Well, it's taken 18 years to get this far... Should this draft pass muster, I'm very much looking forward to attempting to explain the differences, probably for the rest of my working life, between "justify-content", "align-content", "justify-self", "align-self", "justify-items", and "align-items". (I'm assuming by the time it's an actual W3C Recommendation, I'll actually understand the differences myself. No guarantees there.)
