Editing the Header Widget

Hi All!
I was able to successfully add a header widget using the WP Custom Widget Area plugin; however, the widget appears on the left side and extends all the way across the header. I would like this widget to appear on the upper right side across my logo and to not extend all the way across the header.
I added the code into the header.php and the code that I added was: dynamic_sidebar( ‘header-widget’ );
How do I change the appearance and location of this widget?
It’s been a nightmare trying to change this; please help!!
