Trying to Style wp_list_pages

First, apologies if this has been posted elsewhere. Did a quick search for "style wp_list_pages" and found no relevant posts.

I am running WP 3.2.1 with BP 1.2.9. I have many plugins installed (mostly from WPMU Dev) but I don't think a plugin would have an effect on my current issue. (If a list of active plugins is needed, I will provide it.)

I'm not aware of a way to use archive.php to list only a specific category of pages so I have created a template to display the children of a certain page with the following code:

<?php
/*Template Name: Newsletter Archive Template*/
?>

<?php get_header(); ?>
<div id="container">
	<div id="content" role="main">

		<?php the_post(); ?>
		<h1 class="entry-title"><?php the_title(); ?></h1>

		<ul>
			<?php wp_list_pages('child_of=1357'); ?>
		</ul>

	</div><!-- #content -->
</div><!-- #container -->

<?php get_sidebar(); ?>

<?php get_footer(); ?>

The page works great: http://uniimi.com/newsletters/ however, everything is a lot smaller then on my regular pages and I can't figure out why.

Anyone know what I'm doing wrong?

Thanks!
