Summary This feature extends the existing contain-intrinsic-size syntax: none | <length> | auto && <length> to also include auto && none: none | <length> | auto && <length> | auto && none The reason for this change is the CSSWG resolution ( https://github.com/w3c/csswg-drafts/issues/8407#issuecomment-1440466558) to add an interaction between content-visibility: auto and contain-intrinsic-size. Specifically, that the former adds an "auto" keyword to the latter. For this to work, the resolution includes a note to extend contain-intrinsic-size syntax for "auto" to work with all existing keywords, including "none". Blink componentBlink>CSS <https://bugs.chromium.org/p/chromium/issues/list?q=component:Blink%3ECSS> TAG reviewNone TAG review statusNot applicable Risks Interoperability and Compatibility There is a risk of interoperability since the new syntax would previously be considered invalid, and result in a default behavior (equivalent to contain-intrinsic-size: none). Sites currently specifying contain-intrinsic-size: auto none would have their behavior change on Chromium after this feature launches. I estimate this risk to be low. *Gecko*: No signal This change was discussed in CSSWG and there were no objections to the resolutions *WebKit*: No signal This change was discussed in CSSWG and there were no objections to the resolutions *Web developers*: No signals *Other signals*: Ergonomics None. This is an improvement which will allow future work to improve ergonomics of content-visibility. Activation None. Security None. WebView application risks Does this intent deprecate or change behavior of existing APIs, such that it has potentially high risk for Android WebView-based applications? None Debuggability This feature is debuggable in the same way as other CSS features. Will this feature be supported on all six Blink platforms (Windows, Mac, Linux, Chrome OS, Android, and Android WebView)?Yes Is this feature fully tested by web-platform-tests <https://chromium.googlesource.com/chromium/src/+/main/docs/testing/web_platform_tests.md> ?Yes Flag nameCSSContainIntrinsicSizeAutoNone Requires code in //chrome?False Tracking bughttps://bugs.chromium.org/p/chromium/issues/detail?id=1453733 Estimated milestones M116 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).
