Abstract
This specification defines the Document Object Model Level 2 Style Sheets and Cascading Style Sheets(CSS), a platform- and language-neutral interface that allows programs and scripts to dynamically accessand update the content and of style sheets documents. The Document Object Model Level 2 Style builds
on the Document Object Model Level 2 Core [DOM Level 2 Core] and on the Document Object Model
Level 2 Views [DOM Level 2 Views].

1.1. Introduction
The DOM Level 2 Style Sheet interfaces are base interfaces used to represent any type of style sheet. The
expectation is that DOM modules that represent a specific style sheet language may contain interfaces thatderive from these interfaces.
The interfaces found within this section are not mandatory. A DOM application may use the
hasFeature(feature, version) method of the DOMImplementation interface withparameter values "StyleSheets" and "2.0" (respectively) to determine whether or not this module issupported by the implementation. In order to fully support this module, an implementation must also
support the "Core" feature defined defined in the DOM 2 Core specification [DOM Level 2 Core]. Pleaserefer to additional information about conformance in the DOM Level 2 Core specification [DOM Level 2
Core].

1.2. Style Sheet Interfaces
This set of interfaces represents the generic notion of style sheets.
Interface StyleSheet (introduced in DOM Level 2)
The StyleSheet interface is the abstract base interface for any type of style sheet. It represents asingle style sheet associated with a structured document. In HTML, the StyleSheet interface
represents either an external style sheet, included via the HTML LINK element, or an inline STYLE
element. In XML, this interface represents an external style sheet, included via a style sheet
processing instruction.
IDL Definition// Introduced in DOM Level 2:interface StyleSheet {readonly attribute DOMString
attribute boolean
readonly attribute Nodereadonly attribute StyleSheet
readonly attribute DOMString
readonly attribute DOMString
readonly attribute MediaList
};

type;
disabled;
ownerNode;parentStyleSheet;href;
title;
media;

9

1.2. Style Sheet Interfaces

Attributes
disabled of type boolean
false if the style sheet is applied to the document. true if it is not. Modifying this
attribute may cause a new resolution of style for the document. A stylesheet only applies if
both an appropriate medium definition is present and the disabled attribute is false. So, if
the media doesn’t apply to the current user agent, the disabled attribute is ignored.
href of type DOMString, readonly
If the style sheet is a linked style sheet, the value of its attribute is its location. For inline
style sheets, the value of this attribute is null. See the href attribute definition for the
LINK element in HTML 4.0, and the href pseudo-attribute for the XML style sheet
processing instruction.
media of type MediaList [p.11] , readonly
The intended destination media for style information. The media is often specified in theownerNode. If no media has been specified, the MediaList [p.11] will be empty. See
the media attribute definition for the LINK element in HTML 4.0, and the media
pseudo-attribute for the XML style sheet processing instruction . Modifying the media list
may cause a change to the attribute disabled.
ownerNode of type Node, readonly
The node that associates this style sheet with the document. For HTML, this may be thecorresponding LINK or STYLE element. For XML, it may be the linking processing
instruction. For style sheets that are included by other style sheets, the value of this
attribute is null.
parentStyleSheet of type StyleSheet [p.9] , readonly
For style sheet languages that support the concept of style sheet inclusion, this attribute
represents the including style sheet, if one exists. If the style sheet is a top-level style sheet,or the style sheet language does not support inclusion, the value of this attribute is null.
title of type DOMString, readonly
The advisory title. The title is often specified in the ownerNode. See the title attributedefinition for the LINK element in HTML 4.0, and the title pseudo-attribute for the XML
style sheet processing instruction.
type of type DOMString, readonlyThis specifies the style sheet language for this style sheet. The style sheet language is
specified as a content type (e.g. "text/css"). The content type is often specified in theownerNode. Also see the type attribute definition for the LINK element in HTML 4.0,
and the type pseudo-attribute for the XML style sheet processing instruction.
Interface StyleSheetList (introduced in DOM Level 2)
The StyleSheetList interface provides the abstraction of an ordered collection of style sheets.
The items in the StyleSheetList are accessible via an integral index, starting from 0.
IDL Definition// Introduced in DOM Level 2:interface StyleSheetList {readonly attribute unsigned long
length;StyleSheet
item(in unsigned long index);};101.2. Style Sheet Interfaces

Attributes
length of type unsigned long, readonly
The number of StyleSheets [p.9] in the list. The range of valid child stylesheet indicesis 0 to length-1 inclusive.
Methods
item
Used to retrieve a style sheet by ordinal index. If index is greater than or equal to thenumber of style sheets in the list, this returns null.
Parametersindex of type unsigned longIndex into the collection
Return Value
StyleSheet[p.9]

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

No Exceptions
Interface MediaList (introduced in DOM Level 2)
The MediaList interface provides the abstraction of an ordered collection of media, without
defining or constraining how this collection is implemented. An empty list is the same as a list that
contains the medium "all".
The items in the MediaList are accessible via an integral index, starting from 0.
IDL Definition// Introduced in DOM Level 2:interface MediaList {attribute DOMString

mediaText;// raises(DOMException) on setting

readonly attribute unsigned long
length;DOMStringitem(in unsigned long index);void
deleteMedium(in DOMString oldMedium)raises(DOMException);void
appendMedium(in DOMString newMedium)raises(DOMException);};

Attributes
length of type unsigned long, readonly
The number of media in the list. The range of valid media is 0 to length-1 inclusive.
mediaText of type DOMString
The parsable textual representation of the media list. This is a comma-separated list of
media.
Exceptions on setting

11

1.2. Style Sheet Interfaces

DOMException

SYNTAX_ERR: Raised if the specified string value has a syntax
error and is unparsable.
NO_MODIFICATION_ALLOWED_ERR: Raised if this media
list is readonly.

Methods
appendMedium
Adds the medium newMedium to the end of the list. If the newMedium is already used, it
is first removed.
Parameters
newMedium of type DOMString
The new medium to add.
Exceptions
DOMException

INVALID_CHARACTER_ERR: If the medium contains
characters that are invalid in the underlying style language.
NO_MODIFICATION_ALLOWED_ERR: Raised if this list isreadonly.

No Return ValuedeleteMedium
Deletes the medium indicated by oldMedium from the list.
Parameters
oldMedium of type DOMString
The medium to delete in the media list.
Exceptions
DOMException

NO_MODIFICATION_ALLOWED_ERR: Raised if this list isreadonly.
NOT_FOUND_ERR: Raised if oldMedium is not in the list.

No Return Value
item
Returns the indexth in the list. If index is greater than or equal to the number of media
in the list, this returns null.
Parametersindex of type unsigned longIndex into the collection.
Return Value
DOMString

The medium at the indexth position in the MediaList, or null ifthat is not a valid index.

121.3. Document Extensions

No Exceptions

1.3. Document Extensions
Interface LinkStyle (introduced in DOM Level 2)
The LinkStyle interface provides a mechanism by which a style sheet can be retrieved from thenode responsible for linking it into a document. An instance of the LinkStyle interface can beobtained using binding-specific casting methods on an instance of a linking node(HTMLLinkElement, HTMLStyleElement or ProcessingInstruction in DOM Level
2).
IDL Definition// Introduced in DOM Level 2:interface LinkStyle {readonly attribute StyleSheet};

sheet;

Attributes
sheet of type StyleSheet [p.9] , readonly
The style sheet.
Interface DocumentStyle (introduced in DOM Level 2)
The DocumentStyle interface provides a mechanism by which the style sheets embedded in adocument can be retrieved. The expectation is that an instance of the DocumentStyle 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 DocumentStyle {readonly attribute StyleSheetList};

styleSheets;

Attributes
styleSheets of type StyleSheetList [p.10] , readonly
A list containing all the style sheets explicitly linked into or embedded in a document. For
HTML documents, this includes external style sheets, included via the HTML LINK
element, and inline STYLE elements. In XML, this includes external style sheets, included
via style sheet processing instructions (see [XML-StyleSheet]).

1.4. Association between a style sheet and a document.
HTML and Style Sheet Creation
A style sheet can be associated with an HTMLDocument in one of two ways:
By creating a new LINK HTML element (see the HTMLLinkElement interface in the [DOM
Level 2 HTML] and [HTML4.0]). The underlying style sheet will be created after the element is13

inserted into the document and both the href and the type attribute have been set in a way
indicating that the linked object is a style sheet.
By creating a new STYLE HTML element (see the HTMLStyleElement interface in the[DOM Level 2 HTML] and [HTML4.0]). The underlying style sheet will be created after theelement is inserted into the document and the type attribute is set in a way indicating that theelement corresponds to a style sheet language interpreted by the user agent.
HTML and Style Sheet Removal
Removing a LINK HTML element or a STYLE HTML element removes the underlying style sheet
from the style sheet collection associated with a document. Specifically, the removed style sheet is nolonger applied to the presentation of the document.
XML and Style Sheet Creation
A new style sheet can be created and associated with an XML document by creating a processing
instruction with the target ’xml-stylesheet’ [XML-StyleSheet] and inserting it into the document.
XML and Style Sheet Removal
Removing a processing instruction with a target of ’xml-stylesheet’ [XML-StyleSheet] removes theunderlying style sheet from the style sheet collection associated with a document. Specifically, theremoved style sheet is no longer applied to the presentation of the document.

2.1. 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 amechanism 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 inthis collection exposes the properties common to all style sheets referenced or embedded in HTML andXML documents; this interface is described in the Document Object Model Style Sheets [p.9] . 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 [p.16] interface. This
interface allows access to the collection of rules within a CSS style sheet and methods to modify thatcollection. 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 [p.18] interface.
The most common type of rule is a style declaration. The CSSStyleRule [p.20] interface that
represents this type of rule provides string access to the CSS selector of the rule, and access to theproperty declarations through the CSSStyleDeclaration [p.24] interface.
Finally, an optional CSS2Properties [p.40] 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 andactual style.

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

15

2.2. CSS Fundamental Interfaces

A DOM application may use the hasFeature(feature, version) method of the
DOMImplementation interface with parameter values "CSS" and "2.0" (respectively) to determine
whether or not this module is supported by the implementation. In order to fully support this module, animplementation must also support the "Core" feature defined defined in the DOM Level 2 Core
specification [DOM Level 2 Core] and the "Views" feature defined in the DOM Level 2 Views
specification [DOM Level 2 Views]. Please refer to additional information about conformance in the
DOM Level 2 Core specification [DOM Level 2 Core].
Interface CSSStyleSheet (introduced in DOM Level 2)
The CSSStyleSheet interface is a concrete interface used to represent a CSS style sheet i.e., astyle sheet whose content type is "text/css".
IDL Definition// Introduced in DOM Level 2:interface CSSStyleSheet : stylesheets::StyleSheet {readonly attribute CSSRuleownerRule;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 [p.17] , readonly
The list of all CSS rules contained within the style sheet. This includes both rule sets andat-rules.
ownerRule of type CSSRule [p.18] , readonly
If this style sheet comes from an @import rule, the ownerRule attribute will contain the
CSSImportRule [p.23] . In that case, the ownerNode attribute in the StyleSheet[p.9] 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 willcontain the Node.
Methods
deleteRule
Used to delete a rule from the style sheet.
Parametersindex of type unsigned long

Interface CSSCharsetRule (introduced in DOM Level 2)
The CSSCharsetRule interface represents a @charset rule in a CSS style sheet. The value of theencoding attribute does not affect the encoding of text data in the DOM objects; this encoding isalways UTF-16. After a stylesheet is loaded, the value of the encoding attribute is the value foundin 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 theencoding 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.

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 isexpected to provide access to all specified properties in the style sheet through theCSSStyleDeclaration interface. Furthermore, implementations that support a specific level of
CSS should correctly handle CSS shorthand properties for that level. For a further discussion ofshorthand properties, see the CSS2Properties [p.40] interface.
This interface is also used to provide a read-only access to the computed values of an element. See
also the ViewCSS [p.37] interface.
Note: The CSS Object Model doesn’t provide an access to the specified or actual values of the CSS
cascade.

Interface CSSPrimitiveValue (introduced in DOM Level 2)28

2.2. CSS Fundamental Interfaces

The CSSPrimitiveValue interface represents a single CSS value. This interface may be used todetermine the value of a specific style property currently set in a block or to set a specific styleproperty explicitly within the block. An instance of this interface might be obtained from the
getPropertyCSSValue method of the CSSStyleDeclaration [p.24] 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 toradians, 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 anumber; (see also the RGBColor [p.35] interface).

in the underlying style property. Hence, modifications made to the CSSPrimitiveValue [p.28]
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.

2.2.1. Override and computed style sheet

listStyle of type DOMString, readonlyThis attribute is used for the style of the list.
separator of type DOMString, readonlyThis attribute is used for the separator of the nested counters.

2.2.1. 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 usingbinding-specific casting methods on an instance of the AbstractView interface.
Since a computed style is related to an Element node, if this element is removed from the
document, the associated CSSStyleDeclaration [p.24] and CSSValue [p.27] related to thisdeclaration 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[p.24]

The computed style. The
CSSStyleDeclaration is read-only andcontains only absolute values.

No Exceptions
Interface DocumentCSS (introduced in DOM Level 2)This interface represents a document with a CSS view.

372.2.2. Style sheet creation

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 usingbinding-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 [p.24]

The override style declaration.

No Exceptions

2.2.2. Style sheet creation
Interface DOMImplementationCSS (introduced in DOM Level 2)This interface allows the DOM user to create a CSSStyleSheet [p.16] outside the context of adocument. There is no way to associate the new CSSStyleSheet with a document in DOM Level
2.
IDL Definition38

2.2.3. Element with CSS inline style// Introduced in DOM
Level 2:interface DOMImplementationCSS : DOMImplementation {CSSStyleSheetcreateCSSStyleSheet(in DOMString title,

raises(DOMException);};

Methods
createCSSStyleSheet
Creates a new CSSStyleSheet [p.16] .
Parameters
title of type DOMString
The advisory title. See also the Style Sheet Interfaces [p.10] section.
media of type DOMString
The comma-separated list of media associated with the new style sheet. See also the
Style Sheet Interfaces [p.10] section.
Return Value
CSSStyleSheet [p.16]

A new CSS style sheet.

Exceptions
DOMException

SYNTAX_ERR: Raised if the specified media string value has asyntax error and is unparsable.

2.2.3. 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 [p.24] , readonly
The style attribute.

392.3. CSS2 Extended Interface

2.3. CSS2 Extended Interface
The interface found within this section are not mandatory. A DOM application may use the
hasFeature(feature, version) method of the DOMImplementation interface withparameter values "CSS2" and "2.0" (respectively) to determine whether or not this module is supported by
the implementation. In order to fully support this module, an implementation must also support the "CSS"
feature defined defined in CSS Fundamental Interfaces [p.15] . Please refer to additional information
about conformance in the DOM Level 2 Core specification [DOM Level 2 Core].
Interface CSS2Properties (introduced in DOM Level 2)
The CSS2Properties interface represents a convenience mechanism for retrieving and setting
properties within a CSSStyleDeclaration [p.24] . 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 ofthis interface is equivalent to calling the setProperty method of the CSSStyleDeclarationinterface.
A conformant implementation of the CSS module is not required to implement the
CSS2Properties interface. If an implementation does implement this interface, the expectation isthat language-specific methods can be used to cast from an instance of theCSSStyleDeclaration [p.24] interface to the CSS2Properties interface.
If an implementation does implement this interface, it is expected to understand the specific syntax ofthe 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, thena 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".

40

2.3. CSS2 Extended Interface

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 thecomponent longhand properties should return the empty string.
