NAME
       CSS::DOM::Rule - CSS rule class for CSS::DOM

VERSION
       Version 0.14

SYNOPSIS
	 use CSS::DOM::Rule ':all'; # import constants

	 use CSS::DOM;
	 $sheet = new CSS::DOM;
	 $sheet->insertRule('bla blah blah {}');
	 $rule = $sheet->cssRules->[0];

	 $rule->type; # STYLE_RULE
	 $rule->cssText; # 'bla blah blah {}' or similar
	 $rule->cssText('p { margin: 0 }'); # replace it
	 $rule->parentStyleSheet; # $sheet

DESCRIPTION
       This module provides the CSS rule class for CSS::DOM. It implements the
       CSSRule and CSSUnknownRule DOM interfaces.

METHODS
   Constructor
       Only call the constructor on this class to create an 'unknown' rule.
       You have to call the constructor on a particular subclass to get
       another type. Normally you do not need to call this directly anyway.
       (See CSS::DOM's "parse" and "insertRule" methods.) But just in case you
       do want to call it, here it is:

	 new CSS::DOM::Rule $parent; # unknown rule

	 require CSS::DOM::Rule::Style
	 new CSS::DOM::Rule::Style $parent;
	 # etc.

       $parent is the parent rule, if the rule is nested, or the parent style
       sheet otherwise.

   Object Methods
       type
	   Returns one of the constants below indicating the type of rule.

       cssText
	   Returns this rule's CSS code. If you pass an argument, it will be
	   parsed as the new CSS code for this rule (replacing the existing
	   data), and the old value will be returned. This method will die if
	   the replacement CSS code creates a different type of rule.

       parentStyleSheet
	   This returns the style sheet to which the rule belongs.

       parentRule
	   This returns the rule's parent rule, if there is one, or an empty
	   list otherwise. There is only a parent rule if this one is nested,
	   e.g., inside a media rule.

EXPORTS
       The following constants that indicate the type of rule will be exported
       on request (individually or with the ':all' tag):

	 UNKNOWN_RULE
	 STYLE_RULE
	 CHARSET_RULE
	 IMPORT_RULE
	 MEDIA_RULE
	 FONT_FACE_RULE
	 PAGE_RULE
