Is my child theme working properly

Question

A few days ago I created a child theme of my theme zerif lite. Everything is looking good and there is no problem at all.

I just want to know are the created functions.php and style.css files correct or not. And I added some optimized files in my child theme which are already exist in parent theme (Unoptimized but same files), but i am in doubt that same files are loading 2 times from parent and child theme. I want to be sure that same files not load 2 times.

This is my style.css of child theme:

/*
Theme Name:   Zerif Lite Child
Theme URI:    http:/only4gamers.ml
Description:  Zerif Lite Child Theme
Author:       Md Umar
Author URI:   http:/only4gamers.ml
Template:     zerif-lite
Version:      1.0.0
License:      GNU General Public License v2 or later License URI:  http://www.gnu.org/licenses/gpl-2.0.html
Tags:         light, dark, two-columns,right-sidebar, responsive-layout, accessibility-ready Text Domain:  zerif-lite-child
*/

and this is function file of child theme:

<?php  
function my_theme_enqueue_styles() {  

    $parent_style = 'zerif-style';  

    wp_enqueue_style( $parent_style, get_template_directory_uri() . '/style.css' );  
    wp_enqueue_style( 'child-style',  
        get_stylesheet_directory_uri() . '/style.css',  
        array( $parent_style ),  
        wp_get_theme()->get('Version')  
    );  
}  
add_action( 'wp_enqueue_scripts', 'my_theme_enqueue_styles' );  
?>  

I am new to wordpress and don't know much about coding. Any improvement in my style and function file is highly appreciated.

There's a simple way to test:

• add wp_die('it works'); to functions.php, if you see it works on every page, then it's worked
• add a silly CSS rule to style.css, e.g. body { border: 100px solid pink; }, if your pages now have a 100 pixel pink border then your stylesheet is working

If it works, then you did it correctly, if you didn't do it the correct way, it wouldn't work.

Otherwise, the only thing's I'd note are that:

• it's functions.php not function.php
• avoid closing PHP tags in functions.php, PHP will auto-add them if needed, and it prevents a common mistake with whitespace after the tag
• my_theme is a very generic prefix, you should pick something more unique
