<scriptsrc="//ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js">
</script>
<scripttype="text/javascript">
jQuery(document).ready(function(){
// $ == jQuery, so you can use either $ or jQuery.
$(".world").hide();
// world is the World span class, inorder to access the class we should use .class (i.e) .world
 $("#hello").click(function(){
// hello is the Hello span id, inorder to access the id we should use #id (i.e) #hello
  $(".world").show();
  });
$(".world").click(function(){
$(".world").hide();
