// Proper way to enqueue styles (from https://codex.wordpress.org/Function_Reference/wp_enqueue_script)
function wpse182193_load_style() {
    wp_register_style( \'my-stylesheet\', get_stylesheet_directory_uri() . \'/css/jquery-ui_002.css\', array(), \'\');
    wp_enqueue_style( \'my-stylesheet\' );

add_action( \'wp_enqueue_scripts\', \'wpse182193_load_style\' );
