I just started using your ad manager. It works perfectly for what I need. However, I'm having some alignment issues with the ad I've placed in the header. I translated the shortcode to php. Right now, it is hugging the logo of the site I'm building until I scroll down (it has a responsive header), then the ad centers itself. How can I get it to be center from the get-go?

It's the 'Potomac Eagle' ad.
