The head Element

The head element contains information that describes the (X)HTML document. This information is not considered part of the content of an (X)HTML page and is therefore not displayed in the viewport.

The head element must contain one title element.

These are the elements that head can contain:

• title
• base
• meta
• script
• link
• style
• object

There can be only one title and base element. However, the other elements can be present multiple times.
