Stylish Off-canvas Side Menu with JS and CSS

A stylish side navigation made by FictionTeam that creates a transparent off-canvas menu with CSS/CSS3 and a little bit of JavaScript.

How to use it:

Create a navigation button inside the main container with the CSS class of ‘container’.

<span class="nav__button"><i class="licon-reorder"></i></span>

Create an off-canvas menu next to the navigation button.

<nav class="navigation">
  <h3>My Navigation:</h3>
  <a href="#">Facebook</a>
  <a href="#">Google Plus</a>
  <a href="#">Twitter</a>
  <a href="#">Github</a>
  <a href="#">Instagram</a>
</nav>

The CSS/CSS3 to style the navigation button and to make it act like a hamburger button when toggled.

  position: fixed;
  bottom: 0;
  right: 0;
  margin: 1.75rem;

Enable the off-canvas menu with a little JavaScript.

var btn = document.querySelector('.nav__button'), 
    container = document.querySelector('.container');
btn.addEventListener('click', function () {
    this.classList.toggle('open');
    container.classList.toggle('active');
});
