 **Create a CSS file:/assets/css/custom.css**


 Enqueue it:

 add_action('wp_enqueue_scripts', function () {
     wp_enqueue_style(
         'custom-css',
         get_stylesheet_directory_uri() . '/assets/css/custom.css',
         [],
         '1.0'
     );
 });


 Put your CSS inside custom.css:

 @property --animate {
   syntax: "<custom-ident>";
   inherits: true;
   initial-value: false;
 }
