Do not understand why my button "change list description" does not work any more.

Could somebody help me to understand why the button <button class"description"> doesn't work? Thanks!

<!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 class="list"> <p class="description">Things that are purple:</p> <input type="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>

//toggle list const toggleList = document.getElementById('toggleList'); const listDiv = document.querySelector('.list') // description const input=document.querySelector('input.description'); const p=document.querySelector('p.description'); const button=document.querySelector('button.description');

//description button.addEventListener("click", () => { p.textContent = input.value + ':' })
