"I often say that fonts are to type what voice is to speech. Typeface, font weight, italic,
and other typographic effects not only help designers to guide a visitor's eye around the
page, but they also add a layer of meaning."
Jason Cranford Teague in CSS3: Visual QuickStart Guide, Fifth Edition

I approached this excercise a little backwards. Not having read all the instructions (as usual) and also having just downloaded my screen ruler, I started by experimenting with what setting for pixel size would give an actual half-inch size eye, and then continued to use the ruler to calculate the picas, points etc. When I finally put in the CSS value font-size = .5in, that character was much smaller than all the others - which was a surprise to me. That started me down a road in an effort to understand what was going on and I learned more than I want to know about WXGA aspect ratio, dpi, monitors and a host of other stuff I've already forgotten. Richard Mason's article The CSS Inch finally cleared it up for me. So here are my results....
