General Meta-Tag Comments

A meta-tag is a special HTML tag that is used to store information about a Web page

but is not displayed in a Web browser. For example, meta tags provide information

such as what program was used to create the page, a description of the page, and

keywords that are relevant to the page.

As per the HTML specification, all meta-tags must be contained within a <head> …

</head> tag set.
