Child Theme CSS Not Working Parent Still Showing

Hi all,
I am at my wit’s end! Cannot get my child theme CSS sheet to show and have tried:

@import
functions.php
!important

but nothing happens. I know CSS does work because I used a plugin and it rendered fine. I have the style sheet in a child theme folder, no subfolders. All named correctly.

Can someone take a look? Thank you so much in advance.

/////////////////

Here is the top of my css stylesheet:

/*
Theme Name: Button Child
Description: Customizations to Button Theme
Author: Pyrite Pixels
Author URI:
Template: button
Version: 1.0
*/
/* NOTES
Original accent color from another: #24890d
*/

p {
color: #40ba37 !important;
}

Here is the functions.php file:
<?php
/**
* button-child functions and definitions
*
* @package button
*/
/*
When transferring, Plugin Name: Site Plugin for mysite.com
Description: Site specific code changes for mysite.com
*/
/* Start Adding Functions Below this Line */

function my_theme_enqueue_styles() {

$parent_style = ‘parent-style’; // This is ‘twentyfifteen-style’ for the Twenty Fifteen theme.

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 ),
wp_get_theme()->get(‘Version’)
);
}
add_action( ‘wp_enqueue_scripts’, ‘my_theme_enqueue_styles’ );
