I've been reviewing a page for cross-browser compatibility though I've noticed a problem in the latest version of Firefox.
An unexplainable white block appears beneath the navigation menu though it does not occur in any other browser.
I've checked the CSS though I can't any specific CSS code that's causing the space i.e. no margins or paddings are specified.
Here's the page in question: http://tinyurl.com/cuq4ql2
Any insight would be appreciated.
