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.
