Kindle Format 8: with HTML5 and CSS3

Amazon announced Kindle Format 8 today, replacing Mobi 7.

Kindle Format 8 will support HTML5 and CSS3 -- good news for readers, who can now read far richer content on their Kindles, and developers, who already write HTML5 and CSS3. 

KF8 is presently supported only by Kindle Fire, but Amazon promises that upcoming e-ink Kindles and Kindle apps will begin to support KF8 in the next few months.
