HTML End Tag: Forbidden

The isindex element is a longtime holdover from the earliest days of HTML and is deprecated in HTML 4 in favor of the text input element. The isindex element tag belongs in the head element. In modern browsers, it is rendered as a simple text field between two hr elements. When a user types text into the field and presses the Enter/Return key, the content of the field is URL-encoded (with + symbols substituted for spaces) and sent to the server with the URL of the current document. A CGI program on the server must know how to process this URL and return HTML for display in the current window or frame.

Example

<HEAD>
<ISINDEX prompt="Enter a search string:">
</HEAD>
