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 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.

### methods

- CSSStyleDeclaration ( )

  returns ctor

- CSSStyleDeclaration (other)

  returns ctor

  Argument | Type | Default
  --- | --- | ---
  other | DOM.CSSStyleDeclaration |

- CSSStyleDeclaration (impl)

  returns ctor
  Not implemented

  Argument | Type | Default
  --- | --- | ---
  impl | CSSStyleDeclarationImpl |

- cssText ( )

  returns DOM.DOMString

  The parsable textual representation of the declaration block (including 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.

- getPropertyCSSValue (propertyName)

  returns DOM.CSSValue

  Argument | Type | Default
  --- | --- | ---
  propertyName | DOM.DOMString |

  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.

  propertyName - The name of the CSS property. See the CSS property index .

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

- getPropertyPriority (propertyName)

  returns DOM.DOMString

  Argument | Type | Default
  --- | --- | ---
  propertyName | DOM.DOMString |

  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.

  propertyName - The name of the CSS property. See the CSS property index .

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

- getPropertyValue (propertyName)

  returns DOM.DOMString

  Argument | Type | Default
  --- | --- | ---
  propertyName | DOM.DOMString |

  Used to retrieve the value of a CSS property if it has been explicitly set within this declaration block.

  propertyName - The name of the CSS property. See the CSS property index .

  Returns 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.

- handle ( )

  returns CSSStyleDeclarationImpl
  Not implemented

  Internal not part of the DOM

- isNull ( )

  returns bool

- item (index)

  returns DOM.DOMString
  Not implemented

  Argument | Type | Default
  --- | --- | ---
  index | unsigned long |

  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.

  index - Index of the property name to retrieve.

  Returns The name of the property at this ordinal position. The empty string if no property exists at this position.

- item (index)

  returns DOM.DOMString

  Argument | Type | Default
  --- | --- | ---
  index | unsigned long |

- length ( )

  returns unsigned long

  The number of properties that have been explicitly set in this declaration block.

- parentRule ( )

  returns DOM.CSSRule

  The CSS rule that contains this declaration block.

- removeProperty (propertyName)

  returns DOM.DOMString

  Argument | Type | Default
  --- | --- | ---
  propertyName | DOM.DOMString |

  Used to remove a CSS property if it has been explicitly set within this declaration block.

  propertyName - The name of the CSS property. See the CSS property index .

  Returns 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 valid CSS2 property.

  DOMException NO_MODIFICATION_ALLOWED_ERR: Raised if this declaration is readonly.

- setCssText (a0)

  returns Nothing

  Argument | Type | Default
  --- | --- | ---
  a0 | DOM.DOMString |

  see cssText CSSException SYNTAX_ERR: Raised if the specified CSS string value has a syntax error and is unparsable.

  DOMException NO_MODIFICATION_ALLOWED_ERR: Raised if this declaration is readonly.

- setProperty (propertyName, value, priority)

  returns Nothing

  Argument | Type | Default
  --- | --- | ---
  propertyName | DOM.DOMString |
  value | DOM.DOMString |
  priority | DOM.DOMString |

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

  propertyName - The name of the CSS property. See the CSS property index .

  value - The new value of the property.

  priority - The new priority of the property (e.g. "important" ).
