Thanks Wilbert, but I don't think I am explaining what exactly I need.
My client wants to be able to print the email and make sure the format of the email stays nice and pretty. Instead of getting wonky.
Thanks Richard, that makes sense. I also was curious about the size and line-height. I have never seen this short cut before. Although maybe it works for websites, I'm not sure it does for emails. font:14px/18px
