Center An Object In Liquid ( Order Printer)

Hello,
Is there a way to center an Object in Liquid (Shopify Order printer)
I’ve been trying to put the Billing Detail in the Center of the section, but could not find the way.

And how can we add to total quantity for my template ?

Thank you for your help!
Here’s what I have

{% if shipping_address %}

Shipping Details

{{ shipping_address.name }}
{{ shipping_address | format_address }}
{{ shipping_address.phone }}
{% endif %}

{% if billing_address %}

Billing Details

{{ billing_address.name }}
{{ billing_address | format_address }}
{{ billing_address.phone }} {% endif %}
