2. Add modal header & body to the dialog box.

<div class="modal-overlay" id="modal">
  <div class="modal">
    <div class="modal-header">
      <div class="title">
        Modal Title
      </div>
      <button class="close-button" id="close-modal">&times;</button>
    </div>
    <div class="modal-body">
      Main Content Here
    </div>
  </div>
</div>
