// find the pathname
var urlPath = window.location.pathname;
//convert to lowercase
urlPath.match(/\/(.*?)(\+|$)/)[1].toLowerCase();
// remove the first character
urlPath = urlPath.replace(/\//g, '-').slice(1);
//remove file extension
urlPath = urlPath.replace(/\.[^/.]+$/, "");
// add class to body
$(document.body).addClass(urlPath);
// If body has no class its propably the homepage
$('body:not([class])').addClass('home');
