Child theme not working

Hello,

I reviewed a lot of the forums about fixing the child theme but for some reason, I still cannot get my stylesheet to override parent theme.

Here’s the link to my site:

I am using theme Less. And created a child theme folder.
Here’s the code for style.css:

/*
 Theme Name:   Less Child
 Theme URI:    https://lessmade.com/themes/less/
 Description:  Less Child Theme
 Author:       Lucia Hsieh
 Author URI:   https://luciahsieh.ca

 Tags:         A super simple theme that can be customized using LESS variables
 Text Domain:  Less-child
*/

@import url('https://fonts.googleapis.com/css?family=Merriweather|Montserrat');

/*Changing fonts*/
body, button, input, select, header #brand h1 {
    font-family: 'Montserrat', Arial, sans-serif;
}

h1,h2, h3, h4, h5, h6, pre {
    font-family: 'Merriweather', Georgia, serif;
}

h1 {
	display: none;
}

Here’s for functions.php

<?php
add_action( 'wp_enqueue_scripts', 'my_theme_enqueue_styles' );
function my_theme_enqueue_styles() {
    wp_enqueue_style( 'parent-style', get_template_directory_uri() . '/style.css' );

}
?>

What am I doing wrong?

Thanks in advance!
