Source Author or Organization: W3C

This is one "module" for the coming Cascading Style Sheets Level 3 (CSS3) specification. It describes the selectors (patterns that match to elements) that already exist in CSS1 and CSS2, and also extends the selectors of CSS level 2 and proposes new selectors for CSS3 (and for other languages that may employ them).

CSS3 selectors introduces additional possiblities for useful selectors and pseudo-elements, including; styling support for unresolved XML entities, :default pseudo-class (represents the element that will be activated when the user presses the default activate key, useful for displaying what action will be taken if the user presses a key), pseudo-class inversion, the ability to select a range of children, and the ability to select every other child. There is also a rewriting of the selectors grammar since CSS2, and the specification now contains its own test suite.
