Hi There,
See the following guide first:
The title is part of this file: wp-content\themes\x\framework\legacy\cranium\headers\views\ethos\ _landmark-header.php. See the filter for x_is_portfolio() function on the file. Now to move that title on the new position, we have to move the content inside that filter to the template that display portfolio item which is this: \wp-content\themes\x\framework\views\ethos\ content-portfolio.php. The process is we have to copy the file we have to edit on the same folder of your child theme and then edit that file.
Hope this helps.
