A hamburger style navigation button that morphs into a full width, responsive menu panel when toggled, built using jQuery, CSS, and CSS3 transitions.

How to use it:

1. Create the Html for the burger button & navigation menu.

<div class="burger">
  <span class="line"></span>
  <span class="line"></span>
  <span class="line"></span>
  <nav>
    <ul>
      <li>Home</li>
      <li>About</li>
      <li>Blog</li>
      <li>Contact</li>
    </ul>
  </nav>
</div>

2. The CSS styles for the hamburger button.

.burger {
  position: relative;
  margin-top: 20px;
  display: inline-block;
  width: 50px;
  height: 35px;
  background-color: rgba(0, 0, 0, 0.1);
  border-top: 1px solid rgba(0, 0, 0, 0.1);
  border-left: 1px solid rgba(0, 0, 0, 0.1);
  border-radius: 15px;
  padding: 4px 0;
  -webkit-transition: all 200ms cubic-bezier(0.455, 0.03, 0.515, 0.955);
  -moz-transition: all 200ms cubic-bezier(0.455, 0.03, 0.515, 0.955);
  -o-transition: all 200ms cubic-bezier(0.455, 0.03, 0.515, 0.955);
  transition: all 200ms cubic-bezier(0.455, 0.03, 0.515, 0.955);
}

.burger:hover { background-color: #5289c6; }

.line {
  display: block;
  position: absolute;
  height: 6px;
  width: 30px;
  left: 50%;
  top: 8px;
  margin-left: -15px;
  border-radius: 10px;
  box-sizing: content-box;
  -webkit-box-shadow: 1px 1px 0px 0px rgba(0, 0, 0, 0.15);
  -moz-box-shadow: 1px 1px 0px 0px rgba(0, 0, 0, 0.15);
  box-shadow: 1px 1px 0px 0px rgba(0, 0, 0, 0.15);
  background-color: #eee;
  -webkit-transition: all 200ms cubic-bezier(0.455, 0.03, 0.515, 0.955);
  -moz-transition: all 200ms cubic-bezier(0.455, 0.03, 0.515, 0.955);
  -o-transition: all 200ms cubic-bezier(0.455, 0.03, 0.515, 0.955);
  transition: all 200ms cubic-bezier(0.455, 0.03, 0.515, 0.955);
}

.line:nth-child(2) { top: 18px; }

.line:nth-child(3) { top: 28px; }

3. Style the navigation menu.

nav {
  display: none;
  text-align: center;
  position: absolute;
  width: 100%;
  bottom: 35px;
}

ul {
  font-size: 1.1em;
  font-family: 'Roboto Condensed', sans-serif;
  list-style-type: none;
  text-transform: uppercase;
  letter-spacing: 2px;
  margin: 0;
  padding: 0;
}

ul li {
  color: white;
  display: inline-block;
  margin: 0 20px;
  -webkit-transition: all 200ms ease;
  -moz-transition: all 200ms ease;
  -o-transition: all 200ms ease;
  transition: all 200ms ease;
}

ul li:hover {
  cursor: pointer;
  color: #ccdff4;
}

4. Create the morphing effect using CSS & CSS3 transitions.

.burger.expand {
  margin-top: 0;
  padding: 24px 0 100px;
  width: 100%;
  border-radius: 0;
  background-color: #5289c6;
}

.expand .line {
  width: 40px;
  margin-left: -20px;
}

.expand .line:first-child {
  -ms-transform: rotate(45deg);
  -webkit-transform: rotate(45deg);
  transform: rotate(45deg);
  top: 40px;
}

.expand .line:nth-child(3) {
  -ms-transform: rotate(-45deg);
  -webkit-transform: rotate(-45deg);
  transform: rotate(-45deg);
  -webkit-box-shadow: -1px 0px 0px 0px rgba(0, 0, 0, 0.15);
  -moz-box-shadow: -1px 0px 0px 0px rgba(0, 0, 0, 0.15);
  box-shadow: -1px 0px 0px 0px rgba(0, 0, 0, 0.15);
  top: 40px;
}

.expand .line:nth-child(2) {
  opacity: 0;
  top: 40px;
}

5. A little bit JavaScript to enable the morphing navigation. Add the following script after jQuery library and done.

$('.burger').on('click', function(){
  if( $(this).is('.expand')){
    $('nav').fadeOut('fast');
    $(this).delay(100).queue(function(){
      $(this).removeClass('expand').dequeue();
    });
  } else{
    $(this).delay(100).queue(function(){
      $(this).addClass('expand').dequeue();
    });
    $('nav').delay(200).fadeIn('fast');
  }
});
