 * be injected in the web pages loaded by a #WebKitWebView, by
 * webkit_user_content_manager_add_style_sheet().
 *
 * To use a #WebKitUserContentManager, it must be created using
 * webkit_user_content_manager_new(), and then passed to
 * webkit_web_view_new_with_user_content_manager(). User style
 * sheets can be created with webkit_user_style_sheet_new().
 *
 * User style sheets can be added and removed at any time, but
 * they will affect the web pages loaded afterwards.
