Tag Description

The meta tag is used to provide metadata about the HTML document. Metadata is not rendered on the page, but is browser parsable.

Metadata elements are typically used to specify the document description, keywords, and author information.

This tag has the form:

<meta content="text" { http-equiv="http response header" | name="text" } />

Note: The <meta> tag must be placed within the head element.
