A search and replace solution does sound viable. I wouldn’t do it via JavaScript, though. add_filter(‘the_title’, ‘wpse60174_logo_in_title’, 10, 2); function wpse60174_logo_in_title($title, $post_id) { // Add a <span> around the company name return preg_replace(‘~\bCompany\s+Name\b~i’, ‘<span class=”company”>$0</span>’, $title); } With the extra span in place it is just a matter of applying some custom styles to it. … Read more
