apply_filters( 'wpforms_stripe_api_payment_intents_set_config_element_style', array $styles )

Description

The wpforms_stripe_api_payment_intents_set_config_element_style filter lets you overwrite the Stripe Card Element style object. This allows you to adjust fonts, colors, sizes, and placeholder styling for the Stripe Credit Card field.

The style object uses CSS-like properties that map directly to Stripe Elements’ Style API. You can define a base style, as well as states like complete, empty, focus, or invalid.
