This should be a simple one but has had me puzzled for a few hours now.
On this site - http://topgearprestige.com.au/dev/
if you have a look at the 'cars' and 'contact' page, the top nav is sliding over to align with the content, rather than using the 100% width it has specified.
Bizarrely, this behavior isn't happening on the other two pages ('home' and 'location')
Also, the content is pushing itself up to the top of the page, rather than following the margin rules applied to it.
