// Use these terms when applicable (see http://www.xanthir.com/blog/b4E50)
//
// rule** or **ruleset:
// A selector + braces combo, or an at-rule.
//
// declaration block:
// A sequence of declarations.
//
// declaration:
// A property + colon + value combo.
//
// property value:
// The entire value of a property.
//
// component value:
// A single piece of a property value. Like the 5px in
// text-shadow: 0 0 5px blue;. Can also refer to things that are
// multiple terms, like the 1-4 terms that make up the background-size
// portion of the background shorthand.
//
// term:
// The basic unit of author-facing CSS, like a single number (5),
// dimension (5px), string ("foo"), or function. Officially defined
// by the CSS 2.1 grammar (look for the 'term' production)
//
//
// simple selector:
// A single atomic selector, like a type selector, an attr selector, a
// class selector, etc.
//
// compound selector:
// One or more simple selectors without a combinator. div.example is
// compound, div > .example is not.
//
// complex selector:
// One or more compound selectors chained with combinators.
//
// combinator:
// The parts of selectors that express relationships. There are four
// currently - the space (descendant combinator), the greater-than
// bracket (child combinator), the plus sign (next sibling combinator),
// and the tilda (following sibling combinator).
//
// sequence of selectors:
// One or more of the named type of selector chained with commas.
