The labels that we will display have different backgrounds and are defined in the order they are placed from left to right and top to bottom:

import tkinter as tk

class App(tk.Tk):
    def __init__(self):
        super().__init__()
        label_a = tk.Label(self, text="Label A", bg="yellow")
        label_b = tk.Label(self, text="Label B", bg="orange")
        label_c = tk.Label(self, text="Label C", bg="red")
        label_d = tk.Label(self, text="Label D", bg="green")
        label_e = tk.Label(self, text="Label E", bg="blue")

        label_a.place(relwidth=0.25, relheight=0.25)
        label_b.place(x=100, anchor=tk.N,
                      width=100, height=50)
        label_c.place(relx=0.5, rely=0.5, anchor=tk.CENTER,
                      relwidth=0.5, relheight=0.5)
        label_d.place(in_=label_c, anchor=tk.N + tk.W,
                      x=2, y=2, relx=0.5, rely=0.5,
                      relwidth=0.5, relheight=0.5)
        label_e.place(x=200, y=200, anchor=tk.S + tk.E,
                      relwidth=0.25, relheight=0.25)

if __name__ == "__main__":
    app = App()
    app.mainloop()

If you run the preceding program, you can see the overlapping between label_c and label_d in the center of the screen, something that we have not achieved with other geometry managers.
