How to change the size of a certain button in CKEDITOR?

Question

JavaScript

CKEDITOR has a "Font Size" button. Maybe for "Size" its length would fit. But for Russian content - no. Question - how to correctly change its width? In styles, everything is minimized. It seems to me that getting into the standard css and changing it is the wrong option, which can and should be done somehow differently. How to do it?

Answer 1

in css
there is a main css file, minimized, you need to find a class that sets the default value and write your own, that is, hack this file and then remember about it when updating
