Method Details

addProperty

public void addProperty(Property p)

getCssText

public String getCssText()
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.

The CSS rule that contains this declaration block or null if this CSSStyleDeclaration is not attached to a CSSRule.
Specified by:
getParentRule in interface CSSStyleDeclaration

getPropertyCSSValue

public CSSValue getPropertyCSSValue(String propertyName)
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.
Specified by:
getPropertyCSSValue in interface CSSStyleDeclaration
Parameters:
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 null if the property has not been set.

getPropertyPriority

public String getPropertyPriority(String propertyName)
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.
Specified by:
getPropertyPriority in interface CSSStyleDeclaration
Parameters:
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.

public String getPropertyValue(String propertyName)
Used to retrieve the value of a CSS property if it has been explicitly set within this declaration block.
Specified by:
getPropertyValue in interface CSSStyleDeclaration
Parameters:
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.

item

public String item(int index)
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.
Specified by:
item in interface CSSStyleDeclaration
Parameters:
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.
