Microsoft web browsers support the Selectors Level 3 specification [W3C-CSS3-Selectors], published 15 December 2009, with no variations, clarifications, or extensions.

The supported specification describes the selectors that already exist in CSS1 and CSS2, and further introduces new selectors for CSS3 and other languages that may need them. A selector is a pattern that matches against elements in a tree; it is used to select nodes in an XML document.
