In order to switch the class, you need to perform some JavaScript.

In jQuery:

$('.menu li a').click(function(e) {
  var $this = $(this);
  if (!$this.hasClass('active')) {
    $this.addClass('active');
  }
  e.preventDefault();
});

In JavaScript:

var menu = document.querySelector('.menu');
var anchors = menu.getElementsByTagName('a');

for (var i = 0; i < anchors.length; i += 1) {
  anchors[i].addEventListener('click', function() { clickHandler(anchors[i]) }, false);
}

function clickHandler(anchor) {
  var hasClass = anchor.getAttribute('class');
  if (hasClass !== 'active') {
    anchor.setAttribute('class', 'active');
  }
}

I hope this helps.
