Contact emails xin...@intel.com Spec https://drafts.csswg.org/css-logical-props/ Summary Implement {inline-,block-}size and {min-,max-}{inline-,block-}size, which are introduced by CSS Logical Properties.

The related properties are: inline-size, block-size , min-inline-size,min-block-size, max-inline-size, max-block-size

Motivation

Provide the author with the ability to control layout through logical, rather than physical, direction and dimension mappings.

Interoperability risk Firefox: Shipped Edge: No public signals Safari: No public signals Web developers: No signals

LGTM2

For others who haven't seen the related thread - these are just aliases of our existing prefixed -webkit-{min,max}-logical-{width,height} properties.

Unfortunately there don't appear to be any tests for this spec in csswg-test - the only hits I find are in vendor-imports/mozilla/ (maybe worth checking to see if we pass those tests once this is added?). Perhaps we have LayoutTests tests for -webkit-{min,max}-logical-{width,height} we could easily update and upstream to csswg-test?

Only partially related, but Mozilla people mentioned that they have CSS Grid tests that use those properties extensively, so maybe those could be useful as well (it will test both of the features, yes, but more tests are better than less tests ;)).

For reference, from the CSSWG thread:
https://lists.w3.org/Archives/Public/www-style/2016Dec/0065.html

It seems implied that they were ok with it for Firefox and presumably
are OK with it for us as well.
