Create a WordPress template without navigation and footer

Question

As the title suggests, I'd like a page template to have NO navigation and NO footer.

All my page templates have this:

<?php
 /*
   * Template Name: Blah Blah
 */

 if (!defined('ABSPATH'))
  exit; // Exit if accessed directly
 get_header();
 ?>

But if I remove the above code then the entire page won't work.

Answer 1

Don't remove get_header().

Duplicate the header.php to header-{custom-name}.php, let's say (header-nonavfooter.php) then in the template file replace get_header() with get_header('nonavfooter').

In the new header file (header-nonavfooter.php) remove the code related to navigation.

Do the same for the footer.php also(Create a new footer.php and remove the footer parts that you don't need), remember not to remove wp_footer() available in footer.php.
