I've known about this method for a long while (back as early as 2004), but I've always found it easier to actually mock it up in HTML/CSS and then make changes on the fly. It might be my personal skill level that makes the difference, but it worked out better for me.

(My favorite design sessions remain the ones where I sat in a room, projecting my laptop onto a screen, and speed-editing CSS and PHP while my boss made suggestions at the front of the room. And then I'd go, "So, like this?" and refresh.)

Not really recommending it so much as saying it's a thing that can be done.

Yeah that's a good point. Your approach is getting easier and easier now with stuff like Bootstrap washing away CSS complexity...
