How to make full-width page?

Hello,

I’m trying to make a full-width page for this theme: http://www.artofblog.com/33-a-dream-to-host/

It doesn’t have full-width page in the theme, so I decided to create a new one. However, I cannot find any “DIV” from the page.php

This is the code in page.php

<?php get_header(); ?>

	<?php if (have_posts()) : while (have_posts()) : the_post(); ?>

		<h1 id="post-<?php the_ID(); ?>"><?php the_title(); ?></h1>

			<?php the_content('<p class="serif">Read the rest of this entry &raquo;</p>'); ?>
        	<?php wp_link_pages('before=<p>&after=</p>&next_or_number=number&pagelink=page %'); ?>

		<?php edit_post_link(__('Edit'), '<p>', '</p>'); ?>
  		<?php comments_template(); ?>
			<?php endwhile;else : ?>
		<h2><?php _e('Not Found'); ?></h2>

		<p><?php _e('Sorry, but the page you requested cannot be found.'); ?></p>

		<h3><?php _e('Search'); ?></h3>

			<?php include (TEMPLATEPATH . '/searchform.php'); ?>

			<?php endif; ?>

<?php get_sidebar(); ?>

<?php get_footer(); ?>

I followed this (http://wpmu.org/create-a-full-width-page-for-wordpress-in-5-simple-steps/) technique, but couldn’t find DIV’s.

Any suggestions to get a full-width page for this theme?

Cheers,
Mike
