The functional concept of i3 corresponds to a tree structure, the individual nodes of which the window manager treats as containers.
Starting from the X11 root window, which as the primary container forms the background for all other levels, the following hierarchies branch out to the X11 window container, which represents a single window as the end point.
The containers represent a wide variety of functions: They can consist of an empty workspace or a workspace with only one open window and contain several application windows as a divided container. The layout of the tree is therefore not static, but changes constantly.
