urbanrich on "Move header widget area to right side"

I have added a widget area to my header by following a tutorial found here

http://stackoverflow.com/questions/15497201/how-to-add-widget-to-the-header-php-in-wordpress

This works fine, but I'm trying to find out if and how it's possible to move the widget area to the right of the page, as at the moment the widget I'm using in the header is centered. I don't really know coding, but I'm presuming that the widget is being aligned to the center due to where the widget area is, and not the widget itself, because looking at screenshots of the widget, it should be positioned to the right of the page.

I'd really appreciate any help with this. Thanks.
