Summary: We intend to ship CSS overflow:clip in v81, which is the standardized version of a prefixed value (-moz-hidden-unscrollable) that we already ship. The prefixed value becomes an alias for the new value. The standardized value is mostly compatible, but there are some differences. Most notably, we now support clipping in one axis and overflowing in the other (i.e. 'clip' can be combined with 'visible' in the overflow-x/y properties).

We've shipped the prefixed version of this value since forever and any web-compat issues are unlikely. DevTools bug: N/A Other browsers: It's not implemented in Blink/WebKit yet: https://bugs.chromium.org/p/chromium/issues/detail?id=966283 https://bugs.webkit.org/show_bug.cgi?id=198230 Blink appears to show positive signals in: https://github.com/w3c/csswg-drafts/issues/1971 Web-platform-tests: Yes, some already exist and I've added more. Secure contexts: This will not be restricted to secure contexts, like many other CSS features. Is this feature enabled by default in sandboxed iframes? Yes, like many other CSS features. Credit also goes to Jeremy Ir who implemented the initial version of the style system changes for this feature. /Mats _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
