HTML | <isindex> tag

Last Updated : 15 Sep, 2021

The <isindex> tag is used to querying any document through a text field. Means this tag inform the browser that the user wants to provide the search function through the document. If you want to search any specific word in a long article this tag is helpful then. But during these days all the browsers contain that feature by pressing CTRL + F will let you search the word, so this tag is no more useful these days.

Syntax:

<isindex prompt="search">

Attribute:

prompt: This attribute contains a string which is label for the text field.
action: This attribute holds the URL when you need to send the query to a different URL.

Note: HTML5 does not support <isindex> tag.

Example:

HTML

<!Doctype html>
<html>
 
<head>
    <title>HTML isindex Tag</title>
    <isindex prompt="Search" />
    <style>
        h1 {
            color: green;
        }
    </style>
</head>
