Everything was okay but I added class (.description) to const input and const button, and there is something wrong. Please check the codes.
<!DOCTYPE html> <html> <head> <title>JavaScript and the DOM</title> <link rel="stylesheet" href="css/style.css"> </head> <body> <h1 id="myHeading">JavaScript and the DOM</h1> <p>Making a web page interactive</p> <button id="toggleList">Hide List</button> <div> <p class="description">Things that are purple:</p> <input style="text" class="description"> <button class="description">Change list description</button> <ul> <li>grapes</li> <li>amethyst</li> <li>lavender</li> <li>plums</li> </ul> </div> <script src="app.js"></script> </body> </html>
const toggleList = document.querySelector('#toggleList'); const div = document.querySelector('div'); const input = document.querySelector('input.description'); const p = document.querySelector('p.description'); const button = document.querySelector('button.description');
button.addEventListener('click', () =>{ if (div.style.display =='none') { toggleList.textContent = 'Hide List'; div.style.display = 'block'; } else { toggleList.textContent = 'Show List'; div.style.display = 'none'; } })
button.addEventListener('click', ()=>{ p.textContent = input.value+ ':'; });

Full Stack JavaScript Techdegree Student 13,459 PointsI figured it out in the next video. I don't know if he changed it and the video did not show us between this one and the next, but where you and I both had:
button.addEventListener('click', () =>{ if (div.style.display =='none') { toggleList.textContent = 'Hide List'; div.style.display = 'block'; } else { toggleList.textContent = 'Show List'; div.style.display = 'none'; } })
It should be:
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'; } });
toggleList instead of button at the beginning is what the issue was.

Full Stack JavaScript Techdegree Student 13,459 PointsSame exact thing happened to me. I checked every line of code against Guil's and mine was the same but I have the same issue as you, the click/toggle stopped working. Did you ever figure out why? I'd love to know!
