'How do I link to top of a section on the page minus the height of a fixed nav-bar?

When I click a link on my fixed navigation bar, it jumps to a specific section on the page, but the fixed nav-bar's height spills over. How can I subtract that height? Will this require javascript/jquery?

<div id="fixedNavWrapper">
    <div id="navLinks">
        <ul>
            <li><a href="#about">ABOUT ME</a></li>
            <li><a href="#portfolio">PORTFOLIO</a></li>
        </ul>
    </div>
</div>

<section id="about" class="section">
    <h2>ABOUT ME</h2>
</section>

.CSS:

#fixedNavWrapper {
  position: fixed;
  z-index: 1;
  width: 100%;
  top: 0;
  left: 0;
}

#navLinks {
  text-align: center;
  width: 100%;
  height: 57px;
  background: #000000;
}

#navLinks ul {
  list-style: none;
  margin: 0;
  padding: 5px;
  display: inline-block;
} 

#navLinks ul li {
  margin: 0;
  padding: 0;
  display: inline;
}

#navLinks ul li a {
  text-decoration: none;
  display: block;
  float: left;
  padding: 0 65px;
  height: 45px;
  line-height: 45px;
}

a bit more general:

$('.navbar li a').click(function () {

    var speed = 500;
    var easing = 'swing';
    var topMargin = 10;

    var href = $(this).attr("href");
    var name = href.substr(href.indexOf("#") + 1);
    var $link = $("a[name='" + name + "']");

    positionabout = $link.offset().top - $('.navbar').height() - topMargin;
    $("html, body").animate({scrollTop: positionabout}, speed, easing);

    return false;
});

just add this to your .css file:

html {scroll-padding-top: 5rem;}
