Trying to move text down a bit

I am using wordpress 2.9 and the default Kubrick theme. I am trying to get the . . . . . . . . moved down near the bottom part of my red logo. I know it is css that I need but I cannot seem to figure out if I have it in the right place or not and what the other stuff I need in my style.css file.

In my header file I added the following code:

<div class="ad-top">
. . . . . . . . .
</div>

Below is the section I added it in my header.php file:

<div id="page">

<div id="header">
	<div id="headerimg">
		<h1><a href="<?php echo get_option('home'); ?>/"><?php bloginfo('name'); ?></a></h1>
		<div class="description"><?php bloginfo('description'); ?>
		      <div class="ad-top">
                      . . . . . . . . .
                      </div>
		</div>
	</div>
</div>
<hr />

In the very bottom of my style.css file I added:

.ad-top {
	text-align: center;
}

and I almost forgot, my website is: https://www.igotitonclearance.com
Any help would be greatly appreciated!
