Cross-Origin Preview Page Integration
The UI Theme Designer is an SAP tool that allows developers to create and customize themes for SAP UI applications. A cross-origin preview enables developers to see how their custom themes render on an application hosted on a different domain, helping to validate theme changes in a realistic environment. Developers use this configuration to test and refine theme designs before deploying them to production systems.

- Concept CSS Custom Properties for SAP Theming Theming in SAPUI5 is the mechanism by which the visual appearance of an application is controlled through [Cascading Style Sheets (CSS)](https://ui5.sap.com/#/topic/497c27a8ee26426faacd2b8a1751794a). Because SAPUI5 is an HTML library, developers use theming to apply and customize styles across UI components, ensuring a consistent look and feel. Tools such as the UI Theme Designer allow developers to extend theming further by adding cross-origin previews and custom styles.
