Since I'm still trying to get my mind around this (and the w3 rules are
quite hard to parse IMO), I was just playing around with my own styles
when I noticed that the original base line-height value for this project
was set using %:
font-size: 100%;
This is taken directly from Eric Meyer's reset stylesheet
http://meyerweb.com/eric/tools/css/reset/index.html
And I always assume he knows what he's doing. Since he's also not
changing the font size (100% pretty much means "say the same"), is this
rule simply included to dictate the way line-height is calculated on
descendants?
