   How to remove ver in URL?

   If you want to remove the ver parameter in URL (for example, to intentionally cache the file), you pass in null instead of false to remove that. For example:

   wp_enqueue_script('oxfam_js_cookie', 'https://cdnjs.cloudflare.com/ajax/libs/js-cookie/2.1.0/js.cookie.min.js', array(), null, true);

   By doing that, you will get:

   <script type='text/javascript' src='https://cdnjs.cloudflare.com/ajax/libs/js-cookie/2.1.0/js.cookie.min.js'></script>

   Load an IE-specific stylesheet:

   add_action( 'wp_enqueue_scripts', 'enqueue_my_styles' );
   function enqueue_my_styles() {
       
       global $wp_styles;
       
       // Load the main stylesheet
       wp_enqueue_style( 'my-theme', get_stylesheet_uri() );
       
       /**
        * Load our IE-only stylesheet for all versions of IE:
        * <!--[if IE]> ... <![endif]-->
        * 
        * NOTE: It is also possible to just check and see if the $is_IE global in WordPress is set to true before 
        * calling the wp_enqueue_style() function.  If you are trying to load a stylesheet for all browsers 
        * EXCEPT for IE, then you would HAVE to check the $is_IE global since WordPress doesn't have a way to 
        * properly handle non-IE conditional comments.
        */
       wp_enqueue_style( 'my-theme-ie', get_stylesheet_directory_uri() . "/css/ie.css", array( 'my-theme' )  );
       $wp_styles->add_data( 'my-theme-ie', 'conditional', 'IE' );
   }

   This is a conditional loading of css file by page template (css will be loaded on on the pages with tamplate-name.php).
   You can change the condition by another one.
   The code should be used in your theme’s function.php.
   Notice: The code works for child themes. If you want to use it in a parent theme replace get_stylesheet_directory_uri() with get_stylesheet_uri().

   $handle = 'wpdocs';
   wp_register_style( $handle, get_stylesheet_directory_uri().'/relative/path/to/stylesheet.css', array(), '', true );
   if ( is_page_template( 'template-name.php' ) ) {
   	wp_enqueue_style( $handle );
   }

   Enqueues should not be protocol specific, remove https. I have update code as below

   wp_enqueue_script('oxfam_js_cookie', '//cdnjs.cloudflare.com/ajax/libs/js-cookie/2.1.0/js.cookie.min.js', array(), null, true);

   For proper versioning based on the file’s last modified time, you can use something similar to:

   wp_enqueue_style('main-styles', get_template_directory_uri() . '/css/style.css', array(), filemtime(get_template_directory() . '/css/style.css'), false);

   When the style.css file is updated on the server, WP will append the appropriate timestamp.

   Note: You shouldn’t ever use time() as the 4th parameter or append it to the file, as this will break caching in almost all cases.
