How to style Wordpress Widgets?

Here's my situation, I'm creating a Wordpress theme that can be found here:

I'm using a page widget. I'm not having any problems styling the list items under the heading, but I can't seem to figure out how to style the heading which is also a list item. Anyone have a solution?

Thanks

 

style ul.widget or ul.widget_pages

 

Neither of those work.

This is the HTML that the widget is outputting:

<li id="pages-3" class="widget widget_pages"><h2>Services</h2>		<ul>
			<li class="page_item page-item-33"><a href="http://webpuffs.com/marktanner/services-2/landscaping">Landscaping</a></li>

<li class="page_item page-item-29"><a href="http://webpuffs.com/marktanner/services-2/lawn-care">Lawn Care</a></li>
<li class="page_item page-item-34"><a href="http://webpuffs.com/marktanner/services-2/snow-removal">Snow Removal</a></li>
		</ul>
		</li>

HTML:

 

whoops my bad...
It's supposed to be just

.widget

Code (markup):

.widget_pages 

Code (markup):

Not ul.widget or ul.widget_pages

 

Total Widget Control allows you to use widget wrappers saving time on styling widgets. Also its user interface is easier to use for placing widgets than WP's drag and drop setup.
