In order to create a Child theme we need to add a minimum of two files

Create a new folder which will hold your child theme files and create a file called style.css which contains the following code:

/*
Theme Name: Your Child Theme Name
Theme URI: https://yourwebsite.com/
Author: Your Name
Author URI: https://yourwebsite.com/
Description: A child theme of [Parent Theme Name]
Template: [Parent Theme Name] // Replace with the actual parent theme name
Version: 1.0.0
License: GNU General Public License v2 or later
License URI: https://www.gnu.org/licenses/gpl-2.0.html
Text Domain: [Your Child Theme Text Domain] // Optional, for translations Use the same in your functions
*/

Note: Remove the the sections that include “//” and following text.

You will then need to create a file named “functions.php” and include the following code:

<?php

// Load Parent Styles from the main theme into the child theme
function my_theme_enqueue_styles() {
    wp_enqueue_style( 'parent_theme_style', get_template_directory_uri() . '/style.css' );
    wp_enqueue_style( 'child_theme_style', get_stylesheet_uri() );
}
add_action("wp_enqueue_scripts", "my_theme_enqueue_styles");


?>

After that your Child Theme will be accessible in the Appearance > Themes Page
