and page layout

so im working locally on a wordpress site and came into a problem, all the other pages use the section tag which i styled to be a full width page, however my blog page i want to have sidebars.

there is no section tag in the loop.php file, tried making a new template called blog.php and copying the loop info into it, while i can set the blog page to the new template none of the changes save so i started just editing the loop.php file which seems to work.

now the problem is there is no section tag there but it still uses it from what i can see, i was able to resize the blog content by adding a div with a smaller width but it still appears in the section tag and the sidebar no matter where i move it will not sit correctly.

here is the loop code:

<div class="grid9">		<!-- 1/3 column start -->

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

	<!-- article -->
	<article id="post-<?php the_ID(); ?>" <?php post_class(); ?>>

		<!-- post thumbnail -->
		<?php if ( has_post_thumbnail()) : // Check if thumbnail exists ?>
			<a href="<?php the_permalink(); ?>" title="<?php the_title(); ?>">
				<?php the_post_thumbnail(array(120,120)); // Declare pixel size you need inside the array ?>
			</a>
		<?php endif; ?>
		<!-- /post thumbnail -->

		<!-- post title -->
		<h2>
			<a href="<?php the_permalink(); ?>" title="<?php the_title(); ?>"><?php the_title(); ?></a>
		</h2>
		<!-- /post title -->

		<!-- post details -->
		<span class="date"><?php the_time('F j, Y'); ?> <?php the_time('g:i a'); ?></span>
		<span class="author"><?php _e( 'Published by', 'html5blank' ); ?> <?php the_author_posts_link(); ?></span>
		<span class="comments"><?php comments_popup_link( __( 'Leave your thoughts', 'html5blank' ), __( '1 Comment', 'html5blank' ), __( '% Comments', 'html5blank' )); ?></span>
		<!-- /post details -->

		<?php html5wp_excerpt('html5wp_index'); // Build your custom callback length in functions.php ?>

		<?php edit_post_link(); ?>

	</article>
	<!-- /article -->

<?php endwhile; ?>

<?php else: ?>

	<!-- article -->
	<article>
		<h2><?php _e( 'Sorry, nothing to display.', 'html5blank' ); ?></h2>
	</article>
	<!-- /article -->

	</div><!-- 1/3 column end -->
<?php get_sidebar(); ?>

<?php endif; ?>

<div class="clear"></div>
<div class="spacerfooter"></div>

css for the grid is:

.grid9 {
	width: 726px;
}

section{
	background-color:#FFF;
	width:1200px;
	margin:0 auto;
	box-shadow:0px 4px 6px -4px #333;
	padding:5px;
	border:1px solid #000;
	margin-top:20px;
	margin-bottom:250px;
	padding-left:15px;
	padding-right:15px;
}

is there a way to get the sidebar into the section or a way to make a separate section for this page?

thanks
