Scrolling 100vh sections on mouse scroll

Looking to the javascript of the example, we can see that the page works with all the elements, one after the another, but when he puts the command overflow:hidden; the page not shows the scroll bar.

To give the effect for all the pages, there is an effect "translate3d" and the page "scrolls". To show the second page:

transform: translate3d(0px, -622px, 0px);

For the third:

transform: translate3d(0px, -1244px, 0px);

I dont found the command into the page to get the mouse wheel, but you can put a event that will be fired when you scroll the page.

$("body").bind("mousewheel", function(e)
{
    var delta = e.originalEvent.wheelDelta; // give you the direction
    // here you apply the transform on the page.
});

I'm not sure if this example page is using any framework, but i found this question that can help you, if you dont want to do from the beginning. The library mencioned at this question is the same as Michael Coker commentary (alvarotrigo.com/fullPage).

scroll a full page height up or down with jQuery/Javascript

I know that the response is not complete, but can give you some directions.
