    padding: 50px 0;
    text-align: center;
    background-color: lightblue;
    margin-top:20px;
}
</style>
</head>

so you ned to include JQuery that's what $() is.

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>

<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<style>
#myDIV {
    width: 100%;
    padding: 50px 0;
    text-align: center;
    background-color: lightblue;
    margin-top:20px;
}
</style>
</head>
<body>


<body>
    Click a button to make it visible:<br /><br />
<a href="#" class="one">One</a>
<a href="#" class="two">Two</a>
<a href="#" class="three">Three</a>
<a href="#" class="four">Four</a><br /><br />

    <div id="one">One</div>
    <div id="two">Two</div>
    <div id="three">Three</div>
    <div id="four">Four</div><br/><br/>




</body>


<script>
$("div").hide();
          // Show chosen div, and hide all others
        $("a").click(function (e) 
        {
            //e.preventDefault();
            $("#" + $(this).attr("class")).show().siblings('div').hide();
        });
</script>

You should add the <script> tag in the head or body and not before the <!doctype html>

You should add jquery in your project. You can use a CDN

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>

OR

you can include your own copy of library in project.

 <script src="path/jquery.min.js"></script>
