Why is this text area not displaying the correct number of columns?

<html>
<head><style>body {min-height: 300px;} input { font-size: 16px; } textarea { font-size: 16px; } </style></head>
<body>
  <h1>Send Feedback</h1>
  <textarea rows="3" columns="4"></textarea>
</body>
</html>]]>
It uses the wrong attribute for columnsIt misses the placeholder attribute

The attribute for columns should be cols.
