listing page style

hi I have following code on my Page template to list out subpage on a parent page. That code lists all the pages on one column list, so my question is how to list all pages on two column list.

==========================================
<?php
/*
Template Name: Bios
*/
?>

<?php get_header(); ?>
<!– Container –>
<div class=”CON”>

<!– Start SCS –>
<div class=”SCS”>
<?php include (TEMPLATEPATH . “/menu.php”); ?>

<?php if (have_posts()) : ?>
<?php while (have_posts()) : the_post(); ?>
<h1><?php the_title(); ?></h1>
<p><?php wp_list_pages(‘child_of=1267&title_li=&sort_column=post_name’); ?></p>

<?php the_content(“<p>__(‘Read the rest of this page »’)</p>”); ?>

<?php edit_post_link(__(‘Edit’), ‘<p>’, ‘</p>’); ?>
<?php endwhile; endif; ?>
</div>
<!– End SC –>
<?php get_sidebar(); ?>

<!– Container –>
</div>

<?php get_footer(); ?>
