    Parallax Scrolling Issues

    Hi,

    I'm new to coding, I'm currently designing myself a portfolio website to showcase my design skills, I've developed a problem I hope you could help me out with!

    I've built a skeleton for a parallax scrolling index page with the idea to then link to individual projects from the portfolio section. I've spent a while on the visuals and had the scrolling working but now when I've tried to make the site responsive (using media queries to load different CSS styles) it seems to mess up now when it scrolls down to the correct section it then jumps somewhere else.

    Would you be able to look at my code and tell me if there is something I am doing horribly wrong? My website is online at Matt Wilson Graphic Designs

    I'll also upload the code here too.

    HTML

    PHP Code:
    <!doctype html>
    <    html>
    <    head>

      return     string
            .replace(/^\//,'')

      $(    'a[href*=#]').each(function() {
        var     thisPath = filterPath(this.pathname) || locationPath;
        if (      locationPath == thisPath
            && (location.hostname == this.hostname || !this.hostname)
        &&     this.hash.replace(/#/,'') ) {
              var $target = $(this.hash), target = this.hash;
          if (    target) {
            var     targetOffset = $target.offset().top;
            $(    this).click(function(event) {
                  event.preventDefault();
              $(    scrollElem).animate({scrollTop: targetOffset}, 1000, function() {
                    location.hash = target;
              });
            });
          }
        }
      });
     
          // use the first element that is "scrollable"
          function scrollableElement(els) {
        for (var     i = 0, argLength = arguments.length; i <argLength; i++) {
          var     el = arguments[i],
                  $scrollElement = $(el);
          if (    $scrollElement.scrollTop()> 0) {
            return     el;
          } else {
                $scrollElement.scrollTop(1);
            var     isScrollable = $scrollElement.scrollTop()> 0;
                $scrollElement.scrollTop(0);
            if (    isScrollable) {
              return     el;
            }
          }
        }
        return [];
      }
     
    }); 
    If you understand where I've gone wrong I would really appreciate some feedback!

    Best wishes
