07:04:55 dbaron, you asked in IRC awhile back if alphabetic | ideographic | central were stable enough to implement 07:05:01 dbaron, they're taken from SVG https://www.w3.org/TR/SVG11/text.html#BaselineAlignmentProperties 07:05:09 dbaron, so yeah, I can't imagine we could change them :) 07:05:28 dbaron, the only thing that's really new is that we defined vertical-align as a shorthand of alignment-baseline 07:05:38 dbaron, and allowed it to take alignment-baseline keywords
