如何使用 class ttk.Style 设置框架的背景？

Question

I'm making a tkinter interface and created a ttk.Style object to make it easy to change the design. However, when I try to change some characteristic of the frame or labelframe, I don't see changes in the widget.

import tkinter as tk
from tkinter import ttk

colors = [
    '#203864',
    '#ADB9CA'
]

myfont = ('calibri', 18)

root = tk.Tk()

style = ttk.Style()
style.theme_create('MyTheme', parent='alt', settings={
    'TFrame':{
        'configure':{'background':colors[0]}
    },
    'TLabel':{
        'configure':{'background':colors[0], 'font':myfont, 'foreground':colors[1]}
    }
})
style.theme_use('MyTheme')

frame = tk.Frame(root)
frame.pack()

tk.Label(frame, text='MyTheme').pack(padx=100, pady=20)

root.mainloop()

Sorry for my English, I'm learning.

The themes only work for ttk widgets, and your code is using a tk frame. You need to change your frame to this:

frame = ttk.Frame(root, width=100, height=100)
