Payment Page's native form builder exposes appearance controls under Style, with the live payment-form preview beside them. When using the Elementor widget, Elementor's page-level controls are organized under Content, Style, and Advanced.
1. Bring out your style.
- Choose Container Settings, Global Options, Pricing Plans, Payment Method Tabs/Buttons, Form, Filter - Switcher, Filter - Dropdown, Submit Button, or Dynamic Message.
- Expand a section to edit the controls for that part of the native payment form.

For an Elementor page, use the capabilities available in the installed Elementor plan for page-level spacing, backgrounds, borders, positioning, responsive visibility, attributes, or custom CSS.
Click Publish or Update in the WordPress Payment Form editor to save native-form changes. If the form is embedded on an Elementor page, publish or update the Elementor page separately after changing the page layout.
