I use CKEditor 4 and I want to set default font. I added \"font_defaultLabel\" with my font choice but it doesn\'t work ...
I found this solution on the Internet but
Simply place this below your original CKEDITOR JS, and change the font-size to whatever you like. This works for me, hope it does for you!
CKEDITOR.on( 'instanceReady', function( ev ) { ev.editor.setData(''); });
