Modern Overlay Side Navigation With jQuery And CSS3 - Techie Menu

A modern, translucent, semantic, multi-level, off-canvas navigation with a hamburger toggle button that covers part of the page when toggled.

Built using jQuery, HTML unordered list, and CSS3 transitions & transforms.

How to use it:

1. Create the HTML for the overlay navigation.

<div class="navigation">
  <div class="toggle-wrapper">
    <span class="show">&#9776;</span>
    <span class="hide">&#9866;</span>
  </div>
  <div class="heading">Site Logo</div>
  <ul class="menu">
    <li><a href="#!">Home</a></li>
    <li class="active"><a href="#!">Blog</a></li>
    <li class="has-menu">
      <a href="#!">Category</a>
      <ul class="menu">
        <li><a href="#!">jQuery</a></li>
        <li><a href="#!">HTML5</a></li>
        <li><a href="#!">CSS/CSS3</a></li>
      </ul>
    </li>
    <li><a href="#!">Contact</a></li>
    <li><a href="#!">About</a></li>
  </ul>
</div>

2. The necessary CSS/CSS3 styles.

.navigation {
  border: 1px solid rgba(255,255,255,0.1);
  height: 100%;
  width: 320px;
  background-color: rgba(255,255,255,0.1);
  color: #fff;
  position: fixed;
  z-index: 9999;
  top: 0;
  right: calc(100% - 320px);
  transition: right 0.5s;
}

.navigation .heading {
  padding: 15px;
  height: 51px;
  border-bottom: 1px solid rgba(255,255,255,.1);
  line-height: 20px;
}

.navigation .menu {
  list-style-type: none;
}

.navigation .menu li {
  border-bottom: 1px solid rgba(255,255,255,0.1);
}

.navigation .menu a {
  display: block;
  padding: 15px;
  line-height: 20px;
  color: #fff;
  text-decoration: none;
  position: relative;
  z-index: 0;
}

.navigation .menu a::after {
  content: '';
  background-color: rgba(255,255,255,0.1);
  position: absolute;
  top: 0;
  right: 100%;
  bottom: 0;
  left: 0;
  transition: left 0.25s, right 0.25s;
}

.navigation .menu a:hover::after {
  right: 0;
}

.navigation .has-menu {
  position: relative;
}

.navigation .has-menu::before {
  content: '';
  border-left: 1px solid rgba(255,255,255,0.1);
  height: 50px;
  width: 50px;
  cursor: pointer;
  position: absolute;
  top: 0;
  right: 0;
  z-index: 1;
}

.navigation .has-menu::after {
  content: '\027A4';
  padding: 15px 0;
  height: 50px;
  width: 50px;
  line-height: 20px;
  text-align: center;
  cursor: pointer;
  position: absolute;
  top: 0;
  right: 0;
  z-index: 1;
  transform: rotate(90deg);
  transition: transform 0.25s;
}

.navigation .has-menu > .menu {
  overflow: hidden;
  max-height: auto;
}

.navigation .menu .menu {
  border-top: 1px solid rgba(255,255,255,0.1);
}

.navigation .has-menu > .menu > li > a {
  padding-left: 45px;
  transition: padding 1s;
}

.navigation .has-menu > .menu > li:last-child {
  border-bottom: none;
}

/* Closed States */
.navigation:not(.open) {
  right: 100%;
}

.navigation:not(.open) .toggle-wrapper .show {
  right: 0px;
}

.navigation:not(.open) .toggle-wrapper .hide {
  right: 50px;
}

.navigation .has-menu:not(.open)::after {
  transform: rotate(-90deg);
}

.navigation .has-menu:not(.open) > .menu {
  border-top: none;
  max-height: 0;
}

.navigation .has-menu:not(.open) > .menu > li > a {
  padding-left: 15px;
}

3. The CSS rules for the hamburger toggle button.

.navigation .toggle-wrapper {
  border: 1px solid rgba(255,255,255,0.1);
  border-left: none;
  height: 52px;
  width: 51px;
  background-color: rgba(255,255,255,0.1);
  overflow: hidden;
  position: absolute;
  top: -1px;
  right: calc(0px - 52px);
}

.navigation .toggle-wrapper span {
  width: 50px;
  height: 50px;
  line-height: 50px;
  text-align: center;
  background-color: transparent;
  color: inherit;
  cursor: pointer;
  position: absolute;
  top: 0;
  right: 0;
  transition: right 0.25s;
}

.navigation .toggle-wrapper .show {
  right: -50px;
}

4. Include the required jQuery library at the bottom of the webpage.

<script src="https://code.jquery.com/jquery-3.3.1.slim.min.js" integrity="sha384-q8i/X+965DzO0rT7abK41JStQIAqVgRVzpbzo5smXKp4YfRvH+8abtTE1Pi6jizo" crossorigin="anonymous"></script>

5. The main JavaScript (jQuery script) to toggle CSS classes based on the current state of the navigation.

$(function(){

  $('.navigation .toggle-wrapper .show').on('click',function(){
    $('.navigation').addClass('open');
  });
  $('.navigation .toggle-wrapper .hide').on('click',function(){
    $('.navigation').removeClass('open');
  });
  $('.navigation .has-menu a').on('click',function(e){
    e.stopPropagation();
  });
  $('.navigation .has-menu').on('click',function(){
    $(this).toggleClass('open');
  });
  
});
