Unity’s UI Toolkit is a collection of features, functionality, resources, and tools for developing user interfaces (UI). You can use UI Toolkit to develop custom UI and extensions for the Unity Editor, runtime debugging tools, and runtime UI for games and applications.
UI Toolkit is inspired by standard web technologies. If you have experience developing web pages or applications, much of your knowledge might be transferable, and many of the core concepts might be familiar.
