<stripe-elements>

Polymer wrapper for Stripe.js v3 Elements. Creates a card element such as https://stripe.com/docs/elements

Usage

  <paper-input label="Stripe Publishable Key" value="{{key}}"></paper-input>
  <stripe-elements publishable-key="[[key]]" token="{{token}}"></stripe-elements>
  <show-json hide-copy-button json="[[token]]"></show-json>

Styling

You can use the --paper-button mixin to apply styles to the submit button, e.g.

stripe-elements {
  --paper-button: {
    background-color: blue;
    color: white;
  }
}

A word about nomenclature before we list custom properties and mixins. Stripe v3 Introduces 'Stripe Elements'. These are not custom elements, but rather forms hosted by stripe and injected into your page via an iFrame. When we refer to the 'Stripe Element' in this document, we are referring to the hosted Stripe form, not the <stripe-element> custom element.

The following custom properties and mixins are available for styling the <stripe-elements> component:

Custom property	Description	Default
--stripe-elements-element	Mixin applied to the Stripe Element	{}
--stripe-elements-element-focus	Mixin applied to the Stripe Element in its focussed state.	{}
--stripe-elements-element-invalid	Mixin applied to the Stripe Element in ins invalid state	{}
`--stripe-elements-element-webkit-autofill	Mixin applied to the Stripe Element's webkit autofill.	{}

When you apply CSS to the custom properties below, they're parsed and sent to Stripe, who should apply them to the Stripe Element they return in the iFrame. Base styles are inherited by all other variants. complete styles are applies when the Stripe Element has valid input. empty styles are applied when the Stripe Element has no user input. invalid styles are applied when the Stripe Element has invalid input.
