  <h1>Lesson 5 - Editing HTML with JavaScript</h1>
  <div class="dotted-div">
    <h2>Task 1: Finding Elements on the page using JavaScript</h2>
    <div class="info">You can find an element on the page using JavaScript, using code that looks like this:
      <code>document.querySelector("#my-element-name")</code>. This allows you to edit your HTML page with JavaScript.
    </div>
    <p>Update <code>document.querySelector("#I-CANT-FIND-MY-ELEMENT")</code> to instead look for an element with the id
      of
      <code>#update-text</code>. When you refresh the page, the new JavaScript text should overwrite the original HTML
      message.
    </p>
    <p><strong>Bonus:</strong> Update the JavaScript message to say something new, like "Hello!"</p>

    <strong id="update-text">
      This is the original HTML text. If you can still see it, it means you haven't found the
      element successfully in JavaScript :(</strong>
  </div>
  <div class="key-takeaways">
    <h2>Key Takeaways</h2>
