what is {font-size: 100.01%; }? and is i
The declaration body (or html) { font-size: 100.01% } compensates rounding errors, in particular in older versions of Opera and Safari. Both would otherwise display fonts that are too small.
A relative font-size (%, em) is always interpreted relative to the font size of the parent element. So it's not a bad idea to implement kind of a initial reset in the top element, which you can achieve with body {font-size: 100%}.
