CSS::DOM::Rule(3pm) User Contributed Perl Documentation CSS::DOM::Rule(3pm) 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 SEE ALSO
