Privacy Review Request for CSS Box Level 3

Hello!

CSS WG requests review of CSS Box Model Module Level 3
   https://www.w3.org/TR/css-box-3/

This fairly short specification describes the margin and padding properties, 
which create spacing in and around a CSS box, and defines a bunch of 
terminology used throughout the CSS layout specs. Changes since CSS2 are 
summarized in
   https://www.w3.org/TR/css-box-3/#changes
and basically consist of
   * updating the prose to account for vertical writing modes
   * defining a shared list of box-edge keywords for use in other properties
There are no new features.

I think there's probably zero interesting things here for you, since it's 
really just a redrafting of a very basic piece of CSS2, but since we're 
planning to request a CR transition soon I am sending a formal review request!

Please raise any issues in the csswg GitHub repo:
    https://github.com/w3c/csswg-drafts/issues
and let us know when you have completed your review.

Thanks!
