What could be the reason for the malfunctioning of my JavaScript code?

I have obtained some code from a tutorial on coding website called JSFiddle

$(function() {
    $('.toggler').click(function() {
        $(this).find('div').slideToggle();
    });
});

<div class="toggler"> This is the title 
<div> This is the content to be toggled </div>

div.toggler { background:lightblue; cursor:pointer; }
div.toggler div { display:none; }

I am attempting to recreate this functionality on my own website, but it seems to not be working as expected. The content is displayed, but clicking on it does nothing. Here is the code:

div.toggler { background:lightblue; cursor:pointer; }
div.toggler div { display:none; }
<!DOCTYPE html>
<html>
<head>
<link href="design.css" rel="stylesheet" type="text/css" />
<script type="text/javascript">
$(function() {
    $('.toggler').click(function() {
        $(this).find('div').slideToggle();
   });
});
</script>
</head>
<body>
<div class="toggler"> This is the title 
    <div> This is the content to be toggled </div>
</div>
</body>
</html>

Please note that you can also view the intended functionality by visiting the provided JSFiddle link.

For your code to work properly, make sure to include the jQuery library.

<head>
    <link href="design.css" rel="stylesheet" type="text/css" />
    <script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.0.0-alpha1/jquery.min.js"></script>
    <script type="text/javascript">
        $(function() {
            $('.toggler').click(function() {
                $(this).find('div').slideToggle();
            });
        });
    </script>
</head>

It is recommended to place your script tag containing your code right after all the HTML before the closing of the body tag. This helps prevent any interference with browser rendering during JS compilation.
