Animated hamburger menu


Small interactive UI animations communicate state and purpose to users. A common case is a hamburger menu button that animates into an "X" when open. This animation communicates that the user can press the same button again to close the menu.

CSS animations

Below is the custom styles and CSS animations for the hamburger menu:

<style amp-custom>
  .hamburger_wrapper {
    padding: 5px;
    z-index: 10;

  #hamburger {
    width: 60px;
    height: 45px;
    position: relative;
    cursor: pointer;
    outline: none;

  #hamburger span {
    display: block;
    position: absolute;
    height: 9px;
    width: 100%;
    border-radius: 9px;
    opacity: 1;
    left: 0;
    transform: rotate(0deg);
    transition: .5s ease-in-out;

  #hamburger span:nth-child(1) {
    top: 0px;
    transform-origin: left center;

  #hamburger span:nth-child(2) {
    top: 21px;
    transform-origin: left center;

  #hamburger span:nth-child(3) {
    top: 42px;
    transform-origin: left center;

  #hamburger.close span:nth-child(1) {
    transform: rotate(45deg);

  #hamburger.close span:nth-child(2) {
    width: 0%;
    opacity: 0;
    transition: .1s;

  #hamburger.close span:nth-child(3) {
    transform: rotate(-45deg);
  #nav-menu {
    position: relative;
    transform: translateX(-100vw);
    opacity: 0;
    z-index: 10;
    transition: transform .5s ease, opacity ease .2s;
  } {
    transform: translateX(0);
    transition: transform .5s ease, opacity ease .2s;
    opacity: 1;

  .nav-list {
    padding: 10px;
    list-style-type: none;
    font-size: 2em;


The hamburger menu element contains three styled span elements inside a div. The hamburger div uses the tap AMP action to trigger the toggleClass() event, which targets an element by its id. In this example, it targets hamburger.

The toggleClass() event will add and remove any class it's given as an argument. This example passes class='close'. Additionally, it toggles an animation class for the navigation menu to slide out.
