    #uses document because document will be topmost level in bubbling
    $(document).on "touchmove", (e) ->
      e.preventDefault()


    #uses body because jquery on events are called off of the element they are
    #added to, so bubbling would not work if we used document instead.
    $("body").on "touchstart", ".mobile-scrolling", (e) ->
      if e.currentTarget.scrollTop is 0
        e.currentTarget.scrollTop = 1
      else e.currentTarget.scrollTop -= 1  if e.currentTarget.scrollHeight is e.currentTarget.scrollTop + e.currentTarget.offsetHeight


    #prevents preventDefault from being called on document if it sees a scrollable div
    $("body").on "touchmove", ".mobile-scrolling", (e) ->
      e.stopPropagation()
