Customizing Stripe payment gateway css

[Dezso Kovi]

Hey guy's. I have a custom theme installed on my whmcs, and we use stripe as a payment platform. Currently everything is themed correctly except for the card input text. I have tried changing a load of things in my css, including opening a ticket with whmcs, which what they suggested did not work.

 

Whmcs staff suggested adding this to my custom.css, and it did nothing

#order-standard_cart .prepend-icon .field {
  color:#fff;
}

As you can see from the screenshots, the fields look fine with the default information, but as soon as you start adding your card the text turns black, and then red when the card is not real. I just want to know how I can turn the black to white.
