## 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 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 Style Sheets. 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.

## 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.

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, an implementation 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., 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.

  The items in the `CSSRuleList` are accessible via an integral index, starting from 0.

  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. If index is greater than or equal to the number of rules in the list, this returns `null`.
      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`
        The rule is a `CSSFontFaceRule`.

  Attributes
    `cssText` of type `DOMString`
      The parsable textual representation of the rule. This reflects the current state of the rule and not its initial value.
      Exceptions on setting

      `DOMException` | SYNTAX_ERR: Raised if the specified CSS string value has a syntax error and is unparsable. INVALID_MODIFICATION_ERR: Raised if the specified CSS string value represents a different type of rule than the current one. HIERARCHY_REQUEST_ERR: Raised if the rule cannot be inserted at this point in the style sheet. NO_MODIFICATION_ALLOWED_ERR: Raised if the rule is readonly.

    `parentRule` of type `CSSRule`, readonly
      If this rule is contained inside another rule (e.g. a style rule inside an @media block), this is the containing rule. If this rule is not nested inside any other rules, this returns `null`.
    `parentStyleSheet` of type `CSSStyleSheet`, readonly
      The style sheet that contains this rule.
    `type` of type `unsigned short`, readonly

Interface CSSStyleRule (introduced in DOM Level 2)

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

  IDL Definition

        // Introduced in DOM Level 2:
        interface CSSStyleRule : CSSRule {
                   attribute DOMString        selectorText;
                                                // raises(DOMException) on setting

          readonly attribute CSSStyleDeclaration  style;
        };

  Attributes
    `selectorText` of type `DOMString`
      The textual representation of the selector for the rule set. The implementation may have stripped out insignificant whitespace while parsing the selector.
      Exceptions on setting

      `DOMException` | SYNTAX_ERR: Raised if the specified CSS string value has a syntax error and is unparsable. NO_MODIFICATION_ALLOWED_ERR: Raised if this rule is readonly.

      The declaration-block of this rule set.
Interface CSSMediaRule (introduced in DOM Level 2)

  The `CSSMediaRule` interface represents a @media rule in a CSS style sheet. A `@media` rule can be used to delimit style rules for specific media types.

  IDL Definition

        // Introduced in DOM Level 2:
        interface CSSMediaRule : CSSRule {
          readonly attribute stylesheets::MediaList  media;
          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
      A list of all CSS rules contained within the media block.
    `media` of type `stylesheets::MediaList`, readonly
      A list of media types for this rule.
  Methods
    `deleteRule`
      Used to delete a rule from the media block.
      Parameters
      `index` of type `unsigned long`
        The index within the media block's rule collection of the rule to remove.
      Exceptions

      `DOMException` | INDEX_SIZE_ERR: Raised if the specified index does not correspond to a rule in the media rule list. NO_MODIFICATION_ALLOWED_ERR: Raised if this media rule is readonly.

      No Return Value
    `insertRule`
      Used to insert a new rule into the media block.
      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 media block's rule collection of the rule before which to insert the specified rule. If the specified index is equal to the length of the media blocks's rule collection, the rule will be added to the end of the media block.
      Return Value

      `unsigned long` | The index within the media block'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 media rule is readonly.

      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.
      Exceptions on setting

      `DOMException` | SYNTAX_ERR: Raised if the specified CSS string value has a syntax error and is unparsable. 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 all the properties in the declaration block including the removal or addition of properties.
      Exceptions on setting

      `DOMException` | SYNTAX_ERR: Raised if the specified CSS string value has a syntax error and is unparsable. NO_MODIFICATION_ALLOWED_ERR: Raised if this declaration is readonly or a property is readonly.

    `length` of type `unsigned long`, readonly
      The number of properties that have been explicitly set in this declaration block. The range of valid indices is 0 to length-1 inclusive.
    `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`
        The name of the CSS property. See the CSS property index.
      Return Value

      `CSSValue` | Returns the value of the property if it has been explicitly set for this declaration block. Returns `null` if the property has not been set.

      No Exceptions
    `getPropertyPriority`
      Used to retrieve the priority of a CSS property (e.g. the `"important"` qualifier) if the property has been explicitly set in this declaration block.
      Parameters
      `propertyName` of type `DOMString`
        The name of the CSS property. See the CSS property index.
      Return Value

      `DOMString` | A string representing the priority (e.g. `"important"`) if one exists. The empty string if none exists.

      No Exceptions
    `getPropertyValue`
      Used to retrieve the value of a CSS property if it has been explicitly set within this declaration block.
      Parameters
      `propertyName` of type `DOMString`
        The name of the CSS property. See the CSS property index.
      Return Value

      `DOMString` | Returns the value of the property if it has been explicitly set for this declaration block. Returns the empty string if the property has not been set.

      No Exceptions
    `item`
      Used to retrieve the properties that have been explicitly set in this declaration block. The order of the properties retrieved using this method does not have to be the order in which they were set. This method can be used to iterate over all properties in this declaration block.
      Parameters
      `index` of type `unsigned long`
        Index of the property name to retrieve.
      Return Value

      `DOMString` | The name of the property at this ordinal position. The empty string if no property exists at this position.

      No Exceptions
    `removeProperty`
      Used to remove a CSS property if it has been explicitly set within this declaration block.
      Parameters
      `propertyName` of type `DOMString`
        The name of the CSS property. See the CSS property index.
      Return Value

      `DOMString` | Returns the value of the property if it has been explicitly set for this declaration block. Returns the empty string if the property has not been set or the property name does not correspond to a known CSS property.

      Exceptions

      `DOMException` | NO_MODIFICATION_ALLOWED_ERR: Raised if this declaration is readonly or the property is readonly.

    `setProperty`
      Used to set a property value and priority within this declaration block.

        The new value of the property.
      `priority` of type `DOMString`
        The new priority of the property (e.g. `"important"`).
      Exceptions

      `DOMException` | SYNTAX_ERR: Raised if the specified value has a syntax error and is unparsable. NO_MODIFICATION_ALLOWED_ERR: Raised if this declaration is readonly or the property is readonly.

      No Return Value
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

      `CSS_CUSTOM`
        The value is a custom value.
      `CSS_INHERIT`
        The value is inherited and the `cssText` contains "inherit".
      `CSS_PRIMITIVE_VALUE`
        The value is a primitive value and an instance of the `CSSPrimitiveValue` interface can be obtained by using binding-specific casting methods on this instance of the `CSSValue` interface.
      `CSS_VALUE_LIST`
        The value is a `CSSValue` list and an instance of the `CSSValueList` interface can be obtained by using binding-specific casting methods on this instance of the `CSSValue` interface.

      A string representation of the current value.
      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. INVALID_MODIFICATION_ERR: Raised if the specified CSS string value represents a different type of values than the values allowed by the CSS property. NO_MODIFICATION_ALLOWED_ERR: Raised if this value is readonly.

    `cssValueType` 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).

      No Return Value
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`.

  The items in the `CSSValueList` are accessible via an integral index, starting from 0.

  IDL Definition

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

  Attributes
    `length` of type `unsigned long`, readonly
      The number of `CSSValues` in the list. The range of valid values of the indices is `0` to `length-1` inclusive.
  Methods
    `item`
      Used to retrieve a `CSSValue` by ordinal index. The order in this collection represents the order of the values in the CSS style property. If index is greater than or equal to the number of values in the list, this returns `null`.
      Parameters
      `index` of type `unsigned long`
        Index into the collection.
      Return Value

      `CSSValue` | The `CSSValue` at the `index` position in the `CSSValueList`, or `null` if that is not a valid index.

      No Exceptions
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.

  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.

### 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 using binding-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` 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

### 2.2.2. 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:

### 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`, readonly
      The style attribute.

## 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 with parameter 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. 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`. 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 conformant implementation of the CSS module 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.
