Terminology

If you ever wanted a mini-cheat sheet for what every part of a CSS rule is called, here it is:

• The whole thing is a ruleset.
• The curly braces and everything inside is a declaration block.
• The bit before the opening curly brace is a selector.
• Each key/value pair, as separated by a colon and ending in a semicolon, is a declaration.
• In those key/value pairs, the key is a property (or property name), and the value is a value (or property value).
