5.1. Overview of the DOM Level 2 CSS Interfaces

The DOM Level 2 Cascading Style Sheets (CSS) interfaces are designed with the goal of exposing CSS constructs to object model consumers. Cascading Style Sheets is a declarative syntax for defining presentation rules, properties and ancillary constructs used to format and render Web documents. This document specifies a mechanism to programmatically access and modify the rich style and presentation control provided by CSS (specifically CSS level 2 [CSS2]). This augments CSS by providing a mechanism to dynamically control the inclusion and exclusion of individual style sheets, as well as manipulate CSS rules and properties.

The CSS interfaces are organized in a logical, rather than physical structure. A collection of all style sheets referenced by or embedded in the document is accessible on the document interface. Each item in this collection exposes the properties common to all style sheets referenced or embedded in HTML and XML documents; this interface is described in the Document Object Model StyleSheets. User style sheets are not accessible through this collection, in part due to potential privacy concerns (and certainly read-write issues).

For each CSS style sheet, an additional interface is exposed - the CSSStyleSheet interface. This interface allows access to the collection of rules within a CSS style sheet and methods to modify that collection. Interfaces are provided for each specific type of rule in CSS2 (e.g. style declarations, @import rules, or @font-face rules), as well as a shared generic CSSRule interface.

The most common type of rule is a style declaration. The CSSStyleRule interface that represents this type of rule provides string access to the CSS selector of the rule, and access to the property declarations through the CSSStyleDeclaration interface.

Finally, an optional CSS2Properties interface is described; this interface (if implemented) provides shortcuts to the string values of all the properties in CSS level 2.

All CSS objects in the DOM are "live", that is, a change in the style sheet is reflected in the computed and actual style.

A DOM application can use the hasFeature method of the DOMImplementation interface to determine whether the CSS interfaces are supported or not. The feature string for the CSS Model is "CSS". The existence within an implementation of the extended interfaces can also be queried using the hasFeature method.

5.2. CSS Fundamental Interfaces

The interfaces within this section are considered fundamental CSS interfaces, and must be supported by all conforming implementations of the CSS DOM module. These interfaces represent CSS style sheets specifically.

Interface CSSStyleSheet (introduced in DOM Level 2)

The CSSStyleSheet interface is a concrete interface used to represent a CSS style sheet i.e., a style sheet whose content type is "text/css".


IDL Definition
// Introduced in DOM Level 2:
interface CSSStyleSheet : stylesheets::StyleSheet {
 readonly attribute CSSRule ownerRule;
 readonly attribute CSSRuleList cssRules;
 unsigned long insertRule(in DOMString rule, 
 in unsigned long index)
 raises(DOMException);
 void deleteRule(in unsigned long index)
 raises(DOMException);
};

Attributes
cssRules of type CSSRuleList, readonly
The list of all CSS rules contained within the style sheet. This includes both rule sets and at-rules.

ownerRule of type CSSRule, readonly
If this style sheet comes from an @import rule, the ownerRule attribute will contain the CSSImportRule. In that case, the ownerNode attribute in the StyleSheet interface will be null. If the style sheet comes from an element or a processing instruction, the ownerRule attribute will be null and the ownerNode attribute will contain the Node.

Methods
deleteRule
Used to delete a rule from the style sheet.
Parameters
index of type unsigned long
The index within the style sheet's rule list of the rule to remove.

Exceptions

DOMException

INDEX_SIZE_ERR: Raised if the specified index does not correspond to a rule in the style sheet's rule list.

NO_MODIFICATION_ALLOWED_ERR: Raised if this style sheet is readonly.

No Return Value

insertRule
Used to insert a new rule into the style sheet. The new rule now becomes part of the cascade.
Parameters
rule of type DOMString
The parsable text representing the rule. For rule sets this contains both the selector and the style declaration. For at-rules, this specifies both the at-identifier and the rule content.

index of type unsigned long
The index within the style sheet's rule list of the rule before which to insert the specified rule. If the specified index is equal to the length of the style sheet's rule collection, the rule will be added to the end of the style sheet.

Return Value

unsigned long

The index within the style sheet's rule collection of the newly inserted rule.

Exceptions

DOMException

HIERARCHY_REQUEST_ERR: Raised if the rule cannot be inserted at the specified index e.g. if an @import rule is inserted after a standard rule set or other at-rule.

INDEX_SIZE_ERR: Raised if the specified index is not a valid insertion point.

NO_MODIFICATION_ALLOWED_ERR: Raised if this style sheet is readonly.

SYNTAX_ERR: Raised if the specified rule has a syntax error and is unparsable.

Interface CSSRuleList (introduced in DOM Level 2)

The CSSRuleList interface provides the abstraction of an ordered collection of CSS rules.


IDL Definition
// Introduced in DOM Level 2:
interface CSSRuleList {
 readonly attribute unsigned long length;
 CSSRule item(in unsigned long index);
};

Attributes
length of type unsigned long, readonly
The number of CSSRules in the list. The range of valid child rule indices is 0 to length-1 inclusive.

Methods
item
Used to retrieve a CSS rule by ordinal index. The order in this collection represents the order of the rules in the CSS style sheet.
Parameters
index of type unsigned long
Index into the collection

Return Value

CSSRule

The style rule at the index position in the CSSRuleList, or null if that is not a valid index.

No Exceptions

Interface CSSRule (introduced in DOM Level 2)

The CSSRule interface is the abstract base interface for any type of CSS statement. This includes both rule sets and at-rules. An implementation is expected to preserve all rules specified in a CSS style sheet, even if the rule is not recognized by the parser. Unrecognized rules are represented using the CSSUnknownRule interface.


IDL Definition
// Introduced in DOM Level 2:
interface CSSRule {
 // RuleType
 const unsigned short UNKNOWN_RULE = 0;
 const unsigned short STYLE_RULE = 1;
 const unsigned short CHARSET_RULE = 2;
 const unsigned short IMPORT_RULE = 3;
 const unsigned short MEDIA_RULE = 4;
 const unsigned short FONT_FACE_RULE = 5;
 const unsigned short PAGE_RULE = 6;
 readonly attribute unsigned short type;
 attribute DOMString cssText;
 // raises(DOMException) on setting
 readonly attribute CSSStyleSheet parentStyleSheet;
 readonly attribute CSSRule parentRule;
};

Definition group RuleType

An integer indicating which type of rule this is.

Defined Constants
CHARSET_RULE
The rule is a CSSCharsetRule.

FONT_FACE_RULE

parentStyleSheet of type CSSStyleSheet, readonly
The style sheet that contains this rule.

type of type unsigned short, readonly
The type of the rule, as defined above. The expectation is that binding-specific casting methods can be used to cast down from an instance of the CSSRule interface to the specific derived interface implied by the type.

Interface CSSStyleRule (introduced in DOM Level 2)

The CSSStyleRule interface represents a single rule set in a CSS style sheet.

SYNTAX_ERR: Raised if the specified rule has a syntax error and is unparsable.

Interface CSSFontFaceRule (introduced in DOM Level 2)

The CSSFontFaceRule interface represents a @font-face rule in a CSS style sheet. The @font-face rule is used to hold a set of font descriptions.


IDL Definition
// Introduced in DOM Level 2:
interface CSSFontFaceRule : CSSRule {
 readonly attribute CSSStyleDeclaration style;
};

Attributes
style of type CSSStyleDeclaration, readonly
The declaration-block of this rule.

Interface CSSPageRule (introduced in DOM Level 2)

The CSSPageRule interface represents a @page rule within a CSS style sheet. The @page rule is used to specify the dimensions, orientation, margins, etc. of a page box for paged media.


IDL Definition
// Introduced in DOM Level 2:
interface CSSPageRule : CSSRule {
 attribute DOMString selectorText;
 // raises(DOMException) on setting
 readonly attribute CSSStyleDeclaration style;
};

Attributes
selectorText of type DOMString
The parsable textual representation of the page selector for the rule.

NO_MODIFICATION_ALLOWED_ERR: Raised if this rule is readonly.

style of type CSSStyleDeclaration, readonly
The declaration-block of this rule.

Interface CSSImportRule (introduced in DOM Level 2)

The CSSImportRule interface represents a @import rule within a CSS style sheet. The @import rule is used to import style rules from other style sheets.


IDL Definition
// Introduced in DOM Level 2:
interface CSSImportRule : CSSRule {
 readonly attribute DOMString href;
 readonly attribute stylesheets::MediaList media;
 readonly attribute CSSStyleSheet styleSheet;
};

Attributes
href of type DOMString, readonly
The location of the style sheet to be imported. The attribute will not contain the "url(...)" specifier around the URI.

media of type stylesheets::MediaList, readonly
A list of media types for which this style sheet may be used.

styleSheet of type CSSStyleSheet, readonly
The style sheet referred to by this rule, if it has been loaded. The value of this attribute is null if the style sheet has not yet been loaded or if it will not be loaded (e.g. if the style sheet is for a media type not supported by the user agent).

Interface CSSCharsetRule (introduced in DOM Level 2)

The CSSCharsetRule interface represents a @charset rule in a CSS style sheet. The value of the encoding attribute does not affect the encoding of text data in the DOM objects; this encoding is always UTF-16. After a stylesheet is loaded, the value of the encoding attribute is the value found in the @charset rule. If there was no @charset in the original document, then no CSSCharsetRule is created. The value of the encoding attribute may also be used as a hint for the encoding used on serialization of the style sheet.

The value of the @charset rule (and therefore of the CSSCharsetRule) may not correspond to the encoding the document actually came in; character encoding information e.g. in an HTTP header, has priority (see CSS document representation) but this is not reflected in the CSSCharsetRule.


IDL Definition
// Introduced in DOM Level 2:
interface CSSCharsetRule : CSSRule {
 attribute DOMString encoding;
 // raises(DOMException) on setting
};

Attributes
encoding of type DOMString
The encoding information used in this @charset rule.
Exceptions on setting

DOMException

SYNTAX_ERR: Raised if the specified encoding value has a syntax error and is unparsable.

NO_MODIFICATION_ALLOWED_ERR: Raised if this encoding rule is readonly.

Interface CSSUnknownRule (introduced in DOM Level 2)

The CSSUnknownRule interface represents an at-rule not supported by this user agent.


IDL Definition
// Introduced in DOM Level 2:
interface CSSUnknownRule : CSSRule {
};

Interface CSSStyleDeclaration (introduced in DOM Level 2)

The CSSStyleDeclaration interface represents a single CSS declaration block. This interface may be used to determine the style properties currently set in a block or to set style properties explicitly within the block.

While an implementation may not recognize all CSS properties within a CSS declaration block, it is expected to provide access to all specified properties in the style sheet through the CSSStyleDeclaration interface. Furthermore, implementations that support a specific level of CSS should correctly handle CSS shorthand properties for that level. For a further discussion of shorthand properties, see the CSS2Properties interface.

This interface is also used to provide a read-only access to the computed values of an element. See also the ViewCSS interface.

Note: The CSS Object Model doesn't provide an access to the specified or actual values of the CSS cascade.


IDL Definition
// Introduced in DOM Level 2:
interface CSSStyleDeclaration {
 attribute DOMString cssText;
 // raises(DOMException) on setting
 DOMString getPropertyValue(in DOMString propertyName);
 CSSValue getPropertyCSSValue(in DOMString propertyName);
 DOMString removeProperty(in DOMString propertyName)
 raises(DOMException);
 DOMString getPropertyPriority(in DOMString propertyName);
 void setProperty(in DOMString propertyName, 
 in DOMString value, 
 in DOMString priority)
 raises(DOMException);
 readonly attribute unsigned long length;
 DOMString item(in unsigned long index);
 readonly attribute CSSRule parentRule;
};

Attributes
cssText of type DOMString
The parsable textual representation of the declaration block (excluding the surrounding curly braces). Setting this attribute will result in the parsing of the new value and resetting of the properties in the declaration block. It also allows the insertion of additional properties and their values into the block.

parentRule of type CSSRule, readonly
The CSS rule that contains this declaration block or null if this CSSStyleDeclaration is not attached to a CSSRule.

Methods
getPropertyCSSValue
Used to retrieve the object representation of the value of a CSS property if it has been explicitly set within this declaration block. This method returns null if the property is a shorthand property. Shorthand property values can only be accessed and modified as strings, using the getPropertyValue and setProperty methods.
Parameters
propertyName of type DOMString

Interface CSSValue (introduced in DOM Level 2)

The CSSValue interface represents a simple or a complex value. A CSSValue object only occurs in a context of a CSS property.


IDL Definition
// Introduced in DOM Level 2:
interface CSSValue {
 // UnitTypes
 const unsigned short CSS_INHERIT = 0;
 const unsigned short CSS_PRIMITIVE_VALUE = 1;
 const unsigned short CSS_VALUE_LIST = 2;
 const unsigned short CSS_CUSTOM = 3;
 attribute DOMString cssText;
 // raises(DOMException) on setting
 readonly attribute unsigned short valueType;
};

Definition group UnitTypes

An integer indicating which type of unit applies to the value.

Defined Constants
CSS_CUSTOM
The value is a custom value.

CSS_INHERIT

Exceptions on setting

DOMException

SYNTAX_ERR: Raised if the specified CSS string value has a syntax error (according to the attached property) or is unparsable.

NO_MODIFICATION_ALLOWED_ERR: Raised if this value is readonly.

valueType of type unsigned short, readonly
A code defining the type of the value as defined above.

Interface CSSPrimitiveValue (introduced in DOM Level 2)

The CSSPrimitiveValue interface represents a single CSS value. This interface may be used to determine the value of a specific style property currently set in a block or to set a specific style property explicitly within the block. An instance of this interface might be obtained from the getPropertyCSSValue method of the CSSStyleDeclaration interface. A CSSPrimitiveValue object only occurs in a context of a CSS property.

Conversions are allowed between absolute values (from millimeters to centimeters, from degrees to radians, and so on) but not between relative values. (For example, a pixel value cannot be converted to a centimeter value.) Percentage values can't be converted since they are relative to the parent value (or another property value). There is one exception for color percentage values: since a color percentage value is relative to the range 0-255, a color percentage value can be converted to a number; (see also the RGBColor interface).

Interface CSSValueList (introduced in DOM Level 2)

The CSSValueList interface provides the abstraction of an ordered collection of CSS values.

Some properties allow an empty list into their syntax. In that case, these properties take the none identifier. So, an empty list means that the property has the value none.


IDL Definition
// Introduced in DOM Level 2:
interface CSSValueList : CSSValue {
 readonly attribute unsigned long length;
 CSSValue item(in unsigned long index);
};

Attributes

Interface RGBColor (introduced in DOM Level 2)

The RGBColor interface is used to represent any RGB color value. This interface reflects the values in the underlying style property. Hence, modifications made to the CSSPrimitiveValue objects modify the style property.

A specified RGB color is not clipped (even if the number is outside the range 0-255 or 0%-100%). A computed RGB color is clipped depending on the device.

Even if a style sheet can only contain an integer for a color value, the internal storage of this integer is a float, and this can be used as a float in the specified or the computed style.

A color percentage value can always be converted to a number and vice versa.


IDL Definition
// Introduced in DOM Level 2:
interface RGBColor {
 readonly attribute CSSPrimitiveValue red;
 readonly attribute CSSPrimitiveValue green;
 readonly attribute CSSPrimitiveValue blue;
};

Attributes
blue of type CSSPrimitiveValue, readonly
This attribute is used for the blue value of the RGB color.

green of type CSSPrimitiveValue, readonly
This attribute is used for the green value of the RGB color.

red of type CSSPrimitiveValue, readonly
This attribute is used for the red value of the RGB color.

Interface Rect (introduced in DOM Level 2)

The Rect interface is used to represent any rect value. This interface reflects the values in the underlying style property. Hence, modifications made to the CSSPrimitiveValue objects modify the style property.


IDL Definition
// Introduced in DOM Level 2:
interface Rect {
 readonly attribute CSSPrimitiveValue top;
 readonly attribute CSSPrimitiveValue right;
 readonly attribute CSSPrimitiveValue bottom;
 readonly attribute CSSPrimitiveValue left;
};

Attributes
bottom of type CSSPrimitiveValue, readonly
This attribute is used for the bottom of the rect.

left of type CSSPrimitiveValue, readonly
This attribute is used for the left of the rect.

right of type CSSPrimitiveValue, readonly
This attribute is used for the right of the rect.

top of type CSSPrimitiveValue, readonly
This attribute is used for the top of the rect.

Interface Counter (introduced in DOM Level 2)

The Counter interface is used to represent any counter or counters function value. This interface reflects the values in the underlying style property. Hence, modifications made to the DOMString objects modify the style property.


IDL Definition
// Introduced in DOM Level 2:
interface Counter {
 readonly attribute DOMString identifier;
 readonly attribute DOMString listStyle;
 readonly attribute DOMString separator;
};

Attributes
identifier of type DOMString, readonly
This attribute is used for the identifier of the counter.

listStyle of type DOMString, readonly
This attribute is used for the style of the list.

separator of type DOMString, readonly
This attribute is used for the separator of the nested counters.

5.2.1. Override and computed style sheet

Interface ViewCSS (introduced in DOM Level 2)

This interface represents a CSS view. The getComputedStyle method provides a read only access to the computed values of an element.

The expectation is that an instance of the ViewCSS interface can be obtained by using binding-specific casting methods on an instance of the View interface.

Since a computed style is related to an Element node, if this element is removed from the document, the associated CSSStyleDeclaration and CSSValue related to this declaration are no longer valid.


IDL Definition
// Introduced in DOM Level 2:
interface ViewCSS : views::AbstractView {
 CSSStyleDeclaration getComputedStyle(in Element elt, 
 in DOMString pseudoElt);
};

Methods
getComputedStyle
This method is used to get the computed style as it is defined in [CSS2].
Parameters
elt of type Element
The element whose style is to be computed. This parameter cannot be null.

pseudoElt of type DOMString
The pseudo-element or null if none.

Return Value

CSSStyleDeclaration

The computed style. The CSSStyleDeclaration is read-only and contains only absolute values.

No Exceptions

Interface DocumentCSS (introduced in DOM Level 2)

This interface represents a document with a CSS view.

The getOverrideStyle method provides a mechanism through which a DOM author could effect immediate change to the style of an element without modifying the explicitly linked style sheets of a document or the inline style of elements in the style sheets. This style sheet comes after the author style sheet in the cascade algorithm and is called override style sheet. The override style sheet takes precedence over author style sheets. An "!important" declaration still takes precedence over a normal declaration. Override, author, and user style sheets all may contain "!important" declarations. User "!important" rules take precedence over both override and author "!important" rules, and override "!important" rules take precedence over author "!important" rules.

The expectation is that an instance of the DocumentCSS interface can be obtained by using binding-specific casting methods on an instance of the Document interface.


IDL Definition
// Introduced in DOM Level 2:
interface DocumentCSS : stylesheets::DocumentStyle {
 CSSStyleDeclaration getOverrideStyle(in Element elt, 
 in DOMString pseudoElt);
};

Methods
getOverrideStyle
This method is used to retrieve the override style declaration for a specified element and a specified pseudo-element.
Parameters
elt of type Element
The element whose style is to be modified. This parameter cannot be null.

pseudoElt of type DOMString
The pseudo-element or null if none.

Return Value

CSSStyleDeclaration

The override style declaration.

No Exceptions

5.2.2. Style sheet creation

Interface DOMImplementationCSS (introduced in DOM Level 2)

This interface allows the DOM user to create a CSSStyleSheet outside the context of a document. There is no way to associate the new CSSStyleSheet with a document in DOM Level 2.


IDL Definition
// Introduced in DOM Level 2:
interface DOMImplementationCSS : DOMImplementation {
 CSSStyleSheet createCSSStyleSheet(in DOMString title, 
 in DOMString media);
};

Methods
createCSSStyleSheet
Creates a new CSSStyleSheet.
Parameters
title of type DOMString
The advisory title. See also the Style Sheet Interfaces section.

media of type DOMString
The comma-separated list of media associated with the new style sheet. See also the Style Sheet Interfaces section.

Return Value

CSSStyleSheet

A new CSS style sheet.

No Exceptions

5.2.3. Element with CSS inline style

Interface ElementCSSInlineStyle (introduced in DOM Level 2)

Inline style information attached to elements is exposed through the style attribute. This represents the contents of the STYLE attribute for HTML elements (or elements in other schemas or DTDs which use the STYLE attribute in the same way). The expectation is that an instance of the ElementCSSInlineStyle interface can be obtained by using binding-specific casting methods on an instance of the Element interface when the element supports inline CSS style informations.


IDL Definition
// Introduced in DOM Level 2:
interface ElementCSSInlineStyle {
 readonly attribute CSSStyleDeclaration style;
};

Attributes
style of type CSSStyleDeclaration, readonly
The style attribute.

5.3. CSS Extended Interfaces

The interfaces found within this section are not mandatory. A DOM application can use the hasFeature method of the DOMImplementation interface to determine whether they are supported or not. The feature string for all the extended interfaces listed in this section is "CSS2".

The following table specifies the type of CSSValue used to represent each property that can be specified in a CSSStyleDeclaration found in a CSSStyleRule for a CSS Level 2 style sheet. The expectation is that the CSSValue returned from the getPropertyCSSValue method on the CSSStyleDeclaration interface can be cast down, using binding-specific casting methods, to the specific derived interface.

For properties that are represented by a custom interface (the valueType of the CSSValue is CSS_CUSTOM), the name of the derived interface is specified in the table. For properties that consist of lists of values (the valueType of the CSSValue is CSS_VALUE_LIST), the derived interface is CSSValueList. For all other properties (the valueType of the CSSValue is CSS_PRIMITIVE_VALUE), the derived interface is CSSPrimitiveValue.

If width is CSS_IDENT, this attribute contains the string representation of the ident, otherwise it contains an empty string.

widthType of type unsigned short, readonly
A code defining the type of the width of the page. It would be one of CSS_EMS, CSS_EXS, CSS_PX, CSS_CM, CSS_MM, CSS_IN, CSS_PT, CSS_PC or CSS_IDENT.

Methods
getHeightSize
This method is used to get the float value in a specified unit if the heightType represents a length. If the float doesn't contain a float value or can't be converted into the specified unit, a DOMException is raised. If only the width value has been specified, the height value is the same.
Parameters
hType of type float
The height unit.

Return Value

float

The float value.

Exceptions

DOMException

INVALID_ACCESS_ERR: Raised if the property doesn't contain a float or the value can't be converted.

getWidth
This method is used to get the float value in a specified unit if the widthType represents a length. If the float doesn't contain a float value or can't be converted into the specified unit, a DOMException is raised.
Parameters
wType of type float
The width unit.

Return Value

float

The float value.

Exceptions

DOMException

INVALID_ACCESS_ERR: Raised if the property doesn't contain a float or the value can't be converted.

setHeightSize
This method is used to set the height position with a specified unit. If the widthType is not a length, it sets the width position to the same value.
Parameters
hType of type unsigned short
The height unit.

value of type float
The new value.

Exceptions

DOMException

INVALID_ACCESS_ERR: Raised if the specified unit is not a length or a percentage.

NO_MODIFICATION_ALLOWED_ERR: Raised if this property is readonly.

No Return Value

setIdentifier
Sets the identifier.
Parameters
ident of type DOMString
The new identifier.

Exceptions

DOMException

SYNTAX_ERR: Raised if the identifier has a syntax error and is unparsable.

NO_MODIFICATION_ALLOWED_ERR: Raised if this property is readonly.

No Return Value

setWidthSize
This method is used to set the width position with a specified unit. If the heightType is not a length, it sets the height position to the same value.
Parameters
wType of type unsigned short
The width unit.

value of type float
The new value.

Exceptions

DOMException

INVALID_ACCESS_ERR: Raised if the specified unit is not a length or a percentage.

NO_MODIFICATION_ALLOWED_ERR: Raised if this property is readonly.

No Return Value

Interface CSS2Properties (introduced in DOM Level 2)

The CSS2Properties interface represents a convenience mechanism for retrieving and setting properties within a CSSStyleDeclaration. The attributes of this interface correspond to all the properties specified in CSS2. Getting an attribute of this interface is equivalent to calling the getPropertyValue method of the CSSStyleDeclaration interface. Setting an attribute of this interface is equivalent to calling the setProperty method of the CSSStyleDeclaration interface.

A compliant implementation is not required to implement the CSS2Properties interface. If an implementation does implement this interface, the expectation is that language-specific methods can be used to cast from an instance of the CSSStyleDeclaration interface to the CSS2Properties interface.

If an implementation does implement this interface, it is expected to understand the specific syntax of the shorthand properties, and apply their semantics; when the margin property is set, for example, the marginTop, marginRight, marginBottom and marginLeft properties are actually being set by the underlying implementation.

When dealing with CSS "shorthand" properties, the shorthand properties should be decomposed into their component longhand properties as appropriate, and when querying for their value, the form returned should be the shortest form exactly equivalent to the declarations made in the ruleset. However, if there is no shorthand declaration that could be added to the ruleset without changing in any way the rules already declared in the ruleset (i.e., by adding longhand rules that were previously not declared in the ruleset), then the empty string should be returned for the shorthand property.

For example, querying for the font property should not return "normal normal normal 14pt/normal Arial, sans-serif", when "14pt Arial, sans-serif" suffices. (The normals are initial values, and are implied by use of the longhand property.)

If the values for all the longhand properties that compose a particular string are the initial values, then a string consisting of all the initial values should be returned (e.g. a border-width value of "medium" should be returned as such, not as "").

For some shorthand properties that take missing values from other sides, such as the margin, padding, and border-[width|style|color] properties, the minimum number of sides possible should be used; i.e., "0px 10px" will be returned instead of "0px 10px 0px 10px".

If the value of a shorthand property can not be decomposed into its component longhand properties, as is the case for the font property with a value of "menu", querying for the values of the component longhand properties should return the empty string.
