(1) {
          color: green;
        }
        .entities-row div.entity:nth-child(2) {
          color: orange;
        }
