function autoScroll(name, animated, distance){
     var scrollDistance = distance;
     var scrollTarget = $("*[name='"+name+"']");

     if(animated){
         $('html, body').animate({scrollTop: (scrollTarget.offset().top - scrollDistance)}, 1300);
     }
     else{
         $('html, body').scrollTop(scrollTarget.offset().top - scrollDistance);
     }
 }

 //Stop default hashtag scrolling
 window.scrollTo(0, 0);

 //Execute stuff when entire page is loaded
 $(window).bind("load", function() {

     //Check if there is a hashtag in URL
     if(window.location.hash) {
         //Get hashtag in URL
         var getHash = window.location.hash.substring(1);
         //Do the scroll function to the desired section
         autoScroll(getHash,true,0);
     }

     //Do it manually
     autoScroll("backtolist",true,0);
 });
