Hello There,
Thanks for updating in!
1.) Are you using Cornerstone in creating your portfolio item? If not, then you must make use of the responsive text shortcode and add it in your portfolio item content description. You can check out the shortcode here: http://demo.theme.co/integrity-1/shortcodes/responsive-text/
2.) Because what you are trying to accomplish requires a template customization, we would highly to suggest that you use a child theme. This allows you to make code changes that won’t be overwritten when an X update is released. After your child theme is setup, please review how we recommend making template changes in Customization Best Practices.
After the child theme is set up, please add the following code in your child theme’s functions.php file
// Custom Social Output

if ( ! function_exists( 'x_social_global' ) ) :
function x_social_global() {
