JavaScript JavaScript and the DOM (Retiring) Making Changes to the DOM Styling Elements

Why is my button also disappearing on my page?

When I click the Hide List button my button also disappears and I'm not sure why. Am I missing something somewhere? As a result of this I am unable to re-show my list because my button disappears!

<!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>

    <div class="list">
    <button id="toggleList">Hide List</button>
    <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>
const toggleList = document.getElementById('toggleList');
const listDiv = document.querySelector('.list');
const input = document.querySelector('input');
const p = document.querySelector('p.description');
const button = document.querySelector('button');

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 + ':';
});

Your button is inside the div that you are hiding. Move it outside the div. This:

  <button id="toggleList">Hide list</button>
    <div class="list">

instead of this:

 <div class="list">
    <button id="toggleList">Hide List</button>

That worked, thank you!
