Re: justify-self not recognized?

Thanks for your CSS and HTML.

If you look here (since you mentioned Mozilla):
   https://developer.mozilla.org/en-US/docs/Web/CSS/justify-self
and scroll to the bottom you will see that the specification that covers
justify-self is still in "working draft" status. That means it is not yet
official CSS; only being considered.

You can confirm that here:
    https://www.w3.org/TR/css-align-3/
where you will see the following at the top:
W3C Working Draft, 23 April 2018
and "under "Status of this document" you will see:
<quote>
Publication as a Working Draft does not imply endorsement by the W3C
Membership. This is a draft document and may be updated, replaced or
obsoleted by other documents at any time. It is inappropriate to cite this
document as other than work in progress.

As it is not yet part of the standard I doubt that the validator will
support it. Also, as it is subject to change it is not yet safe (in my
opinion) for use in anything except a testing environment.

Walt
