public IStyle style { get; }

The returned style data, computed from USS files or inline styles written to this object in C#, doesn't represent the fully resolved styles, such as the final height and width of a VisualElement. To access these fully resolved styles, use _resolvedStyle.

For information about how to use this property and all the supported USS properties, refer to the Apply styles in C# scripts and USS properties reference manual pages.
