hook_ckeditor_css_alter(array &$css, Editor $editor)
Modify the list of CSS files that will be added to a CKEditor instance.
Modules may use this hook to provide their own custom CSS file without providing a CKEditor plugin. This list of CSS files is only used in the iframe versions of CKEditor.
Front-end themes (and base themes) can easily specify CSS files to be used in iframe instances of CKEditor through an entry in their .info.yml file:
ckeditor_stylesheets: - css/ckeditor-iframe.css
Parameters
array &$css: An array of CSS files, passed by reference. This is a flat list of file paths which can be either relative to the Drupal root or external URLs.
$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.
