Sticky headers suffer from one glaring issue: If the page loads to an #anchor position, the sticky header covers up the anchor. Fix:

  window.onload = function()
  {
   var titlebarfixcoverfunction = function()
   {
    if (location.hash.indexOf('#') > -1)
    {
     var titlebar = document.getElementById('title');
     window.scrollBy(0, -titlebar.offsetHeight);
    }
   };
   titlebarfixcoverfunction();
   window.addEventListener('hashchange', titlebarfixcoverfunction);
  }
