Csswg-drafts: [css-box-3] Should we move the border property defs from css-backgrounds-3 to css-box-3?

[fantasai]

Now that we've trimmed down the box module, deferring box generation to css-display and block layout to a forthcoming css-block module, should we move the border properties from css-backgrounds-3 to css-box-3?

Pros: Makes more sense?
Cons: They've been in css-backgrounds-3 for more than a decade.

Discuss!

What about a note in css-box-3 mentioning that you might expect the properties there, but for historical reasons they're over in backgrounds?

IMHO, borders belong where they currently are more than just for historical reasons. The only aspect of borders that effectively participates in the box model construction seems to be the _size_ of the _border area_, that is, border-width. Other border aspects (border-color and border-style, let alone border-image) are about _rendering_ borders, not about box geometry. I believe it makes sense to keep those aspects together with other rules of _painting different areas_ of the element (like background-clip/-origin, which also refer to box model parts). A note and a cross-reference would be a great solution for me.

OK. There was a cross-reference from the intro, but I added a dedicated section for it. @astearns @SelenIT Let me know if this looks good to you! https://drafts.csswg.org/css-box-3/#borders

Looks fine to me. I’d probably use “describe” or “indicate” rather than “delineate,” but I‘ll leave that up to you.

Looks great! Only the comma between "...the edges of the box" and "The border properties..." looks like a minor typo (shouldn't it be a full stop)?
