Some Tpl Help Needed

{__("text_cart_min_qty", ["[product]" => $product.product, "[quantity]" => $product.min_qty])}.

The code is such and it produce "minimum order quantity" ex "100" how can I give description one class and number second class?

On the Administration -> Languages -> Translations page find the text_cart_min_qty language variable and add necessary tags with classes there
