WordPress Query Posts To Show All & Style Each One - wordpress

Question

I am trying to include every post onto my index page on WordPress and have each one of them be styled with the included CSS. I am able to query all of the posts and have them show up, but only the first post is actually styled. The rest inherit the base h1, h2, p and other generic styles, but they aren't inheriting the "box" class for each one. All of the information is being thrown into one 'box' class instead of starting a new 'box' class for each post like I would like it to do. Any help on this would be appreciated.
Here is my code I am using
<?php get_header(); ?>
<div id="index-float-left">
<div class="box">
<?php query_posts( 'showposts=-1' ); ?>
<?php if (have_posts()) : while (have_posts()) : the_post(); ?>
<div <?php post_class() ?> id="post-<?php the_ID(); ?>">
<h1><?php the_title(); ?></h1>
<p><?php the_content(); ?></p>
<p class="post-date"><?php echo $post_date = get_the_date(); ?></p>
</div>
</div> <!-- END BOX -->
</div> <!-- FLOAT BOX BOX -->
<?php endwhile; ?>
<?php else : ?>
<h2>Not Found</h2>
<?php endif; ?>
<?php get_sidebar(); ?>
<?php get_footer(); ?>

There is a problem with "End Box" and "Fload Box Box". Can you try like this:
<?php get_header(); ?>
<div id="index-float-left">
<?php query_posts( 'showposts=-1' ); ?>
<?php if (have_posts()) : while (have_posts()) : the_post(); ?>
<div class="box">
<div <?php post_class() ?> id="post-<?php the_ID(); ?>">
<h1><?php the_title(); ?></h1>
<p><?php the_content(); ?></p>
<p class="post-date"><?php echo $post_date = get_the_date(); ?></p>
</div>
</div> <!-- END BOX -->
<?php endwhile; ?>
<?php else : ?>
<h2>Not Found</h2>
<?php endif; ?>
</div> <!-- FLOAT BOX BOX -->
<?php get_sidebar(); ?>
