Fixed Header

Hello, I have created myself an extra header. I use the following code for tgis Widget Area

<div class="container_wrap_header-widget"><div class="container">
<div id="header-top" class="secondary">
<div id="Top-Header-1"><?php dynamic_sidebar( 'Top-Header-1' );?>
</div>
<div id="Top-Header-2"><?php dynamic_sidebar( 'Top-Header-2' );?>
</div><div id="Top-Header-3"><?php dynamic_sidebar( 'Top-Header-3' );
?></div></div>
</div></div>

Now my problem. I use the boxed layout with fixed header. Unfortunately I do not get it out, which is also fixed up the new Widget Area. Can you help me please.

Regards
