DOM Level 2 CSS

Synopsis

String item(unsigned long index);

Arguments

index

The position of the desired CSS attribute name.

Returns

The name of the CSS attribute at index, or the empty string if index is negative or greater than or equal to the length property.

Description

The CSSStyleDeclaration interface represents a collection of CSS style attributes and their values. This method allows you to query the name of the CSS attribute by position and, in conjunction with the length property, allows you to iterate through the set of CSS attributes specified in this style declaration. Note that the order of CSS attributes as returned by this method does not necessarily correspond to the order in which they appear in the document or style sheet source.

As an alternative to this item( ) method, JavaScript allows you to simply treat a CSSStyleDeclaration object as an array of CSS attribute names and use standard square-bracket array syntax to obtain the attribute name at a specified position.
