Simple Javascript and CSS Popup for HTML not working

Question

Here is my JSfiddle sample for your reference.

HTML:

<a href='' class="photoclick"><h2><b>Click Here to See Popup! </b></h2></a> <br/>
<div class="popup">
    <div class="content">
        <img src="http://www.ge.com/ar2012/img/close-button-large.png" alt="quit" class="closephoto" id="closephoto" style="width:25px; height:25px"/>
        <p>
        Welcome Welcome Welcome Welcome Welcome Welcome Welcome
        </p>
    </div>
</div>   

JS:

$(function(){
    var overlay = $('<div id="photooverlay"></div>');

    $('.closephoto').click(function () {
        $('.popup').hide();
        overlay.appendTo(document.body).remove();
        return false;
    });

    $('.photoclick').click(function () {
        overlay.show();
        overlay.appendTo(document.body);
        $('.popup').show();
        return false;
    });
});

I tried running on browser, all I see is the grey out background nothing else. Please check my jsfiddle and tell me what's the issue

Edit: MY master page has

<script src="//code.jquery.com/jquery-1.9.1.js" type="text/javascript"></script>

still i can see only gray background only

Edit2: I have this on one of my asp Content page.My master page has

<link rel="stylesheet" href="//code.jquery.com/ui/1.10.4/themes/smoothness/jquery-ui.css" />
    <script src="//code.jquery.com/jquery-1.9.1.js" type="text/javascript"></script>
    <script src="//code.jquery.com/ui/1.10.4/jquery-ui.js" type="text/javascript"></script>
    <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>

Still I see only grey background

Answer 1

You missed having a jQuery library before the code and you have not imported or added a jQuery library in the fiddle itself.

      $(function(){});

You will need jQuery included before it's called.

Check out this fiddle.

Answer 2

When I zoomed out all the way I found the popup sneaking on the right side of the page. Sorry for the trouble guys. Carry on

Here is a working demo. Add jQuery in your HTML:

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>
