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. The CSS
Object Model doesn't provide an access to the specified or actual values of the
CSS cascade.
See also the Document Object Model (DOM) Level 2 Style Specification.
