Yeah Frank I think you're right it must have something to do with the newer HTML 5 doctype. I see under the older doctypes it still works but for 5 looks like you need to style those. Curious, I thought even with depreciated tags it parsed legacy.
Which made me notice RSD doesn't use a shiv either... I take it the focus in RSD is only up to date browsers, which I'm okay with 'bout time we moved on, but it's good to know.
One thing I did see going over the HTML generation is how important it is to semantic class even generic text, that is building out of hand already with only a couple of pages in the main CSS and I missed that one. I was assuming that basic was done for you in the coffeeginder sheet. I did do type for going to verdana from arial / helv which is neat but you got to keep an eye on the span text styles.
