Specification

https://github.com/w3c/csswg-drafts/issues/10209#issuecomment-2221005001

Summary

The CSSWG resolved to rename this property from `inset-area` to `position-area`. See the CSSWG discussion here: https://github.com/w3c/csswg-drafts/issues/10209#issuecomment-2221005001 Chrome disagrees with this change, but would like to ship an interoperable implementation. We will ship the new property name, `position-area`, as a synonym for `inset-area` first. Then after a suitable amount of time, we will remove `inset-area`. The latter removal will be done under a separate Intent.

Risks

Interoperability and Compatibility

There is a compat risk with this rename, since the old name of `inset-area` is in use, with an 0.02% use counter: https://chromestatus.com/metrics/css/timeline/popularity/781 We will need to ship the new name, `position-area`, first, and issue deprecation warnings for the old name, `inset-area`, to give developers time to change. This intent to ship is about shipping `position-area` as a synonym for `inset-area`. We'll issue a separate I2D for removing the `inset-area` property.

Anticipated spec changes

Open questions about a feature may be a source of future web compat or interop issues. Please list open issues (e.g. links to known github issues in the project for the feature specification) whose resolution may introduce web compat/interop risk (e.g., changing to naming or structure of the API in a non-backward-compatible way).

Just to clarify: this intent is to add `position-area` which is a drop in replacement/alias for `inset-area`. The latter is being deprecated via another intent. Is this correct?

Thanks,

Vlad

That's exactly right, yes. The intent to deprecate the old name (inset-area) is this one.

Thanks,

Mason

LGTM1 to add `position-area`, since it is an alias for `inset-area` that is shipped and is being deprecated.
