</nav>

JavaScript

The hexagonal menu uses a small amount of js code to listen to the mouse click event of the button, and add and remove the corresponding class for it.

var hexNav = document.getElementById('hexNav');
 
document.getElementById('menuBtn').onclick = function() {
    var className = ' ' + hexNav.className + ' ';
    if ( ~className.indexOf(' active ') ) {
        hexNav.className = className.replace(' active ', ' ');
    } else {
        hexNav.className += ' active';
    }              
}
