const toggleList = document.getElementById('toggleList'); const listDiv = document.querySelector('.list'); const input = document.querySelector('input.description'); const p = document.querySelector('p.description'); const button = document.querySelector('button.description');
toggleList.addEventListener('click', () => { if (listDiv.style.display == 'none') { toggleList.textContent = 'Hide List'; listDiv.style.display = 'block'; } else { toggleList.textContent = 'Show list'; listDiv.style.display = 'none'; } });
button.addEventListener('click', () => { p.innerHTML = input.value + ':'; });
The second button in this .js file no longer does anything. I can't figure why that is.

And to make posted code easier to read, use the instructions for code formatting in the Markdown Cheatsheet pop-up below the "Add an Answer" area.
