# CustomTkinter ![](https://raw.githubusercontent.com/TomSchimansky/CustomTkinter/master/documentation_images/customtkinter_mode_switch.gif) With CustomTkinter you can create modern looking user interfaces in python with tkinter. CustomTkinter is a tkinter extension which provides extra ui-elements like the CTkButton, which can be used like a normal tkinter.Button, but can be customized with a border and round edges. CustomTkinter also supports a light and dark theme, which can either be set manually or get controlled by the system appearance mode (only macOS).
