There are two types of Frames in Framer X. Canvas-level frames and nested frames. Canvas-level frames behave like screens: you can select preset devices, customize its orientation and more. They get a white background color by default.
If you add another Frame within, it will get a semi-transparent blue background color. This is how you can differentiate nested Frames from canvas-level Frames.
There are four types of Frame properties:
|Generic||Opacity, Radius, Rotation, etc|
|Styling||Fill, Shadows, Blur, etc|
