You need to put the HTML elements (starts with <h1 class="text-center white-text">Krewella</h1> in your code) into the HTML section of codepen.
Everything you put inside the <style>...</style> should stay in the CSS section, but remove <style> and </style>.
I am not sure what is that text doing in the JavaScript section, but you’ll have to remove that, too. The JS section should hold the JavaScript portion of the code only. Since this is the first project, you probably don’t need to use this section at all.
I can see you put an effort to style the submit button. However, the text is not centered on the button. You can fix that by changing the button width.
If you want to keep your note in the JavaScript panel, please, comment it putting a // before your text, else you’ll get an “Unexpected Identifier” error…
