Responsive Off-canvas Sidebar Navigation With jQuery And CSS3

A jQuery/CSS3 based responsive, off-canvas navigation where the sidebar menu is displayed by sliding the entire page to the left (or right) side when toggled.

How to use it:

1. Create the sidebar navigation that is hidden on page load.

<div class="sidebar">
  <ul class="sidebar-list">
    <li class="sidebar-item">
      <a href="#" class="sidebar-anchor">Item 1</a>
    </li>
    <li class="sidebar-item">
      <a href="#" class="sidebar-anchor">Item 2</a>
    </li>
    <li class="sidebar-item">
      <a href="#" class="sidebar-anchor">Item 3</a>
    </li>
  </ul>
</div>

2. Create a button to toggle the sidebar navigation.

<div class="nav-right visible-xs">
  <div class="button" id="btn">
    <div class="bar top"></div>
    <div class="bar middle"></div>
    <div class="bar bottom"></div>
  </div>
</div>

3. Insert another hidden toggle button into the main content.

<main>
  <nav>
    <div class="nav-right hidden-xs">
      <div class="button" id="btn">
        <div class="bar top"></div>
        <div class="bar middle"></div>
        <div class="bar bottom"></div>
      </div>
    </div>
  </nav>
</main>

4. Insert another hidden toggle button into the main content.

main {
  z-index: 2;
  position: relative;
  height: 100%;
  background-color: #2D3142;
  -webkit-transition: transform .7s ease-in-out;
  -moz-transition: transform .7s ease-in-out;
  -ms-transition: transform .7s ease-in-out;
  -o-transition: transform .7s ease-in-out;

  position: fixed;
  top: 0;
  z-index: 1;
  right: 0;
  background-color: #EF8354;
}

.move-to-left {
  -webkit-transform: translateX(-400px);
  -moz-transform: translateX(-400px);
  -ms-transform: translateX(-400px);
  -o-transform: translateX(-400px);
  transform: translateX(-400px);

  margin: 0;
  list-style: none;
  position: relative;
  margin-top: 150px;

  -ms-transition: all .7s .2s ease-in-out;
  -o-transition: all .7s .2s ease-in-out;
  transition: all .7s .2s ease-in-out;
}

.sidebar-item:nth-child(2) {
  -webkit-transition: all .7s .4s ease-in-out;
  -moz-transition: all .7s .4s ease-in-out;
  -ms-transition: all .7s .4s ease-in-out;
  -o-transition: all .7s .4s ease-in-out;
  transition: all .7s .4s ease-in-out;
}

.sidebar-item:nth-child(3) {

  -moz-transition: all .7s .6s ease-in-out;
  -ms-transition: all .7s .6s ease-in-out;
  -o-transition: all .7s .6s ease-in-out;
  transition: all .7s .6s ease-in-out;
}

.sidebar-item:last-child {
  -webkit-transition: all .7s .8s ease-in-out;
  -moz-transition: all .7s .8s ease-in-out;
  -ms-transition: all .7s .8s ease-in-out;
  -o-transition: all .7s .8s ease-in-out;
  transition: all .7s .6s ease-in-out;
}

.sidebar-item.active {
  opacity: 1;
  -webkit-transform: translateY(0px);
  -moz-transform: translateY(0px);
  -ms-transform: translateY(0px);
  -o-transform: translateY(0px);
  transform: translateY(0px);
}

.sidebar-anchor {
  color: #FFF;
  text-decoration: none;
  font-size: 1.8em;
  text-transform: uppercase;
  position: relative;
  padding-bottom: 7px;
}

.sidebar-anchor:before {
  content: "";
  width: 0;
  height: 2px;
  position: absolute;
  bottom: 0;
  left: 0;
  background-color: #FFF;
  -webkit-transition: all .7s ease-in-out;

  -ms-transition: all .7s ease-in-out;
  -o-transition: all .7s ease-in-out;
  transition: all .7s ease-in-out;
}

.sidebar-anchor:hover:before { width: 100%; }

5. Style and position the toggle buttons.

.bar {
  display: block;
  height: 5px;
  width: 50px;
  background-color: #EF8354;
  margin: 10px auto;
}

.button {

  display: inline-block;
  width: auto;
  margin: 0 auto;
  -webkit-transition: all .7s ease;
  -moz-transition: all .7s ease;
  -ms-transition: all .7s ease;
  -o-transition: all .7s ease;
  transition: all .7s ease;
}

.nav-right {
  position: fixed;
  right: 40px;
  top: 20px;
}

.nav-right.visible-xs { z-index: 3; }

.hidden-xs { display: none; }

.middle { margin: 0 auto; }

.bar {
  -webkit-transition: all .7s ease;
  -moz-transition: all .7s ease;
  -ms-transition: all .7s ease;
  -o-transition: all .7s ease;
  transition: all .7s ease;
}

.nav-right.visible-xs .active .bar {
  background-color: #FFF;
  -webkit-transition: all .7s ease;
  -moz-transition: all .7s ease;
  -ms-transition: all .7s ease;
  -o-transition: all .7s ease;
  transition: all .7s ease;
}

.button.active .top {
  -webkit-transform: translateY(15px) rotateZ(45deg);
  -moz-transform: translateY(15px) rotateZ(45deg);
  -ms-transform: translateY(15px) rotateZ(45deg);
  -o-transform: translateY(15px) rotateZ(45deg);
  transform: translateY(15px) rotateZ(45deg);
}

.button.active .bottom {
  -webkit-transform: translateY(-15px) rotateZ(-45deg);
  -moz-transform: translateY(-15px) rotateZ(-45deg);
  -ms-transform: translateY(-15px) rotateZ(-45deg);
  -o-transform: translateY(-15px) rotateZ(-45deg);
  transform: translateY(-15px) rotateZ(-45deg);
}

.button.active .middle { width: 0; }
