How to override parent style.css in woocommerce? Function.php file problem - php

Question

This is what bothers me.
This is my functions.php:
<?php
// Exit if accessed directly
if ( !defined( 'ABSPATH' ) ) exit;
// BEGIN ENQUEUE PARENT ACTION
// AUTO GENERATED - Do not modify or remove comment markers above or below:
if ( !function_exists( 'chld_thm_cfg_parent_css' ) ):
function chld_thm_cfg_parent_css() {
wp_enqueue_style( 'chld_thm_cfg_parent', trailingslashit( get_template_directory_uri() ) . 'style.css', array( 'avada-stylesheet','avada- max-2c','avada-min-2c-max-3c','avada-min-3c-max-4c','avada-min-4c-max-5c','avada-min-5c-max-6c','avada-min-768-max-1024-p','avada-min-768-max-1024-l','avada-max-shbp-18','avada-max-shbp-32','avada-max-640','avada-min-768-max-1024-woo' ) );
}
endif;
add_action( 'wp_enqueue_scripts', 'chld_thm_cfg_parent_css', 10 );
if ( !function_exists( 'child_theme_configurator_css' ) ):
function child_theme_configurator_css() {
wp_enqueue_style( 'chld_thm_cfg_child', trailingslashit( get_stylesheet_directory_uri() ) . 'style.css', array( 'chld_thm_cfg_parent' ) );
}
endif;
add_action( 'wp_enqueue_scripts', 'child_theme_configurator_css', 20 );
// END ENQUEUE PARENT ACTION
An this is my style.css file in my child theme:
/*
Theme Name: Avada Child
Theme URI: http://avada.theme-fusion.com/
Template: Avada
Author: ThemeFusion
Author URI: http://themeforest.net/user/ThemeFusion
Description: The #1 selling theme of all time that allows you to build virtually any design style.

.woocommerce-message {
padding-left: 18px;
background-color: #252a33;
border-top: 1px solid rgba(128,128,128,1);
border-top-color: rgb(128, 128, 128);
border-bottom: 1px solid rgba(128,128,128,1);
border-bottom-color: rgb(128, 128, 128);
color: rgba(128,128,128,1);
}
My goal is to change background-color, but it doesn't work ... I used Child Theme Configurator plugin to make a child theme, and I think that plugin is responsible for that how function.php looks like...
Please help.
