Spun Theme Header Size

Hi There.

I am creating a super basic site here. I am using the WordPress option for Bluehost.

This is seriously just the smallest issue, so I don’t think a child theme is all that necessary, and might be a tad outside my understanding.

All I need to do is remove the restrictions on the Spun theme’s header size. My code knowledge is minimal, but I have monkeyed with the code enough to adjust transparencies, etc.

Is there something simple in the style sheet I can adjust so I can have a larger header on my page?

Thanks,
Mark
