TKinter，将小部件放置在与背景图像对齐的窗口的某些部分

我想把我的按钮和文字整齐地放在“登录”框的范围内。“登录”框实际上是我用TKinter加载的背景PNG图像的一部分。我想把我的小部件放在后台的登录框里。我目前使用的是grid()，但由于某些原因，它们没有与登录框对齐。我如何调整我的代码得到登录框内的东西?

def build_login_screen(root):
    background_image = PhotoImage(file="./loginScreen.png", name="background_image")
    background_label = Label(root, image=background_image, name="background_label")
    background_label.place(x=0, y=0, relwidth=1, relheight=1)
    background_label.image = background_image
    login_button = Button(root, text="Login", name="login_button", command=lambda: login(root))
    login_button.grid(row=5, column=1)
    quit_button = Button(root, text="Quit", name="quit_button", command=root.destroy)
    quit_button.grid(row=8, column=1)
    server_select = Combobox(root, name='server_select')
    server_select['values'] = (remote_server, local_server)
    server_select.current(0)  
    server_select.grid(row=4, column=1)
    server_select.bind("<<ComboboxSelected>>", clickServer)
    label_server_status = Label(root, padx=50, text="Checking server status..", name="label_server_status")
    label_server_status.grid(row=4, column=2)
    label_server_status_value = Label(root, padx=50, text=server_availability, name="label_server_status_value")
    label_server_status_value.grid(row=4, column=3)
