Download this script and save it to the JS folder in your theme directory.

Add this code to your child theme’s functions.php file or via a plugin that allows custom functions to be added, such as the Dessky Snippets plugin. Please don’t add custom code directly to your parent theme’s functions.php file as this will be overwritten completely when you update the theme.

Remember to make sure the path matches your theme structure to enqueue it.
