a slightly more complete version of the Michael Whinfrey's answer , a pure JavaScript solution, which will make the the jump to anchor on every page load ( aka also when landing from another page ) ...

function scrollTo(name) {
  scrollToResolver(document.getElementById(name));
}

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);}, "20");
  } else {
    elem.lastjump = null;
  }
}

window.onload = function WindowLoad(event) {
   var uri = window.location.href
   var anchor = ( uri.indexOf('#') === -1 ) ? '' : uri.split('#')[1]
   if ( anchor != '' ) { window.location.hash = anchor }
   scrollTo(anchor)
}
