Flex column on small viewport

[yoshuawuyts]

It'd be nice to be able to set flex-direction based on a viewport:

On desktop I want side-by-side columns:

But on mobile I'd like to stack them:

Being able to set flex-direction based on viewport would be heaps helpful for flexbox reflows. I hope this makes sense. Thanks!

Several people have asked for this so it might be worth adding in. If I want stacked items on mobile I tend to just leave them display block and use sm-flex etc on the parent.

Oh that's pretty smart - I'll use that workaround for now then ^__^
