New custom template issue!

Hi I am using a twenty eleven child theme and I am trying to create a new template. I follow everything describes here but the result I get is bad. The title and the sidebar is appear too low in the page.
Take a look at this image.

The code I use is:

<?php
/**
 * Template Name: example
 *
 * Selectable from a dropdown menu on the edit page screen.
 */
?>

<?php get_header(); ?>

		<div id="primary">
			<div id="content">
                                <?php the_post(); ?>
                                <?php get_template_part( 'content', 'main' ); ?>

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

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

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

Please I need some advice, thanks in advance!!!
