function hook_ckeditor_css_alter

Modify the list of CSS files that will be added to a CKEditor instance.

Modules may use this hook to provide their own custom CSS file without providing a CKEditor plugin. This list of CSS files is only used in the iframe versions of CKEditor.

Front-end themes (and base themes) can easily specify CSS files to be used in iframe instances of CKEditor through an entry in their .info file:

ckeditor_stylesheets[] = css / ckeditor - iframe . css;

Parameters

array &$css: An array of CSS files, passed by reference. This is a flat list of file paths relative to the Drupal root.

$editor: The text editor object as returned by editor_load(), for which these files are being loaded. Based on this information, it is possible to load the corresponding text format object as returned by filter_format_load().
