scrolledIntoView.js

function scrolledIntoView(element) {
  var rect = element.getBoundingClientRect()
    , h = (window.innerHeight || document.documentElement.clientHeight)
    , w = (window.innerWidth || document.documentElement.clientWidth)
    , verticalVisibility = (rect.top <= h) && ((rect.top + rect.height) >= 0)
    , horizontalVisibility = (rect.left <= w) && ((rect.left + rect.width) >= 0)
  return verticalVisibility && horizontalVisibility
}

thanks for this, works perfectly! even in both mobile landscape and portrait views.
