As you know ckeditor4 has alignment buttons. when you press on each button, it adds a default class.

rteleft for left, rteright for right, rtecenter for center and rtejustify for justify alignment.

I want to know a way to change these default css classes? for example for left align, I want to use uk-text-left or for center align, I want uk-text-center

I found the solution.

Just need to add this config to custom javascript confiurations in advanced section of ckeditor profile.

config.justifyClasses = [ 'uk-text-left', 'uk-text-center', 'uk-text-right', 'uk-text-justify' ];
