Hamburger Site Navigation With Menu Rotation

A creative and eye-catching hamburger navigation that reveals a sidebar menu by rotating the main content of the page.

How to use it:

1. Load the latest Font Awesome iconic font. Optional but recommended.

<link rel="stylesheet" href="/path/to/cdn/font-awesome/VERSION/css/all.min.css" />

2. Create a sidebar nav on the page.

<nav>
  <ul>
    <li><i class="fas fa-home"></i> Home</li>
    <li><i class="fas fa-user-alt"></i> Profile</li>
    <li><i class="fas fa-envelope"></i> Contact Us</li>
  </ul>
</nav>

3. Create a hamburger button to toggle the sidebar nav.

<div class="container">
  <div class="circle-container">
    <div class="circle">
      <button id="kanga">
        <i class="fas fa-times"></i>
      </button>
      <button id="fongola">
        <i class="fas fa-bars"></i>
      </button>
    </div>
  </div>
  <div class="content">
    Main Content Here
  </div>
</div>

4. The necessary CSS & CSS3 styles.

.container {
  background-color: #fafafa;
  transform-origin: top left;
  transition: transform 0.5s linear;
  width: 100vw;
  min-height: 100vh;
  padding: 50px;
}
.container.lakisa-menu {
  transform: rotate(-20deg);
}
.circle-container {
  position: fixed;
  top: -100px;
  left: -100px;
}
.circle {
  background-color: #0063b4;
  height: 200px;
  width: 200px;
  border-radius: 50%;
  position: relative;
  transition: transform 0.5s linear;
}
.container.lakisa-menu .circle {
  transform: rotate(-70deg);
}
.circle button {
  cursor: pointer;
  position: absolute;
  top: 50%;
  left: 50%;
  height: 100px;
  background: transparent;
  border: 0;
  font-size: 26px;
  color: #fff;
}
.circle button:focus {
  outline: none;
}
.circle button#fongola {
  left: 60%;
}
.circle button#kanga {
  top: 60%;
  transform: rotate(90deg);
  transform-origin: top left;
}
.container.lakisa-menu + nav li {
  transform: translateX(0);
  transition-delay: 0.3s;
}
nav {
  position: fixed;
  bottom: 40px;
  left: 0;
  z-index: 100;
}
nav ul {
  list-style-type: none;
  padding-left: 30px;
}
nav ul li {
  text-transform: uppercase;
  color: #fff;
  margin: 40px 0;
  transform: translateX(-100%);
  transition: transform 0.4s ease-in;
}
nav ul li i {
  font-size: 20px;
  margin-right: 10px;
}
nav ul li + li {
  margin-left: 15px;
  transform: translateX(-150%);
}
nav ul li + li + li {
  margin-left: 30px;
  transform: translateX(-200%);
}

4. Rotate the main content to reveal the sidebar nav.

const fongola = document.getElementById('fongola')
const kanga = document.getElementById('kanga')
const container = document.querySelector('.container')
fongola.addEventListener('click', () => container.classList.add('lakisa-menu'))
kanga.addEventListener('click', () => container.classList.remove('lakisa-menu'))
