Editing page to center ALL content?

So I am totally stumped by this – I am editing a page that came with a theme that shows calendar items on a single page. The first thing I did was remove the getsidebar code to make it “full width”, now what I want to do if possible is center the content. Here is the page code:

/*
Template Name: Full-Width Page Template
*/
<?php
/**
* The template for displaying the calendar page
*
*/

/**
Template Name: Calendar
*/

get_header(); ?>

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

<div class=”lastmess”>
<div class=”container”>
<div class=”grid10 first”>
<h1 class=”entry-title”><?php the_title(); ?></h1>
</div>
<div class=”grid2 dirr”>
<span><?php echo get_option(‘nets_sptdir’)?></span>
</div>
</div>
</div>
<div class=”bodymid”>
<div class=”stripetop”>
<div class=”stripebot”>
<div class=”container”>
<div class=”mapdiv”></div>
<div class=”clear”></div>
<div id=”main”>
<div class=”grid8 first”>
<div id=”content” role=”main”>
<div id=”post-<?php the_ID(); ?>” <?php post_class(); ?>>
<div class=”calmonth”>
<div class=”monthselect”>
“><?php _e( ‘PREV’, ‘wp_church’ ); ?>
<span>|</span> “><?php _e( ‘NEXT’, ‘wp_church’ ); ?>

</div>
<?php if(isset($_GET[‘month’]) || isset($_GET[‘year’])){ ?>
<h1><?php monthname($_GET[‘month’],$_GET[‘year’]); ?></h1>
<?php } else { ?>
<h1><?php monthname(”,”); ?></h1>
<?php } ?>

</div>
<?php if(isset($_GET[‘month’]) || isset($_GET[‘year’])){ ?>
<div class=”calentries”><?php get_the_calendar($_GET[‘month’],$_GET[‘year’]); ?></div>
<?php } else { ?>
<div class=”calentries”><?php get_the_calendar(date(‘n’),date(‘Y’)); ?></div>
<?php } ?>

<div class=”entry-content”>
<?php the_content(); ?>

</div><!– .entry-content –>
</div><!– #post-## –>
<?php endwhile; ?>
</div>
</div>

<?php get_footer(); ?>

Any ideas??

Thanks!
