Set the class attribute of the new paragraph to panel.

error message keeps saying it can't find "newParagraph". Not sure what the issue is. will not accept var or let in front of "newParapgraph" either

app.js 
var contentDiv = document.getElementById('content');
newParagraph.className = 'panel'
index.html 
<!DOCTYPE html>
<html>
    <head>
        <title>DOM Manipulation</title>
    </head>
    <link rel="stylesheet" href="style.css" />
    <body>
        <div id="content">

        </div>
        <script src="app.js"></script>
    </body>
</html>

Hi Marquis,

I think they first want you to use the createElement method to create the new element.

var contentDiv = document.getElementById('content');
var newParagraph = document.createElement('P');

Then they want you to set the class attribute of this newly create paragraph element to panel, you can do this with the setAttribute() method.:

var contentDiv = document.getElementById('content');
var newParagraph = document.createElement('P');

newParagraph.setAttribute("class", "panel");

Hope this helps.
