Child Theme Problems

Hi,

Can you help me? I think my parent theme is loading after my child theme. I’ve tried the suggestions on the forum but its still not changing the nav bar colours specified in the child, even if add !important, which I know is not good practice but wanted to test it. My site is :amberleyschool.co.uk.

My child theme:
/*
Theme Name: Twenty Thirteen Child
Theme URI: https://amberleyschool.co.uk/wp-content/themes/twentythirteen_child/
Description: Twenty Thirteen Child Theme
Author: Tracey Vincent
Author URI: https://amberleyschool.co.uk
Template: twentythirteen
Version: 1.0.0
License: GNU General Public License v2 or later
License URI: https://www.gnu.org/licenses/gpl-2.0.html
*/
@import url(“../twentythirteen/style.css”);
/* =Theme customization starts here */

My functions.php:
<?php
function theme_enqueue_styles() {

$parent_style = ‘twentythirteen’;

wp_enqueue_style( $parent_style, get_template_directory_uri() . ‘/style.css’ );
wp_enqueue_style( ‘twentythirteen_child’,
get_stylesheet_directory_uri() . ‘/style.css’,
array( $parent_style )
);
}
add_action( ‘wp_enqueue_scripts’, ‘theme_enqueue_styles’ );
?>
Any ideas?

Thank you
