Responsive Navigation, inspired by the technique used in Brad Frost's Mobile-First Demo (http://bradfrostweb.com/demo/mobile-first/).

responsive-nav.js

$(document).ready(function() {

	$('body').addClass('js');
	var $menu = $('#nav'),
	$search = $('.search-bar'),
	$menulink = $('.menu-link'),
	$searchlink = $('.search-link');

	$menulink.click(function() {
      		$menulink.toggleClass('active');
     		$searchlink.removeClass('active');
	    	$menu.toggleClass('active');
	    	$search.removeClass('active');
	return false;
	});

	$searchlink.click(function() {
  	  	$menulink.removeClass('active');
  	  	$searchlink.toggleClass('active');
	  	$menu.removeClass('active');
		$search.toggleClass('active');
  	return false;
	});

});
