Tabs not working

Hi jmthom3!

I added following code to functions.php file of your child theme in Appearance > Editor

function modify_jquery() {
if (!is_admin()) {
	wp_deregister_script('jquery');
	wp_register_script('jquery', 'https://code.jquery.com/jquery-1.11.3.min.js');
	wp_enqueue_script('jquery');
}
}
add_action('init', 'modify_jquery');

Please refresh your page and review your website now.

You have added it to style.css file. It should not be there. You also have Facebook code there, please move it out of style.css file as well. You can add it to a text widget or text block element

Cheers!
