Which property allows you to view the CSS properties of items in your application?

The Visual CSS Editor is the tool that enables you to view and edit the CSS properties of elements within your application. This feature provides a user-friendly interface where developers can manipulate CSS styles directly. It typically includes various options to modify visual aspects such as colors, margins, padding, and more, facilitating a more visual approach to styling without needing to directly edit CSS files.

In contrast, other options do not specifically refer to the functionality of visualizing CSS properties with the same clarity. For instance, the Style Editor often focuses on defining styles rather than visualizing existing styles. The Styles Property pertains to individual items but does not provide a collective overview of CSS styles. The Style Viewer, while it seems to suggest a visualization, is not a standard term associated with CSS editing or viewing in OutSystems, thus making the Visual CSS Editor the most suitable choice for this functionality.
