Code not working, down button super tiny, no error in console

The "Up" and "Remove" buttons are functional and are normal but the "Down" button doesn't work and is a tiny gray button. I think I followed all the instructions. My workspace is https://w.trhou.se/dob28kh6aw

Hi there, babyoscar! First, thank you for posting a shareable snapshot to your workspace. This was tremendously helpful! :smiley:

The problem with the "down" button actually lies in the "remove" button.

On lines 17 - 20, you create the down button, set the class and attach it to the DOM. But then, immediately after, on lines 22 - 25, you overwrite those. On lines 22-25 you have this:

let remove = document.createElement('button');
down.className = 'remove';  // this should be remove.className
down.textContent = 'Remove';  // this should be remove.textContent
li.appendChild(remove);

But you meant:

let remove = document.createElement('button');
remove.className = 'remove';
remove.textContent = 'Remove';  
li.appendChild(remove);

Hope this helps! :sparkles:
