		$slug		= $post_object->post_name;
		$content 	= $post_object->post_content;
		$hlevel		= count(get_post_ancestors($post_object->ID))+1;
	?>

		<section id="<?php echo $slug; ?>" class="<?php hybrid_entry_class(); ?>">
			<?php echo "<h" . $hlevel . ">"; echo $title; echo "</h" . $hlevel . ">"; ?>
			<?php echo apply_filters( 'the_content', $content); ?>
		</section>

<?php endforeach; ?>
