What Are Declaration Blocks?
Declaration Blocks begin with a left curly brace ('{') and end when a matching right curly brace ('}') is reached. Between these braces lie semi-colon separated style declarations.

A style declaration consists of a simple assignment: a CSS property is given a specific value. This is the heart of CSS - the assignment of rendering properties. A CSS property is followed by a colon character (':'), which is followed in turn by a value appropriate to the property. White space around all of these declaration components is optional.

Syntax: "{" [space]? [Property] [space]? ":" [space]? [Value] [space]? "}"
Example:
{ font-size: 14pt }
Declaration Groupings
[CSS1|CSS2] [IE3|N4|O3.5]
A Selector may be repeated multiple times in order to assign multiple properties, or alternatively, multiple declarations can be lumped together within a Declaration Block for the Selector in order to save space. Multiple declarations are separated by semi-colon characters (';'), with White space around the semi-colon being optional.

Example
h1 { font-size: 14pt }
h1 { color: green }
h1 { font-weight: bold }
     Becomes =>      h1 {
font-size: 14pt;
color: green;
font-weight: bold
}
Shorthand Properties
[CSS1|CSS2] [IE3|N4|O3.5]
Thankfully, the creators of CSS realize that there are a LOT of properties, many of which accomplish similar tasks. Some CSS properties exist to serve as a shorthand for specifying several other property/values at once.

Example:
{ font: bold small-caps 12pt/14pt sans-serif }
is the same as
{ font-weight: bold; font-variant: small-caps; font-size: 12pt; line-height: 14pt; font-family: sans-serif }


CSS shorthand properties:
Font | Background | List-style | Outline | Pause | Cue | Layout-grid | Margin | Padding
Border | Border-top | Border-right | Border-bottom | Border-left | Border-width | Border-style | Border-color
