What is the correct term for applying a Theme to a specific part of an OutSystems application?

In OutSystems, applying a Theme to a specific part of an application can indeed pertain to either a Module or a UI Flow. This flexibility allows developers to manage the graphical appearance and user interface components consistently across different segments of the application.

When a Theme is applied at the Module level, it affects all screens and UI elements within that module, ensuring a uniform look and feel throughout the module's functionalities. On the other hand, applying a Theme to a UI Flow allows for a more targeted approach, letting developers customize the theme for distinct user journeys or specific parts of the application. This means that within a single Module, there can be various UI Flows each presented uniquely if desired.

Since both Modules and UI Flows can be themed independently, knowing that either can be the correct context for applying a Theme is essential for creating a visually appealing and cohesive user experience in OutSystems applications. Therefore, this option encapsulates the versatility offered by the platform in designing user interfaces effectively.
