If you read something about CSS3 Selectors, then what is actually being described is something that is part of the CSS Selectors Level 3 specification. […] The CSS Working Group is now working on Selectors Level 4 with new proposed features plus the selectors that were part of Level 3 (and CSS 1 and 2). It’s not CSS4, but Level 4 of a single specification. One small part of CSS.
