Minimal Expanding Hamburger Menu With jQuery - Hamburger Nav

A jQuery based sticky hamburger menu where your users can click on the hamburger toggle button to reveal the site navigation with an expanding effect.

How to use it:

1. The html structure for the hamburger navigation.

<div class="navHeader">
  <header >
    <img src="threelines.png" alt="Hamburger" class="hamburger">
  </header>

  <div class="menu">
    <ul>
      <a href="" id="home">
        <li>Home</li>
      </a>
      <a href="" id="Section-1">
        <li>Section One</li>
      </a>
      <a href="" id="Section-2">
        <li>Section Two</li>
      </a>
      <a href="" id="Section-3">
        <li>Section Three</li>
      </a>
      <a href="" id="Section-4">
        <li>Section Four</li>
      </a>
      <a href="" id="Section-5">
        <li>Section Five</li>
      </a>
    </ul>
  </div>
</div>

2. The CSS to style the hamburger navigation and make it sticky at the top of the webpage.

header {
  width: 100%;
  background: #46CFB0;
  height: 50px;
  line-height: 50px;
}

.hamburger {
  background: none;
  position: absolute;
  top: 0;
  right: 0;
  line-height: 45px;
  padding: 12px 15px 0px 15px;
  color: ##ecf0f1;
  border: 0;
  font-size: 1.4em;
  font-weight: bold;
  cursor: pointer;
  outline: none;
}

.menu {
  z-index: 1000000;
  font-weight: bold;
  font-size: 0.8em;
  width: 100%;
  background: #FC6D58;
  color:#fff
  position: absolute;
  text-align: center;
}

.menu ul {
  margin: 0;
  padding: 0;
  list-style-type: none;
  list-style-image: none;
}

.menu li {
  display: block;
  padding: 15px 0 15px 0;
  color: #000;
  border-bottom: #fff 1px solid;
  font-size: x-large;
}

.menu li:hover {
  display: block;
  background: #E95546;
  padding: 15px 0 15px 0;
  border-bottom: #fff 1px solid;
}

.menu ul li a {
  text-decoration: none;
  margin: 0px;
  color: #fff;
}

.menu ul li a:hover {
  color: #fff;
  text-decoration: none;
}

.menu a {
  text-decoration: none;
  color: white;
}

.menu a:hover {
  text-decoration: none;
  color: white;
}

.sticky {
  position: fixed;
  width: 100%;
  left: 0;
  top: 0;
  z-index: 100;
  border-top: 0;
}

3. Include the latest version of jQuery library at the bottom of the webpage.

<script src="//code.jquery.com/jquery-1.12.0.min.js"></script>

4. The JavaScript.

var stickyNavTop = $('.navHeader').offset().top;

var stickyNav = function(){
var scrollTop = $(window).scrollTop();

if (scrollTop > stickyNavTop) {
    $('.navHeader').addClass('sticky');
} else {
    $('.navHeader').removeClass('sticky');
}
};

stickyNav();

$(window).scroll(function() {
    stickyNav();
});

function closeBurger() {
  $(".menu").slideToggle("slow", function() {
    $(".hamburger").show();
  });
};

$(".menu").hide();
$(".hamburger").click(function() {
  $(".menu").slideToggle("slow", function() {
    $(".hamburger").show();
  });
});
