It seems like a very medium-specific attribute.

Why wouldn't this be a CSS issue? That's the layer of the Web platform 
where we put presentationa-specific things.

But in this particular case, why do we need authors to explicitly say 
anything about the direction? Why can't you just be vertical if you're 
tall, and horizontal if you're wide? I don't understand why anyone would 
ever want a tall horizontal slider.

If you're making proprietary pseudo-elements for parts of the slider while 
waiting for Web Components to be ready to do this, just have different 
pseudos for the two orientations.
