I also made sure to only include pseudo classes that KindleGen 2.8 compiles without displaying warnings. For example, both the K3 and the Kindle for PC app also support :before with auto-incrementing counters just fine, however, since KindleGen 2.8 displayed a W28002: CSS style specified in content is not supported by Kindle readers. warning for them, I didn't include them.
Just to be on the safe side, I also added a short disclaimer to my initial post. |
Hey, Doitsu:
Actually, I'd note that in my opinion, K4PC is not one of the lowest common denominators. It displays some things (like the NCX) that aren't displayable on other Amazon "devices." I'd wonder if any of those would work in the Paperwhite, and, of course, with pseudo-classes like "first-letter" and child classes do you have any possibility of creating any fallback media queries for the earlier, K7 devices? Or, because K7 doesn't really "use" CSS, does any fallback coding get ignored? Just a question. (I mean, hell, last I looked, even Nook didn't support the pseudo-classes.) I'm very appreciative of the testing and the results!
I'd love to use pseudo-classes and I'd really love to use the nth for table coloration, but...I
think that would leave the K7 looking pretty damn barebones. We usually go to some lengths to ensure that we provide fallback styling for any K8 elements that won't "fly" on the K7, even to creating fallback styling for images that float in K8 but not in K7. I'd have to see if the fallback could indeed "fall back" and make something for the K7. Interesting.
