Exec/Script custom module - How to CSS the output format?

[diogofd8]

So, I was trying my best at a weather module. Nothing fancy, my script outputs 3 variables: a glyph/icon with the weather condition, the temperature and the unit (ºC)

I was expecting it to be personalized to look something like this. All the passing and font manipulation is required to ensure the center modules are "centered".

    "custom/wttr": {
        "format": "{}",
        "exec": "$HOME/.config/waybar/scripts/weather.sh",
        "return-type": "json",
        "interval": 1800
    }

I started here, but I didn't like how I couldn't fine control the output format so I ended up using 3 text 'fake weather' modules to help myself with a visual and now I'm everywhere looking for help to make this possible. I know I could call the weather script twice, once for the temperature, another for the icon, and still have my formatting, but I'm here wondering if it is possible that the exec json returns two classes or two objects instead of one.
This is how I got to the image I've shared.

    "custom/glyph": {
        "format": "󰖔",
        "tooltip": false
    },

        "custom/value": {
        "format": "15",
        "tooltip": false
    },
        "custom/unit": {
        "format": "ºC",
        "tooltip": false
    }

    #custom-glyph {
        font-family: 'IosevkaTerm Nerd Font Propo';
        font-size: 18px;
        color: ;
        padding-right: 6px;
    }
    
    
    #custom-value {
        font-family: 'JetBrains Mono';
        font-size: 14px;
        background-color: ;
    }
    
    
    #custom-unit {
        font-family: 'JetBrains Mono';
        font-size: 14px;
        letter-spacing: -1px;
        background-color: #custom-glyph {
        font-family: 'IosevkaTerm Nerd Font Propo';
        font-size: 18px;
        color: ;
        padding-right: 6px;
    }

I hope I can really do this. Any idea for a workaround that does not involve calling the script twice, once for the glyph, another for the temperature, and keeping the text module with the unit?
