Child Theme files – what is needed?

Yes you will need to enqueue parent theme styles into child theme. Adding style.css in child theme will not automatically add parent theme’s styles too.

You can enqueue parent theme’s styles like this. Create a new functions.php in child theme and paste this.

function enqueue_child_theme_styles() {
    wp_enqueue_style( 'parent-style', get_template_directory_uri().'/style.css' );
    wp_enqueue_style( 'child-style', get_stylesheet_uri(), array('parent-style')  );
}
add_action( 'wp_enqueue_scripts', 'enqueue_child_theme_styles', PHP_INT_MAX);
