Layout collapses in child theme creation

Restaurant Recipe’s child theme was made.
Described in style.css

/*
 Theme Name:   Restaurant Recipe Child Theme
 Template:     restaurant-recipe
 Description:  Restaurant Recipe Child Theme
 */

functions.php

<?php
add_action( 'wp_enqueue_scripts', 'theme_enqueue_styles' );
function theme_enqueue_styles() {
  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')
);
}

There is nothing in style.css. But the layout was broken.
See the image.

Do you officially distribute child themes?
What should I do?
