My ckeditor WYSIWYG has the ability to create divs. I am trying to create a style that can be placed in the "Style" drop-down list:

Ive tried adding the following to my config.js, but it seems to have no effect.
CKEDITOR.stylesSet.add( 'default', [ // Inline styles { name : 'Titulo Explicacion Servicio', element : 'div', attributes : { 'class' : 'titulo_explicacion_servicio' } }, { name : 'Texto Explicacion Servicio', element : 'div', attributes : { 'class' : 'texto_explicacion_servicio' } }, { name : 'Texto Fondo Foto', element : 'div', attributes : { 'class' : 'intro_fondo_foto' } } ]);
I doubt this makes any sense, but this is about the Drupal site.
