How to change the font size of the amount in the product items?

Hi

Thanks very much for your previous help.  The custom CSS worked perfectly.

Now I need the code to change the font size in the snip below.  

Thank you!

You can inject the CSS code below to change the font size in your screenshot. Just adjust the px according to your preferred size.

span.form-product-details {

    font-size: 10px;

}
