Child Theme CSS not working :(

For whatever reason, the CSS for my child theme stopped working, any help would be much appreciated.

Here is the functions.php:

‘<?php

/*
*
* Joyn Functions – Child Theme
* ————————————————
* These functions will override the parent theme
* functions. We have provided some examples below.
*
*
*/

/* LOAD THEME LANGUAGE
================================================== */
/*
* You can uncomment the line below to include your own translations
* into your child theme, simply create a “language” folder and add your po/mo files
*/

// load_theme_textdomain(‘swiftframework’, get_stylesheet_directory_uri().’/language’);

/* REMOVE PAGE BUILDER ASSETS
================================================== */
/*
* You can uncomment the line below to remove selected assets from the page builder
*/

// function spb_remove_assets( $pb_assets ) {
// unset($pb_assets[‘parallax’]);
// return $pb_assets;
// }
// add_filter( ‘spb_assets_filter’, ‘spb_remove_assets’ );

/* ADD/EDIT PAGE BUILDER TEMPLATES
================================================== */
function custom_prebuilt_templates($prebuilt_templates) {

/*
* You can uncomment the lines below to add custom templates
*/
// $prebuilt_templates[“custom”] = array(
// ‘id’ => “custom”,
// ‘name’ => ‘Custom’,
// ‘code’ => ‘your-code-here’
// );

/*
* You can uncomment the lines below to remove default templates
*/
// unset($prebuilt_templates[‘home-1’]);
// unset($prebuilt_templates[‘home-2’]);

// return templates array
return $prebuilt_templates;

}
//add_filter( ‘spb_prebuilt_templates’, ‘custom_prebuilt_templates’ );

function custom_post_thumb_image($thumb_img_url) {

if ($thumb_img_url == “”) {
global $post;
ob_start();
ob_end_clean();
$output = preg_match_all(‘/<img.+src=[\'”]([^\'”]+)[\'”].*>/i’, $post->post_content, $matches);
if (!empty($matches) && isset($matches[1][0])) {
$thumb_img_url = $matches[1][0];
}
}

return $thumb_img_url;
}
add_filter( ‘sf_post_thumb_image_url’, ‘custom_post_thumb_image’ );

?>’

Here is the style.css:
