In testing your code I received a different error:

Bummer: There was an error with your code: TypeError: 'undefined' is not a function (evaluating 'contentDiv.appendchild(newParagraph)')

This is because the C in appendChild should be uppercase.

Good catch. I missed that.

The third line, where you attempt to add a class to the new Element, is incorrect.

To attach a CSS class to an element via code we use the classList property which has a method called, add().

It should look like:

newParagaph.classList.add('panel');

contentDiv.appendChild(newParagraph)

works well
