William Ockham · 03-30-2013, 01:15 PM

I am developing some CSS snippets for KF8 to enable device detection from within Kindle ebooks. The most obvious use case for this is for authors who wish to display color graphics on the Kindle Fire family of devices while displaying greyscale graphics for the E Ink Kindles. I will be placing this CSS in the public domain when I've verified that it works properly.

I am using CSS media queries that depend on the hardware on the device. That means that I cannot test these on the Previewer and I do not have access to every KF8-compatible Kindle device. I am looking for volunteers to load the attached .mobi file on their Kindle Fire HD and report the results.
When you open the attached file (which is the first chapter of Moby Dick), you should see something like this:

Chapter 1: Looming

This is a 7 inch Kindle Fire HD.

device pixel ratio: 1.3

device-height: 1280

device-width: 8000

Call me Ishmael....

Obviously, the correct device and hardware results should be displayed, i.e. if you have a Kindle Fire HD 8.9", the second line will say "This is an 8.9 inch Kindle Fire HD."

I have already had a good response from folks with the Kindle E Ink devices and Kindle apps on another thread, but none from Fire HD owners. I would greatly appreciate it if a few of you would load this file and reply back to this thread with the results. I especially need to know if the HD devices report incorrect or incomplete results. For example, the first gen Kindle Fire does not report device-height or device-width.

What do you get for participating this research? My gratitude and the warm fuzzy feeling of helping to improve the quality of Kindle ebooks. Participants will be listed in the credits (CSS comments) as testers, if they wish.
