There’s no adsense on the site you mentioned,
but I guess you want to add the adsense like the yellow box from the screenshot (the ad size is 468 x 60).

To do this, open header.php and on line 102, find the code below:
<?php
// Has the text been hidden?
if ( 'blank' == get_header_textcolor() ) :
?>
<div class="only-search<?php if ( ! empty( $header_image ) ) : ?> with-image<?php endif; ?>">
<?php get_search_form(); ?>
</div>
<?php
else :
?>
<?php get_search_form(); ?>
<?php endif; ?>
Comment out the search function and add top-adsense div box.
So it will look something like:
<div id="top-adsense">
<!-- adsense code goes here -->
</div>
<?php
// Has the text been hidden?
if ( 'blank' == get_header_textcolor() ) :
?>
<div class="only-search<?php if ( ! empty( $header_image ) ) : ?> with-image<?php endif; ?>">
<?php //get_search_form(); ?>
</div>
<?php
else :
?>
<?php //get_search_form(); ?>
<?php endif; ?>
Open style.css and add the css code:
#top-adsense {
width:468px;
height:60px;
position:absolute;
right:3.6%;
top: 3.5em;
}
Let me know if it works ok ??
