The <isindex> tag is an HTML tag that was introduced in the early days of the web. Its primary purpose is to create a simple search form that allows users to search for content on a website. While the <isindex> tag is still supported by most modern browsers, it is considered outdated and is no longer recommended for use. In this tutorial, we will cover the basics of the <isindex> tag and how it can be used.

When a user submits a search query using this form, the browser will redirect them to the search engine specified in the action attribute, along with the search query as a parameter.

Instead, modern web developers should use more modern techniques such as HTML5’s <input> element and CSS to create search forms that are both functional and aesthetically pleasing.
