how to make the search result posts to be like the single post

hello,
i want the search result posts to be in the same css and in the same functions like the single posts.

what i need to change?

this is the search result.php

<?php
/**
 * The template for displaying Search Results pages
 *
 * @package WordPress
 * @subpackage Twenty_Twelve
 * @since Twenty Twelve 1.0
 */

get_header(); ?>

	<section id="primary" class="site-content">
		<div id="content" role="main">

		<?php if ( have_posts() ) : ?>

			<header class="page-header">
				<h1 class="page-title"><?php printf( __( 'Search Results for: %s', 'twentytwelve' ), '<span>' . get_search_query() . '</span>' ); ?></h1>
			</header>

			<?php twentytwelve_content_nav( 'nav-above' ); ?>

			<?php /* Start the Loop */ ?>
			<?php while ( have_posts() ) : the_post(); ?>
				<?php get_template_part( 'content', get_post_format() ); ?>
			<?php endwhile; ?>

			<?php twentytwelve_content_nav( 'nav-below' ); ?>

		<?php else : ?>

			<article id="post-0" class="post no-results not-found">
				<header class="entry-header">
					<h1 class="entry-title"><?php _e( 'Nothing Found', 'twentytwelve' ); ?></h1>
				</header>

				<div class="entry-content">
					<p><?php _e( 'Sorry, but nothing matched your search criteria. Please try again with some different keywords.', 'twentytwelve' ); ?></p>
					<?php get_search_fom(); ?>
				</div><!-- .entry-content -->
			</article><!-- #post-0 -->

		<?php endif; ?>

		</div><!-- #content -->
	</section><!-- #primary -->

<?php get_sidebar(); ?>
<?php get_footer(); ?>

and this s the single post.php code:

<?php
/**
 * The Template for displaying all single posts
 *
 * @package WordPress
 * @subpackage Twenty_Twelve
 * @since Twenty Twelve 1.0
 */

get_header(); ?>

	<div id="primary" class="site-content">
		<div id="content" role="main">

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

				<?php get_template_part( 'content', get_post_format() ); ?>

				<nav class="nav-single">
					<h3 class="assistive-text"><?php _e( 'Post navigation', 'twentytwelve' ); ?></h3>
					<span class="nav-previous"><?php previous_post_link( '%link', '<span class="meta-nav">' . _x( '←', 'Previous post link', 'twentytwelve' ) . '</span> %title' ); ?></span>
					<span class="nav-next"><?php next_post_link( '%link', '%title <span class="meta-nav">' . _x( '→', 'Next post link', 'twentytwelve' ) . '</span>' ); ?></span>
				</nav><!-- .nav-single -->

				<?php comments_template( '', true ); ?>

			<?php endwhile; // end of the loop. ?>

		</div><!-- #content -->
	</div><!-- #primary -->

<?php get_sidebar(); ?>
<?php get_footer(); ?>
