I'm presently working in a much improved Kindle version of the World Famous (in my world) C# Yellow Book. Because the book has been written and upgraded over a number of versions the text formatting is a bit of a mess behind the scenes. It's taking a while to sort out.
I changed the style-sheet to make it a bit easier to see the code embedded in the text and got a preview page that I quite like above. With a bit of luck it should be finished in a week or so.
