  • string|bool $src: Path to the stylesheet from the root directory of WordPress. Example: ‘/css/mystyle.css’.
  • array $deps: Array of handles of any stylesheet that this stylesheet depends on. (Stylesheets that must be loaded before this stylesheet.) Pass an empty array if there are no dependencies.
