The current specification allows us to name the different tracks. Here is the grid-definition-{rows|columns} syntax: <track-list> => [ [ <string> ]* <track-group> [ <string> ]* ]+ | none <track-group> => <track-minmax> | [ repeat( <positive-integer> , [ [ <string> ]* <track-minmax> [ <string> ]* ]+ ) ] We also would need to extend grid-position-{row|column} to accept <string>.
All the dependent bugs were fixed, closing this now.
