This piece of code, is not part of the theme but I have uploaded it to the wp-content/themes/hitmag/page-cleanpage.php . To use it set the template of the page to be clean page and then configure the “Modal Dialog” plugin to use this page.
<?php
/**
* Template Name: Clean Page
* This template will only display the content you entered in the page editor
*/
?>
<head>
</head>
<?php
while ( have_posts() ) : the_post();
the_content();
endwhile;
?>
</body>
</html>
