iOS does not support parallax scrolling.
The reason for this, is because parallax is too heavy on the graphics processor. iOS cannot handle it [YET].
thank you for your reply , ow wow thats a shame , I can see whats in store for the future then
so now I need to figure out a way for people visiting from an ios product to be linked to a different page
parallax works on iOS! - it just needs to have touch gestures, not mouse events
