The stuff that describes the document
head

The head element comprises subordinate elements for the purpose of describing the document, its context, and its dependencies.
Every document must have a head element, and it should be the first descendent of the document's html element. At a minimum, the head must have a title element. Most documents will also have one or more meta and link elements.
Example
html {
head {
title Just Beyond the Thorny Divide
meta *charset=UTF-8
meta *name=description *content="A Series of Unhappy Events in Corslandia"
link `/css/thorny-divide.css` *rel=styleheet
}
}
Ancestor
- html
- The html element is the outermost envelope for the composition. It is often called the root element because HTML uses a hierarchical structure.
Descendants
- title
- The title element uses plain language to convey to prospective readers what the composition is about.
- meta
- Each meta element describes one facet of information about the document itself.
- base
- The base element overrides the document's point of reference.
- link
- The link element specifies where the browser can find additional resources needed to properly render the document.
- style
- The style element is used to declare CSS rules that will be applied to the document.
- script
- A script element allows the JavaScript language to be used to respond to user actions.
