Styling…

So I’m trying to use a flickr widget and the entire widget is in a
<li>.

If I take the widget php code out of the
<ul> that it’s in and put it in a <div>, it floats really far left.

Here’s my test site: https://www.ericdmunoz.com/test

Here’s my sidebar widget:

<ul>
<?php 	/* Widgetized sidebar, if you have the plugin installed. */
		if ( !function_exists('dynamic_sidebar') || !dynamic_sidebar() ) : ?>
	<?php wp_list_pages('title_li=' . __('Pages:')); ?>
	<?php wp_list_bookmarks('title_after=&title_before='); ?>
	<?php wp_list_categories('title_li=' . __('Categories:')); ?>
<?php endif; ?>
</ul>

Here’s a link to the plugin I’m using:

Is it possible to style my widget/plugin and/or change the natural
<li> that it’s in?
