# Interface ViewCSS

All Superinterfaces:
  `AbstractView`

public interface ViewCSS extends AbstractView
This interface represents a CSS view. The `getComputedStyle` method provides a read only access to the computed values of an element.

The expectation is that an instance of the `ViewCSS` interface can be obtained by using binding-specific casting methods on an instance of the `AbstractView` interface.

Since a computed style is related to an `Element` node, if this element is removed from the document, the associated `CSSStyleDeclaration` and `CSSValue` related to this declaration are no longer valid.

See also the Document Object Model (DOM) Level 2 Style Specification.

Since:
  1.4, DOM Level 2
