Child Themes and Theme Structure

How to create a child theme

• Create a folder in your themes directory giving it the name of new theme.
• Create style.css file and print this inside where template references the name of the parent theme that’s referenced in enqueue:

Theme Name:   Theme Name Here
Theme URI:    https://www.themeurl.com/
Description:  A Parent child theme 
Author:       Christine Wilson
Author URI:   https://www.christinewilson.ca
Template:     twentytwentyone
Version:      1.0.0
Text Domain:  themenamehere

• Create a file called functions.php and add enqueue scripts info:

/* enqueue scripts and style from parent theme */
    
function main_scripts() {
    wp_enqueue_style( 'themenamehere', get_stylesheet_uri(),
    array( 'twenty-twenty-one-style' ), wp_get_theme()->get('Version') );
}
add_action( 'wp_enqueue_scripts', 'main_scripts');
