Feature: Additional utilities for width and height property

[lettuceDestroyer]

I think it would be helpful to have the possibility to set the width and height of an element depending on the viewport. At the moment it is only possible to set the width width like so: w-{25,50,75,100}.

To set the width/height of an element depending on the viewport we could set it to something like this: w-lg-50 or for the height: h-lg-50.

Would that be something that you see as useful? Could I try to implement it?
