Use CSS Logical Properties and Values?

[xfq]

Our specs use a lot of physical directions and dimensions, like this one. I think we can change them to logical properties and values. In this way, when the document is translated into languages with a different writing direction, the original style can be better preserved without modification.

I can craft a PR if you think this is a good idea.

I think the only language for which that would be required is Mongolian. Do we have a Mongolian translation of anything yet?

The benefit of leaving it as-is is greater backwards-compatibility, so unless we need to, it's probably best to leave things physical for now.

@fantasai what about changing the margin-left, border-left, etc properties, since we do have Arabic translations? It would save them some work, and show that we're eating our own dogfood.
