function quickedit_library_info_alter

Implements hook_library_info_alter().

Includes additional stylesheets defined by the admin theme to allow it to customize the Quick Edit toolbar appearance.

An admin theme can specify CSS files to make the front-end administration experience of in-place editing match the administration experience in the back-end.

The CSS files can be specified via the "edit_stylesheets" property in the .info.yml file:

quickedit_stylesheets:
-css / quickedit . css;
