HTML

HyperText Markup Language (HTML) is used to create electronic documents that are displayed on the Web. An HTML document is composed of three parts: a line containing HTML version information, a declarative header section, and a body, which contains the document's actual content. The head of an HTML document is the part that is not displayed in the web browser when the page is loaded. It contains information such as the page <title>, links to CSS (if you want to style your HTML content with CSS), links to custom favicon  and other metadata (data about the HTML, such as who wrote it, and important keywords that describe the document.) In this article we'll cover all the above things and more, to give you a good basis for dealing with markup and other code that should live in your head.
