Hi Daniel,
Yes, we can take a look. The code you added is just CSS. You’ll also need PHP to add the comment count in a single Post’s meta.
Try adding this:
add_filter( 'generate_header_entry_meta_items', function( $items ) {
$items[] = 'comments-link';
return $items;
} );
add_action( 'wp', function() {
if ( is_single() ) {
add_filter( 'generate_show_comments', '__return_true' );
}
} );
