=== 2018 Priorities ===
These are *in progress* 2018 Priorities for CSS features in Firefox.
* Bugzilla: https://bugzilla.mozilla.org/show_bug.cgi?id=1424418
* Bugzilla: https://bugzilla.mozilla.org/show_bug.cgi?id=1424418
* Some public input: https://twitter.com/t/status/939273644043366400
* Subsequently discussed by the Platform Layout team at [[Yallhands]] in Austin, Texas (further adjustments are likely)
==== Close to shipping ====
These features have implementations that are already well in progress and thus it is a priority to finish them and ship.
==== Grid Level 2 ====
Grid Level 2, in particular subgrid (use-cases, a11y implications)
* [https://drafts.csswg.org/css-grid-2/ CSS Grid level 2] ([https://www.w3.org/TR/css-grid-2/ W3C WD]) specifically [https://bugzilla.mozilla.org/buglist.cgi?quicksearch=subgrid Bugzilla bugs for subgrid]
* implementing, specification design may change accordingly
* see also for quick use-cases / tutorial:
** http://fantasai.inkedblade.net/style/discuss/subgrid-markup/
* medium mobile potential impact, different grid layouts for different responsive use-cases


=== To Be Reprioritized ===
==== Values and Units 3 ====

=== 2018 Medium Priorities ===
2018 medium priorities are "maybe" items that we're not sure we can get to in 2018, but would really like to (had a lot of interest during [[yallhands]]).

=== 2018 Lower Priorities ===
Features or areas that are lower priority based on a number of factors.
=== Actively Implementing ===
Beyond the above priorities, we should continue to actively implement, fix bugs on the following:
* [[Stylo]] ([https://bugzilla.mozilla.org/show_bug.cgi?id=1243581 metabug])
==== Flexbox ====
Mozilla has a pretty solid complete [https://www.w3.org/TR/css-flexbox-1/ Flexbox] (W3C CR, just waiting on feature-interaction tests to go PR) implementation. We are working on some fixes to make it even better, e.g.
* [https://bugzilla.mozilla.org/show_bug.cgi?id=1055888 Metabug for to-be-implemented spec changes]
==== Grid ====
* [https://drafts.csswg.org/css-grid/ CSS Grid] ([https://www.w3.org/TR/2017/CR-css-grid-1-20170509/ CR]) [https://bugzilla.mozilla.org/show_bug.cgi?id=1312610 metabug]

==== Shipped and evaluate follow up ====
===== Variable Fonts =====
<span id="Fonts_Level_4">Fonts Level 4</span> for Variable Fonts support in particular:

=== 2019 Needs Reprioritizing ===
These are all items we made progress in 2018 (in some cases shipping features or large portions there of) and need to re-evaluate what’s left (if anything) for 2019
