Edit Style of Payment Item Field

Hi all, weird question for you!

Im not able to customize the style of the price in the payment field in my form. All my other question labels/boxes look great, but then the final field is a payment item field with text (e.g. price of the product) and this text is different colour and the stripe card input box looks very strange (it has a border of the correct colour, but then inside the border where the card details go is a bit of the background colour and a bit of white.

Is it possible to amend these bits or is it a limitation? screenshot of the weirdness below.
