This specification defines the Document Object Model Events Level 3, a generic platform- and language-neutral event system which allows registration of event handlers, describes event flow through a tree structure, and provides basic contextual information for each event. The Document Object Model Events Level 3 builds on the Document Object Model Events Level 2. Learn more about the Rich Web Client Activity.

The Cascading Style Sheets (CSS) Working Group has published two Working Drafts:

• A Last Call Working Draft of CSS Flexible Box Layout Module. The specification describes a CSS box model optimized for user interface design. In the flex layout model, the children of a flex container can be laid out in any direction, and can "flex" their sizes, either growing to fill unused space or shrinking to avoid overflowing the parent. Both horizontal and vertical alignment of the children can be easily manipulated. Nesting of these boxes (horizontal inside vertical, or vertical inside horizontal) can be used to build layouts in two dimensions Comments are welcome through 03 July.
• The First Public Working Draft of CSS Box Alignment Module Level 3. This module contains the features of CSS relating to the alignment of boxes within their containers in the various CSS box layout models: block layout, table layout, flex layout, and grid layout. (The alignment of text and inline-level content is defined in CSS3TEXT and CSS3LINEBOX.) CSS is a language for describing the rendering of structured documents (such as HTML and XML) on screen, on paper, in speech, etc.
