The root of the problem is that you are unknowingly using the Frame class from the ttk package rather than from the tkinter package. The one from ttk does not support the background option.

This is the main reason why you shouldn't do global imports -- you can overwrite the definition of classes and commands.

I recommend doing imports like this:

import tkinter as tk
import ttk

Then you prefix the widgets with either tk or ttk :

f1 = tk.Frame(..., bg=..., fg=...)
f2 = ttk.Frame(..., style=...)

It then becomes instantly obvious which widget you are using, at the expense of just a tiny bit more typing. If you had done this, this error in your code would never have happened.

You use ttk Frame  bg option does not work for it   You should create style and apply it to the frame   from tkinter import   from tkinter ttk import     root   Tk    s   Style   s configure  My TFrame   background  red    mail1   Frame root  style  My TFrame   mail1 place height 70  width 400  x 83  y 109  mail1 config   root mainloop
