input elements can only be text fields with a single line. To create a multiple-line text area, we use the textarea element.

Create a text area using the <textarea> and </textarea> tags.

<html>
<head><style>body {min-height: 300px;} input { font-size: 16px; } textarea { font-size: 16px; } </style></head>
<body>
  <h1>Leave a Review</h1>
  <textarea></textarea>
</body>
</html>]]>

Make sure to place the opening tag before the closing tag: <textarea></textarea>.
