What are pros and cons to add line-height to body { }?

Answer 1

It just depends. If you put it in the body then you get to be lazy and not worry about ever doing it again, but your going to lose control because everything on the page will have the line-height set to 1.5. Whereas if you declared it in each tag, you gain lots of control, but will have to do more work.

Personally I would go for the tag-by-tag solution, but I'm a control freak, so...

Answer 2

put it where it's appropriate

• if you want line-height: 1.5 on everything within the body, put in on the body

• if you only want line-height: 1.5 on everything in the main content area, put it on the div id="MainContent"

etc.
