A CSS rule such as
Button { color: #FF0000 }
affects every instance of the Button class;
a selector like Button is called a type selector
and must not start with a dot.
A CSS rule such as
.redButton { color: #FF0000 }
affects only components whose styleName property
is set to "redButton";
a selector like .redButton is called a class selector
and must start with a dot.
You can access the autogenerated CSSStyleDeclaration objects
using the StyleManager.getStyleDeclaration() method,
passing it either a type selector
var buttonDeclaration:CSSStyleDeclaration =
StyleManager.getStyleDeclaration("Button");
or a class selector
var redButtonStyleDeclaration:CSSStyleDeclaration =
StyleManager.getStyleDeclaration(".redButton");
You can use the getStyle(), setStyle(),
and clearStyle() methods to get, set, and clear
style properties on a CSSStyleDeclaration.
You can also create and install a CSSStyleDeclaration at run time
using the StyleManager.setStyleDeclaration() method:
var newStyleDeclaration:CSSStyleDeclaration = new CSSStyleDeclaration(".bigMargins");
newStyleDeclaration.defaultFactory = function():void
{
leftMargin = 50;
rightMargin = 50;
}
StyleManager.setStyleDeclaration(".bigMargins", newStyleDeclaration, true);

This function, if it isn't null,
is usually autogenerated by the MXML compiler.
It produce copies of a plain Object, such as
{ leftMargin: 10, rightMargin: 10 },
containing name/value pairs for style properties; the object is used
to build a node of the prototype chain for looking up style properties.
If this CSSStyleDeclaration is owned by a UIComponent written in MXML, this function encodes the style attributes that were specified on the root tag of the component definition.
If the UIComponent was written in ActionScript,
this property is null.
