## 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is removed from the document, the associated `CSSStyleDeclaration` and `CSSValue` related to this declaration are no longer valid.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:
    DOM Level 2
