Child Theme style.css not working

I am not able to see the changes that I’ve made in the child theme style.css. I’ve activated my child theme for Optimizer Pro 3.8. I’ve tried many of the suggestions in the wordpress forums and I’m not having any luck. I’m using XAMPP on my local laptop. Any ideas? Below is my child style.css

Theme Name:  CIT
Description:  Create IT Consulting, LLC magnificent child theme
Author:  Create IT Consulting, LLC.   Jessica Rhoades
Version:  1.0
Template:  Optimizer_pro

/*@import url('../optimizer_pro/style.css');  - no longer used due to caching issues

<?php
function theme_enqueue_styles() {

    $parent_style = 'parent-style';

    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 )
    );
}
add_action( 'wp_enqueue_scripts', 'theme_enqueue_styles' );

/*
body {
    border: 10px solid red !important;
}
*/

/* Contact Form 7 Styles

.wpcf7 {
background-color: #F1F1F1;
border: 25px solid #666666;
}

.wpcf7-form {
margin-left: 25px;
margin-right: 25px;
margin-top: 25px;
}

.wpcf7-textarea {
 width: 85%;
}

.wpcf7 input {
width: 50%;
}

.wpcf7-text {
width: 50%;
border: 10px solid;
}

?>

This is my functions.php in my child theme.

<?php

function enqueue_parent_theme_style() {
wp_enqueue_style( 'parent-style', get_template_directory_uri().'/style.css' );
add_action( 'wp_enqueue_scripts', 'enqueue_parent_theme_style', PHP_INT_MAX);
}

function enqueue_child_theme_style() {wp_enqueue_style( 'child-style', get_stylesheet_directory_uri().'/style.css' );}
add_action( 'wp_enqueue_scripts', 'enqueue_child_theme_style', 100 );
?>
