function ScrollToResolver(elem) {
  var jump = parseInt(elem.getBoundingClientRect().top * .2);
  document.body.scrollTop += jump;
  document.documentElement.scrollTop += jump;
  if (!elem.lastjump || elem.lastjump > Math.abs(jump)) {
    elem.lastjump = Math.abs(jump);
    setTimeout(function() { ScrollToResolver(elem);}, "100");
