Selectors API Level 1 is a W3C Recommendation

The Web Applications Working Group has published a W3C Recommendation of Selectors API Level 1. Selectors, which are widely used in CSS, are patterns that match against elements in a tree structure. The Selectors API specification defines methods for retrieving Element nodes from the DOM by matching against a group of selectors. It is often desirable to perform DOM operations on a specific set of elements in a document. These methods simplify the process of acquiring specific elements, especially compared with the more verbose techniques defined and used in the past. Learn more about the Rich Web Client Activity.
