Interface ICSSSelector

All Superinterfaces:

ICSSNode, ISourceLocation

All Known Implementing Classes:

CSSSelector

public interface ICSSSelector
extends ICSSNode

Model for CSS3 selectors. A ICSSRule has one or many selectors connected by combinators. Currently, only descendant combinator is supported.

A selector can optionally have one or many ICSSSelectorCondition's.

Some of the W3C specifications and API might call this a "simple selector". Since we do not implement the whole W3C SAC API stack, there's no concept of "complex" selector. That's why it is called a "selector" instead of a "simple selector".
