You'll see an error when you click the button related to the following: 

p = document.querySelector('p.description')

p.description in querySelector will select the first paragraph element with the class description. Your html currently doesn't have one.

This:

<p>Things that are purple:</p>

should be:

<p class="description">Things that are purple:</p>
