This is interesting and I've seen others use this short syntax, but it's never worked for me. In the case of Neat, one thing I lose is the margin-bottom of my paragraph tags when I don't close.

There's lot of great feedback in this thread, however, so maybe if I apply some of that, the margin won't go away.

Yeah, I used a mix of px, em, and other oddities, because I'm a bit old school, I suppose.
