Bug or not (it at least partially is), it's been part of WK/Chrome's transform implementation since it first shipped, and the web depends on that behavior as a "promote to a layer" perf hack. (It also has implications on text anti-aliasing, iirc.) We don't simplify `translate3d()` into a `translate()` if it has a 0 z argument, or vice versa. The distinction is even maintained in TypedOM, which distinguishes between an unpassed `z` argument to CSSTranslate and a passed `0` value, and similar for the other 2d-and-3d constructors: <https://drafts.css-houdini.org/css-typed-om/#dom-csstranslate-csstranslate> So far, I've carefully kept the various transform things consistent in this quirk, and I'd like to maintain that. I don't think we should drop it from some syntax forms and not others, because that makes it confusing to predict which behavior you're going to get in WK/Chrome browsers. If we want to remove it, I'd like to remove it from *all* transform syntaxes. -- GitHub Notification of comment by tabatkins Please view or discuss this issue at https://github.com/w3c/csswg-drafts/issues/3305#issuecomment-539694490 using your GitHub account
