For text, we set the type attribute to "text" to make the input element a text field.

<html>
<head><style>body {min-height: 300px;} input { font-size: 16px; } textarea { font-size: 16px; } </style></head>
<body>
  <h1>Sign up</h1>
  <input type="text">
</body>
</html>]]>

Make sure to assemble type="text".
