background color only shows in part of the footer

The background color only shows for text I type in the footer container. But the lists do not show a background color. How can I get the background color to show for the lists?

<link rel="stylesheet" type="text/css" media="all" href="<?php bloginfo( 'stylesheet_url' ); ?>" />
		<div id="footer">
If I type text here, it has a background. But the following lists
don't get a background.
	<div class="footer-item">
	<ul>
	<h2>Articles by Subject</h2>
	<?php wp_get_archives('type=postbypost&limit=4')?>
	</ul>
	</div>
	<div class="footer-item">
	<ul>
	<h2>Articles by Publication</h2>
	<?php wp_list_categories( 'style=none');?>
	</ul>
	</div>
	<div class="footer-item">
	<ul>
	<h2>Favorite Sites</h2>
	<?php wp_list_bookmarks('title_li=&categorize=0'); ?>
	</ul>
	</div>
		</div>
