Stripe elements styling

This is what i added in Custom CSS
.StripeElement {
box-sizing: border-box;
height: 40px;
padding: 10px 12px;
border: 1px solid transparent;
border-radius: 4px;
background-color: white;
box-shadow: 0 1px 3px 0 #e6ebf1;
-webkit-transition: box-shadow 150ms ease;
transition: box-shadow 150ms ease;
}

That's better but how can I get a little space between the Strip/PayPal and the fields like yours has?

Custom CSS
.jd_predefined_box
{
width:98% !important;
}

Sorry, I meant space on the top. Your demo site has a about 20px space above the shadowed field container.

#stripe-card-form {
margin-top: 1rem;
}
