post title not showing

my post will show up but not the post title
here is my code:

<?php get_header(); ?>
  <div id="content">
  <div id="main">
   <?php if (have_posts()) : ?>

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

			<div <?php post_class() ?> id="post-<?php the_ID(); ?>">
                                <div id="poststyle">
				<h2 class="post"><?php the_title(); ?></h2>

				<div class="entry">
					<?php the_content('Read the rest of this entry &raquo;'); ?>
				</div>

			<!--<p class="postmetadata"><?php the_tags('Tags: ', ', ', '<br />'); ?> Posted in <?php the_category(', ') ?> | <?php edit_post_link('Edit', '', ' | '); ?>  <?php comments_popup_link('No Comments »', '1 Comment »', '% Comments »'); ?></p>-->
			</div>
</div><!-- end poststyle -->
		<?php endwhile; ?>

		<div class="navigation">
			<div class="alignleft"><?php next_posts_link('&laquo; Older Entries') ?></div>
			<div class="alignright"><?php previous_posts_link('Newer Entries &raquo;') ?></div>
		</div>

	<?php else : ?>

		<h2 class="center">Not Found</h2>
		<p class="center">Sorry, but you are looking for something that isn't here.</p>
		<?php get_search_form(); ?>

	<?php endif; ?>
  </div><!-- end main -->

  <div id="sidebar">
<?php get_sidebar(); ?>
  </div><!-- end sidebar -->
</div><!-- END CONTENT -->
<?php get_footer(); ?>

the css

h2.post {font-size:15px; text-align:left; margin-left:3px;border-bottom:1px solid #c0c0c0}
h3 {font-size:14px;border-bottom:1px solid black; width:631px; text-align:right}
h6 {font-size:10px;margin:0px;padding:0px; font-weight:normal;display:inline;line-height:10px}

.sidebarList {text-align:left; margin-left:-10px}

#poststyle {}
.entry {margin-left:10px;}

I have tried in both IE8 and chrome, nothing! Thanks for the help!
