CSS Logical Properties
Introduces logical properties and values that provide the author with the ability to control layout through logical, rather than physical, direction and dimension mappings.
Logical properties are now on our backlog, with a high priority. You can track status changes at https://dev.modern.ie/platform/status/csslogicalpropertieslevel1/

Exists in all other major browser why not edge?

+1 Any site that has a degree of language support would clear up a lot of code cruft by being able to use logical properties rather than loading language specific css files/classes/etc.

Just to keyword stuff this (I had a few suggestions merged into this which had keywords that are not here for searching), I was looking for margin-start, margin-end, text-align:start, text-align:end properties and values to allow for better right to left (RTL) styling or display.
The title of this suggestion led me to find the related spec http://dev.w3.org/csswg/css-logical-props/
