Common Properties are applied to SmartStudio objects to set their position, size, and visibility.
Anchor Point: This is a reference point inside a selected object that is used to position the object on the x and y axes. You can choose an anchor in the center of the object, on the edges, or in the corners.
X and Y Position: These specify the position of a selected object on the x (horizontal) and y (vertical) axes, using the object's anchor point for reference.
Width and Height: These specify the width and height of a selected object.
Opacity: This specifies the opacity (or "alpha") of a selected object, with 0% being completely transparent and 100% being completely opaque.
