Can't expand text over removed sidebar

I guess I don’t understand. It appears this way in every browser the text will not fill up the full single column container. Here is another example:

<?php get_header(); ?>
<div id="page-header">
	<h1><?php echo get_post_meta($post ->ID, 'short-title', true); ?></h1>
</div><!--end of page-header-->
<div id="content-container">
                  <div id="page-more-meat">
	<?php if (have_posts()) : while (have_posts()) : the_post(); ?>

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

			<h2 id="post-title"><?php the_title(); ?></h2>

			<?php /*?><?php include (TEMPLATEPATH . '/inc/meta.php' ); ?><?php */?>

			<div class="entry">

				<?php
					global $more;
					$more = 0;
				?>

				<?php the_content('Continue Reading'); ?>

			</div>
			<p style="float:left;"><a href="history.go(-1)">« Go back</a></p>
			<?php edit_post_link('Edit this entry','',''); ?>

		</div>

	<?php /*?><?php comments_template(); ?><?php */?>

	<?php endwhile; endif; ?>

	</div>
</div>
<?php get_footer(); ?>

Am I missing something I don’t see anything like that in my css:

[Excessive CSS moderated. A link to your site is all that is needed]

I installed firebug and looking at the CSS in firefox I still don’t see anything referring to the width you have above “678px” or the padding of “30px” that is not in my CSS file anywhere. What am I missing? Only thing close is the following: #page-wrap { width: 960px; margin: 20px auto; }
