How can I put border styling with input component?

<CardElement style={{
  base: {
    fontSize: '18px',
    border: '1px solid red' // it is not work.
  } 
}} />

but, seems they didn't provide custom style interface, though.

Anyone know?

Update:

following are sample code that using StripeElement class to apply custom styling.

.StripeElement {
  border: 1px solid #eee;
}

.StripeElement--invalid {
  border: 1px solid red;
}

Great question! As noted here, to apply padding or a border to a Stripe element you want to style the parent DOM node that contains the element, not the element itself:

https://stripe.com/docs/elements/reference#the-element-container

I'd wrap your CardElement in a div and then apply styling to that. As noted above, Elements automatically applies the StripeElement class to the parent element, as well as complete/empty/focus/invalid states.
