[child theme] Can't manage to make it work

Hi everyone

I’ve been trying a lot to make this child theme work but I can’t succeed.
That’s what I did:
in my ftp wp-content>themes I created the child theme folder

I then used Mac’s texteditor to create two files: a style.css file and a function.php

In the style.css file I just pasted this code:

/*
Theme Name: ??Resonar Child
Theme URI: ???https://www.riccardocavaliere.com/resonar-child/
Description: ?Resonar Child Theme
Author: ??????Riccardo Cavaliere
Author URI: ??https://riccardocavaliere.com
Template: ????resonar
Version: ?????1.0.0
License: ?????GNU General Public License v2 or later
License URI: ?https://www.gnu.org/licenses/gpl-2.0.html
Tags: ????????light, dark, two-columns, right-sidebar, responsive-layout, accessibility-ready
Text Domain: ?resonar-child
*/

in the function.php file I wrote:

<?php

add_action( 'wp_enqueue_scripts', 'enqueue_parent_theme_style' );
function enqueue_parent_theme_style() {
    wp_enqueue_style( 'parent-style', get_template_directory_uri().'/style.css' );
}

I uploaded both the files into my child theme folder but the child theme is not working properly, as you can see if you check my website:

What did I do wrong?

When I did the same operation but using the @import function (and without the function.php) everything worked smoothly.

Thansk in advance
