"Great looking books." That's what Amazon is promising to deliver with Kindle Format 8 (KF8) -- a new, HTML5-based file format for Kindle books. According to the company, KF8 will allow publishers to produce picture books, comics and graphic novels with greater ease, thanks to the platform's rich formatting capabilities and design elements. In fact, this format brings more than 150 new formatting tools to the table, including fixed layouts, nested tables, sidebars and Scalable Vector Graphics, among others. It should be noted, however, that audio and video are not included on the list of supported HTML tags and CSS elements. At first, content creators will only be able to use KF8 for the Kindle Fire tablet, though Amazon says it'll gradually expand to its entire lineup of devices and apps "in the coming months." No word yet on when KF8 will become available as an update to Amazon's Kindle Publisher Tools suite, but you can find more details at the source link, below.
