Online collection of meta-functions in HTML

This is stated on the W3cschool:

The <meta> element provides meta-information about the page (meta-information), such as descriptions and keywords for search engines and update frequency.

The <meta> tag is located in the header of the document and does not contain any content. The properties of the <meta> tag define the name/value pairs associated with the document.

The difference between HTML and XHTML

The,<meta> tag does not have an end tag in HTML.

In XHTML, the,<meta> tag must be properly closed.

Tips and Comments:

Note The:<meta> tag is always inside the head element.

Note: Metadata is always passed in pairs in the form of a name/value.

The Name property provides the names in the name/value pairs. Neither HTML nor XHTML tags specify any pre-defined <meta> names. Typically, you are free to use a meaningful name for yourself and the reader of your source document.

When using the <meta> tag with the Http-equiv property, the server adds a name/value pair to the header of the content sent to the browser.

Content Properties

The Content property provides the value in a name/value pair. The value can be any valid string.

The content property is always used with the Name property or the Http-equiv property.
