Hi iacino
To create child theme your just need two main files style.css and functions.php in a new folder outside main theme’s folder.
Now in functions.php you need only below code to inherit parent style-sheet.
<?php
add_action( 'wp_enqueue_scripts', 'theme_enqueue_styles' );
function theme_enqueue_styles() {
wp_enqueue_style( 'parent-style', get_template_directory_uri() . '/style.css' );
}
And in style.css the below code is sufficient:
/*
Theme Name: Bizlight Child
Theme URI: https://evisionthemes.com/themes/bizlight
Author: evisiontheme
Author URI: https://evisionthemes.com/
Template: bizlight
