Navigational highlighting of current page section on a one-page website

I'm struggling with adding a navigation bar feature that will highlight the current section being viewed on my website. All I want is for the currently viewed section to appear bold in the navigation bar.

Check out the codepen link:

HTML

  <nav id="nav-wrap">
    <ul>
      <li class="current"><a class="page" href="#home">Home</a></li>
      <li><a class="page" href="#about">About</a></li>
      <li><a class="page" href="#portfolio">Portfolio</a></li>
      <li><a class="page" href="#scrapbook">Scrapbook</a></li>
      <li><a class="page" href="#contact">Contact</a></li>
    </ul>
  </nav>

  <div class="header-content">
    <img id="logo" src="img/logo.png" alt="logo" height="200px" width="200px">
    <h3>Joseph Cooper</h3>
    <h3>Graphic Designer</h3>
    <p> 10.03.97 </p>
  </div>

<a href="#about"><img id ="down" src="img/down.png" height="42px" width="42px"></a>

Answer №1

After some modifications, I managed to adjust the formatting of the navigation links on my webpage. One line of code was added to remove the bold style from all href elements in the navigation, while another line was included to apply bold styling to the href that is clicked. You can see the updated code on CodePen: http://codepen.io/anon/pen/doaRjy

function smoothScroll(duration) {
    $('a[href^="#"]').on('click', function(event) {        
        var target = $( $(this).attr('href') );

        $("#nav-wrap a").css('font-weight','normal')/*this line removes bold from all href*/
        $(this).css('font-weight','bold')/*this line adds bold to clicked href*/

        if(target.length) {
            event.preventDefault();
            $('html, body').animate({
                scrollTop: target.offset().top
            }, duration);
        }
    });
}

Answer №2

I attempted to resolve this issue by utilizing jQuery's offset().top method and comparing it with the window's scrollTop value.

var $window = $(window),
  homeLink = $("a[href='#home']"),
  aboutLink = $("a[href='#about']"),
  portfolioLink = $("a[href='#portfolio']");

$window.on("scroll", function(e) {

  if ($window.scrollTop() < $("#about").offset().top) {

    $("#nav-wrap").find("a").css("font-weight", 400);
    homeLink.css("font-weight", 900);

  } else if ($window.scrollTop() > $("#about").offset().top && $window.scrollTop() < $("#portfolio").offset().top) {

    $("#nav-wrap").find("a").css("font-weight", 400);
    aboutLink.css("font-weight", 900);

  }

});
