[Theme Nirvana] – Full-width template

I am using the Nirvana theme and would like to add a full-width page template to my child-theme. I have tried a lot of different things that I could find on the internet, without success. This is currently my full-width page template, with only the side-bar removed, although I have tried other things too. Could anyone please help me with this, it would be much appreciated!

<?php
/*
Template Name: Full Width
*/
get_header();
if ($nirvana_frontpage==”Enable” && is_front_page() && ‘posts’ == get_option( ‘show_on_front’ )): get_template_part( ‘frontpage’ );
else :
?>
<section id=”container” class=”<?php echo nirvana_get_layout_class(); ?>”>

<div id=”content” role=”main”>
<?php cryout_before_content_hook(); ?>

<?php get_template_part( ‘content/content’, ‘page’); ?>

<?php cryout_after_content_hook(); ?>
</div><!– #content –>
</section><!– #container –>

<?php
endif;
get_footer();
?>
