But also smart phones are computers. They just have a different primary input. Yes, their original design was consumption focused, but that hasn't been the case for a while now unless you let it be. See attached. Lots gets created on phones you just wouldn't know.
That said the web is the most portable format, when designed with even the smallest consideration, scales pretty well to all devices.
