Name
isindex — HTML 4.01
Synopsis
HTML: <isindex>; XHTML: <isindex/> or <isindex />
Marks the document as searchable. The server on which the
document is located must have a search engine that supports this
searching. The browser displays a text entry field and a generic line
that says, “This is a searchable
index. Enter search keywords.” The isindex
element is not part of the form
system and does not need to be contained within a form
element.
Notes
Deprecated in HTML 4.01/XHTML 1.0. Not in HTML5. This method is outdated; more sophisticated searches can be handled with form elements.
Start/End Tags
This is an empty element. In HTML, the end tag is forbidden. In XHTML, the element must be closed with a trailing slash as just shown. Developers may include a space character before the slash for backward compatibility with older browsers.
