The link you posted looks to be the link to the freeCodeCamp CodePen template. Please edit your post and update the link to your project so that others can help you out.
@baruaremy you probably need to click the button labeled Fork in the CodePen interface. That will make a copy of the project under your account and save your code changes in your copy. The link you copy and paste here should show your username in the url, similar to how miku86 pointed out for the freeCodeCamp user link you’ve shared previously.
