[css-gaps-1] Initial editor's draft. #10393

[kbabbitt]

Major changes from the unofficial draft:

• Defer gap decoration areas out of Level 1
• Drop the direction-relative properties
• Generalize *-rule-break to apply to all container types
• Remove the join keyword from *-rule-outset and fold its behavior into *-rule-break
• Define algorithms for:
  • Determining gap decoration endpoints
  • Expanding repeaters in color/style/width properties

Drop the direction-relative properties

I can't remember, was this based on feedback from the working group?

It was based on feedback from the issue discussion.

#10393 (comment)

• (possibly?) add main-rule and cross-rule for Flexbox (personally I'd prefer to just use row-rule and column-rule)

#10393 (comment)

Me too. There is no main-gap or cross-gap property, so I don't think we need main-rule or cross-rule either.

Looks great overall, mostly just nits

Overall, looks good to me, as well, with a few suggestions below.
