subpagimas ander uiterlijk geven

Ik gebruik thema wp_yoghurt op mijn site Vrijlance Die heeft eem mooi zijmenu (dat er beter uitziet dan de pages-widget) maar toont alle pagina’s, ook de subpaginas op dezelfde manier. Ik zou graag via CSS de subpagina’s een simpele indent willen geven maar het lijkt alsof er geen code is voor subpages en dus ook geen aparte css mogelijk. Dit is sidebar.php

<div id="sidebar">

<ul>
	<li id="sb_top">
		<div class="sb_logo">
	    	<a href="<?php bloginfo('url'); ?>" title="<?php bloginfo('name'); ?>">
	        <!-- The logo - Change it to be your own -->
	        <img src="<?php bloginfo('template_url'); ?>/images/logo.jpg" alt="Home" />
	        <!-- ...or you can remove the logo and add the line below -->
	        <!-- <a href="<?php bloginfo('url'); ?>" title="<?php bloginfo('name'); ?>"><?php bloginfo('name'); ?></a>  -->

	        <!-- ... and now the slogan: -->
	        <br />

	        </a>
	    </div>
	</li>

    <!-- Navigation -->
	<li>
	    <ul class="navlist">
	    	<?php wp_list_pages('sort_column=menu_order&title_li='); ?>
	        <!-- More info at http://codex.wordpress.org/Pages -->
	        <!-- ... and you should read the readme.txt file -->
	    </ul>
    </li>

<!-- Start Widget-ready -->
<!-- If you use Widgets (control panel - > Presentation - > Widgets), the content below will be replaced by the widgets you add to your sidebar -->
<?php if ( !function_exists('dynamic_sidebar') || !dynamic_sidebar() ) : ?>

    <!-- Author -->
    <li class="widget"><h2><?php _e('Author'); ?></h2>
		<ul>
			<li>
				<!-- Change image location below -->
	            <img src="<?php bloginfo('template_url'); ?>/images/budha.jpg" alt="Photo Example" />
	            A little something about you, the author. Open sidebar.php in your favorite web editor to edit this text and image. Alternatively, you can simply go to <em>Dashboard -> Design -> Widgets</em> and add the '<b>Text</b>' widget to your sidebar to create your own bio. When you add a widget to the sidebar, this section and the ones below will be substituted by your widgets.
			</li>
		</ul>
	</li>

    <!-- Categories -->
	<li class="widget"><h2><?php _e('Categories'); ?></h2>
        <ul>
			<?php wp_list_cats('sort_column=name&optioncount=1&hierarchical=0'); ?>
		</ul>
	</li>

    <!-- Archives -->
	<li class="widget"><h2><?php _e('Archives'); ?></h2>
        <ul>
			<?php wp_get_archives('type=monthly'); ?>
		</ul>
	</li>

<?php endif; //function_exists('dynamic_sidebar') ?>

	<li class="widget"><h2><?php _e('Meta'); ?></h2>
		<ul>
			<?php wp_register(); ?>
			<li><?php wp_loginout(); ?></li>
			<li><a href="http://wordpress.org/" title="Powered by WordPress, state-of-the-art semantic personal publishing platform.">WordPress</a></li>                    

			<?php wp_meta(); ?>
		</ul>
	</li>
