fantasai has just created a new issue for https://github.com/w3c/csswg-drafts: == [css-anchor-position] Resolution of percentages: area or track? == The [Apple anchor positioning exploration](https://fantasai.inkedblade.net/style/specs/css-anchor-exploration/#anchor-based-positioning) included a rule: > Percentage values are relative to the size of the single track on the corresponding side of the anchor area (not to the entire anchor area). > > For example, if a box occupies the right and center tracks, then `left: 50%` will pin the left edge of the inset-modified containing block halfway through the center track; and `right: 50%` will pin the right edge of the inset-modified containing block halfway through the right-side track. The purpose of this adjustment was to enable common adjustments such as aligning the edge of a popover to the center of the anchor, or 1/3 of the way in, etc. The current spec follows the normal resolution rules, applying percentages against the whole area, which doesn't enable these common use cases.
