A modern mobile app style navigation solution that makes uses of jQuery and CSS3 to create an off-canvas sidebar push menu with a fancy elastic effect.

How to use it:

1. Include the Font Awesome in the head section (Optional. Just for menu toggle icon).

<link rel="stylesheet" href="//netdna.bootstrapcdn.com/font-awesome/4.3.0/css/font-awesome.min.css">

2. Create a trigger button to toggle the off-canvas push menu.

<div class="button">
  <div class="fa fa-bars"></div>
</div>

3. Create a nav list that contains menu links pointing to the content sections of your web page.

<div class="menu">
  <nav>
    <ul>
      <li> <a href="home_is_visible">Home</a> </li>
      <li> <a href="aboutus_is_visible">About</a> </li>
      <li> <a href="clients_is_visible">Clients</a> </li>
      <li> <a href="contactus_is_visible">Contact Us</a> </li>
    </ul>
  </nav>
</div>

4. Create sections of content as follow.

<div class="content home">
  <h1>Home</h1>
  <p>...</p>
</div>

<div class="content aboutus">
  <h1>About Us</h1>
  <p>...</p>
</div>

<div class="content clients">
  <h1>Clients</h1>
  <p>...</p>
</div>

<div class="content contactus">
  <h1>Contact Us</h1>
  <p>...</p>
</div>
