The CSS Working Group has published an updated Working Draft of CSS Grid Layout. This CSS module defines a two-dimensional grid-based layout system optimized for user interface design.
This is publication is a major update: not only has the draft generally been reorganized and much of the prose rewritten to fill in missing details, avoid repetition, improve precision and terminology, and ensure alignment with Flexbox, but it’s switched to a new positioning model. The old grid layout model uses properties to indicate the starting row/column and the item’s span. The new grid layout model positions each edge of the item to a grid line.

The CSS3 Selectors module introduces three new attribute selectors, which are grouped together under the heading “Substring Matching Attribute Selectors”.
These new selectors are as follows:
[att^=val]– the “begins with” selector
[att$=val]– the “ends with” selector
[att*=val]– the “contains” selector
CSS3 Transitions are a presentational effect which allow property changes in CSS values, such as those that may be defined to occur on
:focus, to occur smoothly over a specified duration – rather than happening instantaneously as is the normal behaviour.
Transition effects can be applied to a wide variety of CSS properties, including
opacity, and many more. Keep reading for further details of supported properties.
Released on the 2nd February, the CSS3 Test, created by web standards aficionado Lea Verou, offers a quick and easy way to test and compare browser support for CSS3.
In a blog post accompanying the release of the test, Lea Verou outlines her motivation for building the test as follows:
