Comment (by raoulunger):

 I second that. I write plenty of code for CSS grid, and none of it is
 recognized by the editor. I keep having to convince it (after every edit)
 that they are not mistakes. I understand that CSS evolves, and that the
 editor will lag behind somewhat for that reason. But CSS grid has been
 around for quite some time now and is fully accepted by all browsers
 (except IE), and you would think expanding the list with allowed code
 should not be too difficult. We had an update of WP last week, but again
 no changes in this respect...
