unnecessary white space in chrome

Hello Omeka Team,

Any idea as to why I have an extra white space between my header and navigation in Google Chrome?

In every other browser, this gap appears to be closed. I have tried to inspect the element several times with no luck. I am by no means a web design expert, so perhaps I am missing something obvious within the HTML or CSS.

Thanks for any help you can provide,

Will

When I turned off the margin-right property on div#primary-nav in the inspector, it seems to go away

That worked great, Patrick! Thank you for the quick response.
