title: How many/What are the different types of ttk styles available?
body: <p>I've been making some GUIs recently and found the buttons looked rather bland so I read some tutorials on making the look better using ttk and got the following:</p>
  
  <pre><code>from tkinter import ttk
  from tkinter.ttk import *
  
  root = tkinter.Tk()
  
  style = ttk.Style()
  style.configure("BW.TLabel")
  
  btn = ttk.Button(text="Test")
  btn.pack()
  
  root.mainloop()
  </code></pre>
  
  <p>Yes it looks better but I was wondering if there are different ttk styles and if so, how many are there and where to check for them</p>
