DESCRIPTION

25       This module provides the CSS style declaration class for CSS::DOM. (A
26       style declaration is what comes between the braces in "p { margin: 0
27       }".)  It implements the CSSStyleDeclaration DOM interface.
28

CONSTRUCTORS

30       CSS::DOM::Style::parse( $string )
31       CSS::DOM::Style::parse( $string, property_parser => $parser )
32           This parses the $string and returns a new style declaration object.
33           This is useful if you have text from an HTML "style" attribute, for
34           instance.
35
36           For details on $property_parser, see CSS::DOM::PropertyParser.
37
38       new CSS::DOM::Style $owner_rule
39       new CSS::DOM::Style owner => $owner_rule, property_parser => $p
40           You don't normally need to call this, but, in case you do, here it
41           is.  $owner_rule, which is optional, is expected to be a
42           CSS::DOM::Rule object, or a subclass like CSS::DOM::Rule::Style.
43

METHODS

45       cssText ( $new_value )
46           Returns the body of this style declaration (without the braces). If
47           you pass an argument, it will parsed and replace the existing CSS
48           data.
49
50       getPropertyValue ( $name )
51           Returns the value of the named CSS property as a string.
52
53       getPropertyCSSValue ( $name )
54           Returns an object representing the property's value.  (See
55           CSS::DOM::Value.)
56
57       removeProperty ( $name )
58           Removes the named property, returning its value.
59
60       getPropertyPriority
61           Returns the property's priority. This is usually the empty string
62           or the word 'important'.
63
64       setProperty ( $name, $value, $priority )
65           Sets the CSS property named $name, giving it a value of $value and
66           setting the priority to $priority.
67
68       length
69           Returns the number of properties
70
71       item ( $index )
72           Returns the name of the property at the given index.
73
74       parentRule
75           Returns the rule to which this declaration belongs.
76
77       modification_handler ( $coderef )
78           This method, not part of the DOM, allows you to attach a call-back
79           routine that is run whenever a change occurs to the style object
80           (with the style object as its only argument). If you call it
81           without an argument it returns the current handler. With an
82           argument, it returns the old value after setting it.
83
84       property_parser
85           This returns the parser that was passed to the constructor.
86
87       This module also has methods for accessing each CSS property directly.
88       Simply capitalise each letter in a CSS property name that follows a
89       hyphen, then remove the hyphens, and you'll have the method name. E.g.,
90       call the "borderBottomWidth" method to get/set the border-bottom-width
91       property.  One exception to this is that "cssFloat" is the method used
92       to access the 'float' property. (But you can also use the "float"
93       method, though it's not part of the DOM standard.)
