[css-sizing] Percentage margins and intrinsic sizes · Issue #347 · w3c/csswg-drafts (original) (raw)

Testcase: http://software.hixie.ch/utilities/js/live-dom-viewer/?saved=4345

Gecko renders as an author would expect: float is shrink-wrapped around its content with no overflow, and margins are 25% of their containing block. Blink and Edge overflow.

According to author > implementer > spec, we should all follow Gecko's lead here, but that requires buy-in from everyone else. :)
