When you click on the nav on mobile (iOS) and choose a menu item like Portfolio or Team, it doesn’t scroll down to the appropriate container section. It works on web, not mobile.
iPhone 6S Safari works great as well as OS X iOS 9.2 iPhone 6S simulator. Tho one thing… I wasn’t able to touch-scroll from hero section making it extremely difficult to navigate throughout the page. I like the effect in the background, but that shouldn’t interfere with the overall UX.
