title: How to calculate REM for type?
body: <p>How do I convert PX into REM for my type? I've read Jonathan Snook's article about using REM, but he was using font-size:62.5%, which defaults to your font size to 10px (for easier calculating). How would I convert my PX units into REM if I was to use 100%, 75%, and so forth?</p>
