Right now it sounds like "auto" would act as "inherit, unless a transform is applied in which case flat" which still seems a bit confusing to me. For example, it seems unintuitive that these two examples would produce different results: > > <div style="transform-style: preserve-3d; transform: rotateX(30deg);"> > <div> > <div> > <div> > <div style="transform-style: preserve-3d; transform: rotateX(30deg);"> > > <div style="transform-style: preserve-3d; transform: rotateX(30deg);"> > <div> > <div style="transform: scale(1)"> > <div> > <div style="transform-style: preserve-3d; transform: rotateX(30deg);"> > > Thanks, > -Matt > > [1] http://lists.w3.org/Archives/Public/www-style/2014Feb/0783.html Making it inherited is an interesting suggestion; I’d have to think about that. The performance characteristics are obviously a concern for documents with html { transform-style: preserve-3d; } but it’s possible that UAs could avoid allocating additional resources for elements with no 3d-transformed descendants in this kind of content. I’m currently struggling to figure out how to spec transform-style to avoid an issue noted in that Google doc where a single transformed element renders on top of everything else (but in current UAs, can be obscured by elements with higher z-index).
